Modifications (procedures) made to the IPCC guidelines summary and their application to 2010 scenario
| Scenario . | Methane correction factor, MCFj . | Pathways description . | Population data . |
|---|---|---|---|
| Procedure 1: Baseline 2010 scenario | |||
| 2010 | All those fromTable 4 | T11 = Rural population with non-controlled wastewater discharge; T12 = Rural population with septic tanks; T13 = Rural population with wastewater treated at WWTPs; T21 = Urban population with non-controlled wastewater discharges; T22 = Urban population with septic tanks; T23 = Urban population with treated wastewater at WWTP | U1 = Rural population; U2 = Urban population as considered in the 2010 Census |
| Procedure 2: Income level approach | |||
| 2010 | All those fromTable 4 but for septic tanks, for which a MCF of 0.1 was used for small families (3–5 persons) and 0.5 (as proposed in the table) for bigger families as recommended by the IPCC guidelines | T11 = Low income rural population with non-controlled wastewater discharges; T12 = Low income rural population with septic tanks; T13 = Low income rural population with wastewater treated at WWTPs; T21 = High income rural population with non-controlled wastewater discharges; T22 = High income rural population with septic tanks; T23 = High income rural population with wastewater treated at WWTPs; T31 = Low income urban population with non-controlled wastewater discharges; T32 = Low income urban population with septic tanks; T33 = Low income urban population with wastewater treated at WWTPs; T41 = High income urban population with non-controlled wastewater discharges; T42 = High income urban population with septic tanks; T43 = High income urban population with wastewater treated at WWTPs | U1 = Low income rural population; U2 = High income rural population; U3 = Low income urban population; U4 = High income urban population. Data from the metadata base Population and Housing Census 2010 (INEGI 2016) |
| Procedure 3: Methane correction | |||
| 2010 | All those fromTable 4 , but 0.22 MCF factor for releases from septic tanks (Leverenz et al. 2010) | T11 = Rural population with non-controlled wastewater discharge; T12 = Rural population with septic tanks; T13 = Rural population with wastewater treated at WWTPs; T21 = Urban population with non-controlled wastewater discharges; T22 = Urban population with septic tanks; T23 = Urban population with treated wastewater at WWTP | U1 = Rural population; U2 = urban population as considered in the 2010 Census |
