While many who are concerned with climate change are working to reduce the amount that is produced, some scientists are working the other end of the equation—how to remove the CO2 that is already in the atmosphere. Plants are natural CO2 scrubbers changing sunlight water and CO2 into sugar and oxygen. Now scientists have made a synthetic leaf made of Copper Oxide that converts sunlight, water and CO2 into oxygen and methanol. This new kind of technology can be embedded into resins that could coat synthetic trees. The new method removes 100 times more CO2 than a regular plant leaf and the methanol byproduct can be used as a fuel.
