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.

  • 63% of our worldwide server infrastructure is virtualized, leading to approximately 84 gigawatt-hours of energy saves annually. With a virtualization rate of 72%, Switzerland is the leading geographic location at the bank. 
  • IT server virtualization across all regions has resulted in a net increase in virtual server estate of 3 percentage points through 2016, up from 64% in December 2015 to a total of 67% in December 2016. This has led to around 1.1 gigawatt-hours power consumption reduction across the Enterprise Data Centers for 2016.  This achievement of decreased power utilization is further enhanced by the fact that the overall server estate grew by 4,040 servers in 2016, with the virtual server estate increasing by 4,119 servers and the physical server estate decreasing by 79 servers. If all 41,569 virtual servers were deployed as physical servers, there would have been an approximately 10,000-kW increase in power consumption. Juxtaposed against this number, Credit Suisse has been able to avoid an increase in electrical power consumption of around 87 GW/h in 2016.
  • Power save mode is being enabled every weekend on 1400 physical servers in APAC resulting in annual savings of 159 megawatt-hours. Following the successful APAC pilot project, this initiative is expected to be replicated in other locations.
  • Credit Suisse conducted a total of sixteen energy audits in accordance with article 8 of the EU Energy Efficiency Directive across offices in Italy, Luxembourg, Poland, Spain and the UK. These audits covered a total of around 140,000 square meters of office and data center space and have identified numerous opportunities for further energy savings in our building portfolio.  In addition to this, Credit Suisse has maintained Carbon Trust Energy Accreditation for the period 2016-2018, demonstrating an ongoing commitment to carbon management in the UK portfolio, which covers all operations and sites in the country.
  • In the framework of the energy efficiency program, we have continued to optimize energy consumption at premises used for operational purposes in Switzerland. In 2016, thanks to around 40 different measures across our building systems (heating, ventilation and air-conditioning), lighting and the building envelope, we have achieved a recurring increase in annual energy efficiency of 2 GWh. Overall, the measures implemented equate to a reduction in CO2 emissions of 384 tonnes a year.
  • The Credit Suisse branch in Solothurn was upgraded to the very latest technology in 2015/16. As part of this process, the existing building systems plant and equipment was updated. The building is now powered entirely by renewable energy. Heating is provided by the local district heating network, and the cold needed for air-conditioning the building comes from ground water. These measures have dramatically reduced the carbon footprint of the premises. Through more efficient building systems, around 24 MWh (10%) of energy is being saved annually. Connecting up to the district heating network is cutting CO2 emissions by 40 tonnes (62%) per annum.
  • In 2015/16, the building envelope of the Credit Suisse branch in St. Gallen was refurbished. In the course of the refurbishment, the insulation of the façade and the old windows were replaced. These two measures have cut the amount of heating needed at the premises by 309 MWh of fossil fuel and reduced the carbon footprint by 104 tonnes a year.
  • Faucet aerators have been installed on sink taps in the Credit Suisse Tower in Zurich. The water flow is approximately halved without any discomfort to the client while washing hands. The decreased volume of hot water needed leads to water conservation and energy savings. The installation of all sink taps in the building is expected to enable a water reduction of about 1'650 cubic meters and 35,000 kWh per year.
  • Credit Suisse UK received a certificate from the Carbon Trust, which provides independent certification to organizations with regard to their impact on the environment and their greenhouse gas emissions, in the United Kingdom. Certification requires good carbon management, including the accurate measurement of and a reduction in a company's carbon footprint. Credit Suisse UK was certified for a 12.1% absolute reduction of our Carbon footprint based on a two-year compliance period.
  • The refurbishment of our main office site in London has commenced. The project (named "Project Endeavour") will introduce a number of energy saving features such as efficient heating/cooling, LED lighting and ventilation and has achieved a BREEAM rating of "excellent". Other features include intelligent motor controls for elevators and water-saving WC fixtures. Enhanced energy metering and building controls will also be introduced to enable closer control of the internal environment and better tracking of energy use around the building. This project builds upon a number of environmental initiatives already implemented at the approximately 93,000-square-meter site, which houses 6000 staff, which has already reduced its consumption by over 10% in three years, a reduction in excess of 12,000 MWh.
  • Natural gas fuel cells producing a nominal 750 kilowatts (kW) of electricity have been installed at the Princeton Data Center. Leveraging the lower energy cost of natural gas, compared to equivalent units of electrical energy from the public utility service provider, the fuel cell electrical production helps offset the cost of electricity purchase while producing cleaner electricity than is locally available from the electricity grid. The fuel cell system is a long-lived machine with 20-year operating expectation. It is arranged to support an additional 750 kW of capacity expansion to be installed alongside the operating system without interruption.
  • Credit Suisse's long-standing partnership with Con Edison (a New York City utility company) and the New York State Energy Research & Development Authority (NYSERDA) continues with the application of energy efficiency and electrical demand reduction initiatives implemented as part of Project Liberty and Engineering Operations optimization.  Through Project Liberty's extensive renovation program, measures were taken to reduce energy consumption and electrical demand via: 
    • high-efficiency lighting design
    • occupancy sensor lighting control
    • variable frequency drive (speed control) of air-handling units 
    • high-efficiency technology cooling systems 
    • high-efficiency network switches
    • virtual desktop infrastructure 
  • The above measures have cumulatively earned USD 800,000 of incentives from NYSERDA and Con Edison as the efforts of Credit Suisse contribute to the reduction of the electrical grid demand and of electrical consumption.
  • The Production Data Center in Sydney was successfully migrated to a colocation facility. The Data Center was downsized both in terms of physical rack space (174 to 40 racks) as well as in terms of designed power capacity (203 to 80 kilowatt), with the ability to scale up or scale down the capacity as and when required. This increased the utilization from just below 40% to 76%, resulting in increased efficiency and utilization of available capacity.
  • The EON premises in Pune, India achieved LEED Platinum certification for commercial interiors in November 2016. The site, which is 35,400 square meters in size, was awarded 85 points, with 80 being the minimum for LEED Platinum certification.
  • The Changi Business Park (CBC) site, with a site area of 21,690 square meters, was awarded the Green Mark Platinum certification by the Singapore Building Authority in July 2016 for an additional 4,986 square meters that were certified. Assessment criteria included energy and water efficiency and green features and innovation.
  • An extensive program is being conducted to investigate various aspects of waste management at each of the Singapore premises, with a view to achieving improved and uniform recycling practices and procedures. Objectives and outcomes to date include the improvement of the recyclable waste storage process in the Changi Business Park (CBC), which is implemented in conjunction with the landlord, as well as the improvement of the visual cues for recyclable waste containers. Collectively, the Singapore sites occupy around 64,861 square meters of space, 160 kilowatt of stranded power capacity were eliminated in the Regional Data Center. This ensured that 16% of the previously unusable Data Center capacity can now be re-used for future installations, thereby extending the life of the facility as well as its efficiency, with the potential to now use the Data Center to the full design capacity.

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).
