In this article, Ecologic Institute's Lena Donat and Ralph Bodle provide a structured approach for developing and evaluating options for a dynamic adjustment mechanism in the 2015 climate agreement. To ensure that the 2015 Agreement, that is currently being negotiated under the United Nations Framework Convention on Climate Change (UNFCCC), provides an effective response to climate change over time, it needs to encorporate flexible and dynamic elements. This should include a possibility for Parties to regularly adjust their mitigation commitments so as to increase the level of ambition and to reflect changing circumstances.

The article explores design options for such a dynamic adjustment mechanism and provides possibilities for trigger, process, consequences and derogations. It draws from previous experience under the UNFCCC and under other multilateral environmental agreements, as well as from literature.
