Canada Sets Aside Its Boreal Forest as Giant Carbon Vault
By banning logging, mining and oil drilling in an area twice the size of California, Canada is ensuring its boreal forests continue to soak up carbon
In the far north latitudes, buried within a seemingly endless expanse of evergreen forests, the authorities in Canada are building up one of the world's best natural defences against global warming.
a series of initiatives, Canadian provincial governments and aboriginal
leaders have set aside vast tracts of coniferous woods, wetlands, and
peat. The conservation drive bans logging, mining, and oil drilling on some 250m acres - an area more than twice the size of California.
sheer scale of the forest conservation drive is somewhat of an anomaly
for Canada, whose government has been accused of sabotaging the global climate change talks by its development of the Alberta tar sands and its refusal to make deep cuts in its greenhouse gas emissions.
week, a former adviser to Barack Obama urged Canada to do more to keep
up with America's moves towards a cleaner energy economy.
latest addition to the carbon storehouse, the provincial premier of
Manitoba, Gary Doer, this month announced a $10m (£5.6m) Canadian fund
to protect a 10.8m acre expanse of boreal or evergreen forest. It was
one of Doer's last acts as premier; he took over as Canada's ambassador
to Washington this month.
The $10m will go towards efforts by
indigenous leaders to designate boreal forest lands in eastern Manitoba
as a Unesco world heritage site. The Pimachiowin Aki world heritage project,
which straddles the Manitoba-Ontario border, extends efforts by
Canadian provincial leaders to protect the wide swaths of pristine
forests in the north. It also ensures the survival of one of the best
natural defences against global warming after the world's oceans,
A report by the International Boreal Conservation Campaign
said the forests, with their rich mix of trees, wetlands, peat and
tundra, were a far bigger carbon store than scientists had realised,
soaking up 22% of the total carbon stored on the earth's land surface.
you look across Canada one of [the boreal forest's] great values to us
globally is its carbon storage value," said Steve Kallick, director of
the Pew Environment Group's International Boreal Conservation Campaign.
"There is so much carbon sequestered in it already that if it escaped
it would pose a whole new, very grave threat."
temperatures slow decomposition, allowing the build-up of organic soil
and peat. The forest floors beneath its evergreens hold twice as much
carbon per acre as tropical forests, such as the Amazon.
unclear how long Canada's forests can continue to serve as carbon
vaults. "As the climate warms, the place is going to dry up. There will
be a problem with insect infestation. There is going to be increased
natural carbon release due to fire or wetlands drying up," said Sue
Libenson, a spokeswoman for the International Boreal Conservation
But she added: "The general premise is that there is
still a hell of a lot of carbon in there." Its release would be a
Canada's 1.3bn acres of boreal forest store the equivalent of 27 years' worth of current global greenhouse gas emissions, a Greenpeace study
found. The destruction of those forests, scientists warn, would be like
setting off a massive "carbon bomb" because of the sudden release of
That threat appears to have concentrated the official
mindset in Canada, which otherwise has a poor record on action on
climate change. On a per capita basis, the country is one of the worst polluters on the planet, producing about 2% of the world's emissions even though it has just 33m people. It holds one of the worst track records
among industrialised states for living up to its commitment under the
Kyoto accords. By 2007, greenhouse gas emissions were 34% above the
target Canada agreed at Kyoto.
Canada's prime minister, Stephen
Harper, is resisting doing much more, committing to just a 6% cut over
1990 levels of greenhouse gas emissions by 2020. "I see Harper's policy
as a continuation of the Bush agenda," said David Martin, climate
director for Greenpeace Canada.
key advisor to Obama made a similar point last week, comparing Canada's
current climate change policy to the inaction in America under George
Bush. "The Canadians would be well served by keeping up with what's
going on in the United States with respect to this push towards clean
technology," John Podesta, who oversaw Obama's transition team, told a
conference in Ottawa.
Environmentalists also fear that Harper
intends to exclude the Alberta tar sands - the heavy crude deposits
that have fuelled the rise in emissions - from any future greenhouse
gas emissions regime.
But the Harper government did relent on
forest protection, working with the Sahtu and Deh Cho First Nations to
set aside 40m acres in the Northwest Territories.
provincial leaders have moved even more aggressively in recent years,
with Ontario committed to protecting 55m acres, or about half of its
forest, and Quebec committed to protecting 150m acres. "Canada is torn
between wanting to promote the tar sands and make money off it now, and
wanting to live up to its promises under the Kyoto accord. But as far
as protecting carbon rich ecosystems, particularly the boreal forest,
Canada is a world leader," said Kallick.
