The Drawdown Review 2020 argues that the world can reach Drawdown by the mid-2040s to mid-2060s by scaling existing technologies and practices. The framework categorizes solutions into reducing emission sources, supporting carbon sinks, and improving society. The report emphasizes that the financial benefits of these solutions, with operational savings exceeding implementation costs four to five times over, outweigh the costs of action.

The document argues that while there are signs of a transition to green economies—such as accelerating renewable energy deployment in China and India and the adoption of wellbeing budgets in New Zealand—the 'brown economy' still dominates. It highlights that fossil fuel subsidies (US$ 5.2 trillion) nearly equal the investment needed for Sustainable Development Goals (US$ 5-7 trillion). The report calls for a systemic shift from extraction to restoration and from GDP-centric measures to wellbeing and natural capital accounting, providing specific recommendations for governments, businesses, and civil society to accelerate a just transition.

The 2020 Global Green Economy Barometer evaluates the shift toward sustainable and equitable economic systems. While it notes accelerating energy transitions, a rise in green bonds, and the emergence of wellbeing budgets in countries like New Zealand, it argues that the 'brown economy' still dominates. The report highlights that fossil fuel subsidies reached US$ 5.2 trillion in 2017 and that global energy intensity is declining at only 0.4% per year, far below the 4-10% needed for mid-century decarbonization. It calls for systemic reforms to move beyond GDP, value natural capital, and ensure a just transition for marginalized populations.

The V&A Waterfront in Cape Town has diverted over 11,000 tonnes of waste from landfills over five years, reducing disposal costs by up to 36%. The precinct focuses on organic waste due to its high volume—nearly 70% of landfill waste—and its impact on climate change. Key initiatives include source separation, a waste tariff structure to incentivise tenants, green leases, and the use of an 'eco-intelligence dashboard' for real-time data. The project has resulted in annual GHG emission savings of 4,147 tonnes and the creation of 86 permanent daily jobs. The long-term goal is zero waste to landfill by 2023, with plans for an on-site waste-to-energy plant.

The document examines the GreenPitch Innovation Challenge 2019 as a mechanism to strengthen Cape Town's economic resilience by supporting green Small, Medium and Micro-Sized Enterprises (SMMEs). It argues that multi-stakeholder collaboration and pitching events help fragmented cleantech start-ups overcome resource gaps—such as lack of financial assets and networks—to better address climate-related stresses. The challenge attracted 40 nationwide entries, resulting in five finalists and providing the winner, Nubrix, with R 30,000 in business development support.

The document examines the role of FoodForward SA as a trusted intermediary in South Africa's food supply chain, using a circular economy lens to divert surplus food from landfills to those in need. It highlights the economic and environmental drivers for food rescue in Cape Town, such as high landfill fees and provincial organic waste diversion targets. In 2020/21, FoodForward SA redistributed approximately 7,215 tonnes of food nationally, with specific impacts in Cape Town including the saving of 8,592 tonnes of GHG emissions and the creation of R45 million in retail value from rescued food.

The document examines the potential for recovering construction materials from builders' rubble at Cape Town's drop-off sites to mitigate a regional landfill airspace crisis. It highlights a June 2019 survey showing that contractors at some sites recover an average of 920 bricks weekly, suggesting a business case for low-skilled job creation and support for low-income housing. However, the viability of this model is challenged by labour costs, the need for consistent volumes of quality material, and theft.

A buyback centre in Vrygrond, Cape Town, diverts approximately 1,500 tonnes of waste from landfills annually, providing an annual community income between R950,000 and R1.9 million. The centre employs 20 people and supports 300 waste reclaimers, though it faces challenges regarding land access and infrastructure. The document recommends formalising engagement between the municipality and buyback centres to improve waste management in informal areas.

The document highlights Mushroom Guru (Pty) Ltd as a practical example of urban agriculture in Cape Town, using indoor vertical farming and aeroponics to cultivate medicinal and gourmet mushrooms. It argues that green technology enables intensive, resource-efficient production that reduces water use and utilizes agricultural waste, contributing to a circular economy. The study also emphasizes the role of training and cooperative platforms, like Fungkifriend, in securing market access for small-scale growers and creating economic opportunities within the urban food value chain.

