Stable emissions intensity

During 2016, our own GHG emissions (Scope 1 and Scope 2) increased at a similar rate as our production volumes, leading to a globally stable emission intensity across Constellium (see graphs above).

Defining our GHG emission target across the full life-cycle of our products

Measuring our own emissions, however, is not sufficient to describe the impact of our activities. There are two reasons for this.

Firstly, our product mix is moving towards more energy-intensive products such as automotive body sheet. These products help to decrease GHG emissions during their use, due to savings in mass (see our LCA studies on automotive products for more details).

Secondly, we are increasing our recycling capacity. Using recycled aluminium reduces the need for primary aluminium, and significantly reduces GHG emissions. However, it also increases our own emissions for the same quantity of products shipped because the impacts associated with recycling and casting operations become incorporated in our own figures.

Therefore, we are currently working to define a target that takes into account the full life-cycle of our products.


    Scope 1 includes direct emissions from our sites.
    Scope 2 relates to emissions associated with the production of the energy we purchase
