New Zealand is greenest, the lowest ranked are Ethiopia, Mali, Mauritania, Chad and Niger.

The US is #28, well below Canada (#8). The accompanying press release notes that the US score "reflects top-tier performance on environmental health issues, but also indicates that the United States is underperforming on critical issues such as renewable energy, greenhouse gas emissions, and water resources."

The report purports to be data driven, but the weight given to environmentally questionable policy choices suggests some serious problems.
