How are carbon credits calculated

how are carbon credits calculated


We calculate emissions from electricity generation based off figures from the EPA’s eGRID emission factors based on 2009 and 2012 data. On average, electricity sources emit 1.222lbs CO2  per kWh (0.0005925 metric tons CO2  per kWh). State CO2  emissions per kWh may vary greatly in accordance with the amount of clean energy in the energy supply (Vermont: 0.0055 lbs/kWh; North Dakota: 2.0685 lbs/kWh).

There are 0.005 metric tonnes of CO2  per 1 therm of natural gas. (Source: EPA Clean Energy )

US avg. In 2010, 65.5 million households used natural gas. Collectively, they used 4,787 billion cubic feet of natural gas annually, or 730.84 CCF (approximately 748.38 therms) per household or 283.27 CCF (approximately 290.07 therms) per person per household using natural gas.

CO 2 emissions in

air travel vary by length of flight, ranging from 0. 277 kg CO 2 per passenger mile to 0.185 kg CO 2 per passenger mile, depending on the flight distance. Our calculator allows the user to take the issue of radiative forcing into account. (Sources: EPA Climate Leaders . table 4, page 7 ; For more information on air travel-related radiative forcing, please see this IPCC document.) *Assumes Coach Class, please contact us directly for business and first class emissions.

On average, bus trips emit 0.107kgs CO 2 per passenger mile (Source: EPA Climate Leaders table 3, page 5). Road and transportation conditions vary in real life beyond what can be estimated. To ensure that our bus calculator fully covers your trip, we add 10% to the total mileage of your trip to account for potential traffic jams, detours, and pit-stops that may arise on your trip.
