The 2017 Sustainable LA Grand Challenge Energy and Air Quality Report Card for Los Angeles County offers an in-depth look at the region’s sustainability efforts focused on the energy we use, greenhouse gas emissions and the air we breathe. This report card assesses 21 indicators across five categories: stationary energy use, transportation, renewable energy resources, greenhouse gas emissions; and air quality and human health impacts. The grades range from C-/ Incomplete to B, and although there is progress toward meeting local and state goals, we are not quite there yet. Fortunately, there are a number of new standards and regulations that will undoubtedly have a positive impact in years to come.
