Outline of GHG Mitigation Activity

This project is power generation by gas engine using collected methane gas from landfill at three landfill sites in Mexico.

The methane gas recovery system consists of recovery wells, pipelines, gas filters, gas engine generator and transformer. Captured methane gas is transported to the gas engine power generation facilities through pipelines and filters.

Electricity generated from the gas engine generator will be sold under long-term PPAs with local municipality.

GHG emission reductions are achieved by replacement of grid electricity and avoidance of methane emission from landfill sites.

Expected GHG Emission Reductions

244,629 [tCO2/year]

= Emission reductions by electricity generation

   + Emission reductions by methane recovery

Emission reductions by electricity generation

=17,180[tCO2/year] ≒ electricity generation 37,843 [MWh/year]

 × grid emission factor 0.454 [tCO2/MWh]

Emission reductions by methane recovery

= 227,449 [tCO2e/year]
