Environmental protection

The climate emergency is an environmental and public health crisis. It is already changing our planet irreversibly, with warming reaching critical tolerance thresholds for human health and wildlife. We have an opportunity to ‘reset’ and create a more sustainable world for people and the planet – together and without delay.

Our approach to Environmental protection

We are focused on delivering net zero healthcare and working with our partners to achieve this. We’re also protecting the environment – by proactively managing our environmental impact across all products and activities, becoming more circular in our use of the planet's finite natural resources, and investing in nature-based solutions to support greater biodiversity.

In addition, we identify and manage risks and opportunities for our business to ensure continued resilience in the face of climate challenges and the transition to a low carbon economy. These are reported through the Taskforce on Climate-related Financial Disclosures (TCFD), with further information available here.


Ambition Zero Carbon

Through our flagship Ambition Zero Carbon programme, we are on track to eliminate greenhouse gas emissions from our global operations by the end of 2025. We also aim to become carbon negative across our entire value chain by 2030 and we are working with our partners to achieve this.

Our climate strategy is verified by the Science Based Targets initiative (SBTi), and we were one of seven companies globally to receive this verification in line with the SBTi’s world-first net-zero corporate standard in October 2021.

We are also an early supporter of the UN-backed Race to Zero. In addition, we were the first pharmaceutical company to sign up to all three of the Climate Group’s RE100, EV100 and EP100 initiatives, and in October 2021 we were one of only 17 companies out of over 500 global companies to have done so.

Our ambition

We will eliminate carbon emissions from our operations by the end of 2025 (Scope 1 and 2 greenhouse gas emissions).
We have committed to:

  • doubling energy productivity
  • using 100% renewable energy for power and heat
  • switching to a fully electric vehicle fleet
  • eliminating F-Gas emissions at our sites

We will become carbon negative across the entire value chain by 2030 (Scope 3 greenhouse gas emissions).
We have committed to:

  • transition to our next-generation respiratory inhaler with near-zero climate impact propellants
  • explore how to ‘design in’ sustainability across product lifecycles and embed net zero into the cost of goods
  • engage with our suppliers to reduce emissions in the network

Our achievements

60% reduction

in Scope 1 and 2 greenhouse gas emissions between 2015 and 2020
