The UN global plastic treaty second round negotiations next week are another opportunity for the UK to push for positive changes to our environment as a global leader. At COP26, we secured the Glasgow climate pact, and at COP15 in Montreal, we pushed for global protections of biodiversity and nature. We need to add our voice to negotiations to secure limits to virgin plastic production and unnecessary plastic use. With the fifth largest marine estate in the world, and a population dedicated to protecting our environment and wildlife, we are well placed not only to cut down on our own plastic waste but to lead global efforts in cleaning up our oceans.

Scotland’s deposit return scheme works on the basis of the polluter pays, a principle that incentivises recycling, reduces litter and tackles climate change by reducing the amount of plastic going to landfill or ending up in our oceans. The scheme has been delayed because the First Minister is very keen to work with business to get this right. It is in all our interests, even if it is sometimes tempting to make cheap political points about this issue. The reality is that it is a fine and noble principle, and we should all work to make sure that it can do what it says on the tin. We all need to think about how we use, reuse and dispose of our plastic, because that is the problem that oceans face today.

The plastic has four main negative effects. First, it harms marine ecosystems irrevocably. Nearly 700 marine species are negatively affected by plastic in the oceans, including 100 listed by the International Union for Conservation of Nature as endangered, such as the Hawaiian monk seal, the hawksbill sea turtle and the Galapagos petrel. Moreover, the plastic brings horrifically invasive species into the ecosystem. Secondly, as it breaks down into microplastics, it is eaten by fish and potentially ends up in our food systems, with the health implications that everybody has mentioned—I do not think this is in doubt; it is actually happening now—for humans and particularly for children and babies, given how they are fed. Thirdly, the plastic has economic implications, impacting shipping through propellor entanglement and other marine activities, especially fishing, and undermining tourist areas. Fourthly and importantly, there is a growing body of research showing that by reducing oxygen in the water and thereby the amount of life that oceans can sustain, the plastic almost certainly reduces the ability of oceans to store carbon and therefore combat climate change.

If we continue on the current trajectory, the OECD estimates that global plastic production will double by 2040. In the UK alone, it is estimated that 5 million tonnes of plastic is used every year, nearly half of which is packaging. We cannot detach plastic from climate change. Plastic is highly carbon-intensive to produce. According to a study published in the journal, Nature , last year, plastics are responsible for 4.5% of global greenhouse gas emissions, contributing about 1.8 billion tonnes of carbon emissions annually. Tackling plastic production means saving the planet.
