Not surprisingly, researchers have concluded that trees are the most effective technology for removing carbon dioxide from the atmosphere and reversing global warming.

An article in Bloomberg Business reports that scientists from Oxford University have spent a year investigating other ‘Negative Emissions Technologies’ (NETs) such as capturing emissions from factories and power stations, extracting carbon dioxide directly from the air and adding lime to oceans to increase their absorption of carbon dioxide.

Planting trees (afforestation) and biochar were found to be low-cost, have fewer uncertainties and offer other benefits to the environment compared to other NETs.

The scientists have suggested that post 2050 other NETs may have more potential and investments should still be made in them in case they are needed.
