The U.S. Strengthened its Climate Pledge. Will Other Countries Follow Suit?

The Inflation Reduction Act isn’t perfect, but the U.S. blueprint for major emissions reductions is on the table for the world to see.

By Leonardo Lacerda, Global Managing Director, Climate; Darci Vetter, Global Head, Policy and Government Relations

Signed into law in August, the Inflation Reduction Act (IRA) represents the single biggest climate investment in U.S. history—by far.

The landmark law invests $369 billion in renewable energy, zero carbon transportation, clean manufacturing, community resilience, and natural climate solutions.

These investments deliver on a long list of priorities that The Nature Conservancy promotes to drive down greenhouse gas emissions, build more resilient communities, and enhance equitable outcomes.

Rebuilding trust after Paris

Science tells us that in order to avoid the most catastrophic impacts of climate change, we need to keep global temperatures below a 1.5-degree rise from pre-industrial levels. This is simply not possible without the U.S. taking action. The IRA would put the U.S. on a path to roughly 40% emissions reduction by 2030.

The Paris Agreement was built on trust between countries that they would all take action together, and not create economic disparities between those who act and those who do not.

When the U.S. pulled out of the Paris Agreement, other countries questioned why they should continue to reduce their own emissions if the U.S. wasn’t. But when the U.S. reversed course last year and put forward a new commitment pledging 50-52% reductions, the globe noticed. Some trust returned, and it was not a surprise to see other major economies such as Canada, Japan and China soon enhance their own targets.

Delivering a blueprint for how

While the U.S. return to Paris was greeted with hope, it also came with skepticism. Would the U.S. be able to transform its promise into action? How could the U.S. meet its 50-52% pledge without domestic legislation?

The U.S. has at last delivered the blueprint for HOW it will reduce emissions, which we hope results in other countries following suit and strengthening their own pledges.

The IRA is expected to generate rapid new deployment of renewable energy in the U.S., creating healthy competition for renewable energy technologies, which should reverberate to decrease prices and barriers to adoption globally. Tax credits for the purchase of electric vehicles, and continued incentives for other energy-saving technologies should also drive production and demand that will benefit consumers beyond U.S. borders.

Implementation of the IRA is also an opportunity to learn, and to share what the U.S. learns with other governments looking to spur climate action. Transparency about the use of the IRA’s incentives, how costs and benefits are shared across geographies and communities, and unanticipated barriers to adoption will be critical to ensuring that our efforts are efficient, effective, and just.

We are not yet on target to meet the 1.5-degree goal. But each time one country ratchets its emissions down, the globe’s chances improve.

More aggressive steps to realize the role nature can play

The IRA does not contain everything we hoped for. We will need further, aggressive steps to transform our economy to renewable energy, and we will need additional measures to ensure that we fully realize the role nature can play in mitigation and adaptation.

We are not yet on target to meet the 1.5-degree goal. But each time one country ratchets its emissions down, the globe’s chances improve. TNC stands ready to work alongside our government and industry leaders to demonstrate pathways that can deliver deeper mitigation and adaption strategies and help people and nature.
