Emissions & Generation Resource Integrated Database mix, and heat input. eGRID data also include plant identification, location, and structural information. The emissions information in eGRID include carbon dioxide (CO), nitrogen oxides (NO), sulfur dioxide (SO), methane (CH), nitrous oxide (NO),and carbon dioxide equivalent (COe). CO, CH, and NO are greenhouse gases (GHG) that contribute to global warming or climate change. NO and SO contribute to unhealthy air quality and acid rain in many parts of the country. eGRID's resource mix information includes the following fossil fuel resources: coal, oil, gas, other fossil; nuclear resources; and the following renewable resources: hydroelectric (water), biomass (including biogas, landfill gas
Low-carbon diet and rail releases carbon dioxide (CO2), the primary gas responsible for global warming. Chlorofluorocarbons (CFCs) are emitted from mechanical refrigerating and freezing mechanisms – both staples in food shipment and storage. Anthropogenic methane emission sources include agriculture (ruminants, manure management, wetland rice production), various other industries and landfills. Anthropogenic nitrous oxide sources include fertilizer, manure, crop residues and nitrogen-fixing crops production. Methane and nitrous oxide are also emitted in large amounts from natural sources. The 100-year global warming potentials of methane and nitrous oxide are recently estimated at 25 and 298 carbon dioxide equivalents, respectively. Steinfeld et al. estimate that
