His work focuses on accelerating deployment of clean energy in California and avoiding new investments in fossil fuel infrastructure. Matt’s areas of expertise include utility procurement, local reliability need, rooftop solar tariffs, rate design, energy storage, renewable integration, and decarbonization trajectories.

Matt has successfully opposed new proposed gas plants and pipelines, exposed gas utility obstruction of climate progress, and advocated for policies to transition away from gas combustion in buildings to safer, healthy all-electric homes.

Prior to joining Earthjustice, Matt worked on clean energy-related advocacy at the Sierra Club and at the Center for Biological Diversity where he developed the law and policy related to the analysis of greenhouse gas impacts under the California Environmental Quality Act.

Matt was also a Peace Corps volunteer in Paraguay where he worked with local farmers on sustainable forestry practices, learned to speak Guarani, and developed an addiction to yerba mate that persists to this day.
