What is the priority list?

One of the challenges we have in reducing carbon emissions is that (as far as I know) there's no priority list. Which is worse: leaving your computer on all night or not having the windows weatherstripped? Which is worse: driving a car to Boston or going by plane with 200 other people? Is it worth driving across town to buy a pint of organic strawberries or should I get the ones from the nearby store that came from California? If you have a thousand dollars to invest in making a reduction in greenhouse gasses, should you buy new tires, switch to local foods or perhaps send $900 to help a factory in China switch away from coal and then use the other hundred to have a massage?
Without a list, you can see how making intelligent decisions is impossible, so we resort to confusing activity with productivity.
Back to your office: do you have a list? Have you figured out which metric you're trying to improve? Can you measure the impact of the choices you make all day?
