In 2015, with the signing of the Paris Agreement on climate change and the establishment of the Sustainable Development Goals (SDGs), the international community recognized that a transformation in the way we use natural resources is a precondition for achieving prosperous, secure and resilient societies. Resource-intensive growth has come at huge environmental cost. Delivering the infrastructure and services needed to support growing economies and populations – above all in developing countries – while addressing climate change and maintaining ecosystem stability will require a revolution in models of resource use.
Excitement is growing around the potential for more ‘circular’ – and sustainable – models of development to deliver this revolution and to unlock economic, social and environmental benefits. Visions for what is known as the ‘circular economy’ (CE) rest on a systemic approach to resource efficiency in which ‘end-of-life’ products and materials – that is, those at the end of their original service lifespan – are not discarded but are instead recycled, repaired or reused through circular value chains. The CE also implies changes to business models, with an emphasis on shared use and rental in preference to independent or single use; as well as changes to consumer preferences, with buyers valuing ‘second-life’ products (i.e. those recycled or adapted for new uses) and asset sharing over individual ownership.
More often than not, even in rich countries, discussion of sustainability has tended to emphasize reform of specific supply chains rather than full-economy transformation. Over the past decade, advocacy of the CE has come primarily from high-profile transnational corporations in consumer industries, such as Philips and Unilever, and from waste management groups such as Veolia. In part due to the CE’s focus on new business models for supply chain management, as well as on industrial regeneration and jobs, the focus of attention around the CE has been on developed countries (above all in the European Union) and China, where CE strategies are most advanced. Less well explored is the role that developing countries other than China can play in a global CE, and the importance of fostering international collaboration and the development of global governance frameworks to support circular value chains at scale.
1.1 The circular economy: a new development paradigm?
Against this backdrop, international organizations including the United Nations (UN), the Organisation for Economic Co-operation and Development (OECD) and the World Economic Forum (WEF) have increasingly called for a new development paradigm: one that prioritizes pathways for poverty reduction and improved standards of living, while promoting resource efficiency and easing pressure on natural resources and the environment. Two milestone agreements in 2015 – the creation of the SDGs and the signing of the Paris Agreement – heralded a radical shift in thinking on growth and development. They placed sustainable production and consumption at the forefront of global efforts to achieve equitable economic growth and tackle climate change.
Investments in emerging and developing economies in the next few years will be critical to delivering on these two global agreements and to shaping natural resource demand, pollution control and waste management pathways for the coming decades. To meet the SDGs, a scaling up of critical infrastructure will be required in low- and middle-income countries to provide economic opportunity and access to modern services. Yet industries essential to this process – cement, steel, energy, for example – demand significant quantities of water, land and minerals. To meet the provisions of the Paris Agreement, infrastructure expansion will need to be founded on low-carbon technology and circular systems that are climate-friendly and climate-resilient.
In recognition of the limits to current resource-intensive models of development, policymakers are paying increasing attention to the CE concept as an alternative development paradigm that can deliver on the SDGs and Paris Agreement. In principle, the shift to a CE would allow countries to reap the benefits of industrialization, increase well-being and reduce vulnerability to resource price and environmental shocks, without depleting stocks of finite natural resources and contributing to environmental degradation (see Box 1).
Much of the interest in the CE centres on its potential to deliver simultaneously on four major political priorities: job creation, balance-of-payments support, supply chain resilience, and climate change mitigation and adaptation. Estimates of the scale of opportunity largely address developed-country settings but have significant bearing for developing countries:
- Job creation. Through capturing the value of materials previously lost to the economy and generating jobs to harness and capitalize on this value, the CE is expected by many to drive job creation and economic growth. Most macroeconomic models find that such a shift will have a positive economic effect, and that many CE activities will offer opportunities for employment at a range of skill levels and across different geographies. A Waste and Resources Action Programme (WRAP) study in 2015 suggested that shifting to a CE could create up to 3 million extra jobs in Europe by 2030. In developing countries where large numbers of young people are entering the labour market each year, ensuring adequate employment opportunities will be key to fostering economic growth and political stability.
- Balance-of-payments support. As imports increase to meet rising demand for goods from growing populations, developing-country governments will need to identify opportunities to avoid balance-of-payments deficits. A series of studies estimates the potential scale of savings from shifting to a CE to be in the multi-billions and trillions of dollars in developed countries. A McKinsey analysis for the Ellen MacArthur Foundation (EMF) projected savings in materials costs of up to $630 billion per year by 2025 in EU manufacturing sectors. Similar benefits potentially apply to developing countries. An Arup study, also for EMF, estimated that a transition to the CE at scale in China could save businesses and households RMB 70 trillion ($10.4 trillion) by 2040, equivalent to 16 per cent of China’s projected real GDP. Accenture identified a $4.5 trillion opportunity by 2030. In India alone, EMF estimates that the CE could create opportunities worth $218 billion per year by 2030. Harnessing new opportunities for value creation will be critical to supporting continued industrial growth in developing countries, particularly in those that currently depend heavily on natural resource rents.
- Supply chain resilience. Fears of resources ‘running out’ have subsided in line with recent resource price falls, but price volatility continues to provide an important incentive – for resource-importing and -exporting countries alike – to pursue less resource-intensive economic pathways. In recent years, moreover, there have been growing concerns over reliance on critical material inputs for advanced technologies – for example, rare earth elements for smartphones or cobalt for electric vehicles. These resources are concentrated in a handful of producer countries, many of which do not have adequate resource governance frameworks to mitigate the environmental and social risks from mineral extraction. Circular value chains and models of product sharing and reuse are expected to reduce countries’ exposure to resource supply risks, but will at the same time bring structural changes to resource-intensive developing economies. As demand for raw materials lessens in line with the transition to a CE, potentially significant structural changes will be required to ensure these countries’ continued participation in high-value international supply chains.
- Climate change mitigation and adaptation. A recent report by Material Economics, a Swedish consultancy, suggests that shifting towards a CE could reduce EU emissions from heavy industry by as much as 56 per cent by 2050 relative to a baseline scenario. According to the International Resource Panel (IRP), more resource-efficient practices could be critical to achieving the commitments in the Paris Agreement. The IRP projects that resource efficiency approaches could reduce greenhouse gas emissions by 60 per cent by 2050. Savings on individual resources can be even higher: producing aluminium from scrap results in a 90–95 per cent reduction in energy inputs and greenhouse gas emissions. CE practices can also contribute to climate adaptation and resilience, including more efficient use of water and energy resources, improved management of land ecosystems to mitigate climate-induced yield losses, and innovative approaches to disaster-ready building and infrastructure construction. With middle- and lower-income countries expected to experience the worst effects of climate change in the short to medium term, exploiting the synergies between the CE and climate mitigation and adaptation will be key to delivering on global commitments under the Paris Agreement while lowering the costs of building climate-resilient infrastructure and industry.
