In 2007, Prime Minister Stephen Harper’s government asked me
and four other economists if we agreed with its study showing huge costs for
Canada to meet its Kyoto commitment to reduce greenhouse gas emissions by 2010.
We all publicly agreed, much to the chagrin of the Liberals, NDP and Greens,
who argued that Kyoto was still achievable without crashing the economy. It
wasn’t.
As economists, we knew that the Liberal government of Jean
Chrétien should have implemented effective policies right after signing Kyoto
in 1997. It takes at least a decade to significantly reduce emissions via
energy efficiency, switching to renewables, and perhaps capturing carbon
dioxide from coal plants and oil sands. Each year of delay jacks up costs.
Mr. Harper’s government knew this too. Years later, when
environment minister Peter Kent formally withdrew Canada from Kyoto, he charged
the previous Liberal government with “incompetence” for not enacting necessary
policies in time to meet their target.
