"Zero carbon sooner" CO2 budget report from CUSP

This is a commentary on a report on the UK's CO2 budget titled Zero carbon sooner by Prof Tim Jackson of the Centre for the Understanding of Sustainable Proposperity (CUSP) at the University of Surrey.

It was published in 2021 following the publication of the IPCC's AR6 WG1 report.

The main points are that
  • the UK Government's timescale of cuts in CO2 emissions is grossly inadequate
  • instead, to meet the UK's international commitments, immediate radical emission cuts of over 20% annually are needed.
