Info

Estimated global methane generation – 688 Tg/year (2010). Wastewater contribution is about 8-10% of global estimates. Year 1994 was agreed as the base year for estimations. Total estimated methane emissions from wastewater is expected to increase upto 20 % by next decade since very little efforts are made in this sector for mitigation (please remember methane has GWP of 21).
