Carbon dioxide removal (CDR) techniques, or negative emission technologies (NETs), are a suite of natural and technological pathways to remove and sequester carbon dioxide (CO₂) from the air. Unlike carbon capture and storage, these techniques remove CO₂ directly from the atmosphere or enhance natural carbon sinks.

This report describes the background, methodology, and implementation processes which led to the success of the National Reforestation Programme in the Republic of Korea.
Philadelphia’s Parks and Recreation has adopted a comprehensive parkland forest management plan that expressly recognizes the value of carbon sequestered in the city's green spaces and adopts management programs to sequester additional carbon.
This paper reviews existing scientific evidence from a European policy perspective and identifies research gaps for future comprehensive assessments of the policy, environmental, economic, and health implications of the systematic use of biochar.
