The Circular Economy: Cities Leading The Transition

Marta Suplicy

Marta Suplicy, Municipal Commissioner of International Affairs for the City of São Paulo, asserts that cities—even megacities such as São Paulo—can lead the transition to a circular economy. Drawing from Sao Paulo's impressive initiatives, Suplicy shares the inspiration and the road map for regenerative urban policy, with no one left behind.The circular economy is a key to not only fighting climate change and implementing sustainable development, but as a tool for transforming our reality and the cities we live in. It is an instrument that allows a municipality to harness the potential of food production, food security with a shorter production chain, and lower emissions. It can open new perspectives and opportunities as well as offer ways of building a new economic model. The transition to a fair and responsible circular economy also involves the study, planning, and setting of priorities with the effective participation of civil society.


Latin America is a region with great biological diversity, allowing truly transformative experiences to create regenerative value chains from our abundant resources while promoting and fostering local economies. Over the years, São Paulo has been paying close attention to issues such as regenerative agriculture and waste management to build well-structured urban policy. In recognition of this leadership, we signed a Cooperation Agreement with UN-Habitat. And in early 2020, we were recognized as Strategic Partners with the Ellen MacArthur Foundation, alongside London and New York City.


Connecting The Dots: A Robust Public Policy

In addition to these potentials, São Paulo has already approved and is developing a circular food system across our city. It is promoting new businesses, jobs, training, and education opportunities by creating a system of positive overflows. The Connect the Dots project is one of our biggest success stories in recent years and is now entering a next phase. The initiative was the winner of the Bloomberg Philanthropies' Mayors Challenge Award in 2016 and subsequetly was featured in the BBC's documentary series Transforming Cities. After several successful years and with the end of Bloomberg’s financing, São Paulo is preparing to make Connect the Dots a lasting public policy. Cases like this will serve as inspiration for the development of urban and sustainable food systems.


Another food circularity initiative in São Paulo is our Combatting Food Waste program, which leverages the hands-on knowledge of our public agencies overseeing our food supply logistics. São Paulo's food waste is delivered to the Municipal Food Bank, where it goes through screening before 85% is donated to those facing food insecurity. The 15% unfit to distribute for meals is then delivered to the city's sustainable composting yards. This residual food waste is transformed into high quality organic compost, used throughout our city's parks and distributed for free to our residents.


Rainforest and Plastic 

With over 12 million inhabitants, São Paulo has the potential to significantly reduce climate impacts through circular economy systems that offer a sustainable model for urban public policy. The city is one of the first and remains one of the few regional metropolises to commit to a circular model for plastics and to enact the reduction and elimination of single-use plastics. Our main partners for developing São Paulo's circular economy include the Ellen MacArthur Foundation and the United Nations Environment Programme, with whom we have collaborated since 2019 in The New Plastics Economy. This partnership applies a circular economy model to areas beyond the food initiative, transforming São Paulo into a circular capital.


The circular economy also provides opportunities to foster more sustainable land use, one that cultivates organic food from regenerative agriculture while ensuring income generation for farmers and protecting native rainforest. This path is transforming São Paulo into a green capital and enabling a just and equitable economy. As recognition of that, São Paulo received the title Ibero-American Green City from the Union of Ibero-American Capital Cities (UCCI) this past September.


Communication and Public Engagement

In early May 2022, we hosted the inaugural Circular Economy Week in Latin America, offering a spectrum of circular economy panels with experts from academia, civil society, business, and the public sector. To engender broad public engagement with the UN Sustainable Development Goals (SDGs), São Paulo hosted the first “Virada” SDG Event in July 2022, with 10 event hubs throughout the city. Partnering our municipal school system, Virada brings meaningful education and understanding in the SDGs to our youth living across the farthest reaches of metropolitan São Paulo.


We believe that these types of events and public communication initiatives offer both the inspiration and the dialogue necessary to engaging our city's diverse stakeholders and to furthering effective policies. Yet more than that, education is one of the main pillars of this circular transition. It is only by fostering knowledge around climate change and the importance of sustainable business that we will be able to make the powerful shifts towards a circular economy. This is made possible with the help of schools, theatres, live events, televised talks shows, and even TV soap operas. All these platforms help us to address and engage with the range of topics at hand.


