Energy savings: Heat homes, cool the planet

When it comes to energy efficiency, France is lagging behind its European neighbours, trailing Germany, Sweden, the United Kingdom and the Netherlands. Nearly seven million French people live in residences known as "passoires énergétiques" or energy sieves. These homes have an energy rating of F or G, meaning it's too cold in winter, too hot in summer and importantly, it adds considerably to the country's carbon footprint.
