Our Mission: Use the collective power of Bay Area general contractors to catalyze action towards net-zero-impact construction and inspire industry peers to commit to market transformation for a thriving and sustainable future.

What We Do

We use our combined knowledge, resources, experience and relationships to move the Bay Area construction industry away from unsustainable practices and to accelerate market transformation toward positive solutions. We use our role and influence in a relatively traditional industry to ask tough questions, push the status quo, and share unique solutions to drive change.

Our focus areas include the following:

Construction Waste


Material Transparency

Jobsite Practices

Tools & Resources


Guiding Principles

1. We have more to gain from working together. We commit to pooling our knowledge and collective power to have a greater impact. We are committed to educating ourselves so our actions are informed.

2. We work in partnership with the industry to develop solutions. We identify and invite willing and like-minded commercial general contractors to inform our focus areas.

3. We are purpose-driven and business-minded. We are driven to achieve net zero-impact construction, but we recognize that we must also present a compelling business case to our companies and clients.

4. We will maintain an attitude of integrity, transparency, and inclusivity. We recognize that collective power and action is attainable when our group is united.

"We’ve been working with Sustainable Construction Leaders nationwide, and the Bay Area group is a beacon for the rest of us. They’ve done an amazing job prioritizing the opportunities in this market and then rolling up their sleeves and getting sh*t done."
