Environmental Trends

CSL’s environmental performance is particularly important and relevant to select stakeholders and key environmental aspects including energy consumption, emissions, water use and management of waste can be found on page 35 of our 2019/20 Annual Report.

In addition to data stated in our latest annual report, CSL has collected data related to Scope 3 emissions (those emissions occurring offsite and not included as part of Scope 2).

Scope 3 GHG Emission Trends1

2019/20’s data comprises an estimated 35 KT emissions resulting from business travel and an estimated 48 KT emissions from plasma, intermediates and product transports, which are not included in prior years. The travel restrictions imposed by COVID-19 in the first quarter of 2020 led to a reduction of travel emissions of approximately 12% or 5 KT from 40 KT in previous reporting period to 35 kt in current reporting period.

1 Total GHG emissions from business air travel for CSL’s manufacturing sites at Bern (Switzerland), Lengnau (Switzerland), Marburg (Germany), Kankakee (US), Parkville (Australia), Broadmeadows (Australia), Liverpool (UK), Holly Springs (US) and CSL Plasma, CSL Behring headquarters (US), Seqirus headquarters (UK) and CSL’s affiliate sites.

2 Emission from air travel were calculated for the 1 July 2017 to 30 June 2018 period. To adjust for the new reporting timeframe work data for the Apr17/Mar18 period were calculated by adding 25% of FY16/17 and 75% of FY17/18 emissions.

3 Travel data were compiled from travel agency reports with varying degrees of detail. For consistency reason, booking or invoice date was used for calculation, because actual travel date was not available in some reports. Due to an inability to reconcile business air travel cancellations resulting from COVID-19 travel restrictions, Jan to March 2020 emissions data is likely to be higher than actual. Overall reduced booking Jan to Mar 2020 and non-trackable deletion of non-performed travels led to travel emission reduction of 12% or 5 kt compared to previous reporting period.

4 Data also includes emissions resulting from the transport of plasma, intermediates and products to the country of use, but not final distribution of products in the country of use. Due to varying levels of detail in the reports provided by logistics providers, pre- and post-carriage transport emissions could neither be verified in detail, nor could completeness of pre- and post-carriage emissions be ensured for all transports. Data includes transportation of product from the production sites Wuhan (China) and Lengnau (Switzerland).

Energy Efficiency

Examples of energy efficiency case studies across our organisation include:

Bern, Switzerland

Marburg, Germany

Parkville, Australia

We strive to reduce the environmental impact of our operations through innovative and smart processes, bysystematically saving resources and emissions and increasing reuse, recycling and awareness.

One project to achieve this vision was the replacement of three 27-year-old process steam boilers and the decommissioning of two combined heat and power plants. Steam is mainly used for various heating purposes during the production process largely for sanitization, the distillation of water for injection (used as excipient and for cleaning) and recovering of ethanol (used for the fractionation process)

In addition to improved efficiency of the steam system, equivalent to 980 tonnes CO2-e reduction per year, further advantages of this project are the future delivery of steam for Bern’s two new immunoglobulin modules currently under installation at Bern, and vastly improved redundancy of the steam system.

 

For the new base fractionation facility at our Marburg site, which is planned to start operation in the third quarter of 2021, an energy efficiency design was established which was an integral component of the building’s development.

On implementation a yearly CO2-emission reduction of 830 tonnes is expected, with the primary energy demand for the facility estimated to be 48% lower than required.

Design elements include a reduction in the water heating temperature from 80°C to 50°C. This allows more than 90% heat recovery of the heat from production processes and refrigeration systems to support heating needs of the building, to highly efficient state of the art HVAC and refrigeration systems reducing energy consumption and resulting emissions. The building also incorporates manufacturing process water recovery and reuse which reduces freshwater demand.

The KfW Energy Efficiency Programme (Reconstruction Credit Institute) promotes and supports construction of sustainable building with high energy efficiency in Germany. The KfW Group is funding the new base fractionation facility at Marburg with 250 Mio €, being one of largest funded within Germany.

 

An existing refrigeration unit at the Parkville site was replaced with a new much more efficient state of the art model.The controls for the chilled water system were modified to integrate the new chiller and manage load balancing of the two chillers in optimal energy efficient range.

The new chiller will reduce site emissions by approximately 1,300 tonnes CO2-e per year.
