- In addition to reducing GHG emissions, carbon dioxide removal (CDR) techniques play a crucial role in mitigating climate change
Strategies for Carbon Dioxide Removal
| Removal Strategy |
Description |
| Protecting and Enhancing Carbon Sinks through Land Management |
- Implementing programs like the UN Collaborative Programme on Reducing Emissions from Deforestation and Forest Degradation in Developing Countries (UNREDD) to prevent deforestation and promote sustainable forest management
- Restoring and expanding forests through afforestation and reforestation initiatives, which absorb carbon dioxide through photosynthesis
- Implementing sustainable land management practices such as agroforestry and soil carbon sequestration (sometimes referred to as “carbon farming” or “regenerative agriculture”) to enhance carbon sinks in agricultural landscapes
|
| Using Carbon Capture and Storage (CCS) |
- Capturing carbon dioxide emissions from industrial facilities, power plants, and other large-scale sources before they are released into the atmosphere
- Transporting the captured carbon dioxide and securely storing it underground or utilising it for industrial purposes
|
| Using Biomass as a Fuel Source |
- Utilising bioenergy with carbon capture and storage (BECCS) technology, which involves capturing carbon dioxide emissions from biomass combustion and storing it underground, effectively removing carbon dioxide from the atmosphere
- Promoting sustainable cultivation of bioenergy crops that does not cause deforestation - bioenergy crops absorb carbon dioxide from the atmosphere as they photosynthesise
|
| Enhancing Carbon Dioxide Absorption by the Oceans |
- Exploring ocean fertilisation techniques by adding compounds like nitrogen, phosphorus, and iron to stimulate the growth of phytoplankton, which absorb carbon dioxide through photosynthesis
- Investigating methods to increase upwellings, which bring nutrient-rich deep waters to the surface, with the same effect of promoting the growth of phytoplankton and enhancing carbon dioxide absorption
