Activists and Vulnerable Nations Condemn U.S. Arguments Against Climate Obligations at ICJ Hearing

Testimony from the United States during the ongoing International Court of Justice (ICJ) hearing on Wednesday evoked anger from climate activists and vulnerable nations, as the planet’s second-largest greenhouse gas emitter argued against nations being legally obligated to take measures to fight the climate crisis.

The oral arguments were part of the historic climate hearing in The Hague, where climate-vulnerable countries like Vanuatu and other small island nations are calling for rich polluters that are most responsible for global heating to be held accountable.

“The International Court of Justice’s proceedings are a profound moment in global climate accountability. The hearings elevate science to the forefront, ensuring international law reflects the realities of climate impacts and the urgent need for global action,” said Dr. Delta Merner, lead scientist for the Union of Concerned Scientists’ (UCS) Science Hub for Climate Litigation, in a press release from UCS. “Yet in today’s oral arguments, the United States — the world’s largest historical polluter of heat trapping emissions — resisted calls for climate accountability. Instead of taking responsibility for its contributions to the climate crisis, the United States used its 30-minute slot to downplay the role of the courts for global climate action, emphasize non-binding national commitments under the Paris Agreement, and reject the notion of historical responsibility.”

“By framing climate change as a collective action challenge without clear legal obligations for individual states, the United States dismissed the potential for redress or binding accountability measures that advance justice for climate-vulnerable nations,” Merner added.

In its arguments, the U.S. emphasized sticking with the 2015 and Paris Agreement and the United Nations Framework Convention on Climate Change, as well as other treaties, reported The Guardian.

“Any other legal obligations relating to climate change mitigation identified by the court should be interpreted consistently with the obligations states have under this treaty regime,” Margaret Taylor, legal adviser for the U.S. Department of State, told the ICJ judges, as The Guardian reported.

The response from climate activists illustrated the need for wealthy nations to be held accountable for their disproportionate contributions to the climate crisis, as well as their outsized evasion of responsibility.

“Once again, we witness a disheartening attempt by the U.S. to evade its responsibilities as one of the world’s largest polluters,” said Vishal Prasad, campaign director for the Pacific Islands Students Fighting Climate Change, as reported by The Guardian. “The U.S. is content with its business-as-usual approach and has taken every possible measure to shirk its historical responsibility, disregard human rights and reject climate justice.”

Other of the world’s largest fossil fuel economies and biggest greenhouse gas emitters — China, Australia and Saudi Arabia — also argued against being held legally accountable for the pollution they produce.

“It is absurd for the Biden administration to argue before the ICJ that countries do not have clear legal obligations to reduce carbon pollution, especially as it prepares to turn over the executive office to a proven climate denier like president-elect Trump, whose policies are likely to deeply harm U.S. climate action,” said Ashfaq Khalfan, climate justice director at Oxfam.

Vulnerable nations fought for years for rich polluters to be held accountable, and the UN responded by asking the ICJ to give an advisory opinion on the obligations of states in combating climate change, along with what the legal consequences would be if they do not do their part.

“The ICJ’s advisory opinion has the potential to reshape international climate governance by providing clear, authoritative guidance on nation’s obligations under existing law. This process showcases how the best available science can illuminate pathways to protect human rights, advance equity, and compel ambitious climate action,” Merner said in the press release. “In the face of stonewalling from major polluters, we applaud the leadership of Vanuatu and others for advancing this process. These proceedings must continue to center the voices of frontline communities.”

More than 100 countries and organizations are providing testimony over the 12-day hearings.

Advisory opinions by the ICJ are not binding, but nonetheless carry significant weight both legally and politically. The opinion of the court will be cited as an authoritative statement during future international climate negotiations and litigation.

Ralph Regenvanu, special climate change envoy for Vanuatu, on Wednesday expressed disappointment in the U.S. and other major polluters on behalf of his country.

