The United Kingdom (UK) government is proposing to amend its target of reducing greenhouse gas emissions by 80% by 2050, which was agreed to under the Climate Change Act in 2008, to achieving net zero emissions by 2050. The net zero target was recommended last month by the government's advisory Committee on Climate Change. According to the committee, there is a 50-50 chance of staying below the recommended 1.5°C temperature rise by 2100 if the UK and other countries achieve the target.
