An international study has found that natural solutions to mitigate climate change, such as reforestation, could have the same effect globally as taking 1.5 billion cars off the road. The top three land management solutions identified that reforestation, avoiding further forest losses and improved forestry practices could cost-effectively remove seven billion tonnes of carbon dioxide (CO2) from the atmosphere annually. CSIRO collaborated with The Nature Conservancy and 14 other institutions in the study published in the Proceedings of the National Academy of Sciences.
