Research shows if and when markets can help limit the harms from climate change. Even under the most ambitious greenhouse gas emissions mitigation scenarios, climate change will continue to affect human well-being for generations, with the severity of these impacts differing across mitigation pathways. Adapting to climate change is thus a necessary complement to mitigation. Because individuals, businesses, and communities benefit directly from their adaptation choices, the incentives they face as individuals to adapt are generally stronger than the incentives they face to mitigate emissions. Yet evidence to date suggests that communities are not systematically adapting to recent climate changes (1). What can policy-makers do to facilitate adaptation? Here, we draw on a burgeoning field of economic research on climate adaptation to identify when and how markets can be a promising tool for effective and efficient adaptation.

Ecosystem services are often omitted from climate policy owing to difficulties in estimating the economic value of climate-driven ecosystem changes. However, recent advances in data and methods can help us overcome these challenges and move towards a more comprehensive accounting of climate impacts.
