350 Silicon Valley is a California-based child organization of 350.org, a left-of-center environmentalist organization that advocates for the complete elimination of conventional energy use.
350 Silicon Valley advocates for the Green New Deal and legislation that increases spending on infrastructure for a complete transition from conventional fuels to environmentalist energy. This includes so-called “climate justice” requirements that would invest in ethnic minority communities and prioritize the hiring of ethnic minorities in government-contracted infrastructure spending. 
350 Silicon Valley has also advocated for divestment from traditional fuels at the personal, corporate, and government finance levels. This includes city pension funds, 401(k) plans, and university investments. 
As an extension of conventional energy divestment advocacy, 350 Silicon Valley has campaigned for legislation to pass “Reach Codes.” “Reach Codes” are building codes that have been introduced within local California municipalities to require the use of environmentalist-friendly energy in new construction projects and for computer server industries that have high energy consumption. 
Volunteers for 350 Silicon Valley work in coordination with other environmentalist groups to support environmental legislation at the state and federal levels. For the 2019-2020 legislative session, 350 Silicon Valley supported legislation that would place restrictions on conventional energy businesses, increase funding and planning for environmentalist energy infrastructure, and ban single-use plastics. 
Nicole Kemeny is the board president for 350 Silicon Valley. She has worked on several environmentalist organizations such as the Sierra Club and worked in fiscally progressive housing policy advocacy. 
350 Silicon Valley is registered as a 501(c)(3) nonprofit organization. Its financial data is not publicly available as it reported less than $25,000 a year in gross receipts.
