How to Slow Global Warming: Three Widescale Efforts Could Make the Difference
PNNL News Release:
As COP28 and a potential temperature overshoot loom on the horizon, scientists point to three major efforts that could curb global warming
September 29, 2023 |
RICHLAND, Wash.—With the 2023 United Nations Climate Change Conference just nine weeks away, countries will soon take stock of their progress in the worldwide effort to slow and adapt to global warming. Better known as COP28, the conference offers the chance for countries to meet and coordinate their climate-mitigating pledges, like achieving carbon neutrality by 2050 or peak emissions by 2030.
Past research suggests that, if current pledges are upheld, the world is roughly enroute to keep warming below 2 degrees Celsius. But the original goal of the Paris Agreement—the 2015 climate change treaty in which 196 countries aspired to cap global warming at 1.5 degrees by the end of this century—remains stubbornly out of reach.
“There’s the bad news,” said Haewon McJeon, visiting professor at the Korea Advanced Institute of Science & Technology, whose research often focuses on assessing climate pledges. “We took stock of the current climate pledges around the world, and it all falls far short of the 1.5-degree goal. It’s not enough.”
What can countries do to bring the goal back within reach? In a new commentary published in the journal One Earth, researchers highlight that the biggest climate mitigation gains stand to be realized through three global efforts: reigning in non-CO2 emissions like methane and fluorinated gasses, ramping up carbon dioxide removal, and halting deforestation. Make sufficient progress in these areas, the authors said, and the 1.5-degree goal may inch back within our crosshairs.
"Mitigating emissions from all sources will be critical to limiting warming to less than 1.5 degrees Celsius," said Gokul Iyer, lead author on the commentary and an Earth scientist at the Department of Energy’s Pacific Northwest National Laboratory. "While most efforts to date have focused on carbon dioxide emissions in the energy sector, those three areas present opportunities for further ratcheting of ambition."
An opportunity to adjust course is fast approaching. The Paris Agreement holds a built-in “ratcheting” mechanism, a course-correcting process where countries can regularly revise their climate pledges in five-year increments.
Its purpose is to bring about more bold and ambitious action within the push to curb warming. COP28 marks the first time participating countries will undergo this “progress review,” known as the Global Stocktake, which stands to shape the adjusted pledges.
Ratchet up ambition to dial down emissions: Beyond carbon dioxideCarbon dioxide is the most well-known greenhouse gas, yet it is one of several. Though less prevalent, other gasses like methane and nitrous oxide can trap even more heat. The latter can linger in Earth’s troposphere for well over a century before moving to the stratosphere where it chips away at the ozone layer.
Dialing down nitrous oxide and other non-CO2 emissions sooner rather than later, the authors said, could help curb peak warming this century.
“Doing so could ‘flatten the curve’ of a temperature overshoot, where global temperatures exceed 1.5 degrees and eventually cool back down,” said Yang Ou, a coauthor on the study and researcher at the College of Environmental Sciences and Engineering at Peking University.
Some progress here has already been made, notably the Global Methane Pledge, in which over 150 countries voluntarily pledged to reduce methane emissions. Yet more detailed actions are needed, the authors said.
Fortunately, many of the technologies needed to reduce non-CO2 emissions already exist. Substituting climate-friendly cooling agents, detecting and repairing natural gas leaks, and recovering refrigerants when disposing of air conditioning or refrigeration equipment all could help in diminishing those emissions. Widespread dietary changes, like eating less meat, could also help dial down emissions within the agricultural sector.
Still, the authors said, more progress is needed. Countries could address a wider range of non-CO2 emissions. Currently, methane takes a large focus, whereas nitrous oxide and fluorinated gasses are equally if not more important, according to the new work.
And as new mitigation measures around these long-unaddressed emissions come into existence, countries could benefit from considering all sectors and sources from which they flow, from livestock to energy production.
Ramping up carbon dioxide removalRemoving carbon dioxide from Earth’s atmosphere is essential, the authors said. They highlight an important gap between the amount of carbon dioxide countries have pledged to remove versus the amount that must be removed to meet the goals of the Paris Agreement.