“These nations, some of the world’s largest greenhouse gas emitters, have pointed to existing treaties and commitments that have regrettably failed to motivate substantial reductions in emissions… these treaties are essential, but they cannot be a veil for inaction or a substitute for legal accountability,” Regenvanu said, as The Guardian reported.

Vanuatu is leading the push for financial support and compensation for loss and damage for the countries that are most vulnerable to climate impacts — especially Pacific island nations — such as sea-level rise, flooding, drought and wildfires.

Taylor was dismissive of the ICJ weighing in on historic emitters being held responsible for their past pollution.

“An advisory proceeding is not the means to litigate whether individual states or groups of states have violated obligations pertaining to climate change in the past or bear responsibility for reparations… nor would it be appropriate to do so,” Taylor said, as reported by The Guardian.

There are three international courts of law responsible for providing advisory opinions concerning the climate crisis, including the ICJ, the Inter-American Court of Human Rights and the International Tribunal for the Law of the Sea (ITLOS).

Earlier this year, ITLOS found that nations have a legal obligation to control greenhouse gases as pollutants.

“By leveraging science and law together, the ICJ can help course-correct the international response to climate change, providing justice and hope for future generations as they endeavor to stave off some of the worst climate harms. No matter what the court decides, civil society must continue to push for decision-making guided by science and climate-vulnerable communities, as well as challenge the outsized political power wielded by fossil fuel interests seeking to obstruct and delay climate goals for the sake of their own bottom lines,” Merner said in the press release.

Wolves Will No Longer Be ‘Strictly Protected’ in Europe

Wolves in Europe will go from being “strictly protected” to “protected” next year after the Council of Europe backed a proposal by the European Union to downgrade their status.

Conservationists are concerned about the survival of the species, which bounced back after being on the edge of local extinction, reported The Guardian.

“This decision is a green light to shoot wolves, given by the international community in white gloves,” said Marta Klimkiewicz, science and policy advisor at ClientEarth, as The Guardian reported.

Last December, the status change was proposed by the European Commission at the Bern Convention on the Conservation of European Wildlife and Natural Habitats in preparation for amending the EU’s nature protection law, reported Euronews.

The downgraded status, which was welcomed by hunters, reduces the standards for shooting a wolf. The EU has said wolves kill 65,000 animals annually that were intended to be slaughtered for human consumption, The Guardian reported.

During the last two centuries, wolf populations were decimated across much of Europe. They recovered following habitat protections and regulations to reduce hunting, and it is estimated that there are now 20,000 wolves roaming the continent. The more robust numbers have led to increased conflict with farmers, who have called for culls in rural areas.

Animal rights activists said the move puts the wolf population — which once disappeared completely from France — at risk, reported AFP.

Sofie Ruysschaert, nature restoration policy officer with BirdLife Europe and Central Asia, said the downgrading of wolves’ protected status risked “undoing decades of European conservation progress,” as The Guardian reported.

There have been no documented killings of humans by wolves this century.

“The risk of downgrading this status is to weaken or even cause the decline of this species in Europe,” said Yann Laurans, head of WWF-France’s land biodiversity team, as reported by AFP.

Some have said the culling of wolves will not reduce attacks on livestock.

Nathan Horrenberger of the French Foundation for Biodiversity Research said the decision to lower protection for wolves in Europe is “not going to help solve the problems facing livestock farmers, because wolves have been shot in European countries for years… and it’s not bearing fruit.”

Horrenberger told AFP that killing wolves could actually disrupt pack behavior, creating “more solitary animals, who turn to easier prey, namely farm animals.”

Just five countries voted against the proposal, according to environmental association Green Impact, who referred to the decision as a “disgrace” and promised to bring it to European courts.

According to the commission, the status change will go into effect on March 7 of 2025, unless one-third of its members object.

Assessments by the Large Carnivore Initiative for Europe suggest that one wolf population is vulnerable and five are “near-threatened,” The Guardian reported.

Scientists overall have said the wolf population in Europe could survive the change, but also warn it could be fatal for local populations hovering near the survival threshold.

