Section 18 of the Climate Change Act requires that a final statement is laid before Parliament in respect of each budgetary period.
The statement for the second budgetary period covering 2013 to 2017 shows that:
over the second budgetary period, UK emissions as calculated by the net UK carbon account were 2,398 million tonnes of carbon dioxide equivalent (MtCO2e)
this is 384 MtCO2e below the second carbon budget cap of 2,782 MtCO2e
on average this means emissions as measured by the net carbon account were 40% lower than 1990 base year emissions over the second carbon budget period
