2. Oil and Gas Conversion Calculator Convert hundreds of different oilfield units of measurement using the calculator below. (This calculation includes carbon stocks in the aboveground biomass, belowground biomass, dead wood, litter, and soil organic and mineral carbon pools. The sum of the carbon stocks in aboveground, belowground, dead wood, and litter biomass (-87.52 metric tons C/hectare). The national weighted average carbon dioxide marginal emission rate for delivered electricity in 2018 was 1,558.8 lbs CO2 per megawatt-hour, which accounts for losses during transmission and distribution (EPA 2019). Propane is 81.7 percent carbon (EPA 2019).

To help facilitate like-for-like comparisons, the industry standardized natural gas production into "equivalent barrels" of oil. These estimates are based on the following assumptions: The estimates of carbon sequestered by coniferous and deciduous trees were then weighted by the percent share of coniferous versus deciduous trees in cities across the United States.

Carbon stock change in soils is time-dependent, with a default time period for transition between equilibrium soil carbon values of 20 years for soils in cropland systems (IPCC 2006). Barrels of oil consumed Carbon dioxide emissions per barrel of crude oil are determined by multiplying heat content times the carbon coefficient times the fraction oxidized times the ratio of the molecular weight of carbon dioxide to that of carbon (44/12). 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. EPA (2016). Pervasive Computing, pp.19-33. The carbon stock in annual cropland biomass after one year is 5 metric tons C per hectare, and the carbon content of dry aboveground biomass is 45 percent (IPCC 2006). Rep. PSW-GTR-253.

Electricity generation from an average wind turbine was determined by multiplying the average nameplate capacity of a wind turbine in the United States (2.32 MW) by the average U.S. wind capacity factor (0.34) and by the number of hours per year. The average wind capacity factor in the U.S. in 2017 was 34 percent (DOE 2018). Standard reference fuels are statistical units of a defined gross heat content. The nursery-grown trees are then planted in a suburban/urban setting; the trees are not densely planted.

To determine annual greenhouse gas emissions per mile, the following methodology was used: carbon dioxide emissions per gallon of gasoline were divided by the average fuel economy of vehicles to determine carbon dioxide emitted per mile traveled by a typical passenger vehicle. Chapter 2: Drained Inland Organic Soils.

The BOE is used by oil and gas companies in their financial statements as a way of combining oil and natural gas reserves and production into a single measure, although this energy equivalence does not take into account the lower financial value of energy in the form of gas.

In 2018, there were 120.3 million homes in the United States (EIA 2019a). Hancock (2001). Standard reference fuels are statistical units of a defined gross heat content ; Natural gas equivalents assume 1000 Btu/ft 3 gross - or 9400 kcal/Nm 3 or 39.4 MJ/Nm 3 ; Sponsored Links . 86 p. Method for Calculating Carbon Sequestration by Trees in Urban and Suburban Settings. Environmental Protection Agency, Washington, D.C. EPA #430-R-19-001 (PDF).

Therefore, AVERT provides a national marginal emission factor for the Equivalencies Calculator. 2013 Supplement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories: Wetlands. You can target the Engineering ToolBox by using AdWords Managed Placements.

Please read AddThis Privacy for more information. Averaged across households in the United States, this amounts to 40,190 cubic feet of natural gas, 45 gallons of liquefied petroleum gas, and 29 gallons of fuel oil per home. McPherson, E. G.; van D. N. S.; Peper, P. J. To start using the calculator now, British Thermal Units per Pound - Degree Farenheit, British Thermal Units per Hour -Feet -Degree Farenheit, Million Standard Cubic Feet per Day per Pounds per Square Inch, Standard Cubic Feet per Day per Pounds per Square Inch, Cubic Feet per Day-Pounds per Square Inch. Understanding Human-Smartphone Concerns: A Study of Battery Life. The fraction oxidized is assumed to be 100 percent (IPCC 2006). 0.1 mmbtu/1 therm × 14.43 kg C/mmbtu × 44 kg CO2/12 kg C × 1 metric ton/1,000 kg = 0.0053 metric tons CO2/therm.

Carbon dioxide emissions reduced per trash bag full of waste were determined by multiplying emissions avoided from recycling instead of landfilling 1 ton of waste by the amount of waste in an average trash bag. These applications will - due to browser restrictions - send data between your browser and our server.

To estimate CO2 not emitted when an acre of forest is preserved from conversion to cropland, simply multiply the number of acres of forest not converted by -147.83 mt CO2/acre/year. Carbon dioxide emissions were then divided by the ratio of carbon dioxide emissions to total vehicle greenhouse gas emissions to account for vehicle methane and nitrous oxide emissions. AddThis use cookies for handling links to social media. 8.89 × 10-3 metric tons CO2/gallon gasoline × 11,484 VMT car/truck average × 1/22.3 miles per gallon car/truck average × 1 CO2, CH4, and N2O/0.989 CO2 = 4.63 metric tons CO2E/vehicle /year.

), Annual Net Change in Carbon Stocks in Year 2017 = 57,687 MMT C – 57,546 MMT C = 141 MMT C. Step 2: Determine the annual net change in carbon stocks (i.e., sequestration) per area by dividing the carbon stock change in U.S. forests from Step 1 by the total area of U.S. forests remaining in forests in year t (i.e., the area of land that did not change land-use categories between the time periods). According to WARM, the net emission reduction from recycling mixed recyclables (e.g., paper, metals, plastics), compared with a baseline in which the materials are landfilled (i.e., accounting for the avoided emissions from landfilling), is 2.94 metric tons CO2 equivalent per short ton, as calculated in the “Tons of waste recycled instead of landfilled” section above.
