President Donald Trump’s dismantling of climate policy means the US will add an extra 7bn tonnes of emissions to the atmosphere from now until 2030, compared to meeting its former climate pledge under the Paris Agreement.
Since winning office last November, he has issued a series of executive orders and is poised to sign his “big beautiful bill” that effectively terminates Biden-era climate policies.
Carbon Brief’s analysis of modelling from the Princeton University REPEAT Project shows that this means US emissions are now set to drop to just 3% below current levels by 2030 – effectively flatlining – rather than falling 40% as required to hit the now-defunct target.
This would leave the US around 2bn tonnes short of its greenhouse-gas emissions target for that year, adding emissions equivalent to around 4% of the current global total each year
To put this in context, it is roughly the annual output of Indonesia, the world’s sixth-largest emitter.
Trump is already withdrawing his nation from its international climate obligations under the Paris Agreement.
The passage of the new Republican-backed “megabill” means that US climate targets pursued by Trump’s predecessor now appear firmly out of reach.
7bn tonnes
Trump is due to sign the so-called “big beautiful bill” into law after it was approved by the Republican-controlled US Congress on 3 July.
This “megabill” removes virtually all of the tax credits for renewable energy, electric vehicles and clean manufacturing that were at the core of Biden’s landmark Inflation Reduction Act (IRA).
Since his return to the White House, Trump has moved to strip away his predecessor’s climate policies, including via a series of executive actions. This includes targeting vehicle fuel-efficiency standards and power sector emissions standards.
The passage of the new bill means US solar and wind power expansion will likely slow down, as will sales of electric vehicles and energy efficiency improvements. The combined effect of these policy rollbacks can be seen in the chart below, based on modelling by the REPEAT Project.
Carbon Brief has compared the impact of Trump’s policies, including the megabill, to a pathway on which the US meets its former target, under the Paris Agreement, to cut greenhouse gas emissions by 50-52% from 2005 levels by 2030.
The cumulative gap between this pathway and the Trump administration’s trajectory amounts to 7bn tonnes of emissions over the next five years.
Under this new set of US policies, emissions are only expected to be 20% lower than 2005 levels by 2030, rather than 50-52%, meaning the nation would be 2bn tonnes short of its goal.
This amounts to just a 3% drop from 2024 levels by 2030, meaning emissions are effectively flatlining.
Renewables down, prices up
Among the hundreds of provisions in the new Republican-backed bill are several key rollbacks that are expected to affect US emissions.
Under the IRA, wind and solar projects could receive tax credits up to 2034. Following the Republican bill, most projects would need to start construction within the next year to qualify.
Without federal support, the pipeline of new renewable-energy projects is expected to contract.
The REPEAT analysts estimate that cumulative new solar capacity additions will drop by 29 gigawatts (GW) by 2030 and around 140GW by 2035. For wind power, the decrease is set to be 43GW by 2030 and 160GW by 2035.
Some renewable projects will likely be built without support, but developers will need to contend with other Trump administration policies, such as stopping federal windfarm approvals.
The lost renewable capacity is unlikely to be entirely replaced by fossil fuels, due to a multi-year backlog in the construction of gas-fired power plants.
Tax credits for nuclear and geothermal power have been retained until 2036 in the bill. While these projects generate clean electricity, they can also take a long time to build.
Other key policies in the new bill include the removal of tax credits worth up to $7,500 to purchase electric vehicles, which could result in tens of millions fewer such cars and vans being sold. Ending tax credits for low-carbon manufacturing is also expected to undo progress in building clean technologies, such as solar panels and electric cars, domestically.
Beyond its effect on US emissions, various early analyses have suggested the Republican-backed bill is likely to increase energy prices and lead to job losses.
REPEAT estimates household energy costs are likely to be $165 higher in 2030 and more than $280 higher by 2035, following the passing of the bill.
Some of this increase can be attributed to fewer electric vehicles on the road, leading to higher petrol and diesel consumption and prices. Slowing construction of solar and wind projects as power demand increases will also likely affect the cost of electricity.
Without tax credits to boost the construction of new generation capacity, residential electricity prices are set to increase by 7% – or $110 – by 2026, for the average US customer, according to analysis conducted for trade body the Clean Energy Buyers Association.
In the state of Wyoming, the same analysis found that electricity prices may rise by as much as 30% over the next year. Other firmly Republican states, such as North Carolina and Tennessee, are also expected to see near-term price rises in the double digits.
Methodology
Modelling of the impact of the Trump administration’s “big beautiful bill” is from the REPEAT Project, a joint initiative of the Princeton University ZERO Lab and Evolved Energy Research.
The project has assessed the emissions impact of the executive actions that the Trump administration has already taken to unwind Biden-era policies, as well as the bill itself.
Carbon Brief compared this trajectory out to 2030 with a straight-line pathway towards the official US climate target for 2030. This is set out in the US’ nationally determined contribution (NDC) under the Paris Agreement. It is worth noting that the Trump administration is withdrawing the US from the Paris Agreement.

