GHG emissions from transport

GHG emissions from transport in France

Note: "Transport not included in total" emissions refer to international sea, river and air transport. Data for 2022 are preliminary estimates.
Source: Secten format - Citepa, 2023

In 2022, in a context of gradual upturn in traffic from the second half of 2021, transport emissions increased by 2.3%, without returning to their 2019 level. Road transport accounts for 93.8% of the sector's emissions, and therefore accounts for the majority of this increase (+1. 6%). Emissions from French air transport rose by 24.9%.

International transport (sea and air), particularly concerned by the recovery from the health crisis, increased by 28% in 2022.

Between 1990 and 2022, emissions from road transport rose by 5.6% (+12.5% for heavy goods vehicles,+6. 9% for utility vehicles and+0. 7% for personal vehicles), those from French air transport by 13.9% and those from French river and sea transport by 17.7%.

GHG emission intensity of transport in metropolitan France

Note: the indicators used for passenger and freight transport are respectively GHG emissions per passenger-km transported and GHG emissions per tonne-km transported.
Scope: road (excluding utility vehicles), air, rail, sea and river transport in metropolitan France.

Transport emissions intensity corresponds to the quantity of GHGs emitted to transport one tonne of goods or one passenger over one kilometer. This indicator varies according to several factors, including modal shift (from rail to road, for example), vehicle load factor and fuel efficiency.

Since the 1990s, the GHG emissions intensity of domestic freight transport has been decreasing on a downward trend (-19% between 1990 and 2021), with a notable rebound after the economic crisis of 2008 and, to a lesser extent, after the health crisis of 2020.

Similarly, the emissions intensity of passenger transport in metropolitan France is gradually decreasing (-20% between 1990 and 2021), mainly thanks to improvements in vehicle energy efficiency. It is also rebounding after the health crisis, notably as a result of the modal shift from public transport to private vehicles.
