SAN FRANCISCO, CA — Sustainability cannot be a small add-on that is tacked to the end of company's business plan, but needs to be infused throughout the whole of a company, said Nancy Fell, sustainability chair of the startup-funding Cleantech Open at a State of Green Business Forum workshop.

Speaking at the "Jumpstarting Your Triple Bottom Line Green Enterprise" session, Fell said there are four key criteria to add sustainability to a business plan, along with the typical issues like funding, marketing and operations, in order to make it a fully sustainability-focused business plan.
