Global Plastics Treaty

Alex Sobel Excerpts

Thursday 17th July 2025 Commons Chamber

[Dr Arthur]

I agree with my hon. Friend. I know that it is important to his constituency, because I can remember how people were really concerned about plastic cotton buds getting washed up on Portobello beach. Thankfully, through changes, that is now much rarer, but it is still an issue.

In Scotland alone it is estimated that we generate around 300,000 tonnes of plastic packaging items annually and, as of 2021, we were recycling only about 4,500 tonnes of that. Each month, Scotland exports about 100 tonnes of waste to different parts of the UK and right across the world. That is an export that I am not proud of. Poor planning on the part of the Scottish Government means that, by the start of next year, 100 tonnes of waste a day will be moving from Scotland to England to be processed.

That is clearly not sustainable, but it seems that we have become all too comfortable recycling being a matter of “out of sight, out of mind.” We have to remember that once we lose sight of our waste, in many cases we also lose control of what is happening to it. Many residents write to me about that.

Even if we were to develop the processing capacity at home, dealing with plastics will always be a problem so long as our consumption remains high, so a much stronger focus needs to be placed on reuse and developing a circular economy, as we heard earlier, not just in Scotland but throughout the UK. In my constituency, I am proud to say that I have several organisations that promote reuse, ranging from sharing libraries to repair and reuse charities. I recently spent an afternoon touring one such venture called The Forge, a pop-up community maker space, based in renovated shipping containers on a site in Fountainbridge, next to the canal and just along from my office. It provides tools, facilities and training to people from all walks of life, including students, artists, do-it-yourself enthusiasts and homeless people. When I visited, there was a young man making a hat block. I thought it was for him to store his hat on, but he intended to make a pirate hat for a pirate festival, of all things. I tried to google where the pirate festival was, but it turns out that pirate festivals are quite common, so it could have been almost anywhere.

Arrr!

[Dr Arthur]

Thank you.

As well as the hat block, I also saw tables, chests of drawers and even kitchen utensils being made. We could drastically cut our overreliance on plastics if we had more such initiatives; they empower us to create our own long-lasting alternatives, reusing materials and developing lifelong skills in the process. Another charity in Edinburgh South West—one that is under a little bit of pressure just now—is Four Square’s Edinburgh Furniture Initiative. It largely sells used furniture and household items, and it uses its income—a non-trivial amount of money—to help solve Edinburgh’s housing crisis. It is an absolutely fantastic project.

As I noted, the plastic consumption and processing economies operate across borders, making this an issue that requires a truly joined-up approach. That is why I fully support a deposit return scheme that covers the entirety of the UK; I look forward to its introduction in 2027. That may not be quick enough for some people, and I respect that, but we have to balance the pressing need for change with the economic reality for small businesses, which will have to adapt to the new regulations. As others have said, if hon. Members want to see how not to do this, they should just look to the Scottish Government. Its scheme was an absolute embarrassment. Proper consultation is important, and I think Scotland has shown that.

On a global level, I am proud that the Government have fully recognised the importance of tackling plastic pollution through internationally binding treaties. At the UN talks held in South Korea last year, we supported a draft text on legally binding global reductions in plastic production, and on phasing out certain harmful chemicals and single-use plastics. Unfortunately, a consensus could not be reached, largely due to the usual suspects—China and Russia among them—all pushing back against those targets. The negotiations will remain highly contentious as long as those countries, whose economies are heavily reliant on plastic, want to hang on to it.

Having read Dr Lindner’s evidence to the Environment, Food and Rural Affairs Committee earlier this week, I think an inclusive two-tier model could go some way towards resolving those disagreements, if we cannot get those countries to be as bold and ambitious as I hope the UK is. Some may see that as a compromise that lets major polluters off the hook, but I believe that international co-operation is vital, and similar models have worked well in getting those nations signed up to some kind of baseline target. It would help break the deadlock, and allow high-ambition states like, I hope, the UK to set and hit bolder targets, leading by example. Something is better than nothing. We must make progress on this issue, and a global treaty is essential if we want to protect our planet and the health of future generations.

[Alex Sobel (Leeds Central and Headingley) (Lab/Co-op)]

I am delighted to see that my hon. Friend the Minister, with whom I served in the shadow Department for Environment, Food and Rural Affairs team for three years, will respond to the debate; I look forward to that.

With less than one month to go until the next round of the UN plastic treaty talks in Geneva, we must ensure that the international and domestic focus keeps us on track. We must also ensure that the UK delegation’s priorities are clear, so I thank everybody for taking part in today’s debate. Keeping on track is difficult when the number of fossil fuel lobbyists present at the talks rises in each and every round. Those lobbyists seek to derail the talks, and to prevent any limits to plastic production being agreed. We have seen this before with the tobacco industry. We cannot allow private interests that are damaging to health to take precedence, and we cannot allow the mismanagement of plastics, plastic leakage into the environment and the associated colossal greenhouse gas emissions.

Towards the end of my time on the Environmental Audit Committee, we undertook an inquiry on plastic waste. This was in 2021-22. In the three years since it was published, little has changed. Recycling plastic is difficult. Globally, only 9% of plastic has ever been recycled. Furthermore, the carbon emissions associated with plastics outstrip those from the entire global aviation and shipping industries. Approximately 50% of the plastic packaging waste generated in the UK is exported for recycling—or so we think. That is what we call the UK’s plastic recycling capacity gap. The UK has one of the highest per capita plastic waste levels in the world. Cheap single-use packaging is incentivised over unpackaged products, or investment into reuse and recycling and wider circular economy initiatives, which the Government are seeking to champion. On the EAC, we found that much exported waste was just being dumped, with no prospect of recycling. People diligently recycling at home in the UK would be rightly appalled if they saw what was happening to the plastic they put in their bins —green bins in Leeds—for recycling.

To support our UK delegation and address this issue head-on, the UK should take a lead on the international stage in securing global, legally binding targets to cut plastic production. Our recycling and waste treatment industry is hugely supportive of the proposed treaty set out at the discussions, and supports a binding target to reduce global virgin plastic production. The Government need to support the policy measures necessary to make that workable in practice. If the Government develop a clear road map for implementing the policies required to deliver a domestic circular economy for plastics, they could set a binding, viable target for reducing virgin plastic production. They could also set out clear policy interventions to stimulate end-market demand for recycled plastics, and create the conditions for major new investment in plastics sorting and reprocessing infrastructure, so that we end the plastics recycling capacity gap in the UK, create jobs in plastics reprocessing, ensure quality, and ensure that plastic is being recycled, not just dumped. That would be a Great British plastic initiative.

The UK exports approximately 50% of its plastic packaging waste. We must set out proposals for clamping down on illegitimate exports of plastic waste being dumped overseas. While the vast majority of plastic waste exported from the UK is for reprocessing, which is managed in an environmentally sound manner, there have been instances in the past few years where illegitimate exports of low-grade plastics have been dumped or burned overseas. A robust and properly resourced regulator could be empowered to enforce the right standards and clamp down on illegal waste exports. We must end plastic dumping.

The UK Government have already implemented strong steps to improve the quantity and quality of plastics sent for recycling. However, Governments need to address fossil fuels’ influence in politics, particularly in the international plastic treaty negotiations. That is the only way we can deliver a circular economy for plastics. There needs to be sustainable long-term demand for any recycled product created. Otherwise, we will carry on with the unsustainable practice of using virgin plastics, and the fossil fuel industry will continue to have an international influence on our UN processes.
