309g of CO2 per natural cork stopper and 562g of CO2 per sparkling wine stopper.
Amorim reinforces its sustainability credentials in its 150th anniversary year.
Safeguarding the planet’s biodiversity, combating climate change and fostering sustainability are more important than ever.
Amorim’s commitment to sustainability and the circular economy are pillars of its business activity.
Everything begins in the cork oak forest - one of the world’s 36 biodiversity hotspots - but the commitment to ensuring sustainability runs throughout the group’s business units.
A brand-new study, using a cradle-to-gate methodology, has demonstrated how this commitment to sustainability pays vital dividends in Amorim’s core business of providing top quality cork stoppers to the global wine and spirits market.
Amorim’s natural cork stoppers and sparkling wine stoppers have a remarkable negative carbon footprint, and the latter have the highest CO2 retention level in the global stopper industry.
These are some of the conclusions of the study commissioned by Corticeira Amorim and independently conducted by EY consultants in December 2019.
The study measured everything from the forest floor to finished stopper and concluded that cork closures are a major ally in the wine industry’s battle to maximise sustainability.
