The Carbon Budget Order 2016 sets the carbon budget for the 2028-2032 budgetary period as 1,725,000,000 tonnes of carbon dioxide equivalent (including emissions from international shipping). The budget limits annual emissions to an average 57 per cent below 1990 levels.
Carbon budgets set a cap on the maximum level of the net UK carbon account for each five-year budgetary period. The net UK carbon account is defined in section 27 of the Climate Change Act 2008.
