Rooftop photovoltaic systems are often seen as a niche solution for mitigation but could offer large-scale opportunities. Using multi-source geospatial data and artificial intelligence techniques, the authors map their potential for reducing global temperatures and analyse regional differences.

Responsible carbon dioxide removal governance requires engagement with stakeholders, who have various agendas, positions and interactions in the socio-technical landscape. This Perspective discusses stakeholder heterogeneity and recommends approaches to characterize and navigate their relationships.

Discourse on carbon dioxide removal on social media has become positive over time, except for bioenergy with carbon capture and storage, with 31 percent of tweets from infrequent users, which make up 78 percent of all users, according to an analysis of Twitter (now X) data from 2010 to 2022.

A feasibility analysis reveals that carbon capture and storage capacity might be able to expand fast enough to meet the requirements of 2 °C climate pathways but will unlikely meet those for 1.5 °C. Moreover, carbon capture and storage is unlikely to capture and store more than 600 Gt of CO₂ over the twenty-first century, which has implications for the global carbon budget.

Technological feasibility and project-level economic costs are only two important considerations in previous estimations of climate mitigation costs. Now a study shows how political and institutional constraints matter too.

Recent policy progress in the United States shows how populism can help advance climate goals, but at a steep cost. Avoiding setbacks will require curbing protectionist reflexes and harnessing opportunities for global cooperation.

Policies and subsidies can help, and have helped, to establish the electric vehicle market. As subsidies are withdrawn and policies shift, the public will play a role in the future market infiltration.
