Nokia Siemens Networks CO2 footprint report

Scope

The Nokia Siemens Networks related CO2 footprint is based on Nokia Siemens Networks own operations according to the different emission scopes of the GHG protocol. However, the largest overall impact results from the use phase of Nokia Siemens Networks products and the energy source used for their operation, covered in the second part of this report.  

Direct emissions (scope 1 emissions) include emissions from fuel (gas and oil) usage in Nokia Siemens Networks facilities. The effect of greenhouse gases CH4 and N2O in burning gas for heating the facilities have also been converted to CO2e (CO2 equivalent) emissions. However, emissions from vehicles owned by Nokia Siemens Networks (service car fleet and management’s car benefit) are not yet tracked.

Electricity indirect emissions (scope 2 emissions) are based on reported emissions from Real Estate (electricity, district heating).

Other indirect emissions (scope 3 emissions) include energy from data centers located outside Nokia Siemens Networks premises, outbound logistics (transport of Nokia Siemens Networks products to hub delivery), traveling (Nokia Siemens Networks business travel based on flown miles) and the embedded energy of purchased components. The regional transport to final destination is not measured and packaging is not yet included. Supplier to factory deliveries will be included in 2010.

Footprint of own operations

We have improved the details and accuracy of our environmental reporting in recent years. Initially we covered real estate and traveling but since 2008 we have added logistics, Nokia Siemens Networks servers outside our own facilities and purchased components as an estimate of our supply chain. (We currently have no detailed footprint data from our supply chain.) The ‘Purchased components’ supply chain footprint figure is based on a life cycle assessment analysis of our key products and derived from the estimated lifetime footprint of our annual production volume.

NOTE: The reported figures in the diagram for 2007 are based on the 9 months of Nokia Siemens Networks operations plus estimates for the first 3 months of separate operations before the merger. The year 2006 is based on Nokia figures and estimates for the related Siemens operations. The years 2006 and 2007 are therefore relatively unreliable.

CO2 emissions have been reduced in all areas except Real Estate, where emissions have increased slightly as a result of relocations to Asia. This has been more than compensated with the purchase of additional “Green Electricity” in Finland and Germany, resulting in lower total real estate related CO2 emissions. Emissions from data centers and related IT activities from locations outside Nokia Siemens Networks’ premises are reported separately under ‘External data centers’. Emissions from portable equipment (laptops, mobile phones, home office connections, etc.) resulting from the use of that equipment during their operation outside Nokia Siemens Networks premises are not included. A rough estimate indicates that these emissions are small enough to be within the accuracy of the reporting.

Significant changes have been observed in particular in our travel footprint. The merger in the 2007 resulted in extremely high travel activities with an increase of about 80 percent compared to 2006. During 2008 we introduced travel restrictions, cutting travel related emissions. Further, during 2008 we introduced a more accurate method of travel emission calculation based on flown miles (previous years estimate based on travel cost 2). 

Traveling includes business trips booked via the Nokia Siemens Networks travel tool in Germany and Finland. Emissions resulting from travel originating in other countries are estimated based on those figures. It does not include emissions from other traveling like rail, boat or employee commuting. 

We signed an agreement with Deutsche Bahn (DB) in Germany to provide us with carbon neutral train journeys. This means DB buys renewable electricity for the tickets Nokia Siemens Networks travelers purchase, saving 149tones of CO2 and 150kg of nitrous oxide in 2009.

We support employees who want to work from home or remotely as this can significantly reduce the need for commuting. At the end of 2009, Nokia Siemens Networks had globally 5,483 employees with a home office connection and worked part time from home. Under the assumption that these employees on an average spend about 10 percent of the annual work days for business travels and about 60 percent of the remaining work days avoid commuting of an average roundtrip distance of 40km this saves around 3,600 tons of CO2 a year.

Product footprint

The calculation of the product lifetime energy consumption is based on the number of products delivered annually, their average power consumption and typical life time. 

Air travel emission factors are according to the GHG Protocol Initiative, GHG emissions from transport or mobile sources, version 2.0 / June 2009. In 2008, km data was gathered only from FI+DE so the total km estimate is not reliable and old GHG protocol emission factors were used. Based on flown miles we estimated emission reduction from air travel of over 20% based on reductions in FI+DE in 2009 compared to 2008.

In 2007 we also set a target for the annual product lifetime use footprint of all our products for the year 2011. This target was calculated based on our product power consumption roadmaps and an estimate of the telecom market development. Based on this energy figure a global CO2 emission target was calculated with the global average of CO2 emission from electricity generation of 0.51kg CO2 / kWh (source: IEA statistics 2007). 

However, as all products are operated with electricity the CO2 footprint depends directly on the electricity generation method. We therefore consider it as more appropriate and accurate to change to reporting product lifetime energy consumption rather than emissions.
