Climate change: UK government to commit to 2050 target

Britain’s existing target is to cut greenhouse gas emissions by 80 percent from 1990 levels by 2050. The new target is in line with the 2015 Paris climate agreement which calls on countries to reduce carbon emissions to net zero by mid-century to try to keep the global temperature rise as close to 1.5 degrees Celsius as possible.

Temperatures have already risen about one degree Celsius since pre-industrial times. Scientists warn further increases risk triggering tipping points that could render swathes of the globe uninhabitable, devastate farming and drown coastal cities.
