The National Trust has ditched plastic for the annual membership card it sends out to 5 million members, it has announced. The new card will be made from a type of strong and durable paper featuring a tough water-based coating, with the paper certified by the Forest Stewardship Council. They will be produced in a mill powered by its own biomass. The trust said the new cards would avoid the use of 12.5 tonnes of plastic a year. The new cards will be entirely recyclable and compostable, as well as coming in at a fraction of the cost of the old cards, which were made of plastic and chalk, a byproduct of the mining industry. The National Trust said the move was part of a range of measures it was bringing in to protect the environment and tackle the climate emergency, after a survey showed it was backed by the majority of its members.
