Breakdown of greenhouse gas emissions in the UK 2021, by sector
The transportation sector is the primary source of greenhouse gas emissions in the United Kingdom. In 2021, net greenhouse gas emissions in the UK totaled 426.5 million metric tons of carbon dioxide equivalent (MtCO2e), of which roughly one quarter was attributable to transportation. Passenger car emissions are by far the biggest contributor to transportation emissions.
The energy supply sector was the most polluting sector in the UK in previous years, but emissions from this sector have fallen dramatically as the country shifts away from coal and transitions to cleaner energy sources.