“Downgrading a species’ strict protection status for the political gain of a few, against scientific evidence, puts decades of conservation efforts at risk,” said Sabien Leemans, senior biodiversity policy officer with WWF’s European branch.

UN’s Top Court Begins Hearings on Landmark Climate Case

The International Court of Justice (ICJ) — the United Nations’ highest court — began hearings on Monday in the biggest case in its history. The hearings involve what legal obligations States have when it comes to climate change.

The proceedings represent efforts by the international community to formulate a legal framework to address the climate crisis.

“Climate change for us is not a distant threat,” Vishal Prasad, director of Pacific Islands Students Fighting Climate Change — a group active in bringing the legal action — told journalists before the hearings, as The Guardian reported. “It is reshaping our lives right now. Our islands are at risk. Our communities face disruptive change at a rate and scale that generations before us have not known.”

Vanuatu was the first country to present arguments at the hearings. The South Pacific nation of small islands urged the UN court to address the harms caused by climate change and the legal obligation of “a handful of readily identifiable states” to address their contributions to global heating and its impacts.

It is expected that a record amount of oral statements will be presented to the ICJ during the hearings, which will continue until December 13 in the Hague, Netherlands, reported UN News. 

Following the hearings, the ICJ will issue an advisory opinion — expected in 2025 — to clarify the legal obligations of States under international law, as well as the consequences for breaching those duties.

ICJ’s advisory opinions are not legally binding, but experts say they clarify law and are authoritative documents that will be referred to in future climate litigation, as well as during international climate negotiations, The Guardian said in another report.

Ralph Regenvanu, special climate change and environment envoy representing Vanuatu, told the ICJ judges that the “readily identifiable states” responsible for the climate crisis had produced most of the world’s greenhouse gas emissions while being the least affected by them.

The court heard testimony on how Vanuatu and other Pacific island states bear the brunt of more frequent and severe climate disasters, including rising sea levels.

“We find ourselves on the frontlines of a crisis we did not create,” Regenvanu said, as The Guardian reported.

The hearing was the result of diplomacy led by Vanuatu and years of work by Pacific island law students.

During the hearings, 98 countries will give statements, including wealthy nations most responsible for the climate crisis such as the United States, China, Russia and the United Kingdom.

Though the decision will not be legally binding, advisory opinions have “an authoritative value and cannot be neglected,” the ICJ Registrar said in a recent UN News interview.

UN Secretary-General António Guterres said the advisory opinion will assist the UN, General Assembly and Member States to “take the bolder and stronger climate action that our world so desperately needs,” as reported by UN News.

“It could also guide the actions and conduct of States in their relations with each other, as well as towards their own citizens. This is essential,” Guterres stressed.

Barbados Completes World’s First ‘Debt-for-Climate’ Swap

Barbados has secured the world’s first “debt-for-climate” swap to finance crucial water and sewage projects that will help the island cope with the destructive impacts of climate change.

Through a deal with international funding partners, the Caribbean island nation was able to replace outstanding debt with less expensive financing, which generated a savings of $125 million to be used to increase food security while enhancing water resources management, a press release from the European Investment Bank (EIB) said.

“In the face of the climate crisis, this groundbreaking transaction serves as a model for vulnerable states, delivering rapid adaptation benefits for Barbados. With upfront funding from our partners, we are building a state-of-the-art facility to boost water management, food security, and resilience — showcasing how innovation and cooperation drive environmental and fiscal gains,” Prime Minister Mia Mottley said in the press release.

Countries have been embracing more debt swaps in order to make investment funds available for nature conservation projects, Reuters reported.

The deal sets a climate adaptation financing benchmark, those involved said. It avoids the increasing public debt burden while helping to meet the nearly $360 billion annually the United Nations has said is necessary to assist developing nations with adapting to climate change.

Water availability in Barbados for farming and other activities is far below the global average.

Mottley’s Bridgetown Initiative calls for international financial institutions such as the World Bank to make ever increasing challenges like high debt levels, slower growth and climate change a priority.

