Emissions
No T1 or T2 event at this site.
No T1 event, so no annual estimate.
Screening-grade satellite estimate: confirm with a hyperspectral satellite, an OGI drone or a ground survey before enforcement or carbon crediting.
Detection and limits
Steady emission above 10 t/h is ruled out (95%).
Over dense Indian landfills a single pass catches about 25–35% of plumes of 10 t/h or more.
