The Paris Agreement recognizes adaptation to climate change as a “global challenge faced by all, with local, sub-national, national, regional and international dimensions”, and a key component of the global response needed to protect people, livelihoods and ecosystems.
Article 7 of the agreement thus sets a global goal on adaptation, and calls for international cooperation and support to enhance adaptation action. Within countries, it encourages the development of national adaptation plans and priorities for action, as well as periodic adaptation communications under the United Nations Framework Convention on Climate Change (UNFCCC).
The language of the Paris Agreement reflects a growing understanding that while the physical impacts of climate change are location-specific, in a globalized world, people and countries are increasingly connected. This means adaptation is ultimately a collective endeavour: we are all in this together.
Applying this insight to adaptation planning requires a new lens through which to view climate impacts and adaptation responses. This policy brief, which builds on an SEI Working Paper published earlier this year, introduces a framework for quantitative assessment of country-level exposure to what we call the transnational impacts of climate change.
Transnational climate impacts reach across borders, affecting one country – and requiring adaptation there – as a result of climate change or climate-induced extreme events in another country. We have used our analytical framework to develop nine indicators of country-level exposure and a composite index: the Transnational Climate Impacts (TCI) Index.
This brief explains how the indicators and the TCI Index were developed, describes some of the results, and offers reflections on the implications for both national adaptation planning, and global cooperation on adaptation under the UNFCCC.
