As Spheric employees we are required to travel quite a bit due to the nature of our work. But we can still be green while doing it.
Air travel produces approximately 12% of the world’s transport CO2 emissions, although Boeing is working on plane engines that could be burning bio-fuel (Treehugger.com), it won’t be ready for 3-5 years. To reduce our footprint we try to work remotely but it’s not always possible. When we need to fly, we chose to offset our CO2 emissions with the airline ( like AirCanada’s Carbon Offset Program or Continental’s Eco-Skies Program). For those flights that we couldn’t offset through the airline, we purchase Offset credits every quarter.
