  • Extensive measurements of the emissions of methane, nitrous oxide and ammonia from wastewater treatment facilities in the USA present higher values than are currently stated in national inventories. The results of this analysis show that greenhouse gas and nitrogenous emissions from the wastewater sector are often overlooked and that their impact on climate should be reassessed.

  • At present, methods to estimate nitrous oxide (N2O) emissions from wastewater treatment have intrinsic limitations leading to large uncertainties and inaccuracies. Here the authors introduce a tier-based approach to enable more-precise estimation of wastewater N2O emissions.

  • The methane emissions from natural gas vehicles (NGVs) are unclear. Here the authors report high methane emissions from heavy-duty NGVs, and by using a scenario analysis show that strictly implementing the upcoming China VI standard could reduce GHG emissions by 509 Mt CO2eq for 2020-2030.
