Los Angeles Mayor Eric Garcetti last week named Global Green CEO Matt Petersen as the city’s first-ever Chief Sustainability Officer. Peterson, according to the mayor’s office, will be tasked with “making the city’s departments greener and neighborhoods healthier, and fulfilling Garcetti’s campaign promise of creating 20,000 new green jobs.” Peterson should also have his hands full, not only getting each city department to cooperate, but on thorny issues like regulation of the city’s ports and transit corridors.

Global Green, if you’re wondering, is a non-profit dedicated to “advocating for smart solutions to global warming including green building for affordable housing, schools, cities and communities that save money, improve health and create green jobs.” Since its founding almost 20 years ago it has organized design competitions, testified in congress,  hosted awards, and raised money on behalf of green causes.
