Over the past two years, entrepreneurs, developers and government agencies have collaboratively explored the power of open data to improve health or transit data as open government fuel for economic growth. Now, the Environmental Protection Agency (EPA) is looking to do the same with an Apps for the Environment challenge.

This Thursday at 4 PM EST, the EPA is hosting a webinar for developers to hear more from the community about what the government can do to make data more usable by developers. (Heads up, government folks: Socrata’s open data study found progress but a long road ahead, with clear need for improvement: only 30 percent of developers surveyed said that government data was available, and of that, 50 percent was unusable.)

I look forward to moderating the EPA webinar (register here) on Thursday. Listeners can expect to hear more about collaborative innovation in open government, crowdsourcing and challenges, and the sustainability of apps contests before we open up the discussion with Jeremy Carbaugh of Sunlight Labs and Michaela Hackner of ForumOne, the developers of DataMasher, the winner of Apps for America2.

If you’re interested in a different kind of public service through code, please tune in.