Barbados plans to improve its water supply and security by building a New South Coast Water Reclamation and Reuse Facility to provide more than twice the available water by 2050. Additional funding will be put toward mangrove conservation, agricultural resilience and water restoration.

The Green Climate Fund (GCF) and Inter-American Development Bank gave $70 million in loans to start development. An additional grant of $40 million was also provided by GCF.

Through the deal, Barbados was able to buy back nearly $300 million in domestic bonds using a loan provided by Scotiabank of Barbados, RBC Royal Bank and CIBC Caribbean Bank. The loan includes sustainability performance targets which must be met or the government will be subject to financial penalties. The loan is backed by $150 million each from the Inter-American Development Bank and EIB.

“Barbados’ initiative enhances climate resilience and sets a benchmark for sustainable adaptation for the Caribbean. CIBC Caribbean is honored to again collaborate with the Government of Barbados and multilateral agencies like the IDB and EIB in setting precedents for innovative financial mechanisms that drive environmental stewardship in our region. This partnership underscores our commitment to accelerating climate action and fostering sustainable development across the Caribbean,” said Mark St. Hill, chief executive officer of CIBC Caribbean, in the press release.

Part of the European Union’s Global Gateway project, the guarantee from EIB is an attempt to attract countries from the Global South that have been relying on China’s Belt & Road Initiative for infrastructure funding.

“Debt-for-climate conversions can support responses to two overlapping crises: constraining debt and the escalating climate emergency. The Green Climate Fund is a proud partner of Barbados in bringing a coalition of financiers together, all backing an innovative financial instrument aimed at helping the island nation achieve its development and climate goals,” said Mafalda Duarte, executive director of GCF, in the press release.

COP16 to Address Global Land Degradation and Desertification Begins in Saudi Arabia

Following the recent United Nations biodiversity and climate conferences, the 16th Conference of the Parties (COP16) of the UN Convention to Combat Desertification (UNCCD) began Monday in Riyadh, Saudi Arabia, with the goal of tackling drought, desertification and land degradation.

The UN has found that, in order to restore the planet’s degraded lands and prevent desertification, an investment of at least $2.6 trillion will be needed by 2030.

“We depend on our land for survival. Yet, we treat it like dirt,” said UN Secretary-General António Guterres in a press release from UNCCD.

The 12-day summit seeks to respond to drought in the face of climate change while protecting and restoring the world’s lands. The most recent previous UNCCD meeting — in 2022 in the Ivory Coast — yielded a promise for “accelerating the restoration of one billion hectares of degraded land by 2030,” reported AFP.

“Even if the global geopolitical context overshadows these crucial meetings, this kind of astral conjunction may perhaps lead to concrete decisions,” said Mauro Centritto, a sustainable plant protection expert with Italy’s National Research Council who is representing civil society organizations from Western Europe in Riyadh, as Le Monde reported.

According to Centritto, it is time to “build synergies” to connect the three COP conferences, as global heating is likely to pass the threshold of 1.5 degrees Celsius above pre-industrial levels established in the 2015 Paris Agreement.

“If we don’t fight together against increasing droughts and advancing land degradation, we will never achieve the goals we have set ourselves to reduce greenhouse gas emissions and protect flora and fauna,” Centritto added.

At the COP16 gathering of 196 nations and the European Union, UNCCD said 1.5 billion hectares must now be restored by 2030 to combat escalating droughts and other crises, reported AFP.

One day prior to the COP16 conference in Saudi Arabia — a desert nation — a new UNCCD scientific report warned that degraded soils and forest loss were lowering resilience to biodiversity loss and climate change.

“If we fail to acknowledge the pivotal role of land and take appropriate action, the consequences will ripple through every aspect of life and extend well into the future,” Ibrahim Thiaw, UNCCD executive secretary, said in a press release from the World Meteorological Organization.

The degradation of Earth’s lands disrupts ecosystems while making the land less agriculturally productive, which leads to food shortages and migration.

