In St. Louis alone, 77% of the greenhouse gases are produced by municipal, residential, industrial and commercial buildings. The impact on air quality greatly affects everyone, but especially the children. The City of St. Louis wants their residents, workers and visitors to breathe easy in their flourishing city. The City found experienced partners in the City Energy Project, a joint IMT/NRDC effort focused on improving building energy efficiency. And since you can only manage what you measure, the City launched an energy efficiency benchmarking project in 2017 for their largest buildings.
