Low-emission steel has a 63% smaller carbon footprint than conventional steel. If manufacturer Siemens Gamesa used low-emission steel in all its wind turbine towers, it would be equivalent to taking 466,000 cars off the roads every year. Tower production accounts for one-third of the carbon footprint of wind turbines. That’s because steel manufacturing is highly carbon intensive It accounts for 7-9% of total global emissions. For every tonne of steel produced, 1.89 tonnes of CO2 are emitted
