ABSTRACT

It is essential to reach net zero GHG emissions. Various methods have been proposed to remove carbon dioxide from the atmosphere. Carbon dioxide removal (CDR) is complemental to dramatic reduction in anthropogenic emissions of greenhouse gases (GHG) from fossil fuel burning, other industrial processes, and land management practices. This chapter introduces basic concepts of CDR, briefly describes land-based CDR, and outlines biogeochemical principles for evaluation and design of CDR strategies.