Land is considered to be degraded when human activities such as deforestation or pollution harm its productivity. When degradation becomes extreme it leads to desertification.

“We are a desert country. We are exposed to the harshest mode of land degradation, which is desertification,” Osama Faqeeha, Saudi Arabia’s deputy environment minister, told AFP.

Saudi Arabia has a target of restoring 40 million hectares, including “several million hectares of land” by the end of the decade, Faqeeha said.

The country has recovered 240,000 hectares of land with methods like prohibiting illegal logging and the expansion of total national parks from less than 20 in 2016 to over 500, according to Faqeeha.

Lands can also be restored through crop rotation, tree planting, the restoration of wetlands and grazing management.

“We found ourselves caught in a vicious cycle that we must break,” Thiaw told the UNCCD conference, as AFP reported. “We can only achieve this if we move beyond the silos that hinder our collective action and if we adopt a holistic approach that recognizes the constant interaction between desertification, biodiversity loss, and the acceleration of climate change.”

Ocean Advocates Celebrate ‘Huge Win’ as Norway Pauses Deep-Sea Mining Plans

Norway agreed on Sunday to stop the first round of licensing for Arctic deep-sea mining following pressure from the Socialist Left Party (SV), reported The Guardian.

The small leftwing party refused to support the government’s budget if it did not halt deep-sea mining exploration licenses scheduled for next year.

“This puts a stop to the plans to start deep-sea mining until the end of the government’s term,” said SV party leader Kirsti Bergstø, as The Guardian reported.

The announcement came after over a year of pressure from scientists, environmental activists and the international community, a press release from Greenpeace said.

🚨 HUGE WIN – Norway agreed to stop deep sea mining in the Arctic This is a win for global mobilisation and a huge step forward to protect the Arctic This fragile ecosystem is safe from deep sea mining at least until the end of 2025 – and we won’t stop there #StopDeepSeaMining

“This is a huge win! After hard work from activists, environmentalists, scientists and fishermen, we have secured a historic win for ocean protection, as the opening process for deep sea mining in Norway has been stopped. The wave of protests against deep sea mining is growing. We will not let this industry destroy the unique life in the deep sea, not in the Arctic nor anywhere else,” said deep-sea mining campaigner Haldis Tjeldflaat Helle with Greenpeace Nordic, in the press release.

At the beginning of 2024, Norway became the first nation to approve commercial deep-sea mining.

According to the country’s coalition government, preparatory work — such as setting regulations and conducting environmental impact assessments — would continue while the licenses were suspended, reported The Guardian.

“This will be a postponement,” Prime Minister of Norway Jonas Gahr Støre, a member of the Labour party, told private broadcaster TV2.

Norway is being sued by WWF over its plans to allow companies to mine an area of more than 100,000 square miles for deep-sea minerals without taking proper measures to adequately investigate the consequences.

The Norwegian Environment Agency said the impact assessment did not provide a sufficient legal or scientific basis for deep-sea mining.

A worldwide moratorium on deep-sea mining has been called for by over 900 ocean scientists.

Earlier this year, Europe’s parliament expressed concern over Norway’s decision to allow the destructive activities and called on Norwegian member states to back a moratorium.

“There will be no announcement of exploration rights for deep-sea mining in 2024 or 2025,” SV said in a statement, as AFP reported.

Norway’s government said a study confirmed that a substantial store of minerals and metals — including copper and rare earth elements — were discovered on its continental shelf. These metals are necessary for the transition away from fossil fuels, it argued.

A 32-member coalition, including France, Brazil, the United Kingdom, Canada and Germany, has called for a deep-sea mining moratorium in international waters.

“Millions of people across the world are calling on governments to resist the dire threat of deep sea mining to safeguard oceans worldwide. This is a huge step forward to protect the Arctic, and now it is time for Norway to join over 30 nations calling for a moratorium and be a true ocean champion,” said Louisa Casson, campaigner for Greenpeace International Stop Deep Sea Mining, in the press release.

