London Heathrow Airport was the biggest climate polluter in the United Kingdom in 2023, having released an estimated 19 million metric tons of carbon dioxide equivalent (MtCO₂e). Tata Steel's Port Talbot steel plant followed, with roughly 10 MtCO₂e emitted that year. The 10 biggest polluters in the UK were responsible for around 56 MtCO₂e in 2023, making up roughly 12 percent of the country's total emissions that year.