Current pledges are insufficient, according to the authors; we must pull an additional 1–3 gigatons of carbon dioxide from Earth’s atmosphere annually by 2030, and 2–7 gigatons annually by 2050. Otherwise, the 1.5-degree goal will likely remain out of reach.
Many carbon dioxide removal technologies remain nascent and expensive. Yet, to meet the warming goal, they must be made cost effective and deployed at wide scales. The next decade, the authors said, is key.
They call for incentives to drum up research, development, demonstration, and the deployment of novel and alternative carbon dioxide removal methods. A wide-ranging approach to carbon removal offers the surest course, from afforestation and reforestation to the use of biofuels paired with carbon capture and storage.
The authors note some progress: investments in carbon dioxide removal technology have swelled in recent years, totaling $4 billion in publicly funded research. Yet only a few countries have made such investments, which have mostly focused on a limited number of removal methods.
“More widespread participation could ultimately drive down costs,” said McJeon, also a coauthor of the new commentary. “And it could demonstrate an important point: that carbon dioxide removal can be carried out around the world in a variety of ways, as each region is better suited for some removal methods over others.”
Halting deforestationThe authors of the new commentary point to 4.1 million hectares of tropical forest lost to deforestation in 2022 alone. A significant chunk of global emissions—16 percent—flowed from deforestation and other forms of land use change between 2012 and 2021. In some regions, forests that were once carbon sinks have turned into sources. What could greater ambition in this area look like?
The authors suggest several courses of action. Putting caps on climbing deforestation rates could help. Ceasing or reducing consumption of products like palm oil or soy, too, could protect forests in important regions like South America.
Better monitoring of illegal mining and hunting, creating new incentives to protect fire-prone forests from severe wildfire, and financing commitments to protect forests are all examples of worthwhile efforts, the authors said.
The team pays kudos to the European Union, the United Kingdom and Brazil, whose governments recently reported significant declines in deforestation rates since July 2022. The Forests and Climate Leaders' Partnership—a joint declaration to halt and reverse forest loss and land degradation by 2030—was signed by over 100 countries at COP27. If we are to meet the warming goal, however, similar progress must be made at a wider scale, according to the authors.
"While the upcoming global stocktake process will likely focus on assessing climate actions and progress made to date,” said Iyer, “it will be important to focus negotiations and discussions on initiatives to ratchet ambition in hitherto ignored areas. Progress in those areas could greatly shape the trajectory of global emissions in the coming decades and improve our chances of staying below 1.5 degrees Celsius."

EPA Cleanup Plan Will Address Contaminated Soil at the Olean Well Field Superfund Site in Cattaraugus County, New York
EPA Press Office:
EPA Cleanup Plan Will Address Contaminated Soil at the Olean Well Field Superfund Site in Cattaraugus County, New York
NEW YORK (September 29, 2023) – The U.S. Environmental Protection Agency (EPA) has finalized its cleanup plan to excavate and remove soil contaminated with volatile organic compounds on the former AVX Corporation (AVX) property at the Olean Well Field Superfund site in Olean, New York. This action will protect those at risk and remove a source of groundwater contamination.
“Following a public meeting, and the opportunity to hear directly from the community, EPA has finalized its cleanup plan for the Olean Well Field Superfund site,” said Regional Administrator Lisa F. Garcia. “This plan will enable us to remove soil that is a source of contamination at this site and advance our over overall cleanup of the site.”
The finalized plan will address soil contamination that was not fully addressed by prior cleanup actions. The contamination is under and near the former manufacturing building on the AVX Property. Under the plan, contractors will:
- demolish and remove the concrete slab floor and foundation.
- dig out the polluted soil that is above the water table.
- take the dug-out material off site.
- restore the area with clean fill.
