This paper finds that for a CCU technology to be Paris Agreement compatible by 2030, it has to have low GHG emissions from CO2 capture and conversion, replace a GHG-intensive substitute, and in most cases lead to permanent storage.
Fair distributions of carbon dioxide removal obligations and implications for effective national net-zero targets
This paper looks at the implications that an equity perspective could have on national and regional obligations for negative emissions and the respective timings of net-zero targets.
This article identifies how the deployment of enhanced rock weathering within existing croplands offers opportunities to align agriculture and climate policy, while needing to overcome political inertia to develop regulatory and incentive frameworks.
This paper reviews the role of Article 6 of the Paris Agreement in enabling countries to meet the objectives they have set themselves in their Nationally Determined Contributions (NDCs), with particular emphasis on how it can impact CCS.
A declaration by Finland, Iceland, Sweden, Norway and Denmark to catalyze the development of technologies that reduce greenhouse gas emissions, remove carbon dioxide from the atmosphere, and to maintain or enhance natural carbon sinks.
Direct Air Carbon Capture and Sequestration: How It Works and How It Could Contribute to Climate-Change Mitigation
The paper discusses the role of Direct Air Capture in meeting the Paris Agreement, while noting the ecological and ethical considerations, and the potential trade-offs and uncertainties that deserve further investigation.
This Policy Brief assesses 18 ocean-based measures, including some carbon dioxide removal techniques, to support climate policies and the revision of National Determined Contributions (NDCs) in the areas of mitigation and adaptation.
This paper suggests that improved recognition of different land-system policies and lags in land-system change is necessary to identify achievable mitigation actions and avoid excessively optimistic assumptions and consequent policy failures.
