OECD’s bad news on carbon tax is hopelessly optimistic

Layers of bad news: OECD says carbon pricing is far too low to fight global warming – an 80% shortfall! But peel back the layers and the story is much worse. The cost of carbon they use for that calculation is seriously low-balled, so the real shortfall should be much higher. And then, deep in the OECD report, we learn that the benefits of motor fuel tax are double-counted – it seems we already needed that money to pay for costs of traffic congestion, local air pollution, and people run over by cars, so there’s little, if anything, left for carbon pollution. Then, following up the OECD’s sources for that double-counting calculation we see that this, too, is understated – it completely ignores the multiplier effects of driving & damage from chasing pedestrians and cyclists off the road. And, finally, if we pay for all that environmental damage with fuel tax, who pays for the roads themselves?

The carbon pricing report is undoubtedly put together by people with a great concern about global warming and effective climate policy, and they’re delivering some bad news. Yet it is hard not to see it as an example of what Kevin Anderson (@kevinclimate) has described: that most of the policy and advocacy and even the science of climate change is presented in colossally over-optimistic scenarios. Let’s peel back the layers to see how that works. Continue reading
