Responsible energy user that helps create a lower-carbon future

Energy and carbon

We want our stakeholders to trust that we are making a positive contribution to a lower-carbon future by cutting our energy use and carbon emissions, and developing innovative new products that help our customers and other industries do the same.

Metric Unit 2015 2014 Management comment Status
Primary energy consumption (steel) * million GJ (PJ) 2,205 2,221 Despite fall in the share of electric arc furnace production, total energy consumed fell due to energy efficiency improvements, as well as decrease in total steel produced. Met target/improved
Energy intensity (steel) GJ/t liquid steel 23.9 23.8 Reduction represents real energy efficiency improvements, especially in NAFTA. Did not meet target/deteriorated
Total CO2e emissions (steel and mining) million tonnes 205 203 Changes this year are primarily due to the increase in blast furnace and fall in electric arc production, following the slowdown in the construction sector. Energy efficiency achievements are more easily seen in the energy data. Did not meet target/deteriorated
Scope 1 CO2e (steel and mining) million tonnes 176 174 Did not meet target/deteriorated
Scope 2 CO2e (steel and mining) million tonnes 16 17 Met target/improved
Scope 3 CO2e (steel and mining) million tonnes 13 15 Met target/improved
Total CO2e emissions (steel)* million tonnes 198 195 Did not meet target/deteriorated
Total CO2e emissions (mining) million tonnes 7 8 This is in line with fall in mining production. Met target/improved
CO2 emissions per tonne* tonnes CO2 per tonne of steel 2.14 2.09 Actual carbon intensity increased due to the higher share of blast furnace production. Did not meet target/deteriorated

Towards a circular economy breakthrough: Our partnership with LanzaTech

This is a partnership to build the first plant in Europe to use the waste gases from steelmaking to produce ethanol on a commercial basis. This fuel generates 84% fewer greenhouse gas emissions than fossil fuels, and the plant will produce enough every year to run half a million cars. Every tonne of ethanol produced will reduce overall CO2 emissions by 2.3 tonnes and displace eight barrels (1 tonne) of gasoline.

The chemistry behind it is simple: steelmaking produces carbon monoxide as a waste gas, which is usually burned off, and CO2 is produced as a result. Finding uses for this waste gas, however, is much more of a challenge. Most steel plants use it to heat and power the production process, but where that doesn’t use all of it, the rest is burned off. LanzaTech’s pioneering new technology can recycle those waste gases and turn them into ethanol. This breakthrough recently earned LanzaTech the US Environmental Protection Agency’s Presidential Green Chemistry Award, the top award of its kind in the country and a Circular Economy award at the World Environmental Forum.

Construction of the €87 million flagship pilot project, which will be at our steelmaking site in Ghent, Belgium, has commenced and will start operations by 2017. It is too early to know whether this will prove successful on a commercial and scalable basis, but we are excited to be partnering with LanzaTech on this project.
