Technology for sustainability: Carbon capture

Carbon capture can be divided into two main categories: first, the extraction of CO2 from waste streams, such as after combustion in power generation. This helps decrease the amount of CO2 released into the atmosphere. And second, direct air capture, which involves removing CO2 directly from the atmosphere. This helps reduce the current concentration of CO2 in the atmosphere. 

Both methods are crucial for achieving a 1.5°C pathway for the climate because the existing CO2 levels are excessively high.
