In 2010, DZ BANK updated the existing standards to include new minimum social and environmental standards and integrated them into its purchasing processes. These provide a framework that lays down the financial, environmental, and social standards, for example related to human rights and working practices, needed for a supplier relationship to be sustainable. The standards apply to all entities in the DZ BANK Group. Since 2010, we have also been using a sustainability agreement that requires all suppliers to comply with DZ BANK’s minimum standards, the principles of the United Nations Global Compact, and the requirements of the International Labour Organization. In 2016, we did not identify any actual or potential adverse impacts of a significant nature on the environment, human rights, or society, or in regard to working practices.

Proactive supplier management provides the basis for DZ BANK’s sustainable procurement operations. For example, we classify suppliers according to their sustainability relevance for DZ BANK. Since the beginning of 2013, suppliers that are considered to be particularly relevant to sustainability because of the volume of orders we place with them, their specific activity, or country-specific risks have been asked more searching questions about the sustainability of their core business. These cover certification, approaches aimed at minimizing pollution, and other areas. We take reasonable steps to verify whether and to what extent our suppliers are meeting the sustainability obligations that are stipulated in their contracts. We base any further action to be taken on the data we collect. Since 2013, all of our suppliers’ sustainability performance data has been stored in a database. A breach of the environmental and social standards stipulated in the sustainability agreement may ultimately lead to a supplier being suspended.

Eco-friendly mail dispatch

Since May 2013, all German offices of the pre-merger DZ BANK have been using the eco-friendly GoGreen service from Deutsche Post DHL to send parcels and letters on a climate-neutral basis. In 2016, around 100 courier deliveries and 1,800 letters left DZ BANK every day and reached their recipients all over the world without a carbon footprint.

Discussions on sustainability issues

DZ BANK participates in various networks and specialist events in order to debate current trends relating to sustainability, such as environmentally friendly facilities management. One of the events that we attend every year is the annual Energy Talk run by utility company Mainova, where we can talk to other companies on topics such as energy efficiency for building shells and energy management systems. We also maintain close links with other skyscraper operators in Frankfurt. DZ BANK also takes part in local ECOPROFIT projects in its home cities of Frankfurt and Düsseldorf.

Highly efficient computing centers

DZ BANK uses two highly efficient computing centers at its Frankfurt offices that are fitted with the latest IT equipment to ensure its business operations run smoothly and securely. Covering approximately 1,000 square meters in total, they contain around 3,000 servers, none of which is more than five years old. The sites of the former WGZ BANK are being integrated into the existing IT infrastructure as part of a long-term process.

DZ BANK makes a concerted effort to pursue a 'green IT' approach so that it can reduce the negative impact of its information technology on the environment and climate. This approach particularly applies to electricity consumption: By making sure all the systems that we use are as efficient as possible, we keep the amount of energy we need to a minimum. Furthermore, the two computing centers have been powered solely by electricity from renewable sources since 2010. Their efficiency can be determined from their PUE rating (power usage effectiveness), which is calculated by dividing the amount of power entering a data center by the power used to run the servers that it contains. DZ BANK achieves a very good PUE rating of approximately 1.5.

Slight increase in electricity consumption in 2016

In 2016, we further expanded the capacity of the systems and server space at our Frankfurt offices in order to extend our use of virtualization platforms. This resulted in a slight rise in electricity consumption in the computing centers. Another reason for the increase of 150,000 kilowatt hours, in addition to the expansion of capacity, was the age of one of the computing centers. Now that this is reaching the end of its useful life, DZ BANK will be switching over to a new, modern computing center by 2018 that will further reduce power consumption.
