1 The environmental performance indicators include all GF production companies.

2 Due to the divestment of the iron plant in Herzogenburg (Austria) of GF Casting Solutions as of 30 September 2019, the environmental performance figures are presented according to the consumption at this site while still part of the GF Corporation (9 months of 2019).

3 To ensure data consistency and comparability over time, the pro-rata 2018 data column shows how the comparable consumption would have looked like in 2018. In the calculation of the target-relevant environmental indicators for all the years in this overview, we applied the respective 9/12 ratio for the respective site.

4 The 2018 environmental performance indicators include the consumption of the two plants of GF Casting Solutions (Singen and Mettmann, both in Germany) while part of the GF Corporation (11 months of 2018).

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

6 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" (it includes all operating income substracting the costs of materials and products, changes in inventory, and operating expenses) for GF Casting Solutions and as "hours worked" for GF Machining Solutions.

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

9 Market-based emissions refer to specific emission factors, e.g. from local utility provider and they account for market instruments such as guarantees of origin that might be purchased in order to reduce Scope 2 market-based emissions.

10 Location-based emissions refer to the average emission factors of the area where the electricity consumption takes place, e.g. average emission factor of one country.

11 The reduction in the amount of waste disposal and recycling credits is mainly explained by the divestment of the mentioned sites of GF Casting Solutions in the years 2018 and 2019.
