Why spending on a Green New Deal will reduce the public debt, cut carbon emissions, increase energy security and reduce fuel poverty

«Negative emissions «simply work like a «carbon debt» mechanism, but it's somewhat dubious to count on «payback» starting in 2050.

Burning wood instead of coal therefore creates a carbon debt — an immediate increase in atmospheric CO2 compared to fossil energy — that can be repaid over time only as — and if — NPP [net primary production] rises above the flux of carbon from biomass and soils to the atmosphere on the harvested lands.»

The qualitative result that growth in bioenergy raises atmospheric CO2 does not depend on the parameters: as long as bioenergy generates an initial carbon debt, increasing harvests mean more is «borrowed» every year than is paid back.

Focusing on the carbon emissions associated with tropical deforestation, it showed that converting rainforests or grasslands to corn, soybean, or palm oil biofuel production led to a carbon emissions increase — a «biofuel carbon debt» — that was at least 37 times greater than the annual reduction in greenhouse gases resulting from the shift from fossil fuels to biofuels.

For forests in the central and eastern US, which supply much of the wood used in UK power plants, the payback time for this carbon debt ranges from 44 to 104 years, depending on forest type — and assuming the land remains forest.

Even if the forests eventually regrow, notes Prof. Sterman, each year the new carbon debt from increased harvest and combustion outweighs the regrowth, just as borrowing more on a credit card each month than one is able to pay back will steadily increase what he or she owes.

Interestingly, beyond this, despite considerable rhetoric about moving beyond debates about carbon - pricing, the report recommends that in order to avoid adding to the Federal debt, it would be necessary to impose new taxes, including increased royalties for oil and gas extraction, a tax on imported oil, a tax on electricity sales, and a «very small carbon price» (presumably from a modest carbon tax or unambitious cap - and - trade system).

At best, there is no carbon budget left, and at worst (depending on the temperature target selected), we have run up substantial carbon debt.

In practical terms, that means that the amount of time it takes to payback the carbon debt of producing biofuel on that land to replace fossil fuels is even greater than we thought; and pretty much makes palm oil biodiesel produced in such conditions worse than petroleum - based diesel.

We are out of carbon budget; EVERY expenditure of fossil fuel from now on increases our carbon debt, and reduces our chances of avoiding the climate Apocalypse.

While there is no easy answer — it depends on the type of land converted and the productivity of the crop — the study did find that in general soy had the shortest carbon debt, though still decades - long, while palm oil grown on peatland had the longest on average.
