- The target was statutory, meaning it had been set in law in the Emissions Reduction Targets Act of 2019.
- Scotland is still subject to the 2030 carbon target for the UK as a whole.
- The consistent implementation of the existing targets, in other words, is the difference between meeting the Paris objectives and condemning the planet to dangerous climate change.
Legally (but not literally) binding
- In 2017, Sweden was the first major economy to enact a statutory net zero target.
- Its net zero target is complemented by a series of intermediate steps: five-yearly carbon budgets, which are also legally binding.
- Legal scholars have long known that, even though the targets are legally binding, they would be difficult to enforce against an unwilling government.
Governments in the dock
- The plaintiff was the environmental law charity ClientEarth, which remains dissatisfied with the strategy and returned to court in February 2024.
- If successful, such a move would be the latest in a series of court cases in which judges have ordered governments to scale up their climate ambitions.
- The political embarrassment of missing a statutory target, or being subject to a court case, can focus the mind.
- A review of the UK Climate Change Act found that civil servants were petrified about the threat of a judicial review.
- Scotland’s decision to abandon its 2030 climate ambition is the most brazen violation of a statutory climate target yet.
