Capturing CO₂ from air

Abstract

Schellnhuber proposed some well-known solutions to the climate problem:

•i) Phasing out of CO₂ in the next decades;

•ii) Energy efficiency;

•iii) Emission reduction;

•iv) Systematic decarbonation;

•v) Efficiency and renewables.

These suggestions are commendable, but their suggested time scheme lacks realism. The emerging economies (China, India, and Brazil) want to develop their economies and raise the standard of living. A prerequisite is access to abundant and cheap energy. They want to realize their objectives by using their large coal reserves.
