Why? There's a simple answer: Canada is developing the world's second largest reserve of oil. Did I say oil? It's actually a filthy mixture of bitumen, sand, heavy metals and toxic organic chemicals. The tar sands, most of which occur in Alberta, are being extracted by the biggest opencast mining operation on earth. An area the size of England, comprising pristine forests and marshes, will be be dug up – unless the Canadians can stop this madness. Already it looks like a scene from the end of the world: the strip-miners are creating a churned black hell on an unimaginable scale.
To extract oil from this mess, it needs to be heated and washed. Three barrels of water are used to process one barrel of oil. The contaminated water is held in vast
tailings ponds, some so toxic that the tar companies employ people to scoop dead birds off the surface. Most are unlined. They leak organic poisons, arsenic and mercury into the rivers. The First Nations people living downstream have developed a range of exotic cancers and auto-immune diseases.
Refining tar sands requires two to three times as much energy as refining crude oil. The companies exploiting them burn enough natural gas to heat six million homes. Alberta's tar sands operation is the world's biggest single industrial source of carbon emissions. By 2020, if the current growth continues, it will produce more greenhouse gases than Ireland or Denmark. Already, thanks in part to the tar mining, Canadians have almost the highest per capita emissions on earth, and the stripping of Alberta has scarcely begun.
Canada hasn't acted alone. The biggest leaseholder in the
tar sands is Shell, a company that has spent millions persuading the public that it respects the environment. The other great greenwasher, BP, initially decided to stay out of tar. Now it has
invested in plants built to process it. The British bank RBS, 70% of which belongs to you and me (the government's share will soon rise to 84%), has
lent or underwritten £8bn for mining the tar sands.
The purpose of Canada's assault on the international talks is to protect this industry. This is not a poor nation. It does not depend for its economic survival on exploiting this resource. But the tar barons of Alberta have been able to hold the whole country to ransom. They have captured Canada's politics and are turning this lovely country into a cruel and thuggish place.
Canada is a cultured, peaceful nation, which every so often allows a band of Neanderthals to trample over it. Timber firms were licensed to log the old-growth forest in Clayaquot Sound; fishing companies were permitted to destroy the Grand Banks: in both cases these get-rich-quick schemes impoverished Canada and its reputation. But this is much worse, as it affects the whole world. The government's scheming at the climate talks is doing for its national image what whaling has done for Japan.
I will not pretend that this country is the only obstacle to an agreement at Copenhagen. But it is the major one. It feels odd to be writing this. The immediate threat to the global effort to sustain a peaceful and stable world comes not from Saudi Arabia or Iran or China. It comes from Canada. How could that be true?
