What is default emission factor?
The ‘CoM Default Emission Factors’ collection consists of emission factors and coefficients provided to the Covenant of Mayors inititiave for the calculation of local Greenhouse Gas (GHG) emission inventories (in CO2 and CO2 equivalent), using standard (e.g. based on IPCC factors) or LCA (Life cycle assessment) …
What is the emission factor for natural gas?
Carbon Dioxide Emissions Coefficients
| Pounds CO2 | Kilograms CO2 | |
|---|---|---|
| Carbon Dioxide (CO2) Factors: | Per Unit of Volume or Mass | Per Million Btu |
| Natural Gas | 120.96 thousand cubic feet | 52.91 |
| Finished Motor Gasolinea | 17.87 gallon | 67.38 |
| Motor Gasoline | 19.37 gallon | 70.66 |
How do you calculate emission factor?
The general equation for emission estimation is: E = A x EF x (1-ER/100) where: E = emissions, A = activity rate, EF = emission factor, and ER = overall emission reduction efficiency, %.
How is tco2e calculated?
For electricity, the calculation will be 15,000kWh x 0.21233kgCO2e ÷ 1,000 = 3.2tCO2e. For natural gas, the calculation will be 20,000kWh x 0.18316kgCO2e ÷ 1,000 = 3.7tCO2e.
What is the CO2 emission coefficient?
The average carbon dioxide coefficient of natural gas is 0.0551 kg CO2 per cubic foot (EIA 2019). The fraction oxidized to CO2 is 100 percent (IPCC 2006). The average carbon dioxide coefficient of distillate fuel oil is 431.87 kg CO2 per 42-gallon barrel (EPA 2021).
What is tCO2 MWh?
A “grid emission factor” refers to a CO2 emission factor (tCO2/MWh) which will be associated with each unit of electricity provided by an electricity system. It is a parameter to determine the baseline emissions for CDM projects in the renewable energy sector (hydro, wind, solar PV, and geothermal power, etc.)
What are the emissions from a gas boiler?
Combustion of standard fossil fuels (natural gas and ASTM Grade Oil) in commercial and industrial boilers results in the following nine emissions; carbon dioxide, nitrogen, oxygen, water, carbon monoxide, nitrogen oxide, sulfur oxides, volatile organic compounds, and particulate matter.
What is the co2 emission coefficient?
What is Defra emission factors?
The Emissions Factors Toolkit (EFT) is published by Defra and the Devolved Administrations to assist local authorities in carrying out Review and Assessment of local air quality as part of their duties under the Environmental Act 1995.
How do you calculate baseline emissions?
The baseline is calculated by multiplying forecast production by the emissions intensity of that production (tonnes of carbon dioxide equivalent – t CO2-e) per unit of production).
What does kt of CO2 equivalent mean?
kiloton
The unit of measurement is kt (kiloton). Carbon dioxide emissions are often calculated and reported as elemental carbon. The were converted to actual carbon dioxide mass by multiplying them by 3.667 (the ratio of the mass of carbon to that of carbon dioxide).
What causes high NOx in a boiler?
NOx emissions from boilers are influenced by many factors. The most significant factors are flame temperature the amount of nitrogen in the fuel, excess air level and combustion air temperature. Also, a longer residence time at high temperatures results in higher NOx.
How can I reduce my boiler emissions?
Switching coal with the natural gas or biomass is an attractive option for reducing boiler SO2 emissions because these emissions are a function of fuel S content. For example, combustion of natural gas produces far less SO2 emissions than coal does because of the significantly lower S content of natural gas.
What is emissions baseline?
For soil carbon projects, the emissions baseline is the amount of emissions expected or calculated from the alternative scenario before the project starts. The baseline is calculated over the ‘baseline emissions period’, which is usually the five years before the project starts.
What is a GHG baseline?
Baseline emissions refer to the production of greenhouse gases that have occurred in the past and which are being produced prior to the introduction of any strategies to reduce emissions. The baseline measurement is determined over a set period of time, typically one year.
What is MMT CO2?
Metric tons of carbon dioxide equivalent or MTCO2e is the unit of measurement in this tool. The unit “CO2e” represents an amount of a GHG whose atmospheric impact has been standardized to that of one unit mass of carbon dioxide (CO2), based on the global warming potential (GWP) of the gas.
