On 1 May 2019, the UK Parliament declared a climate emergency. Also in In May 2019 the Uk Committee on Climate Change published the Net Zero the UK’s contribution to stopping global warming.
This report recommended a new emissions target for the UK: net-zero greenhouse gases by 2050. The report said this “Our recommendation emerges clearly from the extensive evidence presented here for the first time. We have reviewed the latest scientific evidence on climate change, including last year’s IPCC Special Report on Global Warming of 1.5°C, and considered the appropriate role of the UK in the global challenge to limit future temperature increases.”
It goes on to describe the potential to achieve deep emissions reduction in the UK and presents an appraisal of the costs and benefits to the UK economy of doing so.
It concludes that “net-zero” is necessary, feasible and cost-effective.
The report was accepted by both UK and Scottish governments who went on to set the commitment to netzero in statute.
