The U.K. plans to ban plastic straws, stirrers and plastic-stemmed cotton swabs, Prime Minister Theresa May announced Wednesday at a meeting of Commonwealth nations.
"Plastic waste is one of the greatest environmental challenges facing the world," May said in a statement, in which she called the U.K. government "a world leader on this issue."
Downing Street said an end to sales of the single-use products is expected after the government launches a "consultation" later this year. May's statement also said the government "will work with industry to develop alternatives and ensure there is sufficient time to adapt. It will also propose excluding plastic straws for medical reasons."
The proposed ban is an effort to reduce the plastic polluting the earth's waters: 150 million tons, according to the announcement, killing one million birds and over 100,000 sea mammals, which either eat the waste or get tangled in it.
BBC science editor David Shukman noted a few reasons to be skeptical of May's announcement, including that bolder steps being taken elsewhere:
"When ministers talk of the UK leading the world on this hot topic it's worth casting an eye over the actions of other countries. Dozens have actually banned plastic bags — Britain has a system of retailers having to charge for them.
"And since last year Kenya has adopted the most draconian measures of all: there are fines if you use a plastic bag and if business people are caught making or importing them, they actually face up to four years in jail."
The move follows recent efforts by U.K. environment secretary Michael Gove to limit plastic waste in oceans, the Financial Times reports:
"In recent months, Mr Gove has announced plans to force thousands of small retailers in England to charge 5p for plastic bags and introduced a ban on the microbeads used in facial scrubs and toothpaste.
"He has also announced a consultation on the introduction of a deposit system for plastic bottles and cans, but he faced criticism on Wednesday over a 'lack of urgency' in efforts to introduce such a scheme.
"Speaking to the Commons environmental audit committee on Wednesday, Mr Gove said he hoped the deposit scheme would become law by 2020.
"Mary Creagh, the committee's chairwoman, responded: 'It is disappointing that having announced the deposit return scheme last year, the government will not be bringing in this vital part of tackling plastic waste until 2020 at the earliest.' "
In February, Gove tussled with European Commission Vice-President Frans Timmermans on Twitter over whether it was the U.K. or EU that was moving faster in banning single-use plastics.
Music festivals in the U.K. aren't waiting for legislation, though. Organizers at the 60-some member Association of Independent Festivals committed to banning plastic straws at their events this season, and pledged to eliminate all single-use plastic at their events by 2021.
In the U.S., a number of major cities have enacted plastic bag bans or fees; such measures are often highly contentious. And starting June 1, the city of Malibu, Calif., will ban restaurants and food vendors from offering or selling plastic straws, stirrers or utensils.
