I mostly look at things that CWLP ought to do, or things that you can do in your home, and on occasion about changing larger patterns of how we live. But climate change is a comprehensive problem, so we can't let anything slip by. Electricity generation, transportation, home energy use, food miles--these are the biggies that we mostly talk about when we talk about fighting climate change. The big unknown is the embodied energy (and greenhouse gas emissions) in what we buy.
So it's good news that we now have Climate Counts, an effort to rate the brands we buy for their climate friendliness. Joel Makower has a good backgrounder and explanation. The short version is that Climate Counts looks at what companies do to monitor and reduce their emissions, as well as what public policies they support and how open they are with all of that information.
I don't imagine that this is hugely crucial information--I suspect that the people who are most likely to take big actions based on these rankings are already moving into lifestyles where they aren't as important, and everyone else is going to decide their purchases based on other qualities. But, if you're ambivalent between McDonalds, Wendys, and Burger King, but still wedded to the fast food hamburger, maybe this can nudge you over to climate-friendly option.
