Commit to a year without driving a car in relation to your work.
Walk, ride a cycle, catch a bus, take a train, get a taxi, or share a ride in someone else's car. But don't drive a car!
Watch your professional carbon footprint, business and social costs shrink like dead balloons. Experience your health and fitness growing dramatically. Learn deeper business management and growth skills. Make a difference in and through your business.
Most importantly, share your experiences, learnings and successes with others!
You can find my final 'reporting' blog on the project here http://www.supplejack.co.nz/i/25/74/Blog/Not-driving%3A-business
My car-free year ran from November 2010 to end of January 2012.
As a result, I managed to reduce my carbon emissions to under a third from 2009 to then end of the 2012 financial year.
I also managed to 'nearly' (within a few $$) remove social costs from my business. A little bit more cycling and walking, and my business would have started generating social benefits.
