Greenhouse gas emissions in the state of Morelos, Mexico: A first approximation for establishing mitigation strategies

Abstract

In this study, the authors report the first greenhouse gas emission inventory of Morelos, a state in central Mexico, in which the emissions of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) have been identified using the Intergovernmental Panel on Climate Change (IPCC) methodology. Greenhouse gas (GHG) emissions were estimated as CO2 equivalents (CO2 eq) for the years 2005, 2007, and 2009, with 2005 being treated as the base year. The percentage contributions from each category to the CO2 eq emissions in the base year were as follows: 38% from energy, 30% from industrial processes, 23% from waste, 5% from agriculture, and 4% from land use/land use change and forestry (LULUCF). As observed in other state inventories in Mexico, road transportation is the main source of CO2 emissions, wastewater handling and solid waste disposal are the main sources of CH4 emissions, and agricultural soils are the source of the most significant N2O emissions. The information reported in this inventory identifies the main emission sources. Based on these results, the government can propose public policies specifically designed for the state of Morelos to establish GHG mitigation strategies in the near future. Implications: In this paper, the emissions of greenhouse gases that are generated in the state of Morelos in central Mexico were calculated. The authors calculated carbon dioxide, methane, and nitrous oxide gases emitted from the categories energy, waste, industrial processes, agriculture, and LULUCF. These emissions correspond to 1.24% of the total issued nationwide. These first results will be the basis for mitigation and adaptation strategies against climate change, as well as for establishing public policies in the study area.