The Olean Well Field site is an approximately 1.5 square-mile area in Cattaraugus County that contains various wells, homes, and manufacturing facilities. Earlier industrial operations at the AVX property, as well as at three other facilities that EPA considers sources of site contamination, resulted in the contamination of soil and groundwater with trichloroethylene, 1,4-dioxane, and other volatile organic compounds. As a result of the contamination at all four facilities, EPA added the site to the Superfund list in 1983. Since that time, several investigations have led to cleanup remedies for the four source facilities impacting soil and groundwater, most of which are being carried out by parties responsible for the site.
On July 27, 2023, EPA proposed this cleanup plan to the public and held a public meeting on August 8, 2023, to explain the plan and take comments. The finalized plan, called a Record of Decision, released today, addresses the comments received and formalizes EPA’s selected cleanup plan for the contaminated soil at the site.

EPA Further Extends Comment Period for Proposed Cleanup of Contaminated Sediment at Quanta Resources Superfund Site in Edgewater, NJ
EPA Press Office:
EPA Further Extends Comment Period for Proposed Cleanup of Contaminated Sediment at Quanta Resources Superfund Site in Edgewater, NJ
NEW YORK (Sept. 29, 2023) - The U.S. Environmental Protection Agency (EPA) has extended the public comment period for its proposed cleanup plan to address contaminated sediment and surface water at the Quanta Resources Superfund site in Edgewater, New Jersey to November 6, 2023. The original public comment period was scheduled to end on October 6, 2023. EPA previously held a public meeting at the Edgewater Community Center on July 25, 2023, to explain the new cleanup proposal to the public.
The cleanup outlined in the proposed plan will address the sediment and surface water contamination in an area of the site called Operable Unit 2 (OU2). Sediment in OU2 is contaminated with polycyclic aromatic hydrocarbons (PAHs), highly concentrated tar-like material referred to as non-aqueous phase liquid (NAPL), and arsenic. Under the proposed plan, EPA would oversee work to:
- Demolish the 115 River Road pier structure and remove other pilings and structures within the contaminated area, to access and remove contaminated sediment underlying the pier structure.
- Remove contaminated sediment to depths ranging from 10 to 30 feet and take it to a licensed facility off-site for disposal.
- Place a cap over less contaminated areas of the river bottom to lock in residual contamination.
- Establish “institutional” controls such as navigational restrictions, signs prohibiting swimming, wading, or fishing, and other use restrictions to protect the cap.
- Monitor sediment and surface water long-term to assess the effectiveness of the cleanup in preventing the migration of contaminants from sediment to surface water and maintaining the cap as needed.
Written comments on the proposed plan may be mailed or emailed by November 6, 2023, to Thomas Dobinson, Remedial Project Manager, U.S. Environmental Protection Agency, 290 Broadway – 19th Floor, New York, NY 10007, Email: Dobinson.Thomas@epa.gov.

EPA Finalizes Rule to Require Reporting of PFAS Data to Better Protect Communities from Forever Chemicals
EPA Press Office:
EPA Finalizes Rule to Require Reporting of PFAS Data to Better Protect Communities from Forever Chemicals
WASHINGTON (Sept. 28, 2023) – Today, the U.S. Environmental Protection Agency (EPA) finalized a rule that will provide EPA, its partners, and the public with the largest-ever dataset of per- and polyfluoroalkyl substances (PFAS) manufactured and used in the United States. This rule builds on over two years of progress on the Biden-Harris Administration’s action plan to combat PFAS pollution, safeguarding public health and advancing environmental justice, and is a key action in EPA’s PFAS Strategic Roadmap.
PFAS are a category of manufactured chemicals that have been used in industry and consumer products since the 1940s. PFAS have characteristics that make them useful in a variety of products, including nonstick cookware, waterproof clothing, and firefighting foam, as well as in certain manufacturing processes.
The reporting rule under the Toxic Substances Control Act (TSCA) is a statutory requirement under the FY2020 National Defense Authorization Act (NDAA) that requires all manufacturers (including importers) of PFAS and PFAS-containing articles in any year since 2011 to report information related to chemical identity, uses, volumes made and processed, byproducts, environmental and health effects, worker exposure, and disposal to EPA.
