Emissions and Waste

Emissions and Waste Sector

Purpose and Perspective

The Emissions and Waste sector calculates fossil fuel emissions for CO2, N2O, SOx and CH4, as well as fossil fuel greenhouse gas emissions in CO2 equivalent. The calculation of emissions is based on fossil fuel consumption and physical conversion factors. It also calculates non-energy emissions from agriculture activities (based on the level of activity), from the production of cement (based on population size and income level), and from land use changes (based on deforestation and reforestation). In addition, this sector calculates the generation and management of solid waste. We consider waste generation at both the urban and rural level, and costs of collection and disposal.

Model Structure and Major Assumptions

  • PM2.5 emission parameters for fossil fuels and vehicles are based on Klimont et al (2002) [1]

  • PM2.5 emission parameters for biomass are based on Nussbaumer et al. 2008 [2]

  • CO2, N2O and CH4 are the major contributors to total emission of greenhouse gases [3]

  • Waste collection and disposable unit cost are estimated based on World Bank (2012) [4]

  • Emissions from land use change are based on IPCC (2000) [5]

Exogenous Input Variables


Initialization Variables

  • Initial per capita waste generation - Units: Kg/(Person*Day)

Modeling Details

In order to calculate future emissions in CO2 equivalent we use constant conversion factors. In reality, such factors can change based on the properties of the fuels being used. Should such information about future fuels quality be available, the model can flexibly accept time-varying conversion parameters.
