When intensity is stupidity
Suzuki says plans to cut emissions shouldn’t be based on relative targets
David Suzuki
Ever since the media have finally decided that global
warming is front-page material, politicians have been scrambling
to come up with ways to placate an increasingly concerned
public.
Some of those ways are brave, forward-thinking and innovative. Some are complete
bunk. Being able to tell the difference is critical to making an informed decision.
Of course, what I just said is a gross simplification. Global warming is a pretty
complicated subject, so the issue can be tackled in a variety of ways.
However, when it comes right down to it, the ultimate goal must be to truly reduce
heat-trapping greenhouse-gas emissions. That’s the cause of the problem.
If you don’t actually reduce those emissions in absolute terms, then the
problem will keep getting worse and your plan won’t be worth the paper
on which it is printed.
And this is where the trouble begins. One type of plan, in theory to reduce global
warming, involves something called “intensity” targets. A smiling
politician will often stand up and proudly proclaim new intensity-based greenhouse-gas
targets as the foundation of that government’s plan to fight global warming.
Unfortunately, intensity-based targets will do no such thing. Greenhouse-gas
intensity refers to the amount of greenhouse gases produced per unit of economic
activity (GDP, for example). Right away, you can likely see the problem with
such a plan. If targets are tied to economic growth, then actual greenhouse-gas
emissions can continue to rise so long as they decrease relative to economic
expansion.
Here’s an example: Between 1990 and 2004, Canada’s industries reduced
their greenhouse-gas emissions intensity by six per cent. Fantastic! Based on
this approach we appear to be well on our way to solving the problem. Well, not
so fast. Because the economy grew so much during that period, Canadian industry’s
actual emissions grew by 13 per cent.
So even if intensity-based targets seem to call for a reduction in emissions,
actual emissions could very well continue to rise. In fact, combined with policies
that encourage economic growth, they most certainly will increase. And because
the atmosphere does not respond to intensity but rather to actual greenhouse
emissions, such targets will do little, if anything, to fix the problem. Based
on Canada’s own experiences, they could just put us further and further
behind.
Yet many politicians love intensity-based targets — because industries
love them. Such targets enable them to have their proverbial cake and eat it,
too. They appear to be reducing pollution while actually expanding and polluting
even more. U.S. President George W. Bush favours intensity targets — as
did former Alberta premier Ralph Klein.
Canada’s only current national plan to tackle global warming — the
Clean Air Act — also uses intensity-based targets up until at least 2020.
That act, also called bill C-30, recently underwent an all-party committee review.
It was substantially revised and now includes real targets — a step in
the right direction. Whether Canada proceeds with C-30 or another plan, it simply
must have real and substantial targets if we hope to make any headway on global
warming.
Global warming is a serious problem, and avoiding scientists’ dire predictions
means actually reducing our emissions, not virtually reducing them, not sort
of reducing them, and not reducing their intensity.
Any plan that uses intensity as a target should go back to the drawing board
until we have something that will actually work.
