The ratio of carbon dioxide produced, relative to steel produced, is surprising. The bigger surprise is how to improve that ratio:

The Promise of Carbon-Neutral Steel

A new manufacturing technique could drastically reduce the footprint of one of our dirtiest materials.

Steel production accounts for around seven per cent of humanity's greenhouse-gas emissions. There are two reasons for this startling fact. First, steel is made using metallurgic methods that our Iron Age forebears would find familiar; second, it is part of seemingly everything, including buildings, bridges, fridges, planes, trains, and automobiles. According to some estimates, global demand for steel will nearly double by 2050. Green steel, therefore, is urgently needed if we're to confront climate change.Continue reading "Green Steel On The Horizon"
