In the midst of increasing press scrutiny of the bottled water industry’s environmentally harmful practices, FIJI Water made a series of sustainability promises. The boldest of these was a pledge to go “carbon negative.”

In mid-2013, Tesla Motors was riding a wave of success: It had launched its first really mass-produced car—the model S—to rave reviews, had recently raised first-year production targets, and had started taking orders for its next car, the Model X. Tesla seemed…

Iron ore + coal = iron + carbon dioxide. This chemical reaction, known long before the invention of the periodic table, is a key part of the steelmaking process and has helped build the modern world. But every tonne of iron generates more than two tonnes of CO₂, giving the iron and steel sector outsize importance in addressing climate change: it is responsible for one-tenth of global annual greenhouse gas emissions.

Greener methods are helping, such as recycling steel and producing iron in furnaces powered by natural gas, a somewhat cleaner fossil fuel than coal. Combined, they offer ways to reduce carbon emissions by as much as 70 per cent. These methods account for nearly a third of global steel production, with the remainder from coal-powered furnaces.
