National Emissions Inventory

The Environmental Management Bureau (EMB) is required under RA 8749 to conduct an inventory of emissions once every three years. Emissions inventory estimates emissions coming from stationary, mobile and area sources.

The rest (11%) were from area sources such as construction activities, open burning of solid wastes, kainginin the upland, among others.
