Sentences with phrase «initial carbon debt»

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.

«Growth in wood supply causes steady growth in atmospheric CO2 because more CO2 is added to the atmosphere every year in initial carbon debt than is paid back by regrowth, worsening global warming and climate change.

More precisely, atmospheric CO2 rises as long as NPP [net primary production] remains below the initial carbon debt incurred each year plus the fluxes of carbon from biomass and soils to the atmosphere.»

Not exact matches

These forests grow back slowly, so it takes a long time to repay the initial «carbon debt» incurred by burning wood instead of coal.
