Will increase in electrical energy demand and continued development in transport emissions led to US emissions remaining broadly “unchanged”, whereas the financial system grew by 2.7 per cent, the New York-based analysis group finds.
Though emissions remained unchanged from a 12 months earlier, they had been nonetheless 8 per cent beneath pre-pandemic ranges in 2024 and remained about 20 per cent beneath 2005 ranges, Rhodium notes.
Whereas the tempo of decarbonisation slowed in 2024, after a discount of 1.9 per cent in 2023, new insurance policies and laws launched underneath the Biden administration had been anticipated to see this speed up within the coming years, Rhodium says.
Nonetheless, it notes that this progress may now be in danger from the incoming presidency of Donald Trump. Trump has repeatedly pledged to roll again a variety of environmental insurance policies introduced in by his predecessor Joe Biden.
Renewable vitality within the US grew in 2024, with the mixed output from photo voltaic and wind surpassing coal within the electrical energy combine for the primary time ever, in keeping with Rhodium.
Collectively, photo voltaic and wind made up 16 per cent of the electrical energy combine in 2024, up almost two share factors from 2023. Photo voltaic era grew by 32 per cent and wind by 7 per cent, each outpacing the 4 per cent development in fuel era, the report notes.
Photo voltaic had a record-setting 12 months in 2024, accounting for 64 per cent of all new electricity-generating capability added to the US grid in Q3, in keeping with the Photo voltaic Power Industries Affiliation.
Nonetheless, the rollout of wind era was hit by notable challenges, together with elevated prices and venture siting difficulties.
Gasoline-fired electrical energy era remained the single-largest supply within the US by far, producing a report 1,782 terawatt hours (TWh) in 2024, some 43 per cent of the entire.
Nuclear was the second-largest, as proven within the determine beneath. It generated 781TWh, some 19 per cent of the entire, simply forward of the mixed output of wind and photo voltaic, in addition to coal.

The expansion of wind and photo voltaic helped make sure that the era combine was “barely cleaner” in 2024, regardless that demand for electrical energy rose by 3 per cent, says Rhodium.
Buildings represented the largest improve in demand for electrical energy, the place a ten per cent development in “cooling diploma days” – a measure of how scorching the temperature is – drove up summer time electrical energy use. (The US noticed record-breaking heatwaves throughout the 12 months, with the summer time of 2024 the most popular on report, the Guardian reported.)
After buildings, business ranked second and industrial buildings third as the largest sources of elevated electrical energy demand.
There was a whole lot of media focus on synthetic intelligence (AI) driving electrical energy demand development. Furthermore, a Division of Power-commissioned research in December discovered that US knowledge centre energy demand may almost triple inside 4 years, consuming as a lot as 12 per cent of the nation’s electrical energy by 2028.
Nonetheless, Rhodium notes that knowledge centres had been solely a small supply of demand development in 2024, representing only a fraction of the third greatest supply of electrical energy demand.
In 2024, the extra energy demand was met by fuel, wind and photo voltaic, whereas coal continued to say no, dropping one share level to 16 per cent of the electrical energy combine.
In absolute phrases, coal offered as a lot energy in 2024 because it did in 1967 when Lyndon Baines Johnson was the thirty sixth president of the US, the Vietnam Battle was raging and Elvis Presley married Priscilla Ann Beaulieu in Las Vegas.
Gasoline remained the one largest supply of energy within the US in 2024, accounting for 43 per cent of the entire (1 share level greater than in 2023), notes Rhodium.
This development – to fulfill elevated demand – offset the discount in coal era and emissions from the ability sector elevated by 0.2 per cent (3m tonnes of carbon dioxide equal, MtCO2e) in 2024.
Alongside the rise in renewable vitality, the US noticed record-high funding within the manufacturing and deployment of fresh applied sciences final 12 months, Rhodium says.
For instance, funding in clear applied sciences accounted for five per cent of complete personal funding in buildings, tools and sturdy client items within the third quarter of final 12 months, in keeping with the newest knowledge from the Clear Funding Monitor.
Crude oil manufacturing was up by 2.4 per cent in 2024, whereas fuel manufacturing fell by 0.6 per cent, in keeping with Rhodium. This was a barely larger drop in fuel manufacturing than in 2020 when the Covid pandemic hit, as producers reacted to decrease costs by drilling fewer new wells and curbing manufacturing, it provides.
The analysis estimates that oil and fuel programs launched round 10 per cent much less methane per unit of output in 2024 than in 2022, as a result of cleaner manufacturing practices in addition to state and federal laws.
As such, cleansing up oil and fuel manufacturing led to a 3.7 per cent drop in emissions from the sector, some 11MtCOe relative to 2023.
Hurricanes hit industrial emissions
Industrial emissions fell in 2024 as a result of low manufacturing output, Rhodium finds. Throughout the 12 months, the sector’s emissions fell by 1.8 per cent, or 22MtCO2e, from 2023.
Chemical compounds, computer systems and electronics, and paper manufacturing grew in 2024, however declines in meals and drinks, mining and equipment offset these positive aspects, it says.
This included traditionally low coal mining exercise, which fell by 12 per cent in 2024 to its lowest degree in a long time as a result of demand falling, as coal energy vegetation retire and are changed by renewables and fuel, as famous within the part above.
One consider declining industrial output was excessive climate. Together with the influence of labour disruption on manufacturing, Hurricanes Beryl, Milton and Helene additionally all hit manufacturing output, notes Rhodium.
Transport remained the highest-emitting sector within the US, with a 0.8 per cent improve in emissions pushed by post-pandemic rebounds in jet gasoline and petrol consumption, in keeping with Rhodium.
Emissions from transport, business and buildings have remained comparatively regular in current a long time, whereas the ability sector has seen regular declines, as proven within the determine beneath.

