For Indian waste lands the average annual CO2
sequestration rate in the standing biomass per ha is
estimated to be 2.25 t CO2 ha-1 year-1. Estimates from
ICRISAT – Hyderabad (Sridevi and Wani, 2009) show
carbon sequestration capacity of 74 kg from a ten year old
tree. The amount of CO2 released by Pongamia system
(1.5 t ha-1) can be sequestered by Pongamia trees of
standing biomass of waste land and still can absorb 0.5 to
1 t of CO2, which is very encouraging
