There are three steps involved in measuring emissions or carbon credits according to a DEFRA report.
Activity data can be collected in weights (for example of wood, or food) or volume (of gasoline or diesel consumed).
Electricity is measured in total kilowatt hours (k Wh).
EFs for food and drinks is given by Intergovernmental Panel on Climate Change (IPCC) Guidelines for National Greenhouse Gas Inventories (pg. The six pollutants are not equal in the damage they cause to the environment.
Their intensity of effect is called global warming potential (GWP). one pound) of nitrous oxide harms the environment 298 times more than the same amount (eg. In other words one unit of nitrous oxide is equivalent to 298 units of carbon dioxide explains EPA (Understanding Global Warming Potential). To express all the GHGs in terms of carbon dioxide equivalent (CO2e), multiply the emissions of each pollutant with its global warming potential (GWP).
There are many steps involved to get the total emissions from a family or business.
The first step is to calculate emissions from all six pollutants.
Steps are generally the same from country to country.
The steps to calculate emissions are the same across countries, as shown by Shrink That Footprint.
Carbon credits are a vital component of national and international emissions trading strategies to lessen carbon footprints and global warming.
