SUSTAINABILITY-ENVIRONMENTAL IMPACT DATA
At Ovako sustainability and reduction of our environmental impact is a major focus in everything we
do.

To get the full picture of our products environmental impact we have to look at all of our CO2 emission
sources.
Not only the steel work Scope 1-2 itself, but all operations downstream in our production, heating and
heat treatment furnaces etc (full scope 1-2) as well as all the emission from input material, eg. alloys,
scope 3.
