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.

Canada could achieve just over one-tenth 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.
The researchers from universities, governments and environmental groups say a good portion of those emissions cuts could be made for under $50 a tonne, less than next year s carbon tax.
Natural climate solutions are relatively cost-effective ways to mitigate greenhouse gas emissions, said Amanda Reed, who co-ordinated the research for Nature United, the Canadian affiliate of The Nature Conservancy.
Grassland soils, peat-rich wetlands and old-growth forests store large amounts of carbon, said Reed. But they could store even more if Canadians farmed, logged and developed differently.
The report says agriculture offers the biggest chance for carbon savings.
At current rates, about 2.5 million hectares of native grassland are expected to be converted to crops by 2030. Cultivation releases carbon from the soil into the air.
Preventing that would keep almost 13 million tonnes of carbon in the ground, the report says. About 13 per cent of those savings could be accomplished for less than $50 a tonne.
