Negative CO2 emissions

As CO2 emissions may not be reduced quickly enough, technologies are being developed to mitigate past emissions.

Various technologies aimed at removing carbon dioxide from the atmosphere have received increased funding. These technologies include systems similar to those used for CO2 removal in Navy submarines, as well as methods for absorbing CO2 through reforestation in arid regions with minimal irrigation. Another approach involves cultivating plants, burning them to generate energy, and then capturing the resulting CO2 for underground storage.

This technology could also be applied to “clean coal” initiatives, allowing existing coal plants to capture and store CO2 emissions, thus reducing their environmental impact.
