As the CEO for the Leonardo DiCaprio Foundation, Terry Tamminen oversees the grant partnerships, which range from major environmental conservation organizations to local partners who are fighting to protect and defend vital ecosystems and species that are gravely impacted by the global environmental crisis caused by climate change. From his youth in Australia to career experiences in across the globe, Tamminen has developed expertise in business, farming, the environment, and the arts. Governor Arnold Schwarzenegger appointed him Secretary of the California Environmental Protection Agency and later Cabinet Secretary, the Chief Policy Advisor to the Governor, where Terry was the architect of many groundbreaking sustainability policies, including California’s landmark Global Warming Solutions Act of 2006, the Hydrogen Highway Network, and the Million Solar Roofs initiative.

In 2010 Terry co-founded the R20 Regions of Climate Action, a new public-private partnership to implement measurable, large-scale, low-carbon and climate resilient economic development projects that can simultaneously solve the climate crisis and build a sustainable global economy. An accomplished author, Tamminen’s books include Cracking the Carbon Code: The Keys to Sustainable Profits in the New Economy.
