Ambition Zero Carbon


What is Ambition Zero Carbon?

We are taking bold action on climate because we recognise the connection between healthy people and a healthy planet. The COVID-19 pandemic has resulted in the greatest public health challenges of recent times, but the impact of the climate emergency has the potential to be greater still and is already changing our planet irreversibly.

Through our flagship $1 billion Ambition Zero Carbon programme we aim to:

  • Achieve net zero greenhouse gas emissions by maximising our energy efficiency, shifting to renewable energy sources, and investing in nature-based removals to compensate for any residual GHG footprint
  • Build resilience by managing the physical (sites, supply chain) and transitional (regulatory, market and product) risks and opportunities arising from climate change in the value chain through adaptation and business continuity planning



Our approach

We follow the science and focus our activity on delivering absolute reductions in all our direct and indirect GHG emissions sources across the value chain — Scopes 1, 2 and 3. We will reach our targets by:

  • Decoupling our energy consumption from business growth — achieving absolute reductions in total energy consumed and doubling energy productivity from 2015 baseline (EP100), through continued investment from the Natural Resources Efficiency Fund (see below)
  • Substituting 100% of site energy consumption with renewables (RE100) and maximising the share of additional sources of renewable electricity, for instance through on-site solar PV and off-site power purchase agreements (PPAs)
  • Transitioning 100% of self-generated and imported heating and cooling to renewables, maximising the share of additional sources of clean heating and cooling, for instance on-site technology and new off-site biomethane production
  • Reducing the emissions of our legacy fleet and switching to a fully electric vehicle fleet (EV100)
  • Transitioning to our next-generation respiratory inhalers with near-zero climate impact propellants
  • Engaging with our suppliers to reduce emissions in line with the science of climate change
  • Assessing and mitigating the physical and transitional risks to our business caused by climate change, integrate these risks into overall risk management processes and report on them through our TCFD report.

Pursuing a science-based climate strategy

Through our Ambition Zero Carbon programme we are on track to reduce greenhouse gas emissions from our global operations (Scope 1 and 2) by 98% by 2026 and halve our entire value chain footprint (from 2015 baseline) by 2030 on the way to a 90% reduction by 2045 (from 2019 baseline). Our emission reduction targets have been verified by the Science Based Targets initiative (SBTi) and we were one of the first seven companies worldwide to have our net zero, science-based Scope 1-3 targets verified under their new Net-Zero Corporate Standard. We were also an early supporter of the UN-backed Race to Zero.

Our Scope 3 footprint is more than 20 times greater than our Scope 1 and 2 footprint and our ambitions will only be achieved through close collaboration with our supply chain partners. This is why we have set the goal to maximise the share of our spend that is with companies with verified companies with verified SBTs, and we work closely with the SBTi and our peers to support the progression to a low carbon economy.

Our stories

Delivering on our renewable energy strategy
Since 2015, we have invested $130M in natural resource efficiency and renewable energy at our sites through our dedicated fund. We will always need some energy and we are committed to using 100% renewable energy sources to meet all our needs by the end of 2025. In 2021, we initiated a programme of work to look at how we can maximise the positive impact of our renewable energy use, with a focus on adding new renewable energy sources to the locations that we operate in.
