It is an honor to serve on the Sierra Club San Diego Chapter’s Executive Committee. I have committed my life to conservation, habitat restoration, environmental justice, and climate action, and I believe I can make a meaningful contribution to the Sierra Club’s work here in San Diego and across the State.

Diego River Conservancy Governing Board. I’m also a Director of the Resource Conservation District of Greater San Diego, a member of the Volcan Mountain Foundation Stewardship Committee, and a Trustee of the La Jolla Town Council.
I live with my wife and two children in my hometown of La Jolla, where I am Director of the Sequoia Foundation, a nonproft social science research firm dedicated to studying the socio-economic impacts of environmental
disasters. I believe I can effectively represent members throughout San Diego County, leverage my extensive relationships to advance Sierra Club’s conservation agenda, and help to wisely guide our organization’s long-term development.

David RousseauExecutive Committee Member
I’ve been concerned about the environment ever since I participated in the first Earth Day as a high school student. I’ve always loved nature, and being outside, and my awareness of the impact of human activity increased significantly when I took the Wilderness Basics Course in 2002. I’ve been on the WBC Staff ever since, even serving as Chair for two years and writing the Prolog in the latest issue of the WBC textbook.
I’m especially concerned about the ever-increasing environmental devastation caused by the fossil fuel and plastics industries, and the complicity of our politicians. When I recently learned about new technology that can cleanly recycle 95% of all plastics, even plastics “contaminated” by food waste or marine growth, I got involved with the Chapter’s Conservation Committee and Zero Waste Subcommittee. I’ve taken the lead in exploring the feasibility of this new
technology for our region, and introducing it to the city recycling office and some of the local recycling companies, to find a way to get it up and running here.
As a retired aeronautical engineer for the Navy and Marine Corps, I’m undaunted by energy and environmental technology, and I’ll push for solutions that actually work.

Karl AldingerConservation Organizer
I am extremely excited and honored to join the Sierra Club team as we strive for the best solutions to challenges facing our climate and our environment. I graduated university with a degree in Electrical Engineering, and I’ve worked as both a software engineer and as a public school teacher. I have lived in Fallbrook since 2001, with my wife Marie-Pierre, who just finished Sierra Club’s Wilderness Basics Course, so I imagine backpacking is in my near future. Having volunteered with San Diego 350, the North County Climate Change Alliance, and as an organizer with the Sunrise Movement, a group grounded in Climate and Justice solutions, I have shifted my life’s work, because our world’s circumstances demand it. My focus at Sierra Club will be on improving Transportation Solutions, adopting Community Choice Energy, and maximizing Building Electrification and Efficiency. I very much look forward to working with all of you, building our community of advocates and pushing for better policies.
Steering Committee Goals
The Sierra Club Board of Directors on February 21, 2014 established the following goals for the Sierra Club San Diego Steering Committee and other Club leaders working with members of the Chapter:
Rebuild Sierra Club functions in San Diego and Imperial counties and transition to a well-functioning, effective member-elected San Diego Chapter volunteer leadership. This will include establishing new group norms to build trust among volunteer leaders, maintaining intellectual honesty and respectful dialogue, addressing disagreements constructively, and establishing a governance structure that engages people in work that advances the Club’s mission.
Provide support to improve Chapter volunteer leadership and management capacity to engage in addressing potential problems before they evolve into conflicts and constructively resolve disagreements.
Build the capacity of the San Diego groups, sections and committees to engage members and supporters in meaningful ways to advance Club goals.
Build a mutually beneficial relationship with the national Sierra Club.
Maintain the core functions of the Chapter: advancing the Club’s mission (conservation, litigation, and political), providing service to members, supporters and the public, building local resources, and complying with policies and standards.
Ensure compliance with applicable Club policies and requirements.
