GreenBiz Group’s mission is to define and accelerate the business of sustainability. The company, launched in 2005 as Greener World Media, was created to commercialize, the nonprofit website Joel founded in 1999. Since then, along with two business partners, Pete May and Eric Faurot, GreenBiz Group has expanded beyond online media to include research, events, and a membership-based peer-to-peer learning network for corporate sustainability executives from some of the world’s largest companies.

As the company’s chairman and executive editor, Joel guides its editorial vision and serves as the host for its annual events: GreenBiz Forums, centered around the annual publication of GreenBiz’s State of Green Business report, of which Joel is the lead author; and VERGE, a global series of events focusing on the convergence of energy, information, building, and transportation technologies, and the opportunities it brings to business and sustainability.
