The average carbon dioxide coefficient of distillate fuel oil is 429.61 kg CO2 per 42-gallon barrel (EPA 2018). Moderator . Carbon Stock Density in Year 2017 = (57,546 MMT C × 106) / (273,623 thou. How much of energy from therms to gigajoules, thm to GJ? 12,146 kWh per home × 998.4 lbs CO2 per megawatt-hour generated × 1/(1-0.069) MWh delivered/MWh generated × 1 MWh/1,000 kWh × 1 metric ton/2,204.6 lb = 5.906 metric tons CO2/home. Btu (I.T.) Learn more AND save money when buying natural gas and electricity. ∆LOrganic = Annual change in emissions from drained organic soils per hectare, EFcropland= 13.17 metric tons C/hectare/year (average of emission factors for drained organic cropland soils in sub-tropical, cold temperate, and warm temperate climates in the United States) (EPA 2019), EFforestland= 2.60 + 0.31 = 2.91 metric tons C/hectare/year (emission factors for temperate drained organic forest soils) (IPCC 2014), ∆Lorganic = 13.17 - 2.91 = 10.26 metric tons C/hectare/year emitted. For reference, to obtain the number of grams of CO2 emitted per gallon of gasoline combusted, the heat content of the fuel per gallon can be multiplied by the kg CO2 per heat content of the fuel. A megawatt hour is equivalent to a power of 1,000,000 Watts being applied for an hour . The fraction oxidized to CO2 is assumed to be 100 percent (IPCC 2006). Intergovernmental Panel on Climate Change, Geneva, Switzerland, Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2017. This method will yield the same result. Urban tree database and allometric equations. Voluntary Reporting of Greenhouse Gases, U.S. Department of Energy, Energy Information Administration. U.S. Environmental Protection Agency. In 2017, the ratio of carbon dioxide emissions to total greenhouse gas emissions (including carbon dioxide, methane, and nitrous oxide, all expressed as carbon dioxide equivalents) for passenger vehicles was 0.989 (EPA 2019). One therm is equal to 1.055 056 × 108 joules. You can view more details on each measurement unit: If you need to convert million BTU to another compatible unit, please pick the one you need on the page below. TOGGLE :   from therms US into one-million British Thermal Units in the other way around. Volume 2 (Energy). Note: When using this equivalency, please keep in mind that it represents the CO2 equivalency of CO2 released for natural gas burned as a fuel, not natural gas released to the atmosphere. If you need to convert million BTU to another compatible unit, please pick the one you need on the page below. Therm is a non-SI unit of heat energy. Headquarters 1230 Higuera St. San Luis Obispo, CA 93401 805 547 2050 Consequently, the change in carbon density from converting forestland to cropland would be -85.27 metric tons of C/hectare/year of biomass plus -4.10 metric tons C/hectare/year of soil C, minus 10.26 metric tons C/hectare/year from drained organic soils, equaling a total loss of 99.62 metric tons C/hectare/year (or -40.32 metric tons C/acre/year) in the year of conversion. (Therm(US) to Btu (I.T.)) 86 p. Method for Calculating Carbon Sequestration by Trees in Urban and Suburban Settings. The IPCC (2006) guidelines indicate that there are insufficient data to provide a default approach or parameters to estimate carbon stock change from dead organic matter pools or belowground carbon stocks in perennial cropland (IPCC 2006). In this example, multiply 400 by 0.0103412 to get 4.14 therms. This page features online conversion from million BTU to normal cubic meter of natural gas.These units belong to different measurement systems. For propane therms to gallons, there are 1.1 (propane) therms per gallon. A kilowatt hour is equivalent to a power of 1,000 Watts being applied for an hour . MCF is the unit of measurement in the oil and gas industry which is used for the measurement of natural gas. Do a quick conversion: 1 therm [U.S.] = 99976.124487811 Btus using the online calculator for metric conversions. Please also note that this calculation method assumes that all of the forest biomass is oxidized during clearing (i.e., none of the burned biomass remains as charcoal or ash).
