Britain should charge a 25 pence ($0.34) "latte levy" on disposable coffee cups to cut down waste and ban them if a recycling target is not met by 2023, a committee of lawmakers said on Friday.
Less than 1 percent of coffee cups are recycled in Britain because of the tightly bonded plastic liner, the difficulties of recycling packaging which has been in contact with food and drink and a lack of facilities, the lawmakers said.
Chains Pret A Manger, Costa Coffee, Caffe Nero, and Greggs alongside US firm Starbucks are among the biggest coffee-sellers in Britain and have rapidly expanded in the past 10 years to meet increasing demand.
Although some outlets give a discount to customers using their own cup, only 1 to 2 percent of buyers take up the offer, according to parliament's environmental audit committee which said a "latte levy" was needed instead.
"The UK throws away 2.5 billion disposable coffee cups every year; enough to circle the planet five and a half times," said chair of the committee, Mary Creagh.
"We're calling for action to reduce the number of single use cups, promote reusable cups over disposable cups and to recycle all coffee cups by 2023," she said.
The committee said that money raised by the charge should help improve recycling facilities and if the 2023 target is not met then disposable coffee cups should be banned.
The Irish parliament is considering banning single-use coffee cups while the German city Hamburg said in 2016 it will no longer use coffeemakers with aluminum capsules in its own offices or buildings.
In October 2015, Britain introduced a charge of 5 pence on all single-use plastic bags provided by large shops, which led to an 83 percent reduction in plastic bags used in the first year.
On Friday the environment ministry said the government was working closely with the sector and had made progress in increasing recycling rates.
"We are encouraged by industry action to increase the recycling of paper cups with some major retail chains now offering discounts to customers with reusable cups," said a ministry spokeswoman.
"We will carefully consider the committee’s recommendations and respond shortly," she said.
Caffe Nero said it was working with others to understand and address the issues which prevent the widespread recycling of paper cups.
Costa Coffee and Greggs said they offered a discount to those using reusable cups but Costa said the government also needed to focus on improving recycling infrastructure. Pret A Manger's customers have benefitted from a 50 pence discount from this week.
US chain Starbucks will trial a 5 pence levy at up to 25 London branches in February for three months.
"We will investigate the impact of a 5p charge on a paper cup, coupled with prominent marketing of reusable cups, on customer behavior," it said in a statement posted on its website.
