The 30-second TV advert airs this week and aims to encourage more people to “make the switch to a more sustainable choice”.
PG Tips said shoppers are five times more likely to buy sustainable products and are “demanding a cuppa that not only tastes good but does good for the planet”.
Fiachra Moloney, tea director at brand owner Unilever UK&I, said: “Earlier this year, we completed the transition to biodegradable tea bags and now have the opportunity to shout about it in the hope that it will encourage other brands to do the same.
“With its warm and heart felt message we want this TV campaign to encourage tea lovers to question what their tea bags are made of and if they can make the switch to a more sustainable cuppa.
“In the meantime, we are continuing to work hard to remove our plastic wraps and make our packs fully plant-based.”
