The impacts of climate change experienced in the UK in the 21st century are both social and environmental. While both impacts are significant, the social impacts are arguably greater. For example, in 2019 the UK introduced the Ultra Low Emission Zone (ULEZ) in London, which has had a significant social impact on the city. The ULEZ has increased the cost of operating vehicles in the city, with the intention of reducing emissions. This has had a significant impact on the social dynamics of the city, with many low-income households feeling the financial burden of the ULEZ. Additionally, the ULEZ has led to an increase in public transport use, which has had a knock-on effect on many businesses and services that rely on car use. These social impacts are arguably more significant than the environmental impacts, as the ULEZ has only had a limited effect on reducing emissions. Therefore, it can be argued that the social impacts of climate change experienced in the UK in the 21st century are greater than the environmental impacts.
