Why was it done?

It is estimated that medicine contribute 20% of the Danish regions total CO2e emissions. Amgros and the Hospital Pharmacies of Denmark are committed to develop carbon reduction initiatives to assist the regions CO2e reduction strategy. It is essential to identify the main contributors of CO2e emissions in the lifecycle of a drug to support CO2e reduction.

What was done?

The Danish procurement organization Amgros I/S is responsible for buying medicine for Danish public hospitals. As part of the ambition for sustainability, The Capital Region Pharmacy (RAP) in collaboration with Amgros has made a bottom-up hotspot life cycle analysis (hLCA) of the carbon-footprint of morphine in tablets and solution for injection. The hLCA identified the main CO2e emission factors from API/excipient production to administration of the drug.

How was it done?

The energy consumption of the production processes was mapped at RAP. Five reference flows were modulated (tablets in three types of primary packaging and solution for injection in two types) and reported. The hLCA data for the API was extracted from literature while data for the excipients and packaging material were calculated using Ecoinvent. Ecoinvent is a life cycle inventory database used to support environmental assessments of products and processes.

What has been achieved?

The preliminary conclusion of the analysis shows the largest CO2e emissions per DDD originates from administering the drug due to the use of single-use materials.
Leaving out administration of the drug, the main CO2e emissions from tablets are API production and packaging materials. Packaging materials are the main CO2e contributor for the solution for injection.
The end report of the LCA was available, end of autumn 2023.

What next?

The hLCA’s are being used internally in Amgros to develop criteria for tenders. The hospital pharmacies can use the hLCA calculations to identify key subprocesses where reduction of the CO2e footprint is greatest.
The results contribute to:
• Danish hospital pharmacies better understand the CO2e emissions when prescribing and administering medicines
• Dialogue with the pharmaceutical industry about their CO2e emissions hotspots
Finally, the results will hopefully encourage other countries to incorporate environmental criteria in future medicinal tendering process for medicines.

EAHP Forum

All the EAHP team is working on providing a Forum that can help connect all the members in Conversations and Groups to talk about important matters for the European Hospital Pharmacist.

The Forum will be accessible for all the EAHP members, you don’t have to create a new account to browse and participate.

Conversations and groups

The Conversations will be moderated by our team to provide documents and relevant topics for the community.

The Groups will connect all members that share a category. Members who work on the same assocation, on the same hospital, that have the same role, etc.

Stay tuned for the realase of the forum. Soon on EAHP.
