A report released Wednesday by the MTI found that one billion tons of carbon dioxide must be removed from the atmosphere by 2025 to avoid catastrophic warming. At the 2015 Paris Climate Summit, more than 190 countries signed a cap on limiting global warming to 1.5°C above pre-industrial average temperatures. However, many scientists believe that in addition to promises to reduce greenhouse gas emissions, carbon capture technologies are also needed.
If one gigatonne of carbon dioxide could not be extracted, then 1.5 degree climate steel would not be achieved.
Stands in the latest report from the Coalition for Negative Emissions (CNE) and consulting firm McKinsley. According to researchers
- billion tons of carbon dioxide by 2025,
- Then more than a billion a year
It must be removed from the atmosphere.
Projects currently under development will be enough to remove about 150 million tons of carbon dioxide by 2025, a fraction of what is needed.
The report warns.
So-called negative emissions projects include bioenergy plans to capture and store the carbon dioxide emitted, technologies to directly extract carbon dioxide from the air, and natural solutions such as afforestation. Existing technologies are expensive, but the report says that developing and expanding the technologies would lead to lower costs. The average cost per ton is likely to reach 41-138 dollars (12-40 thousand fort) by 2050.
