There are some people who are in charge of looking at IMC's environmental footprint in each office. I think we also donate quite a large sum of money to offset our carbon footprint globally (If I remember correctly, it's around double the amount we should be contributing).
The company has stated its intention to compensate its not insignificant energy consumption through the use of carbon offsets. It participates in some of the "green" events which the office building and environs organise.
More focus on reducing carbon emissions in terms of the datacentres we use and also by offsetting our emissions by purchasing carbon credits
Have initiatives to reduce power consumption. Part of the monthly updates.
