Why is this important?
The production, distribution, and use of pharmaceuticals accounts for around 25% of the greenhouse gas emissions produced by the health care sector. (1) For a typical medical organisation from the international aid sector, pharmaceuticals make up roughly 3.5% of their total carbon footprint, and 13% of the footprint of purchases. (2)
As populations age and the demand for prescriptions rises, these emissions are likely to increase further. (3) This growing demand emphasises the urgent need to adapt procurement practices to protect patient health while keeping emissions low.
What's the solution?
Reducing emissions from the procurement of pharmaceuticals involves integrating sustainability into the procurement process, selecting suppliers and materials that contribute to a greener supply chain, such as using renewable energy, and requesting detailed carbon footprint information at the item level. This will allow for informed decisions, favouring products with the lowest environmental impact.
Addressing over-prescription is also crucial. By implementing precise prescribing practices, emissions from the production, transportation, and disposal of unused medications can be avoided. By adopting these strategies, healthcare facilities can significantly reduce its carbon footprint.

Point of attention
One of the most effective levers for reducing emissions in pharmaceutical supply chains is the transition to renewable energy in the production process. Shifting to renewable energy could reduce emissions by 20% to 30% across the supply chain. (4)
Many drugs, especially specialised medications, have one or few suppliers so hospitals have little leverage to change the practices of pharmaceutical companies. Collaborating with other hospitals and pharmaceutical prescribers can add incentive and bargaining power to change these practices. (5)
Key actions
-
#1 Reduce overprescription
Minimise prescription of unnecessary medication. Studies show that 10% of the items dispensed in primary care were not needed, so critically evaluating the necessity of medicine can improve prescription practices and reduce emissions. (12)
-
#2 Use alternatives, where possible
Switch to alternative products or less emissive delivery options. For example, use less emissive anaesthetic gases or inhalers. (13)
-
#3 Prefer suppliers with a decarbonisation plan
Select suppliers with a decarbonisation strategy, preferably those that have their targets validated by the Science Based Targets initiative (SBTi). SBTi is a non-profit organisation that reviews corporate climate targets and provide validation to those that are aligned with the ambitions of the Paris agreement. (14) Question suppliers about their decarbonisation plans (renewable energy, process optimisation, etc.).
-
#4 Prefer suppliers that optimise their processes
Question suppliers on the measures they take to improve efficiency in manufacturing processes, e.g. continuous improvement of manufacturing practice, moving towards continuous manufacturing, increase electricity efficiency, solvent recycling and reuse, and applying green chemistry principles. (15)
-
#5 Prefer suppliers that use renewable energy
Select suppliers that are using renewable energy on their production sites. The use of renewable power can lead to a reduction of greenhouse gas emissions by 20-30% across supply chains. (16)
-
#6 Request product carbon footprints or LCAs
Ask suppliers to provide a product carbon footprint or a lifecycle analysis. Some advanced suppliers might already be able to supply the information. Use the information to identify decarbonisation levers and prefer suppliers that address them. The British Standard Institution (BSI) is in the process of developing a harmonised methodology to measure greenhouse gas emissions in the pharmaceutical sector. (17)
-
#7 Switch to less wasteful and emissive packaging
Work with suppliers to reduce the impact of packaging, where possible. Prefer reduced packaging and seek alternatives to plastic packaging. Consider primary and secondary packaging.
