Clear targets and a transparent framework has improved
public and business engagement.

•

Legal obligation on specific Minister ensures climatechange has high profile in Government.

•An evidence-led independent advisor has helped resolve
political differences.

•The Net Zero Target has focussed minds (no ‘free’ 20%).

“The CCC has had a strong
influence on UK climate policy.
Its analysis is used and trusted
by stakeholders on all sides ofthe debate, and its statutory
advice has generally been
followed.” London School ofEconomics - Grantham
Research Institute on the role of
the CCC (2018)9Advice on the path toNet ZeroSetting the path to Net Zero – an approach defined by the Climate Act
