Ed Begley Jr.
Environmental Activist
Emmy Award-Nominated Actor
Faced with growing environmental challenges, Ed Begley, Jr. exemplifies personal action by championing sustainability in Hollywood, serving on environmental boards, earning numerous accolades, and living in an eco-friendly home near Los Angeles.
As environmental issues become more pressing, there are two possible responses: forget it and hope that government and corporations will figure it out, or take action yourself.
In the “take action yourself” camp, a few individuals are leading the way. One such person in California is Ed Begley, Jr.
Turning up at Hollywood events on his bicycle, Ed has been considered an environmental leader in the Hollywood community for many years. He serves on the boards of The Coalition For Clean Air, and The Thoreau Institute.
His work in the environmental community has earned him a number of awards from some of the most prestigious environmental groups in the nation, including the California League of Conservation Voters, the Natural Resources Defense Council, The Coalition for Clean Air, Heal the Bay, Santa Monica Baykeeper, and the Cesar E. Chavez Foundation.
He currently lives near Los Angeles in a LEED Platinum home, rides his bike and takes public transportation.

Testimonials From Past Attendees
“The Green Media Summit, presented by Sharethrough highlighted the powerful intersection of advertising, sustainability, and the urgent need for systemic change to combat climate issues. There’s no doubt that addressing the climate crisis requires bold, ambitious action from the advertising industry.“
Growth Marketing Manager
“A pervasive theme at Sharethrough‘s Green Media Summit was working towards an ecosystem that rewards businesses making better decision about emissions. This is particularly critical for publishers who want to lean in but are (reasonably) weary of negatively impacting performance.“
SVP Programmatic Revenue & Strategy
“Thank you to the team at Sharethrough for putting on a fantastic event, with speakers that inspired climate action not just within the advertising industry, but also as a culture movement. I have no doubt that this gathering accelerated the drive in all of us to make our small corner of influence in the world a little greener.“
Director, Social Impact – Sustainability
“[The Green Media Summit] hosted a productive discussion on sustainability from the agency point of view. The event brought together some of the biggest names in the industry, including GroupM dentsu IPG Mediabrands Horizon Media and Publicis. Their collective insights and efforts towards sustainability are sure to bring about positive change.“
Vice President – Director Strategic Alliances and Partnerships
“The standing-room-only event showed the resolve of the ad tech community in the United States to come together and answer the call to create a greener ecosystem in the context of the global push toward net-zero greenhouse gas emissions.”
Director
“Amazing day at the Green Media Summit. Kudos to the Sharethrough team for putting together a great day of education around sustainability in media with a great audience. If you are serious about reducing your carbon emissions, this was a great day and our industry needs more minds thinking about this area. We do have a planet to save.”
CEO
“I signed up to today’s Green Media Summit with no real understanding of the connection between the ad industry and sustainability. In the first 5 mins I learnt that the carbon emissions generated by the internet are greater than the aviation industry 🤯 I walk away impressed and inspired at the industry’s self-led call to adopt standards and solutions towards net zero, with the likes of John Osborn and Ad Net Zero leading the charge.”
Strategic Advisor and Executive Attorney
“Great discussion this morning at the Green Media Summit with Brian O’Kelley from Scope3 and Michael Burgi from Digiday. Marketers have a financial problem and an environmental problem. It is very encouraging to hear leaders across the ecosystem talk about meaningful actions the industry can take now.”
CMO
