I am very pleased to collaborate with Tearfund to reframe the discussion around waste management in the Plastics Treaty negotiations. The Plastics Treaty is once-in-a-generation opportunity to end Plastic Pollution. We absolutely need to ‘turn off the tap’ by upstream actions to reduce plastic production, but we also need to ‘stop the bath-tub overflowing’ through proper waste management.
This is not a ‘cop out’ for the plastics producers – they are responsible for the high plastics content in municipal solid waste in lower income countries, which cannot afford proper management; so it is their responsibility to ensure that their wastes are collected and recycled properly and to pay all of the associated costs. The scientific part of the Tearfund report shows that extending municipal solid waste collection and controlled recovery and disposal to services to all (95% on SDG indicator 11.6.1) would not only address a major public health and environmental crisis impacting billions worldwide, but also reduce macroplastics dispersal to the environment (and thus available for onward transport to the ocean) by 77% and open burning by 90% . So, let’s make sure that is done!
UPDATE. The report puts forward a fit-for-purpose text on waste management for negotiators. The initial report was issued prior to the negotiation meeting INC-4 in Ottawa from 23-29 April 2024. A second edition was issued in September, to provide specific inputs to the final text negotiations which should have been concluded at INC-5 in Busan 25 November – 1 December 2024.
UPDATE. The modelling for this report by Costas Velis, Ed Cook and Josh Cottam of the University of Leeds used their SPOT model. Their seminal paper showing that uncollected municipal solid waste accounts for 85% of uncontrolled macroplastic dispersal to the environment was published in Nature in September 2024.

As lead author of UNEP and ISWA’s original Global Waste Management Outlook (GWMO) in 2015, and a contributing author to the long-awaited follow-up, I am thrilled to welcome the publication at UNEA-6 this week of GWMO 2024: Beyond an age of waste – Turning rubbish into a resource. Warm congratulations to the lead author, Zoë Lenkiewicz, who has written a concise and engaging report which will hopefully succeed in placing municipal solid waste management firmly where it belongs on the local and international political agenda.
Zoe has summed it up brilliantly in the 300 character summary on the back cover of the easy-to-skim-read 80-page report: ‘The Global Waste Management Outlook 2024 echoes the 2015 Global Waste Management Outlook’s call to action to scale up efforts to prevent waste generation; to extend adequate, safe and affordable municipal solid waste management to everyone worldwide; and to ensure that all unavoidable waste is managed safely.’ My thanks and congratulations to the patient project managers, Daniel Ternald of UNEP and Aditi Ramola of ISWA.

I am pleased that the RICS Land Journal has published online an updated version of my article on the untapped potential for the waste and resource management sector to act as an enabler to unlock significant climate mitigation benefits across the economy. My best estimate of the mitigation potential is at least 15-20% of global carbon dioxide (equivalent) emissions, which is far beyond the IPCC’s estimate of 3% for the narrowly defined end-of-the linear-economy ‘waste’ sector, which is necessarily used in official climate reporting to avoid double counting.
This post supercedes that titled ‘COP26 and the waste and resource sector’, first published on 25 October 2022:
How much can better waste and resource management contribute to mitigating global heating? Prof David C Wilson addressed this question at the Policy Connect Sustainable Resource Forum seminar on October 11 2021. The answer with a high level of confidence is ‘significantly’, perhaps 15-20% of global carbon dioxide (equivalent) emissions. DCW has now written this up as a ‘thought piece’, making the case for prioritising actions at COP26 and beyond to improve waste and resource management and move towards the circular economy. This may be found as both an article and as a video interview on WasteAid’s COP26 online hub; as a feature on CIWM’s Circular Online; and as an ISWA guest blog.

A key constraint to improving waste and resource management in many countries is a lack of access to investment finance. Extending waste collection to all and phasing out uncontrolled dumping and open burning in low-income countries would significantly cut the mass of plastics reaching the ocean. So the UNEP Finance Initiative publication Diving Deep, aimed at banks, insurers and institutional investors, is very welcome. Guidance is provided in the form of a science-based, actionable toolkit, to ensure that their investments, both in product manufacture and in waste management, encourage waste prevention and sound waste management, thus keeping plastics out of the oceans.
The promotional video and the document itself are worth looking at just for the wonderful images by world-renowned photographer Cristina Mittermeier of Sea Legacy. The guidance was prepared by WWF (led by Paula Chin) and RWA (led by Andy Whiteman). DCW played a small role as one of the reviewers.

In his July column, CIWM President David C Wilson makes the case for more investment in resource and waste management as an ‘entry point’ to achieve significant climate mitigation. The sector already has a track record in developed countries, with methane mitigation from landfill since the 1970s, and both methane mitigation and recycling making a major contribution to meeting Kyoto Convention greenhouse gas (GHG) reduction targets between 1990 and 2010. But that early success also means that the IPCC’s 2010 assessment is that the ‘waste’ sector only contributes 3-5% to current GHG emissions. DCW argues that this is a gross underestimate which fails to consider: the current emissions from uncontrolled burning; historical reductions; contributions across the economy from recycling; and waste prevention (particularly food waste). The results suggest that better resource and waste management has the potential for reducing GHG emissions across the World economy by 15, 20 or 25% or even more. Such numbers may be guesstimates, but whatever number we choose to use, the message is still the same. Further investment in this sector, in both developing and developed countries, is a major political priority in order to meet our climate targets.
This article was subsequently re-published by the National Solid Waste Association of India (NSWAI) in their member journal Waste Monitor in July 2019.
