Canada could reach one-third of its greenhouse gas reduction targets by making better use of its vast forests, prairies and wetlands, says a report by more than three dozen scientists.

“Natural climate solutions are relatively cost-effective ways to mitigate greenhouse gas emissions,” said Amanda Reed, who co-ordinated the research for Nature
