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 the oil and gas industry. These early moves could create global spillovers for follower countries by reducing technology cost and facilitating knowledge transfer through global firms.
