The Top Ten Climate Developments of 2024

1. Batteries Become Everybody’s Best Friend

Battery prices continue to drop and their capacity continues to rise. The cost of electric vehicle (EV) batteries are now about 60 percent what they were just five years ago. And around the world, batteries have become key components in solar-plus-storage microgrids, giving people access to reliable power and saving the day for communities this past hurricane season.

2. Americans Get Cheaper (and Cleaner) Energy

State public utility commissions and rural electric co-operatives around the country are taking steps to deliver better service for their customers that also lowers their rates. At the same time, real momentum is building to prevent vertically integrated utilities from preferencing their coal assets when there are cleaner and cheaper alternatives available.

3. A Sustainable Shipping Future Gets Closer

More than 50 leaders across the marine shipping value chain — from e-fuel producers to vessel and cargo owners, to ports and equipment manufacturers — signed a Call to Action at the UN climate change conference (COP29) to accelerate the adoption of zero-emission fuels. The joint statement calls for faster and bolder action to increase the use of zero and near-zero emissions fuel, investment in zero-emissions vessels, and global development of green hydrogen infrastructure, leaving no country behind.

4. Corporations Fly Cleaner

In April, 20 corporations, including Netflix, JPMorgan Chase, Autodesk, and more, committed to purchase about 50 million gallons of sustainable aviation fuel (SAF), avoiding 500,000 tons of CO₂ emissions — equivalent to the emissions of 3,000 fully loaded passenger flights from New York City to London. SAF is made with renewable or waste feedstocks and can be used in today’s aircraft without investments to upgrade existing fleets and infrastructure.

5. More and More Places Go From Coal to Clean

Around the world, coal-fired power plants are closing down as communities switch to clean energy. From Chile to the Philippines to Minnesota coal-to-clean projects are creating new jobs, improving local economic development, and generating clean electricity. In September, Britain became the first G7 nation to stop generating electricity from coal — it’s turning its last coal-fired power plant into a low-carbon energy hub. And in Indonesia, the president vowed to retire all coal plants within 15 years and install 75 gigawatts of renewable energy.

6. Methane Becomes More Visible, and Easier to Mitigate

Methane — a super-potent greenhouse gas — got much easier to track thanks to the launch of new methane tracking satellites over the past year. In March, the Environmental Defense Fund launched MethaneSAT, the first for a non-governmental organization, and the Carbon Mapper Coalition soon followed with the launch of Tanager-1. By scanning the planet many times each day and identifying major methane leaks from orbit, these new satellites will put pressure on big emitters to clean up.

7. EVs Speed By Historic Milestones

This past year was the first time any country had more fully electric cars than gas-powered cars on the roads. It’s no surprise that this happened in Norway where electric cars now make up more than 90 percent of new vehicle sales. And in October, the United States hit a milestone, with over 200,000 electric vehicle charging ports installed nationwide.

8. Consumers Continue to Shift to Energy-Efficient Heat Pumps for Heating and Cooling

Heat pumps have outsold gas furnaces consistently since 2021. And while shipments of heating and cooling equipment fell worldwide in 2023, likely due to broad economic headwinds, heat pumps held on to their market share through. And over the past 12 months, heat pumps outsold conventional furnaces by 27 percent. Shipments are expected to continue increasing as states roll out home efficiency and appliance rebate programs already funded by the Inflation Reduction Act – worth up to $10,000 per household in new incentives for heat pump installations.

9. China Reaches Its Renewable Energy Goal, Six Years Early

China added so much renewable energy capacity this year, that by July it had surpassed its goal of having 1,200 gigawatts (GW) of clean energy installed by 2030. Through September 2024, China installed some 161 GW of new solar capacity and 39 GW of new wind power, according to China’s National Energy Administration (NEA). China is deploying more solar, wind, and EVs than any other country, including the United States, which is — by comparison — projected to deploy a record 50 GW of solar modules by the end of 2024.

10. De-carbonizing Heavy Industry

For steel, cement, chemicals and other heavy industries, low-carbon technologies and climate-friendly solutions are not only increasingly available but growing more affordable. To speed this process, Third Derivative, RMI’s climate tech accelerator, launched the Industrial Innovation Cohorts to accelerate the decarbonization of steel, cement, and chemicals. Also on the rise: clean hydrogen hubs — powered by renewable energy — designed to supply green hydrogen to chemical, steel, and other heavy industries to help them shift to low-carbon production processes.
