The passage and July 4th, 2025, signing of the One Big Beautiful Bill Act (OBBB) was perhaps the most notable such milestone, but certainly not the only one. Collectively, this administration’s efforts risk substantially slowing emissions progress in many fields, from clean energy to EVs.
But for advocates of climate and clean energy who don't want to lose momentum, there are still reasons for optimism and resolve, despite the recent headwinds.
Because the thing is, the game is not over yet. In fact, if merely those of us who are still interested in reducing emissions just acted a little more strategically, we alone could more than compensate for all this lost climate progress, without needing action from those who don’t care about climate.
Let’s take a closer look at how the Trump administration’s shift in priorities might alter U.S. and global emissions trajectories. And how a small number of high-impact solutions, purely by voluntary actors who are already interested, could slash GHG emissions worldwide by an even larger amount.
How Trump 2.0 priorities and actions could shift U.S. emissions trends
Multiple analyses converge on substantial emissions impacts from Trump administration climate policy reversals. A recent Rhodium Group report examined the effect of regulatory rollbacks and the passage of the OBBB, finding that such shifts could result in an additional 315–574 million tonnes of annual emissions, or more than five cumulative gigatonnes over the next decade. Princeton University's REPEAT Project estimates the OBBB alone will add ~190 million tonnes annually by 2030 and 470 million tonnes by 2035. When compared to U.S. Paris Agreement targets, Carbon Brief calculated Trump's policy trajectory creates a 7 billion tonne gap through 2030.
Across these studies, the direct U.S. emissions impact ranges from roughly 3-7 Gt over the next 5-10 years. These estimates primarily focus on quantifiable policy rollbacks, but a comprehensive worst-case scenario, which includes a full IRA repeal, additional regulatory rollbacks, and indirect global effects, could potentially create a 15-20 Gt emissions gap.
Yet even in the face of the Trump administration’s rollback of climate policy, there are straightforward solutions the private sector can implement now that would make up that emissions difference. Passionate and effective climate action still exists in the United States, with the capacity to do much good. It can be found at the subnational and private sector levels.
Four ways U.S. and multinational companies could slash emissions without federal support
1. Build new renewables in better locations.
Last year, global annual investment in the low-carbon energy transition surpassed US$2 trillion for the first time, according to BloombergNEF. Fully two-thirds of last year’s US$3 trillion in total energy investment went to clean energy and other low-carbon technologies. China is building so many renewables so fast that it’s disrupting Central Asia’s natural gas markets. Worldwide, renewable energy accounted for 92% of new electricity generation in 2024. (The story is nearly identical for the U.S. power sector, too.) Voluntary corporate procurement has been an important part of that growth, too – corporate clean energy contracting reached record levels last year.
And here’s the big, beautiful thing: if we took all this ongoing investment purely from actors who are not backing away from clean energy, and merely targeted it toward better, smarter locations, we could unlock gigatonnes of additional emissions reductions. It’s a strategy called emissionality.
