Road transportation emissions in the United Kingdom reached almost 100 million metric tons of carbon dioxide equivalent (MtCO₂e) in 2023. Emissions from road vehicles dropped nearly 20 percent in 2020 due to the outbreak of COVID-19 and the resulting restrictions. While emissions rebounded in 2021 and 2022, figures were still well below pre-pandemic levels. Passenger cars are responsible for the largest share of transportation emissions in the UK, accounting for more than 50 percent.
