While nations blow hot air, it’s cities that are the real sustainability heros
Though cities are responsible for about 70 per cent of global warming emissions, it’s a rare city that owns, regulates or reaps taxes, jobs or other benefits from oil, gas or coal reserves or many of the companies that spin off these resources.
As often as not, high emissions in cities are the result of subsidies and other practices embedded at the national level. Resource and allied companies (pesticide and fertilizer companies, for example) hold sway at the national, not city, level.
