Our Mission

Women in Cleantech and Sustainability (WCS) fosters an influential network of professionals to further the roles of women in growing the green economy and making a positive impact on the environment.

Our Story

Founded in 2011, WCS is a nonprofit 501(c)6 organization made up up nearly 3,000 professional women and men building the green economy.  Our members range from the students and entry level professionals, to Founders, C-Suite executives and investors.

Lisa Ann Pinkerton founded WCS in 2011, to create a Bay Area community to give women a sisterhood to thrive in and spotlight the remarkable women (and men) whose work is building our future green economy.

By 2013, WCS was officially established as a nonprofit 501(c)6 organization and a board formed to grow the organization beyond its early stages.

In 2014, the first WCS Talks was held. The TED-style conference established a top tier stage for women to share their professional stories, career tips and industry expertise.

In 2016, the Jobs Board and Mentorship programs were established to further foster WCS members on their career paths.

In 2018, WCS Talks held the first female-focused pitch competition for early-stage startups at WCS Talks.

Today, WCS is home to over 5,000 community members internationally, with local chapters in the San Francisco Bay Area and Los Angeles. Our members consist of all genders and range from the students and entry level professionals, to founders, C-Suite executives and investors.

WCS aims to meet once a month to network and learn the latest industry developments, as well as attain new business and personal skills from speakers and panelists. Topics covered include: renewable energy (solar, wind biofuel, etc), water, smart grid, biomass, carbon reduction, sustainable transportation, energy efficiency, sustainability, green buildings and many other technologies that aim to make our world a cleaner, more sustainable place.
