On October 13, 2026, Citepa announced that France’s greenhouse gas emissions are expected to fall by 2.8% in 2026, reaching a level of 349.4 million tonnes of CO2 equivalent. This projection marks a slight acceleration from the 2.1% decrease recorded for the whole of 2025. The agency presented the figure as part of its regular emissions barometer, noting that the decline is mainly driven by reduced natural gas consumption in the residential, commercial and public sectors and a drop in road transport activity.
Citepa also reported that, for the first half of 2026, emissions had already fallen by 4.1% compared with the same period in 2025. This half‑year figure was highlighted in a separate statement from the agency, which said that the reduction was "nettement en deçà du rythme moyen annuel de réduction nécessaire pour atteindre les objectifs climatiques à l’horizon 2030" – clearly below the average annual cut needed to meet climate goals by 2030. The first‑half data pointed to a sharper decline in transport and buildings than the full‑year estimate would later suggest.
The transport sector, identified as the largest source of emissions, is expected to see a 4.8% drop in 2026. This decline is linked to a 7.3% fall in diesel sales during the first half of the year, a development that Citepa attributed to rising fuel prices exacerbated by the Middle East conflict. In the building sector, the residential, commercial and public segments together recorded a 12% reduction in emissions, driven by lower heating demand and decreased natural gas use. This building sector reduction contributed to the overall decline.
This anticipated increase would offset some of the gains made elsewhere and contributes to the agency’s caution that the overall trend may weaken later in the year.
While transport and buildings are pulling emissions down, the energy industry is projected to move in the opposite direction. Citepa warned that emissions from the energy sector could increase by 3.6% compared with 2025, reflecting a potential rise in gas‑fired power generation in the second half of 2026. This anticipated increase would offset some of the gains made elsewhere and contributes to the agency’s caution that the overall trend may weaken later in the year.
The 2.8% projected drop for 2026 represents an improvement over the 2.1% cut seen in 2025, yet it remains well short of the pace required to achieve France’s national climate ambition. The government has committed to cutting greenhouse gas emissions by at least 50% by 2030 relative to 1990 levels. To stay on track for that target, an average annual reduction of roughly 5% would be needed between 2024 and 2030. The current forecast therefore falls below both the required rate and the 3.1% carbon budget set for the 2024‑2028 period by the third National Low Carbon Strategy.
Ecological Transition Minister Monique Barbut welcomed the news, saying in French that "Cette baisse annuelle des émissions de GES est encourageante, mais ne suffit pas encore à atteindre nos objectifs climatiques." In English, she described the yearly decrease as encouraging but still insufficient to meet climate goals. She reiterated this view in another comment, calling the drop "encouraging" while stressing that it does not yet suffice to reach the nation’s objectives.
In contrast, Anne Bringault of the Network for Climate Action struck a more critical tone. She declared that "L’accélération de la transition écologique et juste n’est pas encore là," meaning that the acceleration of a just ecological transition has not yet arrived. She also warned that high fuel, heating and food prices – intensified by the Middle East conflict and by climate‑driven droughts and heatwaves – are becoming unbearable for many households and businesses, underscoring the social pressures that accompany the shift away from fossil fuels.
Taken together, the data show a real but modest decline in France’s greenhouse gas output for 2026, driven chiefly by lower diesel consumption and reduced heating demand. At the same time, the projected rise in energy‑sector emissions and the continued reliance on carbon‑intensive fuels mean that the overall pace of decarbonisation remains insufficient. Officials and analysts agree that, without a faster acceleration of the ecological transition – one that addresses both technical and social dimensions – the country will fall short of its 2030 ambition to halve emissions compared with 1990 levels.
