The US Southern Alliance for Clean Energy (SACE) has calculated that it has reduced its CO2 emissions from 2010 to 2011 by around 20 metric tons, equivalent to 4 cars being taken off the road.
It calculated carbon emissions associated with its biodiesel manufacturing, office energy consumption, air and ground transportation and overnight stays related to work.
In 2009 and 2010 it contracted the agency Verus Carbon Neutral to calculate its emissions, but this year it calculated them itself.
“The major benefit of calculating our footprint on our own is that we know what all of our assumptions are, and therefore can easily understand exactly what causes our emissions to go up or down each year,” SACE said.
Emissions from air travel were reduced for the third year in a row, but its ground transportation – from rental vehicles and from employee commuting – increased.
In the future it anticipates further drops in emissions, due to office energy efficiency improvements, installing a 9.6kW solar panel, and purchasing a Nissan Leaf (electric) company car. Improvements were also made to data tracking, to record the miles per gallon of every rental vehicle used.
Also in 2012 the company sold its biodiesel operations to Clean Energy Biofuels, and we closed two of its smaller offices in Athens, Georgia and Savannah, Georgia.
