Before and after - from boreal forest to strip mining, that's tar sands.

Oil is rubbish. I mean, obviously it's been great - you know, they way that it underpins what we call 'advanced industrial civilisation' - that we can make it into petrol, plastic, pharmaceuticals, fertiliser. That's obviously brilliant, because in my opinion all that stuff has (by and large) been great. But now that we've got better, cleaner and smarter ways to power our cities, run our cars and heat our homes forgive me if I find the black stuff a bit... last century. Read more »

We called for strong climate action from the US. But support for the proposed climate bill is being undermined by BP.

It's not perhaps the most surprising of news, but it is worth noting. BP USA has quit a leading business coalition that's been lobbying for a climate bill to cut carbon emissions in the states.

You can be sure that what goes on in the States will have been approved from the London office, where over the past few years BP have been working hard to create the impression of a company that has moved away from fossil fuels. So does this move mark an admission of oily business-as-usual from the company that claims it is "beyond petroleum"? Read more »

Canada before and after tar sands extraction. Producing tar sands oil is also at least three time more carbon intensive than making normal crude.

Some dirty oil news bubbled up over the weekend, as big oil companies including Shell and BP mobilise to try and stop tar sands oil being banned from the sixth largest economy in the world.

That would be California, personal fiefdom of 'surprisingly green governor' Arnie Schwarznegger. In an effort to cut vehicle emissions 10 per cent by 2020, he has brought in laws that require a cut in the carbon content of fuels sold in the state. "Our cars have been running on dirty fuel for too long," intoned Arnie, in his rich Austrian accent.

The American Petroleum Institute is the kind of friendly industry body that lobbies for 'big oil', and has no trouble inspiring grassroots action. The trouble is, from their point of view, it's the wrong kind.

For the oil companies, it must be incredibly tedious to have masses of engaged citizens fired up about the way you're trashing the planet - camping out on your lawn, organising rallies, chaining themselves to your office, asking pointed questions to politicians. How irritating that there are people who think you're so wrong they'll actually get out onto the streets and protest about it! It sucks to be on the wrong side of history.

It's big energy money week! Get your annual financial thrills as the big international oil companies - Shell, BP, ExxonMobil and the rest - publish their quarterly financial reports results this week, all at once!

And if you like a gory financial thriller, they promise to be quite a good read, because profits are tanking. Take Shell, for example. When your quarterly profits fall by 70% in one year, you know something's gone a bit wrong. ExxonMobil's are down by 66%. BP's profits have more than halved. The global economic downturn is kicking in. Read more »

We know tar sands are destructive, bad for the climate, and expensive to exploit. But could they also be a colossal financial liability for BP and Shell?

If, in the runup to Copenhagen, you have a sneaking suspicion that world leaders might still be more attached to the realpolitik of energy than the green-tinged adoption of strong climate policy, a new report from Greenpeace, Platform and Oil Change International may provide a glimmer of hope.

The suspicion is that whatever grand statements are made by the Obamas, the Lulas or the Browns of the world as they thrash out their meta-climate policy at Copenhagen, for the moment they're going to remain much more motivated by ‘energy security' than greenhouse gas stabilization.

Getting to be 100 years old is a proud milestone, but it usually comes with some complications - which can include a loss of critical faculties. As BP directors and shareholders meet to celebrate the company's centenary in London this evening, they'd be well advised to seriously question whether BP's massive investment in Canadian tar sands (pictured here) is evidence of senility setting in.

Last month our Emerald Paintbrush award presented to BP highlighted how far the company, which previously styled itself as going 'beyond petroleum', has moved back to its traditional profit source at the expense of its alternative energy division, and most likely its long-term profitability.

Investors may have been patting themselves on the back yesterday as BP posted record profits for 2008, but they should be wary - a quick trawl through the figures reveals major flaws in the company's long term investment strategy. Massive profits during the first half of the year (when oil prices reached over $100 per barrel) were undermined by a collapse in the final quarter, when prices fell back to around $40 per barrel.
