In 2019, the United Kingdom passed the net zero emissions law which requires all greenhouse gas emissions to be reduced to net zero by 2050. 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.
