The process of making steel has historically resulted in very high emissions of carbon dioxide (CO2). Every tonne of steel produces 1.8 tonnes of CO2, representing 9% of worldwide green-house gas emissions.
The good news is that over the years, we have made a lot of progress when it comes to the development and sustainability of material science. For example, if the Eiffel Tower was built today, it would only require 25% of the steel used for its original construction back in 1887.
We need to continue developing better ways to produce important metals such as steel for wear resistant plates and to better manage the materials that already exist today.
