Wow, I am already proud of my future destination, a carbon tax, no less. One that will start off at $10 per tonne of carbon (2.4c per litre of gasoline, or about 9c a gallon) and rise by a factor of three in a few years…

VICTORIA – Finance Minister Carole Taylor introduced an escalating carbon tax on most fossil fuels Tuesday, one she says recycles revenues back to taxpayers and businesses and is designed to ignite an environmental social movement in British Columbia and across Canada to fight climate change.And she’s handing every British Columbian $100 in June as seed money to get them thinking green.

The Canadian Press: BC introduces carbon tax, but off-sets increased fuel costs with tax cuts

The carbon tax advocacy center sets the required starter tax as 10c a gallon, BTW, so this measure by BC is no joke, it’s a serious effort to rein in CO2 emissions from the province. Carbon taxes are in general regressive as they are flat taxes, so the poor pay the same as the rich, but obviously will suffer more. So, what is the BC government doing to ensure that the poor don’t suffer?

The carbon tax revenue, estimated to hit $1.8 billion over three years, will be returned to taxpayers through personal income tax and business tax cuts, she said.The government will introduce legislation that requires it to table an annual plan that shows how the carbon tax revenue will be returned to taxpayers, Taylor said

Good words. But Taylor needs to realize that in the absence of well designed tax offsets, the people and businesses of BC will be at a temporary competitive disadvantage. It’s tricky to be an early adopter, but I am optimistic that BC will be the better for it.

Wonderful, now the rest of Canada (and the US) needs to follow suit. And, I look forward to blogging about Canada already, exciting!

Thanks of course to the grist for alerting me…

Update: An economist allays my regressivity and harm to business fears…

Well, possibly the biggest climate change science news of the day, sequestration with a twist. Now if we can only get those friendly little carbon dioxide molecules to march down a couple of miles down to the ocean sediments to sequester themselves! But seriously, it will take a lot of pumping.

Permanent carbon dioxide storage in deep-sea sediments — House et al., 10.1073/pnas.0605318103 — Proceedings of the National Academy of Sciences

Stabilizing the concentration of atmospheric CO2 may require storing enormous quantities of captured anthropogenic CO2 in near-permanent geologic reservoirs. Because of the subsurface temperature profile of terrestrial storage sites, CO2 stored in these reservoirs is buoyant. As a result, a portion of the injected CO2 can escape if the reservoir is not appropriately sealed. We show that injecting CO2 into deep-sea sediments <3,000-m water depth and a few hundred meters of sediment provides permanent geologic storage even with large geomechanical perturbations. At the high pressures and low temperatures common in deep-sea sediments, CO2 resides in its liquid phase and can be denser than the overlying pore fluid, causing the injected CO2 to be gravitationally stable. Additionally, CO2 hydrate formation will impede the flow of CO2(l) and serve as a second cap on the system. The evolution of the CO2 plume is described qualitatively from the injection to the formation of CO2 hydrates and finally to the dilution of the CO2(aq) solution by diffusion. If calcareous sediments are chosen, then the dissolution of carbonate host rock by the CO2(aq) solution will slightly increase porosity, which may cause large increases in permeability. Karst formation, however, is unlikely because total dissolution is limited to only a few percent of the rock volume. The total CO2 storage capacity within the 200-mile economic zone of the U.S. coastline is enormous, capable of storing thousands of years of current U.S. CO2 emissions.
