Net zero is a statutory target for at least a 100% reduction of UK greenhouse gas emissions by 2050 (compared to 1990 levels). It replaced the UK’s previous target to reduce emissions by 80% by 2050. The aim is to reduce greenhouse gas emission as much as possible but it is known as a net zero target because some emissions can remain provided they are offset (i.e. by removal from the atmosphere and/or by trading in carbon units). If met, this target would effectively mean the UK would end its contribution to global emissions by 2050.
A net zero company, as defined by the Carbon Trust, will set and pursue an ambitious 1.5°C aligned Science Based Target for its full value chain emissions. Any remaining hard-to-decarbonise emissions can be compensated with certified greenhouse gas removal (GGR).
