1 The environmental performance indicators include all GF production companies.

2 Due to the implementation of a new Sustainability Reporting Tool, the historical data points have been consolidated and restated. The same GF company consolidation principles apply as in the Annual Report 2017.

3 The target line is calculated linearly based on the standardized baseline consumption (=100) and according to the defined target.

4 The production volume is defined based on the specificities of the businesses of the individual divisions: as “produced tonnes” for GF Piping Systems, as “gross value added” for GF Casting Solutions and as “hours worked” for GF Machining Solutions.

5 CO 2 -equivalents is a unit used to transform other greenhouse gases into CO 2 e (CO 2 =1) according to their global heating potential. The applied emission factors are based on the GHG Protocol 2016.
