Abstract:
Despite growing efforts to drastically cut carbon dioxide (CO2) emissions and address climate change, energy outlooks project that the world will continue to rely on certain products that are currently carbon-intensive to produce but have limited alternatives, such as aviation fuels and concrete. Recycling CO2 into valuable chemicals, fuels, and materials has emerged as an opportunity to reduce the emissions of these products. In this way, CO2 recycling is a potential cornerstone of a circular carbon economy that can support a net-zero future. However, CO2 recycling processes have largely remained costly and difficult to deploy, underscoring the need for supportive policies informed by analysis of the current state and future challenges of CO2 recycling. This report, part of the Carbon Management Research Initiative at Columbia University’s Center on Global Policy, examines 19 CO2 recycling pathways to understand the opportunities and the technical and economic limits of CO2 recycling products gaining market entry and reaching global scale. The pathways studied consume renewable (low-carbon) electricity and use chemical feedstocks derived from electrochemical pathways powered by renewable energy. Across these CO2 recycling pathways, the authors evaluated current globally representative production costs, sensitivities to cost drivers, carbon abatement potential, critical infrastructure and feedstock needs, and the effect of subsidies. Based on this analysis, the paper concludes with targeted policy recommendations to support CO2 recycling innovation and deployment.

Abstract:
The case for rapid and profound decarbonization has never been more obvious or more urgent, and immediate action must match growing global ambition and need. An important new component of this discussion is the necessity of achieving net-zero global greenhouse gas emissions for any climate stabilization target. Until net-zero emissions are achieved, greenhouse gas will accumulate in the atmosphere and oceans, and concentrations will grow, even with deep and profound emissions reduction, mitigation, and adaptation measures. This places a severe constraint on human enterprise: any carbon removed from the earth must be returned to the earth.
