Section 17: Powers to carry amounts from one budgetary period to another
87.This section provides a power for the Secretary of State to “bank” and “borrow” emissions between budgetary periods.
88.Subsection (1) allows the Secretary of State to “borrow” part of the next budget. In the language of the Act, an amount from the next budget is “carried back” to the budget preceding it. Where this power is used, the next budget (which will already have been set by order) is reduced by the amount that has been borrowed.
89.Subsection (2) limits the amount that can be borrowed under subsection (1) to no more than 1% of the next budget.
90.Subsection (3) allows the Secretary of State to carry forward any part of the carbon budget that exceeds the net UK carbon account for that period (i.e. to “bank” a budget surplus, but not necessarily all of it). The banked amount is added to the next budget.
91.Subsection (4) requires the Secretary of State to obtain the advice of the Committee on Climate Change, and take this advice into account, before exercising powers under this section (that is, before banking or borrowing). The Secretary of State is also obliged to consult the devolved administrations before banking or borrowing.
92.Subsection (5) places a back-stop on when the banking and borrowing powers can be used. A decision to bank or borrow must be taken no later than 31st May in the second year after the earlier budget period ends (so, for the 2008–2012 budget, no later than 31st May 2014). This is also the date on which a assessment is made of whether the budget has been met (see section 18).
