For an increasing accuracy of the calculations, it is necessary to continuously expand and refine the data collection. After calculating the first Corporate Carbon Footprint (Scope 1 and 2), it was decided in 2016 to also include emissions from Scope 3. The calculation of these emissions is linked to a higher complexity, as all indirect upstream and downstream value chain emissions (relevant, indirect emissions) have to be considered. At the same time, the carbon footprint should be broken down according to the company locations. Again, DFGE was able to deliver results in a timely way, making use of the DFGE Top Down Approach, which give a more detailed view on Greif’s emission sources. However, reductions in greenhouse gas emissions were not the only sustainability field Greif was active in during the last years: in order to frame all the various sustainability activities in a structured way, Greif decided to create a sustainability report. This is the reason why Greif decided in 2017 – after consultation with DFGE – to join the UN Global Compact (UNGC) and therefore to publish an annual sustainability report (COP – Communication on Progress).
