The G7 and its 85year carbon pledge

If you thought it was hard to keep up your New Year's resolution, try keeping an 85-year pledge.

That's exactly what Canada and the other G7 countries are committing themselves to as they try toget control of global greenhouse gases. While Canada failed on its Kyoto agreement and won't meet its 2020 Copenhagentarget, that's not stopping Prime Minister Stephen Harper from making even morelong-lived environmental pledges.

First, a deep cut in carbonemissions by 2050 and second,an eventual end tofossil fuel useby 2100.

At first glance, it's praiseworthy. The world's leading economiescommittodecarbonthe world economy. Someenvironmental groups were quick to call the G7 announcement "groundbreaking," although not everyone is as supportive and approving.

• Stephen Harper agrees to G7 'decarbonization' by 2100
• How G7's long-term decarbonization plan compares to other major goals
• As It Happens:Canada agrees to 'decarbonization' and to phase out fossil fuel use by 2100

"It's not groundbreaking. It is politically cheap to pledge a non-binding commitment that falls way behind someone's time in office,"said David Keith, an engineering professor at Harvard Universityand former University of Calgary professorwho was one of Timemagazine's "heroes of the environment" in 2009.

"What we really need is specifics in the next few years or decades."

Vague on execution

The pledges do add weight to the movement to get off of fossil fuels, but how the G7 countries achieve their goalsis unclear.

The problem with the G7 is the simple fact there are only 7 countries involved. Even if the group dramatically cuts emissions, there will be little impact on climate changeif developing countries do not take similar actions.

The G7 admitted as much, noting it will only be able to reach its 2050 target, "recognizing that this challenge can only be met by a global response."

Carbon tax

There are many ways Canada could act to try tocontrol greenhouse gases. First and foremost is a carbon tax or carbon pricing similar to what is already in place in British Columbia. Even some members of Alberta's oil industry arein favour of such a system.

Keith argues it's the most effective step to take.

"We need to put in an economic disincentive against using the atmosphere as a free wasteland," he said.

While Canada has failed to follow environmental promises in the past, it's debatable whether the latest pledges will be kept.

At the G7 meeting,Canada and Japanblocked attempts at a stronger statement on binding greenhouse gasreduction targets, according to sources quoted byThe Canadian Press.

"That's shameful," said Keith. "If you want a stable climate, we have to get to net zero emissions. For a government to try and avoid such a statement, is really a shame."

Nuclear

Several environmental groups praised the G7 countries for declaring war on carbon, which, they say,will surely lead to arise in renewable energy. But the G7 never actually said that renewables will be the energy source of the future. They only mentioned the need for carbon-free energy. In effect, the group of countries left the door open to nuclear energy.

Nuclear power has been praised as aclimate change fighter because of its reliability andnear-zero emissions. Nuclear power alreadyprovides 11 per cent of the world's electricity, according to the World Nuclear Association.

Oilsands

The G7 emission targets seem to be a death sentence for Alberta's oilsands. It's no secret the oilsands are a high cost and high carbon operation. Not only is the sector battling low commodity prices right now, any type of carbon reduction strategies, such as a carbon tax, would add extra financial pressure. The industry will have to find a way to remain competitive if the global economy shifts its focus towards low carbon.

"We are all clear,we are still going to need fossil fuels for some time to come. Now we have, at the global level, the latest day for when we need to be off fossil fuels," said Ed Whittingham, with the PembinaInstitute, an environmental thinktank. "CEOs in Calgary are smart;they will do the planning that needs to be done."

If you like promises about the environment, there are more to come. Countries will be lining up to announce even morepledges later this year at the United Nationsclimate change conference in Paris in December.
