Negative emission strategies are central to avoiding catastrophic climate change.
Engineered solutions such as direct air capture are far from cost-competitive. As past low-
carbon technology transitions suggest, this calls for policy and political strategies beyond
carbon pricing. We adopt a policy sequencing perspective that identifies policies that could
create niche markets, building political support for later widespread deployment of direct air
capture. Climate leaders could pursue an “incentives+ mandates” policy strategy targeted at …
