Implications of regional N2O–N emission factors on sugarcane ethanol emissions and granted decarbonization certificates

Reducing greenhouse gas (GHG) emissions by substituting fossil fuels depends on how biofuels are produced and how emissions are calculated. Nitrous oxide (N2O) emissions from synthetic and organic N fertilizers are important sources of GHG from sugarcane ethanol. This study aimed to synthesize the literature information and derive regional N2O emissions factors (EFs) for N fertilizers according to Tier 2 approach. This study also evaluated how...
