Cuts to clean energy spending in the recent legislation signed into law by President Donald Trump could have significant implications for the environment. The new law is expected to result in billions of additional tonnes of CO2 emissions over the next decade, pushing the US further away from its climate goals. The US, which is the world’s second-largest emitter of greenhouse gases, was already lagging behind in its commitment to reduce emissions by 50% by 2030 under the Paris Agreement.
According to early estimates, the legislation, known as the “One Big Beautiful Bill Act,” includes cuts to clean energy funding as part of a larger package that includes tax cuts and increased spending on immigration enforcement and the military. These cuts will eliminate tax credits aimed at promoting low-emission energy sources, hindering the progress that was expected under previous policies.
An analysis by researchers at Princeton University projected that the new law would slow down the decline in US greenhouse gas emissions, effectively reversing the progress that was anticipated under the previous administration’s initiatives. This change is expected to have a significant impact on emissions levels in the coming years.
Since 2005, US emissions have decreased by about 17%, with further reductions projected by 2030. However, under the new law, these reductions are expected to be smaller, leading to a substantial increase in emissions compared to previous estimates. This setback will make it challenging for the US to meet its emissions targets under the Paris Agreement.
The legislation also includes the phasing out of tax credits for electric vehicles and renewable energy projects, as well as the cancellation of funding for clean energy research and development programs. While some tax credits for low-emission electricity sources will remain available until 2033, the overall impact of the law on clean energy production and emissions reduction is concerning to climate advocates.
Environmental groups have criticized the legislation for its potential to increase emissions and undermine efforts to transition to a cleaner and more sustainable energy system. The decision to prioritize tax cuts and military spending over investments in clean energy has raised concerns about the future of climate action in the US.
