Allegra is on a green mission! By the end of 2023, we plan to use recycled or FSC certified materials for our cartons and leaflets, promoting sustainable forest management. We're also minimizing packaging where possible.

Our 2025 goal? All paper from sustainable sources. Some US Allegra products already use SFI certified cartons, with other regions joining in from Q3 2023.

Look out for the FSC/SFI logo on our packaging, where regulations permit, a testament to our commitment.


At Allegra, we want to play our part in the global movement to create a healthier planet. Our manufacturing site in Chattanooga, Tennessee implements daily actions that have already driven concrete results:

Climate Action

In all our manufacturing sites, we are taking action to decarbonize our operations through energy efficiency programs, sourcing renewable electricity and switching from fossil fuels to biomass, biogas, heat pumps etc. In our Chattanooga site we have already achieved a 78% reduction in CO2 emissions across Scopes 1 and 2, vs our 2019 baseline since June 2023, and 100% of our electricity is now sourced from renewable sources.

Reduce waste and increase circularity

In all our manufacturing sites, we are working to reduce waste and increase circularity. By 2025 we aim to achieve zero waste to landfill and have a material recovery rate of 90%. In our Chattanooga manufacturing site, only 4% waste still goes to landfill.

Protect natural ecosystems

In all our manufacturing sites, we are aiming at preserving our planet's natural resources: As of 2022, all sites have engaged specific programs targeting pharmaceutical residues in the water stream . And we are aiming at reduce our water withdrawals by 20% by 2030 vs 2019. All manufacturing sites located in sensitive natural areas will also developed Biodiversity management plans by 2030.
