How do you calculate greenhouse gas emissions?
GHG emission = 0.001 * Fuel Usage * High heat value *Emission factor. You can get these values from the EPA’s GHG Reporting Program (GHGRP) documentation and your own records.
How much greenhouse gas does the average household emit?
The average US household produces 7.5 tons of CO2 equivalents per year.
What is my family’s carbon footprint?
Your household’s carbon footprint would be the total carbon dioxide released by your home and all the people who live there. A carbon footprint calculator typically takes into account the greenhouse gases you produce at home and while traveling.
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, \%.
What are household emissions?
Many of our daily activities cause emissions of greenhouse gases. For example, we produce greenhouse gas emissions from burning gasoline when we drive, burning oil or gas for home heating, or using electricity generated from coal, natural gas, and oil.
What are greenhouse gases?
The main gases responsible for the greenhouse effect include carbon dioxide, methane, nitrous oxide, and water vapor (which all occur naturally), and fluorinated gases (which are synthetic). Greenhouse gases have different chemical properties and are removed from the atmosphere, over time, by different processes.
What are emissions measured in?
GHG emissions are often measured in carbon dioxide (CO2) equivalent. To convert emissions of a gas into CO2 equivalent, its emissions are multiplied by the gas’s Global Warming Potential (GWP).
How are CO2 emissions measured?
The standard unit for measuring carbon footprints is the Carbon dioxide equivalent (CO2e), which is expressed as parts per million by volume, ppmv. The idea is to express the impact of each different greenhouse gas in terms of the amount of CO2 that would create the same amount of warming.
