As nations plan to reduce the greenhouse gas emissions from fossil fuel combustion, an international team of scientists has calculated just how much the natural and farmed world could contribute to future stability by absorbing ever more carbon dioxide. The answer: up to 30 percent more than anyone had first thought. Natural climate solutions—a way of saving protected forests, conserved marshlands and carefully managed farmland and pasture—could deliver 37 percent of the carbon mitigation needed by 2030. Should countries act on this research, it would significantly boost chances of reaching the Paris climate targets.
