BIG mainly focuses on what they can do to improve general sustainability problems and make the world a better place. However, I would love to read in more detail about how they as a company affect the environment negatively (actively or passively) and what they do against that.

It would be nice to have more concrete statements from Stakeholders or key employees on certain topics. The report sometimes seems like one big list of all the great things they’re doing and some statements could easen that up a bit and make it more authentic.

They could make the report a little more interactive. They have an amazing website dedicated solely to sustainability (Nachhaltigkeitsportal) and I feel like they could mention it more often, for example to reference to “further information”, interviews, downloadable content or such. It is only mentioned in the introduction!

When describing the organizational structure that has been set up for sustainability management, for most people it is helpful to have a visualization or a more detailed description than just a paragraph. It is the basis for working sustainably after all.

When it comes to the supply and value chain, the BIG should elaborate that topic a lot more in the report. The company could visualize and describe the value chain more in detail, like Lenzing AG for example.

To be more authentic the company should also analyze their figures and be more transparent regarding negative experiences or outcomes and what they learned from that.

BIG wants to convey an urban and modern image for the reader of the report, but they did not provide any online features or interactivity features in this report. This would be a positive add-on.

Contact Person: There isn’t a contact person included, why? Organizational structures and people, who are responsible for sustainability must be mentioned, otherwise it appears like a pr-text and even they have contact numbers

Utilize Online features: Cross-References to website could be linked, content could include hyperlinks to actual pages as well, GRI standards have page-references could be linked too, so no scrolling would be needed

Value Chain: Value Chain in construction industry is really important, as the company has to buy materials, needs investors. The report misses a clear overview, reader needs to gather and make his/her own big picture

Include NGOs in report: As they want to surpass sustainability standards, one way to catch the reader’s attention would be highlighting co-operations with NGOs better, BGI could name them and give them some spotlight in the report itself

The concrete process of SH engagement could be more transparent, w. e.g quotes of most important inputs from SH & frequency of certain topics SH mentioned, etc. This would enhance transparency & would make clear how the perspectives of intern./extern. SH merge w. each other ( not just different colors in the matrix).

Need to highlight more the material topics (just like they do it with the BIG 10 pts.) w. more measurable/ decisive objectives, appropriate KPIs. Need to mention them throughout the report.

BIG definitely is on the right track but needs to involve more in future aspects. Could identify more SDGs/mat. topics relevant for contributing to unsolved problems (positive impacts). For this they could cooperate w. NGOs.

BIG should give CSR report even more importance as a platform: Exposing relevant information (e.g. processes of sustainability mgmt.) in more detail - graphs could help here. Should highlight more its efforts to maximize positive impacts throughout the report (Hektar Nektar only mentioned at the end of the report).