Deep-sea mining is devastating to marine ecosystems, producing toxic sediment plumes that choke the unique sea life that lives on the bottom of the ocean floor while creating disruptive noise pollution and turning the seabed into a barren wasteland.

“Stopping the Norwegian deep sea mining plans is an important step in stopping this industry from destroying life at the bottom of the sea. Any government that is committed to sustainable ocean management cannot support deep sea mining. It has been truly embarrassing to watch Norway positioning itself as an ocean leader, while planning to give green light to ocean destruction in its own waters,” Helle said in the press release.

World Leaders Fail to Reach Agreement on Global Plastics Treaty, Plan to Continue Talks

Efforts by nations to come to an agreement on a global plastics treaty failed on Monday. While more than 100 countries sought to put a limit on the world’s plastics production — in addition to tackling recycling and cleanupoil and gas companies were only prepared to address the problem of plastic waste.

The meeting in Busan, South Korea was supposed to be the last, but negotiations will continue into 2025, reported The Associated Press.

“It is clear that there is still persisting divergence,” said Inger Andersen, the United Nations Environment Programme’s executive director, as Reuters reported.

The fifth meeting of the UN Intergovernmental Negotiating Committee (INC-5) ended with countries still far from establishing the fundamental scope of a global plastics treaty.

Putting a cap on plastic production, the management of “chemicals of concern” used in the plastics making process and plastic products, as well as financing for developing countries in implementing the treaty were the most divisive issues during negotiations.

Panama proposed a path to a worldwide plastic production reduction target, which was supported by more than 100 nations, while an entirely different proposal had no provisions for a cap on production.

According to a Center for International Environmental Law (CIEL) analysis, more than 200 representatives of the chemical and fossil fuel industry attended the talks — the largest group of delegates at the meeting, reported The Guardian.

Sixteen plastics industry lobbyists were present in the delegations from China, Iran, Kazakhstan, Malaysia, Egypt, Finland and the Dominican Republic.

A draft revised document released Sunday by Luis Vayas Valdivieso, chair of the meeting, could be the foundation for a treaty, but still included multiple options on the most contentious issues, reported Reuters.

“A treaty that… only relies on voluntary measures would not be acceptable,” said Juliet Kabera, Rwandan Environment Management Authority director general. “It is time we take it seriously and negotiate a treaty that is fit for purpose and not built to fail.”

Saudi Arabia and other oil-producing nations expressed strong opposition to the reduction of plastics production and attempted to delay negotiations with procedural tactics.

“There was never any consensus,” said Al Gwaiz, delegate from Saudi Arabia. “There are a couple of articles that somehow seem to make it (into the document) despite our continued insistence that they are not within the scope.”

According to dataset manager Eunomia, the United States, China, India, Saudi Arabia and South Korea were 2023’s five biggest producers of polymers.

If a treaty could have been established at INC-5, it would have been among the most important environmental protection deals since the Paris Agreement.

During the talks, the U.S., which had expressed support for voluntary production reductions, was accused of not using its sway to press for legally binding actions.

“Despite maintaining in the lead-up to and during the INC that production and chemicals were important measures for the treaty, they refused to… answer the call to join more than 100 countries calling for legally binding measures,” said Rachel Radvany, campaigner for environmental law group CIEL, as reported by The Guardian.

A 2023 report from the UN Environment Programme found more than 3,200 plastic chemicals of concern, which are especially toxic for women and children, Reuters reported.

Plastic production worldwide is on course to triple by mid-century. 

Several negotiators participating in the talks expressed an urgent desire to resume the talks.

“Every day of delay is a day against humanity. Postponing negotiations does not postpone the crisis,” said Juan Carlos Monterrey Gomez, head of Panama’s delegation, as reported by Reuters. “When we reconvene, the stakes will be higher.”

Air Fryers Offer Least Polluting Cooking Method, Researchers Find

If you’re looking to keep your indoor air cleaner over the holidays, a new study has found that air fryers emit just a small portion of the indoor air pollutants produced by other cooking methods like pan and deep frying.

