Trelegy: Now a carbon neutral triple therapy inhaler, as certified by the Carbon Trust.1

One part of delivering GSK’s commitment to have a net zero impact on climate and net positive impact on nature by 2030.


As a science-based healthcare company, addressing our environmental impact is fundamental to our purpose, so that together with our partners, we can help protect and restore the planet’s health.

What does it mean to make a product carbon neutral?

Hydrofluorocarbons contained in pressurised metered dose inhalers (pMDIs) are potent greenhouse gases and have a high Global Warming Potential (GWP). Dry powder inhalers (DPIs) don’t contain hydrofluorocarbons, however, it doesn’t mean they don’t have an impact - almost everything we do as humans has an impact. We have, and continue, to innovate in our manufacturing and distribution of Trelegy Ellipta to make it’s footprint on humanity as low as possible - but now we have taken one step further and offset the carbon footprint it does have. This means compensating for the remaining footprint by removing the same amount of greenhouse gas from the atmosphere. With this process, we have made the inhalers carbon neutral.

How have we achieved it?

To offset the carbon footprint Trelegy Ellipta has, we are supporting a community re-forestation project based in Ghana - a project planting trees and improving sanitation and health.

This project restores forest reserves that have been degraded due to over exploitation, bush fires and conversion to agriculture.

In addition to delivering emissions removals to take climate action, this project aims to deliver a number of other benefits including:

  • Providing work and opportunities for economic growth
  • Projects with a gender equality focus
  • Improving sanitation and access to clean water
