Council for Responsible Sport is helping athletic events like marathons and triathlons become greener. Many people travel from all over the world to participate in these events and their travels take a serious toll on the environment. Consider this data from the CRS website:
Ironman Hawaii hosted 1,787 athletes on Oct. 13, 2007. Of the starters, only 68 were from the state of Hawaii. Competitors traveled 18,312,992 miles round-trip to reach Kailua-Kona, and nearly all of them traveled by plane. Long airline flights generate an average of 1.3068 lbs of CO2 equivalent per passenger mile.
Thus, athletes on the starting line of Ironman Hawaii produced 23,931,418 lbs (10,853 metric tonnes) of greenhouse gases getting to and from the race. This is equivalent to the yearly carbon footprint (electricity and natural gas) of 972 average American homes.
It would have cost $108,530.00 to offset this carbon by funding carbon-reducing projects managed by EcoSecurities.
