As recommended by the Committee on Climate Change (CCC) the government has legally committed to net zero greenhouse gas emissions by the United Kingdom by 2050 and the Energy and Climate Intelligence Unit (ECIU) has said it would be affordable. A range of techniques will be required including carbon sinks (greenhouse gas removal) in order to counterbalance emissions from agriculture and aviation. These carbon sinks might include reforestation, habitat restoration, soil carbon sequestration, bioenergy with carbon capture and storage and even direct air capture. The UK government has recently linked attainment of net zero targets as a potential mechanism for improved air quality as a co-benefit. In 2020 the UK government estimated that eliminating fossil fuels for home heating and transportation could lead to a tripling of demand for electricity.
