Check out Climate Counts, an organization that tracks the steps big business is taking to recognize and deal with climate change. It rates each company out of a hundred according to several criteria. The results may surprise you as they did me!
I was surprised to see that Amazon got a measly 5, as did E Bay. I shop from each of these companies regularly, reasoning that online shopping reduces greenhouse gas emissions, as opposed to driving to and from stores. I also like to try to buy everything second hand if I can, especially books which are a major weakness of mine. This has really made me think twice. I will be going to Bookmans, and Changing Hands even more regularly now, (although both are not so close to me), and supporting my local Goodwill all the more.
McDonald's scored OK-ish with a 27, second only to Starbucks in the food services section! The other fast food places such as Burger King, and the company owning Red Lobster, and Olive Garden did not fare so well with 0 points! Many of the electronics companies such as IBM, and Canon do well also with scores of 77, and 74 respectively, while the top scorer in foods was Stoneyfield Farms with a 78. Nike came in tops overall with a score of 82!
