The Society of Environmental Journalists is the only North-American membership association of professional journalists dedicated to more and better coverage of environment-related issues. SEJ’s mission is to strengthen the quality, reach and viability of journalism across all media to advance public understanding of environmental issues.
SEJ is an independent, nonpartisan educational association dedicated to the highest standards of public service journalism. SEJ’s 2012 operating budget of $864,369 (audited figure) was underwritten by foundation grants, dues, fees, university and media company sponsorship and unrestricted gifts up to $15,000 from any source.
The organization was founded in 1990 by award-winning print and broadcast journalists on staff with The Philadelphia Inquirer, USA Today, National Geographic, Turner Broadcasting/CNN, Scripps Howard News Service, Minnesota Public Radio and others. SEJ’s membership now includes more than 1,500 highly qualified journalists, editors, educators and students working in print, broadcast and online news media throughout the U.S., Canada, Mexico and 27 other countries. Members and others who use SEJ services report environmental news and information to millions of readers, listeners and viewers worldwide, on a daily basis.
In 2010, SEJ was co-winner of the Gulbenkian International Prize,  which distinguishes an individual or institution "whose thoughts or actions make a decisive contribution to and have significant impact on understanding, defending or fostering the universal values of the human condition."
SEJ established a Diversity Task Force  in 2010 to foster and promote greater coverage and understanding of environmental issues that affect minority and other marginalized communities.
