However, the use of these appropriations should not increase the total number beyond 50% of the necessary reductions. Such agreements would not be necessary for new projects launched in the least developed countries from 2013 on or after 2013.

In order to avoid such a risk, Member States may grant compensation for those costs. In the absence of an international agreement on climate change, the Commission has undertaken to amend the Community guidelines on State aid for environmental protection in this regard.
