<p>The Government has not made this comparison itself. The legislation that Parliament
passed to achieve net zero greenhouse gas emissions in the UK by 2050 is aligned with
advice from our independent Committee on Climate Change, and is based on evidence
regarding global emissions provided by the Intergovernmental Panel on Climate Change’s
Special Report on the impact of 1.5°C global warming.</p><p> </p><p>The evidence shows
that in order to limit global warming to 1.5°C, global emissions of carbon dioxide
must roughly halve by 2030 and reach net zero by around 2050. The UK’s net zero target
is for all greenhouse gases which goes beyond this global pathway to 1.5°C. Delivering
this target will require ambitious action across government and this commitment puts
us in a strong position to call for other countries to follow our lead and consider
what similar commitments they can make.</p>
