Environment Environmental Management

Environmental Management

Credit Suisse is committed to operating in an environmentally friendly manner. Energy consumption is the area in which we have the greatest environmental impact and is therefore one of the focal points of our efforts.

Environmental Management System

At Credit Suisse, we strive to continuously improve our environmental performance in order to make more efficient use of resources and to reduce our level of greenhouse gas emissions.

Our environmental management system, certified globally in accordance with ISO 14001, governs the relevant responsibilities, processes and operational measures within our company and globally encompasses all properties used for operational purposes by employees of the bank. Where appropriate, we also involve external service providers and suppliers in environmental management efforts. In 2015, we once again passed the re-accreditation audit of our environmental management system, which was carried out by the external certification company SGS.

Measures Taken in All Regions

We continued to implement concrete measures to reduce our environmental footprint in all regions, focusing on energy management, as energy consumption is the area in which our operations have by far the greatest impact on the environment.

  • Approximately 56.4 gigawatt-hours of energy were saved globally as a result of increasing our server virtualization rate to 61% worldwide over the past 5 years. In Switzerland, the virtualization rate reached 72% at the end of 2015.  
  • As part of the "Credit Suisse Cares for Climate" initiative, through which Credit Suisse is making an active and measurable contribution to climate protection, we again participated in Earth Hour in 2015. 42 Credit Suisse buildings globally took part in this symbolic climate campaign, during which thousands of cities, villages, and landmarks worldwide turned their lights off for an hour to make a statement on climate protection.
  • Upon renewing our contract with the external certification company SGS for the 2015-2017 period, we once again passed the annual SGS audit of our ISO 14001-certified environmental management system with no Corrective Action Request (CAR). The program included audits in Switzerland, Poland and the UK.
  • At Neue Aargauer Bank (NAB) headquarters in Aarau, we have replaced the building systems. Among other things, we connected to the heating and cooling network of local energy service provider IBAarau AG. The optimizations are expected to lead to estimated annual savings of around 745 megawatt hours (MWh) on fossil-fuel energy, reducing the consumption of primary energy by 691 MWh (69%) per year. This is expected to achieve a reduction in CO2 emissions of around 196 tons (87%) per year.
  • The operation of data centers not only requires energy for the IT equipment but also for the air-conditioning of the system rooms. In 2015, we optimized the cooling system in our Data Center in Horgen to save 497 MWh per year by increasing the proportion of free cooling. These savings are additional to those achieved through measures taken in 2012 and 2013, which already delivered electricity savings of 2,420 MWh per year relative to pre-2012 levels. Further savings potential to be exploited in the coming years lies in optimizing the operation of the chillers in the summer by lowering the re-cooling temperature.
  • In the new 2015 electricity supply contract for the Switzerland region, we have secured 100% of our electricity from certified hydropower (HKN) as a contribution to the "Substitution" path in our four-path "Credit Suisse Cares for Climate" strategy to achieve global greenhouse gas neutrality.
  • In view of Swiss energy legislation introduced in 2012, Credit Suisse defined a new Group target for energy efficiency in conjunction with EnAW, the Energy Agency for the Economy. Our aim is to improve energy efficiency by 2% per year in the period from 2013 to 2020 for our portfolio of operational premises in Switzerland.
  • We were able to secure attractive conditions for gas and electricity through new contracts with suppliers for our London Campus headquarters and the Slough Data Center in the UK, which have a combined space of approx. 93,000 square meters of usable space. These new three-year contracts cover the supply of around 75 million kWh of electricity and 3.7 million kWh of gas. The agreed quality requirements in the electricity contract guarantee the supply of 100% renewable energies through corresponding Renewable Energy Guarantees of Origin (REGO) certificates. This means that Europe, the Middle East and Africa are making another key contribution on the "substitution" path for implementation of Credit Suisse's climate strategy.
  • Throughout the region, we have achieved in excess of 8,000 megawatt hours (approximately 7%) of savings in electricity consumption compared to the 2014 actual consumption. This has been achieved partly due the consolidation of regional premises and building upon the energy initiatives that were introduced in 2013 and 2014. These initiatives included continuous commissioning of existing mechanical infrastructure and the selected isolation of redundant infrastructure. Our best-performing site (and one of the largest) in the region has achieved a year-on-year saving of 14%, through a combination of controls optimization, use of free cooling and reducing and/or using more efficient IT equipment within the building. This amounts to savings of CHF 1.2 million in electricity utility costs. All these achievements were driven by operational changes, without the need for any major capital investment by Credit Suisse. However some equipment, especially light fittings, was replaced with energy-efficient LED modules when the existing fittings reached the end of their life cycle.
  • Ten of our largest buildings across Europe, the Middle East and Africa, including sites in the UK, Poland, Russia, South Africa, Qatar, the United Arab Emirates, Saudi Arabia and Bahrain participated in WWF's annual Earth Hour 2015, where all non-essential equipment in the building is switched off for an hour to provide an example of the importance of conserving energy and resources.
  • Our London office campus now sends zero waste to landfills.
  • In September 2013, Credit Suisse signed a new 20-year lease to remain at Eleven Madison Avenue (EMA) in New York, and we are now in the midst of a multi-year, full-scale renovation of our offices.  This work has been designated as "Project Liberty".  The design and installation of the new floors incorporates energy-efficient concepts on the following building systems: 
    • Air Distribution – use of a variable air distribution in the open area offices. This system is more efficient than the existing system because it eliminates many small fan motors that were located around the floor, but still provides the same level of cooling.
    • LED Lighting – use of LED lighting along with a design that provides the optimum light levels with the smallest number of fixtures.  This is expected to reduce the operating cost per square foot from the previous lighting system.
    • Integrated Lighting Controls – a centralized lighting control system has been installed to gather energy use, control lighting levels and view occupancy. The system incorporates a network of motion sensors to utilize lights only in occupied areas. It can also sense daylight levels at the perimeter offices and reduce the amount of electrical light being provided during daytime hours.
  • In January 2016, the Singapore Regional Data Center consolidation plan was published. Work towards this densification initiative has commenced, which is ultimately expected to make available an additional 24 racks and 159 kW power maximizing capacity of our 1MW facility, ultimately removing the need for data center expansion in the near- to mid-term.
  • A number of initiatives were undertaken in the APAC region resulting in the optimization of our Data Center portfolio. In Pune (India), a 110 kW Data Center was eliminated, and in Singapore, the floor space occupied by the Main Distribution Frame (MDF) in One Raffles Link was reduced to a third.
  • In Singapore, our Changi City project received a Gold Green Mark Award from the Building Authority of Singapore (BCA), confirming its success in reaching substantial energy savings.

