The 30th UN Climate Change Conference, COP30, is currently happening in Belém, Brazil, from November 10 to 21. This summit gathers leaders, scientists, and industry experts to evaluate global efforts to tackle climate change. This year, there’s a real push for countries to submit updated plans to cut greenhouse gas emissions. So far, only about a third have done this, although the UK has set a more ambitious goal.
COP30 is focused on tracking progress from the 2015 Paris Agreement, which aims to limit global temperature rise to 1.5°C above pre-industrial levels. Delegates are discussing important topics, like transitioning away from fossil fuels and finding ways to raise $1.3 trillion in climate finance for developing countries. Brazil has also introduced a $125 billion initiative called the Tropical Forests Forever Facility to protect crucial forest ecosystems.
A new highlight at this year’s conference is Circular Economy Day, which took place on November 11. This marks a significant step as it emphasizes the importance of circular practices—such as reducing waste and maximizing resource use—in fighting climate change.
“Climate change talks can seem distant and complicated, but they are vital for resource and waste managers,” said Dan Cooke, Director of Policy at CIWM.
Experts note that while switching to renewable energy can cut up to 55% of global emissions, the remaining 45% comes from how materials are made, consumed, and discarded. This gap highlights the need for sweeping changes across supply chains and waste management. Solutions discussed included preventing waste, promoting repair and reuse, and improving recycling efforts.
Cooke pointed out that the UK’s progress has been promising. There has been a significant decline in emissions as the country shifts from landfill use to higher recycling rates. Currently, the resource and waste sector accounts for approximately 8% of the UK’s greenhouse gas emissions. A new roadmap aimed at achieving net zero is being developed and will outline further necessary steps.
“Our industry is crucial for building a circular economy,” Cooke added. “It’s uplifting to see the UK recognizing the economic, social, and environmental impacts of leading in climate action.”
The introduction of Circular Economy Day at COP30 may represent a major shift in how climate negotiations occur, recognizing the importance of resource management alongside energy systems. With the world facing increasing demand for raw materials and growing waste, integrating circular economy principles into COP discussions could lead to bolder commitments moving forward.
The takeaway from Belém is straightforward: reducing emissions requires a complete rethinking of how we design, use, and manage the materials that shape our lives. Change is not just necessary; it is now urgent.
