About Green Source DFW

Green Source DFW is an award-winning digital publication covering environmental news in North Texas. 

Launched in 2011, the educational site was created by the Memnosyne Institute, a Dallas-based nonprofit, to educate the community about environmental topics including green living, sustainability, conservation, environmental advocacy and public policy discussions.

Today, GreenSourceDFW.org continues to advance the North Texas green movement through original reporting, feature articles, green business and nonprofit listings, a green jobs board and a green event calendar and since 2019, a podcast called the Texas Green Report, aimed at a state-wide audience. In 2021, Green Source DFW launched a monthly Zoomcast called Green Source On the Air.


In 2019, the Texas Sierra Club honored GSDFW editor Julie Thibodeaux and GSDFW reporter Julie Ryan for environmental reporting. In 2018, Green Source DFW received the Media Accountability Award from the Dallas Peace and Justice Center. Prior to that, Green Source DFW was awarded the Green Media Award by the North Texas Corporate Recycling Association in 2012 and 2014.
