The U.K. said it’s delaying for as many as four years a decision on whether to include greenhouse gases from international aviation and shipping in its five-year carbon budgets, which set a ceiling on national emissions.
Energy Secretary Ed Davey today cited “uncertainty” over international rules to reduce emissions from planes and ships that cross boundaries when deferring the decision, which had been due by the end of 2012.
The government “will revisit this issue when setting the fifth carbon budget,” Davey said today in a statement posted on Parliament’s website.
The fifth carbon budget, capping U.K. emissions for the five years from 2028 through 2032, is due to be set in 2016. Domestic aviation and shipping are already included in the budgets.
