Keynote Speaker: Darcy Paul (Cupertino Mayor)
Mayor Paul graduated from Harvard College, completing his pre-medical studies with a degree in Biology, magna cum laude with the highest honors in the field. At Harvard, he was Editor-in-Chief of the Harvard Journal of Undergraduate Sciences. Following college, he decided to pursue a career in the field of law following a year of conducting cancer research and teaching medical school admissions test classes to economically underprivileged and under-represented minorities in medicine. A graduate of Harvard Law School, Mayor Paul was Editor-in-Chief of the Harvard Journal of Law & Technology in his 3L year. Prior to being elected to the Cupertino City Council, Mayor Paul served as the President of the Board of Directors of the Cupertino Chamber of Commerce in 2014. On Council, Paul’s focus has been two-fold: first, upon ensuring equity and fairness in services and facilities; and, second, upon ensuring the integrity of constituent sentiment within the context of democratic governance reconciled with what are often-times competing, influential, and well-resourced stakeholders.

Second Speaker: Cherie Walkowiak (Cupertino Safe Routes To School Coordinator)
Cherie Walkowiak has been a Safe Routes to School Coordinator in Cupertino, and before that in Palo Alto, since 2017. Before that, she ran the community group Safe Mountain View for several years, where she advocated for road designs safe enough for kids to walk and bike around town. Her advocacy resulted in a separated bike lane in front of a middle school in Mountain View, a citywide policy to install separated bike lanes on roads with a speed limit greater than 30 mph, and the inclusion of studies of other important corridors into City plans. She also founded the community group Carbon Free Mountain View, where she advocated for what would eventually become Silicon Valley Clean Energy: an electricity provider that could provide 100% carbon-free electricity to most of Santa Clara County. Cherie is a mother of two teenagers, holds a single subject teaching credential from San Jose State University and a BA in Language Studies with a focus on French from the University of California at Santa Cruz. She loves to cook and is environmentally minded: conscious about reducing her family’s waste and carbon emissions. Her main mode of transportation is her cargo bike, and she delights in seeing how much she can carry with it.

Fourth Speaker: Gary Latshaw (Chair of Cupertino's Sustainability Commission)

Dr. Gary Latshaw will present the scientific basis for the man-induced warming of the world and the consequences of this warming: sea-level rise, more frequent and intense storms, droughts destroying crops, and other treacherous phenomena. The warming can be stopped and reversed, but that will require a transition away from traditional fuels and agriculture
techniques. Dr. Gary Latshaw received his doctorate in physics from Stanford University in 1971. Although his career primarily involved non-environmental issues, he maintained a serious interest in the environment and man-induced climate change over the years. Now retired Dr. Latshaw from working as a physicist in industry and colleges, he is a member of the Climate Reality Project and has become active in the Sierra Club,,, BACE (Bay Area for Clean Environment) and others. He now serves on Cupertino’s Sustainability Commission.
