The Portuguese Cork Association (APCOR) has set up a website inviting consumers to “sign the pledge” to choose natural cork over synthetics. The campaign will encourage consumers to press retailers and producers to use cork.
APCOR said almost two-thirds of UK consumers are blind to the environmental impact of different forms of stoppers, despite 96% recycling their wine bottles.
It claims that once informed of the environmental benefits, 58% said they would choose wines with natural cork stoppers.
The campaign aims to tackle what APCOR says are commonly held myths about cork, including that trees are cut down in the course of production.
Some 22% of Britons admitted to believing this was true and 47% had no idea that trees were not harmed during the process.