“Obtainable seat miles” – a metric used to quantify air journey – set a brand new report in 2024, up 6 per cent year-on-year within the first three quarters of the 12 months, in keeping with Rhodium.
There was additionally “record-high highway exercise” the report notes, with a 1 per cent improve in highway site visitors volumes as much as October. As such, petrol consumption elevated, though diesel continued to fall, dropping near 2020 ranges.
Regardless of these will increase in transportation exercise, emissions from the sector nonetheless stay 2. per cent per cent beneath 2019 ranges.
Constructing sector emissions elevated by 0.4 per cent as a result of elevated gasoline use, Rhodium provides.
Wanting forward
The “modest 2024 decline underscores the urgency of accelerating decarbonisation in all sectors” concludes Rhodium, specifically with the approaching change in US authorities.
At the moment, the US is just not on monitor to fulfill both its 2030 Paris Settlement goal of a 50-52 per cent discount in emissions relative to 2005 ranges or its newly set 2035 purpose of a 61-66 per cent discount.
To bridge the hole between the present US trajectory and its said objectives would require a mean emissions discount of seven.6 per cent yearly from 2025 by to 2030, says Rhodium. This could be greater than two-thirds of the drop seen on account of Covid lockdowns in 2020.

Analysts, together with Rhodium, have predicted that the mixed influence of the Inflation Discount Act (IRA), Infrastructure Funding and Jobs Act and Environmental Safety Company (EPA) laws on autos and energy vegetation will improve the tempo of emissions reductions sooner or later.
There may be already some proof of this, with the latest knowledge from Clear Funding Monitor suggesting that clear vitality and transportation funding may attain a excessive of US$71 billion within the third quarter of 2024.
This could cap the “almost unbroken streak of quarter-on-quarter development because the IRA’s passage, with clear funding now accounting for a report 5 per cent of complete US personal funding”, notes Rhodium.
Nonetheless, whether or not the speed of emissions discount really accelerates is closely depending on the extent to which the incoming Trump administration and the Republican Congress rollback and repeal EPA laws and vitality and tax insurance policies introduced in or expanded by the IRA.
Trump has repeatedly promised to tug again local weather insurance policies, saying in September 2024 that “to additional defeat inflation, my plan will terminate the Inexperienced New Deal, which I name the Inexperienced New Rip-off” in reference to the IRA, in keeping with Politico.
In December, Rhoiodum printed a separate piece of analysis dubbed: “Trump 2.0: What’s in Retailer for US Power and Local weather?” It explored quite a lot of potential pathways the Trump administration may pursue when he takes workplace on 20 January, together with one known as “rollbacks and repeal”.
This pathway would see the tempo of US decarbonisation sluggish considerably, leaving emissions at 24-40 per cent beneath 2005 ranges in 2035. That is equal to roughly a further 1 billion tonnes of CO2e in 2035 in every emissions state of affairs explored by Rhodium.
Rolling again laws alone may result in a 270-470MtCO2e improve in emissions by 2035, it provides. This could characterize 25-50 per cent of the entire emissions improve underneath the complete “rollbacks and repeal” pathway.
Evaluation by Carbon Temporary in March 2024 discovered that Trump successful November’s presidential election may result in a cumulative further 4 billion tonnes of US emissions by 2030, in comparison with underneath Bidens’s plans.
Ben King, co-author of the preliminary emissions evaluation and Trump 2.0 observe, and an affiliate director in Rhodium Group’s vitality and local weather follow, tells Carbon Temporary:
“It’s not clear what exact coverage actions the Trump administration and Republican-controlled Congress will take, however we analysed the potential impacts of two main coverage adjustments: rolling again main local weather laws from the Environmental Safety Company (EPA) and repealing the vitality and tax insurance policies that had been enhanced and expanded by the Inflation Discount Act (IRA). Rolling again EPA local weather laws alone – which the Trump administration may pursue unilaterally, although not instantly – may improve greenhouse fuel emissions by 270-470MtCO2e in 2035.
“A extra excessive coverage pathway, rolling again EPA laws and instantly repealing the vitality and tax elements of the IRA – which might require congressional approval – may improve emissions by almost 1GtCO2e in 2035.”
Rhodium concludes its evaluation of the US’s emissions in 2024 by noting that it will likely be watching developments round rolling again and repealing local weather insurance policies “carefully”.
