- Charging coffee drinkers for their disposable cups could cut their use by up to 300 million a year in the UK, according to new research.
- Academics at Cardiff University tested a series of measures to tackle coffee cup waste and encourage the use of reusable cups.
- Prof Poortinga found that the provision of free reusable alternatives combined with environmental messaging and a charge on disposable cups increased the use of reusable cups in one cafe from 5.1% to 17.4%.
- “Our results show that, on average, the use of reusable coffee cups could be increased by up to 12.5% with a combination of measures,” Prof Poortinga said.
- The most notable finding was that, while a charge on disposable cups increased the use of reusable coffee cups, a discount on reusable coffee cups had no impact on their usage.
Charges and other measures could drastically cut the 2.5bn disposable coffee cups used, study finds.
