The context: Fuelled by a growing population and rising wealth, the number of cars and factories in and around the city swelled in the 1990s and 2000s. By 2013, concentrations of fine particulate matter (PM2.5) reached an average of 89.5 μg/m³, which is 18 times the World Health Organization’s recommended safe limit.

That heat can then be used by nearby households or manufacturers, or converted back into electricity when needed.

A growing number of US states have set stronger standards than federal regulations to curb methane emissions from landfills, and they’re creating something of a “domino effect” that’s spurring action across the country, according to a new analysis by non-profit think tank RMI. The context: Because they contain huge volumes of decaying food scraps and other organic waste, landfills are major sources of methane, a greenhouse gas that traps 80 times more heat than carbon dioxide over the near term.