Conclusion

As you can see, São Paulo is harnessing many innovative solutions to address climate change and sustainability through a circular economy approach. From best practices to success cases, these initiatives create a whole series of incentives that drive the development of circular solutions for the city. For cities like São Paulo, there are incredible opportunities for wealth generation through the broad implementation of the circular economy and the ongoing dialogue between municipal leadership and citizens. We have a plan and a commitment with our community, and we are driven to deliver it.


Making the transition to a circular economy can provide a policy response for meeting the multiple crises of both climate change and the Covid-19 pandemic, where cities can be the enablers of the systemic shift that is necessary. We understand the action that is needed. Yet to build lasting change, it is key to have everyone on board and committed to delivering impactful projects and policies for a greener future, with no one left behind.


That is our path. And along it, every citizen’s heart in São Paulo is beginning to embrace the circular economy.

February 20, 2026 As someone who works closely with sustainability practitioners and leaders, I constantly hear the same themes: “How do I get leadership to say yes?” “How do small businesses realistically do this?” “How do we scale change without burning out?” That’s exactly why I’m so excited about our upcoming webinar and working sessions. These aren’t theoretical discussions. They’re practical, interactive, and designed for those of us doing the hard work of driving sustainability forward — often without formal authority, large budgets, or perfect systems. Here’s what’s coming up and why I believe these sessions matter right now! Webinar: The advantages and challenges for small businesses in sustainability March 5, 12:00pm EST We often center sustainability discussions on large corporations. ESG frameworks. Reporting mandates. Multi-billion-dollar net-zero commitments but small businesses make up the majority of our economy. In our upcoming webinar, The Advantages and Challenges for Small Businesses in Sustainability , Colleen Spear brings clarity and practicality to this often overlooked audience. As the founder of Spearpoint Strategies in New England, Colleen works directly with small businesses across industries — from bottle manufacturing to law to clothing design. She helps organizations embed sustainability into operations and strategy through certification support, fractional management, and strategic planning. This session will explore: The barriers small enterprises face in sustainable business spaces Why most sustainability advice overlooks small business realities The natural strengths small businesses possess How to apply sustainability practically within constrained environments Small businesses often lack the complexity — and bureaucracy — of larger corporations. That agility can be a major advantage. Decision-makers are accessible. Values can be integrated quickly. Cultural shifts can happen faster. Rather than positioning small businesses as behind, this session reframes them as powerful drivers of innovative, community-centered solutions. If you work with small enterprises, advise them, or operate one yourself, this webinar will provide actionable insights and language you can apply immediately. Webinar: Influencing Up: Strategies for Sustainability Leaders April 28, 5:00pm EST Our upcoming session with Dr. André Taylor, Strategies for ‘Influencing Up’ as a Sustainability Leaders , focuses on one of the most critical — and underdeveloped — skills in sustainability work: influencing without authority. Dr. Taylor brings a powerful combination of experience. He began his career as an environmental manager and scientist before earning a mid-career PhD in leadership at Monash University. Today, he serves as Leadership Specialist and Adjunct Associate Professor at the International WaterCentre and works extensively with sustainability and executive leaders. Why does this matter? Because sustainability practitioners rarely have direct authority over finance teams, executives, procurement departments, or policymakers. Yet we are expected to influence all of them. This session will explore: How to gain buy-in from senior leaders How to navigate functional silos How to influence across sectoral boundaries How to build authority when you don’t have the title What I appreciate most about this session is that it reframes influence as a skill — not a personality trait. We’ll dive into practical tools and concepts that help sustainability leaders: Speak the language of decision-makers Align initiatives with strategic priorities Understand motivations and incentives Work effectively across power dynamics If you’ve ever felt stuck waiting for approval, resources, or executive sponsorship, this webinar is designed for you. Implementing the AIMS Framework: From Momentum to Scale Four Interactive Working Sessions: March 18th — Amplify (12pm EST) April 22nd — Influence (12pm EST) May 12th — Multiply (12pm EST) June 25th — Scale (12pm EST) For those ready to go deeper, we’re offering a four-part interactive working series led by Dr. Jacqueline Kerr. Dr. Kerr has been published in Harvard Business Review and is in the top 1% of cited social scientists worldwide. Her work blends behavior change, implementation science, and systems thinking to help sustainability leaders deliver results — even in resource-constrained settings. These sessions aren’t passive webinars. They’re Miro-based, hands-on working sessions built around real initiatives participants are leading. Here’s how the journey unfolds: AMPLIFY — Recognizing Hidden Success We begin by mapping sustainability wins — even small ones — and identifying their ripple effects. Participants will: Surface hidden ROI Identify informal impact makers Recognize patterns across companies Publicly commit to amplifying a success story Key insight: change is already happening — it’s just often invisible. INFLUENCE — Removing Barriers Without Authority We diagnose stalled initiatives using an Action Audit framework. Together, we map barriers across: Strategy & Design People & Engagement Systems & Structures Feedback & Adaptation Participants will leave with: Clear barrier diagnoses Peer-tested influence strategies Commitment to remove one key blocker The big realization here? Most stalled initiatives are people challenges embedded within unsupportive systems. MULTIPLY — Creating Action Hubs We explore what makes groups succeed versus stall and design collaborative “action hubs” around shared problems. Participants will: Identify high-impact problems worth solving together Map who needs to be involved Develop invitation language Learn facilitation tactics that build ownership When groups co-design solutions, momentum becomes self-sustaining. SCALE — Building Systems That Spread Change Finally, we design pathways for scaling impact beyond individual teams. We’ll: Map where wins can spread Identify facilitator pipelines Explore how peer networks enable growth Commit to developing new leaders The insight here is transformative: when you train facilitators and activate system levers, change no longer depends on one sustainability champion pushing relentlessly. Why These Sessions Matter Now Across sectors, sustainability professionals are navigating political tension, budget constraints, competing priorities, and burnout. What excites me about this lineup of upcoming webinars and working sessions is that they address the real work: Influence without authority Practical sustainability in small enterprises Behavior change and implementation Scaling change through systems, not heroics These experiences are designed not just to inform — but to equip. Whether you're looking to sharpen your executive influence, support small business transformation, or move from isolated wins to systemic impact, there’s a session built for you. And perhaps most importantly, these sessions create community. You won’t just learn frameworks — you’ll see patterns across organizations, borrow strategies from peers, and build networks that last beyond a single meeting. If you’re serious about driving sustainable change in 2026, I invite you to join us. We’re not just talking about sustainability. We’re building the leadership capacity to deliver it.

