A new report takes an independent look at 27 North American Cities and rates their environmental performance. The US and Canada Green City Index reports on 9 key areas in urban sustainability; CO₂, energy, land use, buildings, water, waste air and environmental governance. Each city is provided with an environmental profile that examines in detail areas where the city excels or needs improvement. Although the report misses out in some key areas, namely food security and biodiversity, it provides plenty of interesting information.
