About us

Green Street USA’s curated product lists reflect the collective wisdom of a team of accomplished sustainability advisors and small business owners. They rest on a foundation of 3 core principles.

Our Principles

View “sustainability” through your eyes 

The size of your environmental footprint is measured by the appliances you buy, the materials you use, and the products you sell. Our curated, Main Street-focused lists of goods and services advance the sustainability of your operations and improvements without breaking the bank.



Main Street enterprises can embrace the growing sustainability imperative one step at a time by deploying more energy-efficient business practices; expanding usage of renewable electricity; reducing waste; conserving water where possible; supporting the health, vitality and wellbeing of employees and communities; and strengthening business resilience.

Provide trusted solutions

Our vetted recommendations feature: improvements that are EPA Energy Star rated, WaterSense labeled or otherwise environmentally preferable; professional services that improve the sustainability of your business activities; and hand-picked advisors who help you dive deeper or go “beyond green.”

Joel is a writer, editor and entrepreneur who has started five companies, selling three and shuttering one, which is not a bad track record when you consider how rough it is out there. Along the way, he co-produced a feature film and wrote 11 books and half a dozen screenplays, one of which will soon be turned into a short film. A certified LEED Green Associate, he is currently pursuing a masters in environmental studies from the University of Pennsylvania with a concentration in sustainability.

Not satisfied with those accomplishments, he is a Visiting Scholar at the Environmental Law Institute and frequent writer and speaker on the topic of corporate sustainability. When Joel challenged Alan to take his expertise from the corporate world to help smaller businesses embrace sustainability, he jumped at the chance.