January 16, 2026 At the International Society of Sustainability Professionals (ISSP), strategy is not theoretical. It is practical, action-oriented, and grounded in the real needs of sustainability professionals working in complex and rapidly evolving environments. The ISSP 2026 Strategic Plan is a one-year, execution-focused roadmap designed to strengthen ISSP’s role as a global professional association for sustainability practitioners. Built directly from member feedback gathered through Town Halls, surveys, and ongoing conversations, the plan focuses on three strategic priorities: financial stability, relevant professional knowledge, and meaningful member engagement. This article explains what the 2026 Strategic Plan is, why these priorities matter, and how member input directly shaped ISSP’s direction. What the ISSP 2026 Strategic Plan Is—and Is Not The 2026 Strategic Plan is not a long-term vision statement or a five-year forecast. It is a focused, one-year plan designed to deliver measurable progress. The plan is intended to: Strengthen ISSP’s financial sustainability Modernize sustainability education and credential resources Improve the member experience across career stages Each priority includes defined actions, timelines, and success metrics, ensuring accountability and transparency.

Elizabeth Dinschel, MA, MBA, is the Executive Director of ISSP Earlier this month, we hosted our first global ISSP Town Hall since I stepped into the role of Executive Director. I logged off that call energized, humbled, and deeply grateful for the honesty, generosity, and care that our members brought into the space. This Town Hall was never meant to be a one-way update. It was designed as a listening session — a chance for ISSP leadership and staff to hear directly from sustainability professionals across regions, sectors, and career stages. And you delivered. What follows are a few reflections on what I heard, what we learned, and where we’re headed next together. Why We Called This Town Hall ISSP has gone through a period of transition — new leadership, new staff, and a renewed focus on modernizing how we serve a truly global membership. Change can be energizing, but it can also create moments of uncertainty and disconnection. We knew we needed to pause, gather our community, and listen with intention. The Town Hall brought together members from multiple continents, industries, and disciplines. Sustainability practitioners, consultants, engineers, communicators, policy professionals, and career-transitioners all showed up with thoughtful questions and candid feedback. One thing was immediately clear: this community cares deeply about its work, about each other, and about ISSP’s role in supporting sustainability professionals at a challenging moment for the field.
