What would be the extent of this increase in greenhouse gases (GHG)?
According to the specialized media Carbon Brief1Trump administration decisions will add 7 billion tonnes of CO2 In the American balance sheet by 2030. It is the equivalent of twice and a half times the annual emissions of a country like India. Note that in 2023, total emissions from the United States amounted to 4.9 billion tonnes.
How do you get to this estimate?
Carbon Brief based on a recent report produced by researchers from Princeton University, who analyzed the impact of One Big Beautiful Bill Act (OBBBA) on the climate trajectory of the United States. However, the specialized media has raised wider and compared the impact of the American president’s decisions on the former objective set by the Biden administration to reduce GHGs from 50 % to 52 % compared to 2005, by 2030. According to Carbon Brief, in this new context, American emissions will rather decrease by 20 % by 2030 compared to 2005.
We talk a lot about this One Big Beautiful Bill Actbut what exactly is it?
It is a new budgetary law promoted by Donald Trump which rakes very wide. It provides in particular a lower taxes, and more specifically the elimination of renewable energies subsidies, such as solar and wind, as well as the implementation of a tax on any new renewable energy project. This law, which was promulgated by the American president on July 4, follows several decisions favorable to the deployment of fossil fuels in the United States.
What will be the concrete impacts of One Big Beautiful Bill Act ?
“In short, the One Big Beautiful Bill Act increases the energy costs of American households and companies, will increase taxes on new renewable energy projects at a time when demand is rapidly growing, and will considerably increase greenhouse gas emissions from the United States. It seems to me a very bad bill… “, commented Jesse Jenkins on the X network. Engineer in energy systems and professor at Princeton University, Mr. Jenkins is also Director of the Repeat project, for Rapid Energy Policy Evaluation and Analysis Toolkit, or toolbox for the quick evaluation and analysis of energy policies in French. Launched in 2021, the Repeat project has already produced several reports 2 illustrating the impacts of public policy on the energy transition in the United States. His most recent analysis, published on July 3, has looked into the effects of One Big Beautiful Bill Act.
Does the report give more details?
The Repeat project team has estimated several potential impacts associated with this law, which according to them will result in an increase in GHG emissions in the United States of 2 % in 2030 and 7 % in 2035. Its report also provides for an increase of US dollars for energy expenditure for households and companies in 2030. These expenses will climb more than $ 50 billion 2035. The new law will also result in a substantial reduction in investments in renewable energies of US $ 500 billion. “This bill fundamentally and substantially dismantled the policy implemented by the previous congress and administration. He thus brings us back to a much slower decarbonization trajectory, ”said Jesse Jenkins to the magazine Scientific American.
