UK: the first country to set legally binding carbon budgets
'A carbon budget places a restriction on the total amount of greenhouse gases the UK can emit over a 5-year period. The UK is the first country to set legally binding carbon budgets.
Under a system of carbon budgets, every tonne of greenhouse gases emitted between now and 2050 will count. Where emissions rise in one sector, the UK will have to achieve corresponding falls in another.'
The carbon budgets are introduced to help the UK reduce greenhouse gas emissions by at least 80% by 2050.
