Environmental Economics

Mark Thoma: Brad Plumer hints at a change in the politics of a carbon tax: If we need taxes, why not pollution taxes?, So why not do that through a tax on carbon pollution or other assorted environmental unpleasantries? After all, if we have to raise revenue, we may as well slap higher taxes on behavior we'd like to discourage (like pollution and congestion) rather than, say, labor, no? C]ompared with the rest of the world, we vastly undertax pollution.

Shocking analysis by country of years left to zero emissions

Green Blog

We all know that we have to reduce greenhouse gas (GHG) pollution and eventually reach zero emissions. Indeed top climate scientists and biologists are telling us that reaching zero emissions is not enough – we then have to reduce atmospheric carbon dioxide (CO2) concentration from the current 394 parts per million (ppm) to 350 ppm (according to 350.org ) and thence to 300 ppm ( according to the latest science-informed 300.org ).

Analysis by country of fossil fuel burning-based Carbon Debt and Carbon Credit

Green Blog

Fossil fuel burning yielding the greenhouse gas (GHG) carbon dioxide (CO2) is a major component of man-made global warming. In relation to carbon pollution from the burning of fossil fuels, Net Carbon Debt is equal to the Historical Carbon Debt (from fossil fuel burning since the start of the Industrial Revolution in circa 1750) minus the Carbon Credit (the residual carbon pollution from fossil fuel burning permitted between now and zero emissions in 2050).
