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, written in collaboration with the U.S. House of Representatives Science and Technology Committee, examines the need for the regulation of geoengineering activities and provides an outlines of future regulatory arrangements.
This report examines the state of geoengineering science, federal involvement in geoengineering, the extent to which federal laws and international agreements apply to geoengineering, and any governance challenges around geoengineering activities.
This article provides a comparative analyses whether biochar is waste in the EU and the US and whether the pyrolysis treatment, transportation and storage of biochar may be exempted from the regulatory burden placed on the classification of waste.
This paper explores how small-scale biochar systems with net emission reductions may hold a key for Africa to engage with the international offset mechanisms and open the door to soil carbon sequestration projects.

This article examines the economic potential of ocean iron fertilization in the context of a post-Kyoto Protocol climate agreement and what public international law says, and should say, on the issue of ocean iron fertilization.
This is an article from the International Environmental Law Committee newsletter that provides an overview of the legal posture of ocean iron fertilization (OIF) activities under international environmental law.
This paper summarizes proposals for climate related geoengineering projects that involve or affect the ocean and reviews the applicable legally binding global instruments that seek to regulate these activities.