Most people spend most of their time — 80 percent — indoors, and cooking is a big contributor to indoor air pollution. The energy efficiency of air fryers has been amply studied, but less is known about their environmental benefits, a press release from England’s University of Birmingham said.

“As expected, oil-based cooking methods produced much more [particulate matter (PM)] and [volatile organic compounds (VOCs)] in the indoor environment than water-based methods,” the authors wrote in the study. “The air fryer generated the least PM emissions.”

Indoor pollutants are a significant health concern and can cause a range of symptoms and chronic conditions like respiratory, cardiovascular and neurodegenerative diseases.

As their test kitchen, the scientists used a well-controlled campus research kitchen as a compromise between experiments measuring pollution produced by various cooking methods conducted in a laboratory, and testing in the less regulated environment of a domestic kitchen.

For the experiments, the researchers used five different methods to prepare chicken breast: pan frying, deep-fat frying, stir-frying, boiling and air-frying. They then measured the levels of VOCs and PM emitted by each cooking method.

For PM, the research team used micrograms for each cubic meter of air to measure peak concentrations. The peak concentration for pan frying was 92.9, deep frying measured 7.7, stir-frying had a peak concentration of 26.7, boiling came in at 0.7 and air-frying 0.6.

The measurements for VOCs were “parts per billion,” or ppb. Pollution levels were relatively similar to the PM emissions across the variety of cooking methods. The team also identified and quantified certain VOCs emitted most during each activity.

“There are a number of factors that will affect the levels of pollution from cooking alongside the method used, including the amount of oil used, and the temperature of the stove. What we can say with certainty, however, is that improving the ventilation in kitchens by opening windows or using extractor fans, will help to disperse polluting particles and reduce personal exposure,” said lead author of the study Christian Pfrang, a professor of atmospheric science at University of Birmingham, in the press release.

The team kept measuring the pollution emitted for both VOCs and PM following the conclusion of the cooking process. They found that substantially higher pollution levels remained in the kitchen for more than an hour after cooking, even though the preparation only took about 10 minutes.

“It’s also really important to understand that particles will remain in the air for quite some time after you have finished cooking, so continuing to ventilate, or keeping extractor fans turned on for a period of time will really help to avoid the build-up of this indoor pollution and reduce the potential for the pollutants to be transported and distributed throughout the house with the associated higher personal exposures,” Pfrang added.

The study, “Impact of Cooking Methods on Indoor Air Quality: A Comparative Study of Particulate Matter (PM) and Volatile Organic Compound (VOC) Emissions,” was published in the journal Indoor Air.

44% of Experts Surveyed Believe China’s CO2 Emissions Have Already Peaked or Will Peak Next Year

Nearly half of climate experts — 44 percent — believe China’s carbon dioxide emissions may have already peaked, or will peak in 2025 at the latest, according to a new report from think tank Centre for Research on Energy and Clean Air (CREA).

China’s carbon emissions are also on track to increase slightly this year, despite fast progress on electric vehicles (EVs) and renewables.

The third edition of the annual report, China’s Climate Transition: Outlook 2024, indicated increasing optimism about China’s green transition, reported The Guardian.

“Clean energy industries have emerged as key drivers of economic growth. As China continues its transition, the benefits are becoming increasingly clear,” said Shi Xunpeng, one of the authors of the report and the president of the International Society for Energy Transition Studies, as The Guardian reported.

The 44 experts from industry and academia surveyed for this year’s report were much more optimistic about China’s carbon emissions peaking by next year than they were during last year’s survey, when just 21 percent had the same opinion.

In the report, CREA reassessed China’s progress toward its climate and emissions commitments aligned with the goals of the Paris Agreement, a press release from CREA said.

In response to the question of whether they believed coal consumption in China had peaked, 36 percent of the experts surveyed said yes, compared with 15 percent in 2023. Fifty-two percent of the experts expect the country’s consumption of coal to peak by next year, with just 20 percent saying the peak will occur later.

