5 Reasons the US Should Cut its GHG Emissions in Half by 2030
Summary
This briefing by the World Resources Institute argues that the United States should set a greenhouse gas emissions-reduction target of 50% below 2005 levels by 2030. The document outlines how such a target is achievable through a combination of federal and local action, would stimulate economic growth and job creation, and is necessary to maintain international leadership and meet global warming limits of 1.5 degrees C.
Key insights
- The World Resources Institute recommends that the United States aim to reduce greenhouse gas emissions by 50% by 2030 compared to 2005 levels, asserting that this target is both "ambitious and attainable".
- Achieving a 50% reduction by 2030 is possible through an "All-in" strategy that combines aggressive federal engagement with local climate actions. The power sector is the most critical area, accounting for over 60% of estimated reductions in this scenario, while non-CO2 emissions like methane and hydrofluorocarbons (HFCs) represent roughly 17% of the potential reduction.
- Transitioning to a low-carbon economy offers significant employment opportunities. Renewable energy and energy efficiency investments generate more than twice as many jobs as fossil fuel spending for every $1 million invested. Widespread electrification could support up to 25 million jobs over 15 years and 5 million sustained jobs by mid-century, requiring annual public investments of approximately $300 billion for 10 years.
- Failure to implement new policies to reduce emissions could lead to severe economic damages. Annual losses from climate change could reach 1-3% of U.S. GDP by the end of the century, with a worst-case scenario reaching 3.7-10% of GDP, particularly impacting the Midwest and the South through crop yield declines, sea level rise, and extreme heat.
- A strong U.S. target is essential for global climate leadership and encouraging other major emitters—including China, India, Canada, Japan, South Korea, and South Africa—to increase their ambition ahead of COP26. The U.S. is responsible for 13% of current global emissions and has the highest cumulative emissions of any country.
- To support international goals, the U.S. should fulfill its outstanding $2 billion pledge to the Green Climate Fund (GCF) and increase contributions to the Global Environment Facility and the Adaptation Fund.
