greenhouse gas removal
innovation in greenhouse gas removal
Reaching net-zero emissions may require neutralizing a company’s residual GHG emissions with an equivalent amount of carbon removals. An effective neutralization strategy involves removing carbon from the atmosphere and storing it for a long-enough period to fully neutralize the impact of any GHG that continues to be released into the atmosphere.
Approximately 12 Gigatonnes of carbon dioxide will need to be removed globally per year by 2100, to tally with the IPCC scenarios that have greater than 66% chance of limiting global warming to 1.5°C. To meet the 2°C goals of the Paris Agreement requires rapid and dramatic decreases in emissions, but also active removal of greenhouse gases from the atmosphere, commencing in the next decade.
Greenhouse Gas Removal (GGR, also known as negative emissions) encompasses a range of techniques for reducing the concentration of greenhouse gases in ambient air. While there are some proposed methods for removing greenhouse gases other than CO2, the vast majority of GGR methods are CO2-based. CO2 removal involves two main steps;
- The capture of CO2 from the atmosphere
- Storage for long periods, which can be in land-based biomass, subsurface geological formations, the oceans, or the built environment.

ggr removal technologies
There are various types of Greenhouse Gas Removal (GGR) technologies which recapture already emitted greenhouse gases from the atmosphere and ocean.
Nature-based Solutions (NBS) work with and enhance nature to help achieve Green House Gas Removal. These solutions prevent climate change impacts while slowing further warming.
The Need for Collaboration
Innovation depends on collaboration, often between unlikely partners, and it often involves the adaptation and application of technologies from other industries.
