Abigail Dillen is the President of Earthjustice, leading the organization’s staff, board and supporters to advance our mission of using the courts to protect our environment and people’s health. She is based at headquarters in San Francisco, California.

Before stepping into her current role, Abigail served as the Vice President of Litigation for Climate & Energy, heading the organization’s litigation and legal advocacy to achieve the essential shift from fossil fuels to 100% clean energy.

Prior to that, Abbie was managing attorney of Earthjustice’s Coal Program, which has played a central role in forcing the overdue retirement of coal-fired power plants around the country.

Abbie has litigated precedent-setting cases that have held polluters accountable and cleared the way for clean energy nationally. These wins include: requiring the U.S. Environmental Protection Agency to promulgate first-ever standards to govern disposal of coal ash and limit the wastewater discharge of toxic pollutants from coal-fired power plants; blocking a $2 billion transmission project to transport dirty coal energy from the Ohio Valley to East Coast cities; blocking permits for new coal-fired power plants; and cutting off federal funding of new coal plants.

Abigail came to Earthjustice in 2000. Working first out of our Northern Rockies Office in Bozeman, Montana, she worked to protect public lands and the many imperiled species that depend on them, including wolves, grizzly bears, and native trout.

Abigail received her B.A. from Yale University and her law degree from the University of California, Berkeley, where she graduated Order of the Coif.

Digging Out of the Money Pit to Create a Smart Grid

Our aging electric grid is in need of a major renovation to deliver electricity reliably into the next century, and one way or another, that overhaul will cost us a lot of money. The question is whether we throw more money at propping up the old architecture that is designed to deliver electricity from big fossil-fuel fired power plants, or make the forward-looking investments necessary to harness the clean energy that our future requires.
