What Sunak claims about the UK's climate record and the reality
The UK has decarbonized faster than other major economies in the past, but recent data shows Germany cutting emissions faster since the Paris agreement.
The UK is the 13th largest climate donor in the world, but as a top economy, it could do better.
The UK's rollback on net zero targets will make it more difficult to meet carbon targets, contrary to Sunak's claims.
The claim about families saving thousands of pounds with the rollback is debatable, as there were always exemptions for those unable to switch to heat pumps.
