Associate environment minister, Eugenie Sage, yesterday signed the United Nations’ CleanSeas campaign pledge.
New Zealand is the 42nd country to sign after the campaign’s launch in February last year.
The pledge requires signatories to significantly reduce the production and use of non-recyclable and single-use plastic by 2022.
Some scientists estimate that if nothing is done, by 2050 the plastic in the oceans will weigh more than all the fish that live in them.
She wanted businesses to help change people’s behaviour so single-use items, like plastic bags, were not the norm.
