Our approach to Environmental protection

Accelerating the delivery of sustainable, net-zero healthcare through science

We follow the science to lower the economic and environmental burden of healthcare and recignise the nexus between climate and health. Climate change, pollution and ecosystem degradation are already impacting human health – including through a rise in non-communicable diseases such as heart disease, stroke, lung cancer and respiratory diseases – and undermining the capacity of health systems.

Recognising the importance of working in partnership for a better future, we are one of 15 members of the Sustainable Markets Initiative Health Systems Task Force, chaired by our CEO Pascal Soriot, collaborating across the healthcare sector to accelerate the transition to net-zero health systems.

Bold climate action and investments in nature and biodiversity are vital to drive positive global health outcomes.

Our focus areas

Ambition Zero Carbon

Through our Ambition Zero Carbon strategy, we are pursuing ambitious science-based decarbonisation targets, accelerating our progress towards net zero, and managing the risks and opportunities presented by climate change. We are working to deliver net-zero healthcare, acknowledging that approximately 5% of greenhouse gas emissions are from the healthcare sector.

Product sustainability

People and the planet will benefit from those medicines which have the smallest possible environmental impact yet maintain the highest medical efficacy and safety standards. As technologies and healthcare systems evolve, so should solutions to reduce energy, water, material use, waste and pollution generated from designing, manufacturing and delivering medicines to patients.

Natural resources

We are taking action to protect and restore ecosystems by limiting environmental impacts across our value chain, investing in nature, biodiversity and water stewardship. The conservation and sustainable use of natural resources is vital to shape a healthy future with resilient people and communities, building harmony between society and the natural environment.
