ICYMI: Who are the best of the B-Corps?

ICYMI (In Case You Missed It) is a regular GreenBiz feature, recapping the highlights of corporate sustainability news every Monday.

Welcome back, readers! This week has left me hanging: One of my favorite parts of this column is digging into the Odds 'n' Sods section -- those unexpected, unlikely or unbelievable initiatives and announcements that just don't fit in with the rest of the week's news. However, there was such a surplus of other announcements -- it's sustainability reporting season, people! -- and such a lack of odds or sods that I decided to forgo the section entirely this week. Look below for some cool news about B-Corps, fungi-based packaging and VERGE.

And, just to tide you over til next week, do feel free to check out the odds-and-sods of the just-unveiled Pet Industry Sustainability Coalition.

Notable achievements and commitments

Putting carbon-reduction tools in the hands of the people (sort of): Next10 this week release an online tool to help Californians (or anyone, really) explore the ways that the Golden State could reduce its emissions. The California Carbon Challenge walks individuals through a wide range of policy solutions, covering everything from feebates for automobile purchases to smart urban growth to a carbon tax. Each option comes with pros and cons, as well as the carbon reductions possible. It's an interesting way to take in the broad spectrum of carbon solutions on offer.

• The best of the B-Corps: B-Lab, the group behind the B-Corp certification for beneficial businesses, this week released the list of 63 companies from around the world that are "Best for the Environment." Among the biggest names in the honoree list are Method Products, New Leaf Paper, Patagonia and Seventh Generation. Included in the international ranks of "best of" B-Corps are Mas Ambiente, an Argentinian company producing handmade soap from used cooking and frying oil; Vidrios Marte, Mexico's largest insulated-glass manufacturer; and CO2 Bambu, a Nicaragua green building materials firm.

• BT to help dial down customers' emissions: On the heels of its announcement that BT achieved its emissions-reduction goal three years early, the telecom giant has committed to reducing emissions from its customers by three times as much as the reductions from its own operations. The new goal comes after the company determined that just 8 percent of its carbon footprint comes from its own operations, with as much as 28 percent emitted by its customers.

British food retailers tackle food waste: The Co-Operative Group this week announced that it will eliminate food waste sent to landfills by July, five months ahead of schedule.
