Mitigation refers to efforts aimed at preventing or slowing the progression of climate change by reducing greenhouse gas emissions at their source. This includes transitioning to renewable energy, improving energy efficiency, changing land use practices, and implementing carbon pricing policies. The ultimate goal of mitigation is to limit the extent of global warming and reduce the risk of severe environmental and societal impacts.
**Geoengineering** is an emerging and controversial field that involves large-scale technological interventions in the Earth’s climate system. Its purpose is to counteract or manage the effects of climate change, particularly when mitigation alone is insufficient. Geoengineering is typically divided into two main categories: **solar radiation management (SRM)**, which aims to reflect a portion of sunlight back into space to cool the planet, and **carbon dioxide removal (CDR)**, which focuses on extracting CO₂ from the atmosphere. While potentially powerful, many geoengineering techniques carry significant risks and ethical concerns.
**Drawdown** refers to the point at which greenhouse gas concentrations in the atmosphere begin to decline year-over-year, marking a reversal of the buildup driving global warming. Achieving drawdown requires both stopping new emissions and actively removing existing carbon from the air and oceans.
**Carbon Capture and Sequestration (CCS)** involves capturing CO₂ from power plants, industrial facilities, or directly from the atmosphere, and then storing it underground or using it in industrial processes. Other approaches include afforestation, biochar, soil carbon enhancement, and ocean-based carbon removal.
**Interest in CCS should be considered alongside a review of the “Carbon in Our Biosphere for 1,000 Generations” section of the Overshoot page.**
**Project Drawdown’s mission is to help the world stop climate change by advancing effective, science-based climate solutions and strategies; fostering bold, new climate leadership; and promoting new climate narratives and new voices.**
