Reforestation to capture carbon could be done much more cheaply, study says

  By Liz Kimbrough, via Mongabay   Trees are allies in the struggle against climate change, and regrowing forests to capture carbon may be cheaper than we thought. According to new research published in Nature Climate Change, a strategic mix of natural regrowth and tree planting could be the most cost-effective way to capture carbon. Researchers analyzed reforestation projects in 138 low- and middle-income countries to compare the costs of different […]

By Claire Asher via MongaBay As the world grapples with escalating climate change, policymakers remain laser-focused on CO2, with humanity striving to decarbonize energy systems, capture carbon, issue carbon credits, and plant millions of trees to absorb emissions. But carbon dioxide is just one of several powerful greenhouse gases destabilizing the global climate, and just one of the human-produced pollutants severely impacting the natural world and threatening to push Earth out […]
