Work is easy or difficult to quantify depending on whether or not your company has calculated its carbon footprint as part of its corporate social responsibility work yet. If you need to do the calculation your self there are going to be two big factors for you to calculate your personal part of that footprint. How far do you travel to work? How much space do you occupy? As a very rough guide use the numbers above for your transportation and 10 pounds of CO2 per sq foot of office space that you occupy. Don’t forget to divide the common space by the number of employees and add your portion of that to your personal space number.
