It’s been a few months since I went to a Somerville Commission on Energy and Climate Change meeting. That’s more because of being busy than anything else. Today, I went to the March meeting of the Somerville Commission on Energy and Climate Change. A big focus of the agenda was zoning, with the planning department giving a presentation. And another focus was on shadow carbon pricing — it was very interesting to hear about the capital pricing model they developed, incorporating carbon pricing, to see how it would affect capital projects and municipal procurement. The disappointing answer is not much. It’s better to change a purchase spec to accommodate sustainability in the first place.