Involvement of External Partners

Where appropriate, we involve key external partners and suppliers when applying our environmental management system.

We draw up individual contractual agreements with our external partners to ensure they implement our standards, run our premises in an energy-efficient manner and actively strive to improve their own environmental performance.

We have defined guidelines to ensure that when we purchase goods or services that are of particular environmental relevance, our suppliers comply with progressive environmental standards and employment regulations. The guidelines focus on aspects such as the sparing use of raw materials, the careful handling of dangerous substances, the rejection of child labor and intentional discrimination, as well as the provision of competitive rates of compensation.

We expect our suppliers to comply with our Supplier Code of Conduct. In addition, a dedicated “Know Your Supplier” process has been established to identify and assess environmental, labor and social risks, as well as other risk aspects that may be related to the goods and services we procure. Selected requirements are:

  • Catering and cleaning firms: We once again defined annual targets governing energy and waste management, product ranges and employee training for the catering firms we use in Switzerland. We adopt a similar approach when working with cleaning companies; here, our focus is on the selection of cleaning products as well as their application.
  • Invitation for tenders for LED lamps: We defined energy efficiency targets, sustainability requirements and ergonomic criteria for the procurement of LED standard lamps as part of a pilot project in Switzerland.
  • Merchandising products: The environmental and social standards relating to all the products offered in conjunction with our Bonviva bonus program were reviewed by an internal specialist committee and fair trade products were added to the range.
  • Facility management: We updated the requirements for the management of our premises, installations and equipment in Switzerland.

4 Greenhouse gas emissions for 2013, 2014 and 2015 are based on net emissions, taking into account the composition of energy purchased from renewable sources. For the EMEA region, surplus hydropower certificates from the Switzerland region were taken into account in the electricity model. The gross greenhouse gas emissions for the EMEA region are following the DEFRA guidelines for the UK. The Scope 2 emissions are not yet following the new Greenhouse Gas Protocol Scope 2 guidelines from January 2015. In the course of the data collection for 2015 minor adjustments were made to 2013 and 2014 basic data sets.
5 For reasons of continuity the environmental data 2015 were calculated and reported according to the VfU Indicators Standard Version 2013. The total greenhouse gas emissions sum up to 240'270 tons (Scope 1-3). A parallel calculation under the new VfU Indicators Standard 2015 results in total greenhouse gas emissions of 230'650 tons. These emissions include 107'850 tons from purchased electricity qualities (Scope 2 Market Based Mix). Had this electricity been purchased without environmental criteria, an addtional 80'450 tons of GHG emissions would have been the result. The scope 2 emissions would then have added up to 188'300 tons (Scope 2 Location Based Mix).
