GHG calculator for solid waste


Greenhouse gas (GHG) emissions from waste management activities and their contribution to climate change is one of the critical environmental concerns. Methane (CH4) is the major GHG emitted from the waste sector, and open dumping and landfilling has been reported as the third highest anthropogenic CH4 emission source. Climate pollutant including black carbon emission from open burning of waste which is practiced in many cities in developing countries is a critical concern. In addition, GHG emissions (e.g. CO2, N2O) from waste handling, transportation and operation of machinery are also significant especially due to the utilisation of fossil-based energy. Unfortunately, local authorities responsible for waste management do not clearly understand the linkage between waste management and climate change.


In 2011, IGES-Sustainable Consumption and Production (SCP) Group, in collaboration with local counterparts, conducted capacity building workshops for local governments to promote waste utilisation for climate change mitigation in Cambodia, Lao PDR and Thailand. Also, there was training on estimations of GHG emissions from waste management practices. However, it was difficult for personnel in local authorities since they are not familiar with the complex equations that are used for GHG estimation. Therefore, IGES developed a simple spreadsheet simulation to facilitate the decision-making of local governments on selection of appropriate technology and designing suitable waste management systems for climate change mitigation, as well as to evaluate their achievement/progress on GHG mitigation.
