Transboundary climate risks: An overview

The impacts of climate change are not confined or experienced only nationally: they impact international trade and supply chains, capital flows, human mobility and natural resources shared between countries, regionally and globally. Likewise, actions to adapt to the impacts of climate change can have effects far beyond the jurisdiction of the government implementing them. The consequences of climate change, and the measures governments take to respond to them, are sub-national and national policy problems – but they also transcend national boundaries, and call for a multilateral response that current approaches to climate change adaptation cannot provide.