Half of nations have met a UN deadline to report on how they are tackling nature loss within their borders, Carbon Brief analysis shows.
This includes 11 of the 17 “megadiverse nations”, countries that account for 70% of Earth’s biodiversity.
It also includes all of the G7 nations apart from the US, which is not part of the world’s nature treaty.
All 196 countries that are part of the UN biodiversity treaty were due to submit their seventh “national reports” by 28 February, of which 98 have done so.
Their submissions are supposed to provide key information for an upcoming global report on actions to halt and reverse biodiversity loss by 2030, in addition to a global review of progress due to be conducted by countries at the COP17 nature summit in Armenia in October this year.
At biodiversity talks in Rome in February, UN officials said that national reports submitted late will not be included in the global report due to a lack of time, but could still be considered in the global review.
Tracking nature action
In 2022, nations signed a landmark deal to halt and reverse nature loss by 2030, known as the “Kunming-Montreal Global Biodiversity Framework” (GBF).
In an effort to make sure countries take action at the domestic level, the GBF included an “implementation schedule”, involving the publishing of new national plans in 2024 and new national reports in 2026.
The two sets of documents were to inform both a global report and a global review, to be conducted by countries at COP17 in Armenia later this year. (This schedule mirrors the one set out for tackling climate change under the Paris Agreement.)
The deadline for nations’ seventh national reports, which contain information on their progress towards meeting the 23 targets of the GBF based on a set of key indicators, was 28 February 2026.
According to Carbon Brief’s analysis of the UN Convention on Biological Diversity’s online reporting platform, 98 out of the 196 countries that are part of the nature convention (50%) submitted on time.
The map below shows countries that submitted their seventh national reports by the UN’s deadline.
This includes 11 of the 17 “megadiverse nations” that account for 70% of Earth’s biodiversity.
The megadiverse nations to meet the deadline were India, Venezuela, Indonesia, Madagascar, Peru, Malaysia, South Africa, Colombia, Mexico, the Democratic Republic of the Congo and Australia.
It also includes all of the G7 nations (France, Germany, the UK, Japan, Italy and Canada), excluding the US, which has never ratified the Convention on Biological Diversity.
The UK’s seventh national report shows that it is currently on track to meet just three of the GBF’s 23 targets.
This is according to a LinkedIn post from Dr David Cooper, former executive secretary of the CBD and current chair of the UK’s Joint Nature Conservation Committee, which coordinated the UK’s seventh national report,
The report shows the UK is not on track to meet one of the headline targets of the GBF, which is to protect 30% of land and sea for nature by 2030.
It reports that the proportion of land protected for nature is 7% in England, 18% in Scotland and 9% in Northern Ireland. (The figure is not given for Wales.)
National plans
In addition to the national reports, the upcoming global report and review will draw on countries’ national plans.
Countries were meant to have submitted their new national plans, known as “national biodiversity strategies and action plans” (NBSAPs), by the start of COP16 in October 2024.
A joint investigation by Carbon Brief and the Guardian found that only 15% of member countries met that deadline.
Since then, the percentage of countries that have submitted a new NBSAP has risen to 39%.
According to the GBF and its underlying documents, countries that were “not in a position” to meet the deadline to submit NBSAPs ahead of COP16 were requested to instead submit national targets. These submissions simply list biodiversity targets that countries will aim for, without an accompanying plan for how they will be achieved.
As of 2 March, 78% of nations had submitted national targets.
At biodiversity talks in Rome in February, UN officials said that national reports submitted late will not be included in the global report due to a lack of time, but could still be considered in the global review.
Funding ‘delays’
At the Rome talks, some countries raised that they had faced “difficulties in submitting [their national reports] on time”, according to the Earth Negotiations Bulletin.
Speaking on behalf of “many” countries, Fiji said that there had been “technical and financial constraints faced by parties” in the preparation of their seventh national reports.
In a statement to Carbon Brief, a spokesperson for the Global Environment Facility, the body in charge of providing financial and technical assistance to countries for the preparation of their national reports, said “delays in fund disbursement have occurred in some cases”, adding:
“In 2023, the GEF council approved support for the development of NBSAPs and the seventh national reports for all 139 eligible countries that requested assistance. This includes national grants of up to $450,000 per country and $6m in global technical assistance delivered through the UN Development Programme and UN Environment Programme.
“As of the end of January 2026, all 139 participating countries had benefited from technical assistance and 93% had accessed their national grants, with 11 countries yet to receive their funds. Delays in fund disbursement have occurred in some cases, compounded by procurement challenges and limited availability of technical expertise.”
The spokesperson added that the fund will “continue to engage closely with agencies and countries to support timely completion of NBSAPs and the seventh national reports”.

Facing multiple lawsuits, Dow requests an “unprecedented” permit amendment to authorize its discharge of polyethylene pellets into coastal waters.
Two weeks ago, when Texas sued a massive Dow petrochemical plant over water pollution, state environmental regulators were already considering a novel proposal from the company that would effectively legalize discharges of plastic material from the 4,700–acre complex into waters feeding San Antonio Bay and the Gulf of Mexico.

As Democrats and climate activists seize on energy costs as a political issue, new data shows electricity rates rose 5 percent nationwide in 2025. The figures were much higher in some states.
COLUMBUS, Ohio—Protestors stood in the snow outside the offices of Ohio’s utility regulator in January to say they were fed up with rising electricity rates.
