I thought this was sort of cool
A common observation by bicycling environmentalists is that large cycling races produce tremendous quantities of greenhouse gases.
The Tour of California, for example, will generate an estimated 518 tons of carbon dioxide from support vehicles, media vans, and cars and trucks driven by spectators and fans.
To offset this, Clif Bar announced they will purchase enough renewable energy credits to offset the CO2 produced during the Amgen Tour of California as part of their sponsorship of the eight day race.
According to Clif Bar, the Tour of California will be the first-ever climate-neutral professional cycling race.