Coal currently makes up 80 percent of fossil fuel emissions in China, reported The Guardian.

China has set a target of reaching peak carbon emissions by the end of the decade and overall carbon neutrality by 2060. A pledge from Beijing to “strictly control” coal use in the country’s 14th “five-year plan” covers the period up until the end of next year.

“China already plans to reduce its coal consumption after 2026 but this cut will definitely have to be pretty drastic and fast if China wants to achieve the 2060 carbon neutrality goal,” said Wang Xiaojun, founder of Manila-based NGO People of Asia for Climate Solutions, as The Guardian reported.

Over the last two years, China has been focusing on renewables industries to rebuild its post-pandemic economy by developing EVs, batteries and solar panels, which have attracted high levels of investment.

The analysts included in the study also looked at whether China can lower its economy’s carbon intensity — or how much carbon dioxide is released in the production of one unit of electricity.

“In order to align with the Paris agreement… China will need to either speed up renewable energy deployment even further or guide economic development in a less energy-intensive direction,” said lead analyst at CREA Lauri Myllyvirta, as reported by The Guardian.

Safeguarding Natural Areas Can Protect Cities From Flooding, Canadian Study Finds

All over the world, floods have been increasing in frequency and intensity due to climate change.

A new study led by researchers at University of British Columbia (UBC) shows that protecting key ecosystems across Canada could reduce the risk of flooding in over half of urban areas in the country that are at high risk.

The study presents a global roadmap for the integration of nature-based solutions into flood management and urban planning, a press release from UBC said.

“This is the first national study to assess the role of Canadian ecosystems in flood prevention and to identify where conservation could have the greatest impact,” said Dr. Matthew Mitchell, an assistant professor of forestry and land and food systems at UBC, in the press release.

The research demonstrates that protecting the most essential five percent of watersheds, which equates to roughly two percent of Canada’s total land — 201,000 square kilometers — can greatly reduce the amount of rainwater runoff, protect croplands and safeguard homes and livelihoods.

Upstream watersheds near cities like Toronto and Vancouver play a major role in the protection of 3.7 million people who live in floodplains, as well as another 20.1 million residents nearby — over half the country’s population.

The research team used global data to analyze how land types such as wetlands, forests and riparian zones reduce runoff and absorb water.

These natural systems improve water quality, support wildlife and prevent downstream flooding, while lowering the reliance on dams and other destructive and costly infrastructure.

“Nature-based solutions are highly effective for managing flood risks, and this study shows exactly where conservation can make the biggest impact,” Mitchell said in the press release.

The researchers identified British Columbia (BC) ecosystems that are vital for flood prevention, including alpine and subalpine ecosystems that help prevent downstream flooding and regulate water flow in the Columbia and Coast Mountains; wetlands and forests in the Similkameen and Okanagan Valleys, which safeguard important agricultural areas and expanding population centers; and Fraser River Delta wetlands — including peatlands like Burns Bog — which are essential for Lower Mainland flood protection.

Outside of BC, in the prairie provinces of Manitoba, Alberta and Saskatchewan, the research team recommended the protection of grasslands and wetlands in important river watersheds like the Saskatchewan and Red Rivers.

In the Northern Regions, they suggested prioritizing the conservation of wetlands and ecosystems in areas such as the Northwest and Yukon Territories.

In Southern Ontario, the team recommended safeguarding Great Lakes wetlands and major rivers in cities like Ottawa, Hamilton and Toronto to reduce flood risks.

Canada has promised to protect 30 percent of its lands by 2030, but just eight percent of the country’s ecosystems that are most crucial for flood protection are currently being preserved. The research team called for more funding and stronger conservation policies to make these high-impact areas a priority.

“This research makes it clear that conserving nature isn’t just about biodiversity—it’s also about protecting communities and making cities more resilient to climate change,” Mitchell said.

The study, “Flood prevention benefits provided by Canadian natural ecosystems,” was published in the journal Ecosystem Services.
