Driving Global Action on Climate Change

Bloomberg Philanthropies’ Environment program tackles one of the world’s greatest challenges: the climate crisis. With government and business leaders, experts, and grassroots advocates, we are taking bold action to build a more sustainable economy.

Driving the U.S. Transition Away from Fossil Fuels

Bloomberg Philanthropies has long been at the forefront of the U.S. fight to end coal and accelerate the transition to clean energy, beginning with our partnership with the Sierra Club on the grassroots Beyond Coal campaign in 2011. In 2019, building on that campaign’s success, we launched Beyond Carbon to retire all remaining U.S. coal plants by 2030, block proposed methane gas plants, and support states and climate leaders to pass strong clean energy policies. In 2022 alone, through grassroots pressure, litigation, advocacy, and other strategies, the program secured retirements of 17 coal plants, blocked 34 new gas plants, and helped three states pass 100% clean energy or net-zero emissions policies. In the decade between 2010 and 2020, this work delivered more than 80% of all the progress the United States has made in reducing greenhouse gas emissions.

In 2022, Bloomberg Philanthropies launched a new campaign to block the construction or expansion of new U.S. petrochemical facilities, a major source of carbon emissions, air pollution, and cancer-causing toxins. Petrochemicals are a broad group of chemicals that are derived from gas and oil and used to make plastics and fertilizers. Our Beyond Petrochemicals campaign aims to block roughly 120 proposed facilities that would produce petrochemicals, concentrated in five states: Texas, Louisiana, Pennsylvania, Ohio, and West Virginia. Existing facilities already meet the current demand for petrochemicals, and these planned facilities threaten to subject local communities to even greater health and climate risks.

Beyond Petrochemicals

In September 2022, our partners used litigation and grassroots organizing to block the massive Formosa petrochemical plant, which was proposed along the Mississippi River between New Orleans and Baton Rouge, Louisiana. The plant would have released carbon emissions equivalent to three coal plants, along with other toxic pollutants.

Accelerating the Global Clean Energy Transition

Beginning in 2017 with the launch of the Europe Beyond Coal campaign, Bloomberg Philanthropies has worked to end coal and accelerate clean energy investment globally. In Europe, this work has retired more than 52% of the continent’s coal plants. Similar campaigns have secured the early retirement of one-third of Australia’s plants and one-third of South Korea’s plants, and canceled more than half of Japan’s planned plants. We have also supported additional research, advocacy, and technical assistance in China, India, and Indonesia to help lay out a path for the clean energy transition. In 2022, we expanded this work to 25 developing countries across Africa, Southeast Asia, and South America with the greatest threat of new coal and the greatest potential for clean energy development.

Bloomberg Philanthropies also leads and supports a wide array of efforts to mobilize the private sector in the global climate fight. Mike chairs the Task Force on Climate-related Financial Disclosures (TCFD), which shares guidelines to help companies quantify and disclose risks posed by climate change, bringing greater transparency to the financial impacts of the climate crisis. He also co-chairs the Glasgow Financial Alliance for Net Zero (GFANZ) with Bloomberg Philanthropies board member Mark Carney, which helps financial institutions and other private-sector organizations commit to reaching net-zero emissions, create credible and science-based transition plans, and invest in the global transition to clean energy.

Global Coal to Clean Energy Work

  • Ongoing work in 7 countries and Europe
  • Work launched in 2022 in 25 developing countries

Improving Global Air Quality

Bloomberg Philanthropies supports efforts that improve air quality management to reduce greenhouse gas emissions and protect public health. Since 2019, this work has helped seven cities — Brussels, Denver, London, Milan, Mumbai, Paris, and Warsaw — deploy hundreds of air quality sensors, analyze data, and pass policies to reduce pollution. We also partner at the national level with India and Indonesia to help manage air pollution and support the transition to clean energy. In total, we have helped pass more than 30 clean air policies.

Breathe London

Together with Mayor Sadiq Khan, we have supported the deployment of more than 200 low-cost air sensors across London to improve access to reliable, localized, real-time air quality data. The resulting data has helped Mayor Khan make the case for closing school streets to traffic and expanding the city’s Ultra Low Emissions Zone with charges for high-emitting vehicles. This work has led to four million more residents breathing cleaner air.

Strengthening Local Climate Action

Bloomberg Philanthropies invests in local climate action across the United States. America Is All In, which Mike co-chairs, is the most expansive coalition of leaders ever assembled in support of U.S. climate action, rallying thousands of cities, states, tribal nations, businesses, and more to meet the Paris Agreement goals. In 2022, the group released a landmark report that showed how the country, with the critical steps taken by local leaders together with ongoing federal action and funding, can meet its national target to halve carbon emissions by 2030.

We also work closely with two leading city networks committed to the climate fight: the C40 Cities Climate Leadership Group and the Global Covenant of Mayors for Climate & Energy. C40 includes nearly 100 major cities whose mayors have committed to reducing emissions and strengthening their climate resilience. Three-quarters of C40 cities are cutting per capita emissions faster than their national governments, and they have reduced air pollution by 5% since 2018. The Global Covenant is an alliance of more than 12,000 cities and local governments focused on creating ambitious targets to limit emissions and reporting on their progress. Mike serves as president of the board of C40 and as co-chair of the Global Covenant.

Protecting Ocean Ecosystems and Coastal Communities

Bloomberg Philanthropies works with global partners to protect the world’s ocean from the threats of climate change, overfishing, and pollution. In 2022, we launched a new phase of the initiative to help achieve the United Nations’ goal of protecting 30% of the ocean by 2030, boosted by the recent adoption of the Kunming-Montreal Global Biodiversity Framework. We are supporting global partners to advocate for data-driven solutions, community involvement, and policy change that can help safeguard marine ecosystems, including coral reefs. This work is critical both to the global climate fight and to the livelihoods of coastal communities.

Convening Global Leaders to Accelerate Action on Climate Change

Throughout 2022, Bloomberg Philanthropies brought together world leaders, mayors, experts, and climate advocates on critical environmental issues

In September, we co-hosted the Earthshot Prize Innovation Summit with The Earthshot Prize to highlight groundbreaking climate innovations and solutions.

In October, at the 2022 C40 World Mayors Summit in Buenos Aires, Argentina, the C40 Cities Bloomberg Philanthropies Awards recognized the 10 most ambitious, impactful, and replicable global climate projects in cities. The winning cities are cleaning the air, improving waste management, expanding green spaces and bus lanes, and much more.

In November, we served as an official partner for the UN’s COP27 climate summit in Sharm El-Sheikh, Egypt, where we made a series of major announcements to expand our work on the clean energy transition in developing countries, bring data and transparency to private sector climate commitments, and build new public-private partnerships. In the 45 days leading up to the summit, Bloomberg Philanthropies, Bloomberg L.P., and our partners also took more than 90 actions to support the UN’s climate agenda.