“The data we’ll receive from this rule will be a game-changer in advancing our ability to understand and effectively protect people from PFAS,” said Assistant Administrator for the Office of Chemical Safety and Pollution Prevention Michal Freedhoff. “Today we take another important step under EPA’s PFAS Strategic Roadmap to deliver on President Biden’s clear direction to finally address this legacy pollution endangering people across America.”
In order to effectively research, monitor, and regulate PFAS, EPA is taking action to better understand who is using PFAS, how they are being used, and in what quantities. This rule will produce actionable data that can be used by EPA, as well as state, local, and Tribal governments to craft policies and laws that protect people from dangerous “forever chemicals.”
Since EPA proposed this rule in June 2021, the agency has provided multiple opportunities for public comment and stakeholder input, including a Small Business Advocacy Review Panel in April 2022 and an Initial Regulatory Flexibility Analysis released for public comment in November 2022.
The final rule expands on the definition of PFAS in the proposed rule to include 41 additional PFAS that were identified as being of concern. EPA has determined that at least 1,462 PFAS that are known to have been made or used in the U.S. since 2011 will be subject to the final rule, better capturing the important data the agency needs to protect human health and the environment from these chemicals.
The final rule also streamlines reporting requirements and reduces the burden for those who made or used small quantities of PFAS for research and development purposes and for those who imported PFAS contained in articles into the U.S.
Data is due to EPA within 18 months of the effective date of the final rule, with an additional six months for reports from small businesses that are solely reporting data on importing PFAS contained in articles.
It’s Official: Air Across New Jersey Meets National Standards for Sulfur Dioxide

It’s Official: Air Across New Jersey Meets National Standards for Sulfur Dioxide
Final Designation of Warren County as Meeting the Standard Highlights Success of Decades of Air Pollution Regulation
NEW YORK (September 28, 2023) – The Environmental Protection Agency (EPA) announced today that it has approved the State of New Jersey’s request to redesignate Warren County, New Jersey as being “in attainment” with national health-based outdoor air quality standard for sulfur dioxide (SO2). For the first time since 1987, all of NJ is now designated as meeting the SO2 standard.
“This was a long time coming and is a testament to the collaborative efforts of state and federal agencies, as well as the commitment of industry stakeholders, in achieving cleaner air for the residents of Warren County, New Jersey,” said EPA Regional Administrator Lisa F. Garcia. “Air quality continues to improve across New Jersey, and it is great that we can deliver cleaner air to future generations of New Jerseyans.”
“This action is indeed a reflection of the longstanding commitment by New Jersey to hold out-of-state sources of air pollution, including coal fired power plants, accountable for impacts to downwind states,” said New Jersey Commissioner of Environmental Protection Shawn M. LaTourette. “The Murphy Administration thanks the U.S. Environmental Protection Agency for working collaboratively with us to improve air quality for all of New Jersey’s residents.”
In December 1987, EPA had designated portions of Warren County, New Jersey as nonattainment with SO2 air quality standards. The Warren County Nonattainment Area included the entire Townships of Harmony, Oxford, White, and Belvidere, and portions of Liberty and Mansfield Townships.
The initial nonattainment designation was primarily attributed to air pollution from large, upwind sources in Pennsylvania, including the Martins Creek and Portland Generating plants. Since that time, coal-fired units at these facilities have been permanently shut down, and oil-fired units no longer use high-sulfur fuels, which has dramatically cut SO2 emissions New Jersey has also implemented stringent measures, requiring the use of ultra-low sulfur diesel, further contributing to the area's improved air quality.
The Clean Air Act identifies two types of national ambient air quality standards for several key pollutants, among them SO2. Primary standards provide public health protection, including protecting the health of "sensitive" populations such as asthmatics, children, and the elderly. Secondary standards provide public welfare protection, including protection against decreased visibility and damage to animals, crops, vegetation, and buildings. Periodically, the standards are reviewed and sometimes revised, establishing new standards. NJ is still working to meet increasingly more stringent standards for the ozone, but the air quality trend in NJ for all measured pollutants is downward.
