Climate and Clean Air Coalition leaders: We must significantly reduce short-lived climate pollutants by 2030

A meeting of ministers and high-level representatives of the Climate and Clean Air Coalition (CCAC) agreed to accelerate efforts to significantly reduce short-lived climate pollutants by the end of the next decade in order to put the world on a “pathway that rapidly reduces warming in the near term and maximizes development, health, environmental, and food security benefits”. These efforts, they noted, must be complementary to aggressive carbon dioxide mitigation and a transition to a zero-carbon economy by mid-century.

Meeting a day before the United Nations Secretary-General’s Climate Action Summit, the Coalition’s High-Level Assembly put forward a 2030 Vision Statement that aims to ensure the earth’s atmosphere continues to enable people and the planet to thrive by limiting warming to 1.5˚ Celsius and drastically reducing air pollution.

In a message to the Assembly, Finnish President Sauli Niinistö reiterated the urgency required: “Climate change impacts the Arctic faster than any other region in the world. Reducing black carbon emissions is the most immediate way to limit further damage. As a partner of the Climate and Clean Air Coalition Finland is committed to this work on a global scale. Because this is not just a regional emergency. If we lose the Arctic, we lose the globe.”

Short-lived climate pollutants like methane, black carbon and hydrofluorocarbons (HFCs) – also known as super pollutants – are many times more powerful than carbon dioxide at warming the planet but because they are short-lived in the atmosphere, preventing emissions can rapidly reduce the rate of warming. Many are also dangerous air pollutants and reductions will benefit human health and ecosystems.

The Coalition’s goal is to reduce short-lived climate pollutants beyond the recommendations made by the Intergovernmental Panel on Climate Change (IPCC) in its special report Global Warming of 1.5˚C.

Increasing action on short-lived climate pollutants can avoid an estimated 2.4 million premature deaths from outdoor air pollution annually by 2030, prevent as much as 52 million tonnes of crop losses per year, and slow the increase in global warming by as much as 0.6°C by 2050. It can also prevent the climate tipping points that can exacerbate long-term climate impacts and make adapting to climate change harder, especially for the poor and most vulnerable.

Inger Andersen, Executive Director of the United Nations Environment Programme (UNEP), which hosts the CCAC’s Secretariat, said the Coalition was tackling two of the world’s most serious threats – air pollution and the climate crisis – at the same time.

“We need to urgently tackle climate change and keep temperatures from exceeding dangerous thresholds. Reducing short-lived climate pollutants is an essential ingredient of our strategy,” she said. “Polluted air is killing millions of people around the globe prematurely and severely impacting their quality of life. The CCAC is addressing these two issues together. Action on either front contributes to the goals of the other.”

The benefits of integrating efforts on climate change and air quality by taking a whole-of-government approach was reiterated by Xie Zhenhua, China’s Special Representative for Climate Change, as he launched a new report by the United Nations Environment Programme (UNEP), Tsinghua University and the CCAC called Synergizing Action on the Environment and Climate Change. The report shows how policies that address both air pollution and climate change can effectively rally national, local and societal support for a low-carbon climate strategy because people can see immediate benefits to air quality, urban infrastructure and clean energy development.

“By killing multiple birds with one stone, co-governance of the climate, environment and development is cost-effective and achieves greater economic, social, environmental and climate benefits. It works in China, and I am sure it will work in other countries,” Mr. Xie said.

As the world warms, demand for refrigeration and cooling will soar. The Coalition launched its Efficient Cooling Initiative this year to ensure that as the world phases down HFCs that replacement cooling technology is also highly energy efficient.

Oil and gas production and distribution is another large source of methane and black carbon – a climate problem that can be solved this decade. Fred Krupp, President of the Environmental Defense Fund, called on gas producing and consuming countries to commit to action and reduction targets of 45 percent by 2025 and 60 percent to 75 percent by 2030, or to a near-zero methane intensity target for new developments.

“These targets are realistic and achievable, especially in a sector where technology and financing are largely available, and innovation supports even larger reductions,” Mr. Krupp said. “Every oil and gas producing and consuming country can act and benefit. Countries’ Nationally Determined Contributions need to become explicit about oil and gas methane emissions.”

Closing the meeting, Carolina Schmidt, Chile’s Minister of Environment and COP25 President-Designate, said that the science shows that the world needs to work on both non-carbon pollutants and greenhouse gases to ensure the world prevents climate change.

“We must put people first when it comes to climate change. Climate action is not about cost it is about opportunities to make a better life. In Chile, we know there is a strong link between air pollution and climate action. Santiago currently has the second-largest fleet of electric buses in the world after China and people are celebrating this by choosing electric buses over all other transport systems,” Ms. Schmidt said. “We wait for all of you in Chile because now it is time for action.”
