Since 2004, the City of Paris has assessed the greenhouse gas emissions of its territory. In accordance with the Climate Plan, the balance of greenhouse gas emissions is evaluated every 5 years. It was published for the years 2004, 2009 and 2014. This new edition shows Paris’s greenhouse gas emissions for 2018 and their projections to 2020. This inventory identifies the contribution from each sector of activity, the emissions generated by lifestyles and the influence of local, national and European policies.

This work is carried out with a large number of external partners, city managers and Airparif. The entire balance sheet was subject to an independent audit and certification by the Sustainable Metrics design office, ensuring methodological compliance and the validity of the results.

Paris 'carbon footprint amounted to 22.7 million tonnes of CO2 equivalent (tCO2e) in 2018. Paris' carbon footprint was down 20% at the end of 2018 compared to 2004. Air transport (33 %), and food (17%) remain the first two most emitting sectors. All sectors are experiencing a decline, including aviation. For this sector, this change comes mainly from the reduction in air freight traffic. Food emissions are down 10% from 2004 due to less meaty and more sustainable food.

In 2018, local emissions in Paris amounted to 5.5 MtCO2e, down to 25% compared to 2004. This concerns emissions generated by the energy consumption of buildings and vehicles traveling in Paris and the treatment of waste. This significant decrease is attributed to the effects of sobriety in the uses of buildings and transport as well as changes in behavior towards practices that emit less carbon.

For road transport, the effects of European and national regulations (Euro standards) coupled with local land-use planning decisions (reduction of the car space, improvement of public transport circulation and shared mobility, restricted traffic area, etc.) ) generate substantial gains, particularly in the intramural area, with -36% compared to 2004.


Paris’s energy consumption amounted to 30.8 TWh in 2018, down by 9%. Electricity remains the first energy consumed in Paris ahead of natural gas. Fuel oil consumption has dropped by 43% in 14 years. Fuel oil remains the most emitting and polluting energy used in Paris. The increase in renewable energies in the CPCU's energy mix (wood for coal in St-Ouen, elimination of oil-fired power plants, use of geothermal energy) has made possible to reduce emissions from the distributed steam.

Regarding the carbon neutrality trajectories adopted by the Paris Climate Plan of 2018, the trends are green and encourage to persist in this evolution. This involves numerous collective, public, private, entrepreneurial and individual co-responsibilities. The next decade is crucial. The main projects, included in the Paris Climate Plan in 2018, will have to be implemented quickly.
