In 2023, France recordsone of the most significant reductions in greenhouse gas emissions after 2020 (Covid crisis) and 2014 (particularly mild winter). This decline represents no less than 22.8 million tonnes of CO2 equivalent less compared to 2022. The latest available data show for the first time a decline in all major emitting sectors such as transport, industry and even transport. ‘agriculture.
In Franche-Comté, GHG emissions amount to 10 million tonnes of CO2 equivalent in 2021according to the latest data available at the local level. Doubs and Jura concentrate the vast majority of these discharges with proportions reaching 42% and 30% respectively.
26% for road traffic
The main emitter of greenhouse gases in this territory is road traffic. This sector accounts for 26% of emissions. With the map by municipality, we locate a concentration of emissions around the A36 and particularly around Belfort, Montbéliard and Besançon. In the Meuse, we observe the route of the A4.
Compared to the surface area of the territories, emissions reach peaks in certain municipalities. Botans near Andelans (Territoire de Belfort) records the largest emissions linked to road traffic per km2. This town is crossed by the N19 and the A36. We also see strong emissions in Arbouans between Montbéliard and Audincourt or even in Phaffans in the Territory of Belfort.
Emissions in this sector are generally decreasing. We can observe short-term effects with the increase in fuel prices. In the medium and long term, it is the renewal of the vehicle fleet with electric vehicles that has an effect. Another impact is the evolution of habits linked to mobility with carpooling or cycling.
21% for residential
The residential sector comes in second position in Franche-Comté with 21% of emissions. They mainly come from the use of fossil fuels for heating. Relative to the surface area of each territory, the municipalities of Lons-le-Saunier, Belfort and Montbéliard are among those where this problem is most marked.
Nationally, greenhouse gases associated with this sector have reached their lowest level since 1990. This development can be explained by several factors: inflation, rising energy prices, colder winters. lenient conditions and behavioral changes promoting better energy sobriety.
21% for agriculture
Agriculture represents 21% of emissions linked to human activities. At the local level, the municipalities of Sechin (Doubs), Boursières (Haute-Saône) and Villars-le-Sec (Territoire de Belfort), display the highest concentrations in this area.
The reduction in this agricultural impact is explained by the reduction of two main gases: nitrogen dioxide (NO2), resulting from the use of organic and mineral fertilizers, and methane (CH4) linked to cattle and pig herds.
19% for industry and energy
The industry and energy sectors account for 19% of this territory’s emissions. This figure even rises to 33% in Jura, ahead of Doubs (16%).
It is at Works in the Jura that we perceive the strongest emanations linked to industry. The Solvay chemical factory is located in this town. In second position, we find Sochaux in Doubs where the Stellantis factory and automobile subcontractors are located.