The City of Cape Town (CCT) implemented a circular procurement policy for its wheelie bins, requiring them to be made from 50% HDPE recyclate with a 10-year minimum lifespan. Since November 2014, this initiative has diverted approximately 1,132 to 1,156 tonnes of HDPE from landfills, saving between 1,053 and 1,121m3 of landfill airspace. The programme has generated cost savings of R9 to R10.1 million through lower unit prices and an additional R6.7 million via a bin-exchange scheme where the contractor provides one free bin for every 65kg of condemned material. The project has created 13 permanent and 18 part-time local jobs and reduced Scope 2 CO2 eq emissions by 1,708 tonnes. By sourcing materials locally and securing end-markets for recyclers, the CCT has reduced its vulnerability to global commodity price volatility and supply chain disruptions.

The report outlines opportunities for industrial symbiosis in two Cape Town industrial zones. In Montague Gardens, it highlights the reuse of boiler ash in brick making, the need for treated wood waste solutions, and the potential to shift freight from road to rail. In Atlantis, it identifies opportunities for reusing foundry sand and ash, recovering precious metals from e-waste, and investing in waste-to-energy infrastructure such as pyrolysis and gasification plants. The document argues that establishing a central management body and fostering collaboration on shared services and material exchanges are essential for building business resilience and creating low-carbon zones.

The document details how WISP connected Advanced Technical Sock Industries (ATSI) in the Western Cape with The Care Bear Project in Pietermaritzburg, allowing the latter to use ATSI's yarn fluff waste as stuffing for teddy bears. With free transport provided by The Courier Guy, the initiative diverted 0.18 tonnes of waste annually from landfills and saved The Care Bear Project R10,800 per year, enabling the employment of two additional staff members.

The document details how the Western Cape Industrial Symbiosis Programme (WISP) connected Quality Crate Manufacturers with West Coast Plastics to replace virgin HDPE with recycled pellets. This synergy resulted in the diversion of 35 tonnes of plastic from landfills, the avoidance of 80 tonnes of CO2e emissions, and R350,000 in additional revenue for the recycler.

The document outlines the scale of food loss and waste in South Africa, noting that 27% of produced and imported food was wasted in 2011. It emphasizes a shift in the Western Cape toward mandatory organic waste diversion from landfills by 2027. The brief identifies key drivers for beneficiation, such as the Carbon Tax Act and Sustainable Development Goal 12.3, while detailing barriers including lack of source separation and liability fears regarding food donations. It proposes 29 solutions across prevention, recovery, and recycling categories and advocates for the adoption of the World Resource Institute's FLW Standard for better data recording.

The report identifies significant economic potential in diverting waste from landfills in South Africa, particularly in the Western Cape. Key opportunities are highlighted in the organics, plastics, e-waste, and construction sectors, driven by dwindling landfill airspace, rising disposal costs, and emerging regulations like Extended Producer Responsibility (EPR) and the Carbon Tax Act. The Western Cape is positioned as a greentech hub, with the City of Cape Town generating the majority of the region's waste and offering the highest market value for beneficiation.

The report examines the South African urban water sector, highlighting a projected 17% gap between water supply and demand by 2030. It identifies significant investment opportunities in the agri-processing sector (estimated at R6 billion) and the municipal sector, including wastewater reuse (theoretical potential of R50 billion) and biogas/energy efficiency projects. The document details the regulatory landscape, including the National Water Act and municipal by-laws, and discusses barriers such as low water tariffs, capacity constraints in municipalities, and public perception of reclaimed water.

The report argues that the COVID-19 pandemic acted as an 'X-ray,' exposing deep structural inequalities and the failure of neoliberal policies. It critiques the global fiscal response, noting that while US$ 11 trillion was mobilized, the support was unevenly distributed, favoring high-income countries and corporate interests over the global South and public services. The document proposes an "8 R" agenda for systemic change: re-valuing care, re-empowering public services, re-balancing value chains, reinforcing climate justice, re-distributing economic power, re-regulating global finance, re-inventing multilateral solidarity, and re-defining progress beyond GDP. It specifically highlights the dangers of IMF-mandated austerity in countries like Ecuador and the failure of the Global Health Security Index to predict pandemic outcomes due to its reliance on infrastructure over social determinants of health.

The report advocates for a paradigm shift in sanitation and wastewater management, moving from a focus on waste disposal to one of resource recovery. It details how recovering water, nutrients, and energy from waste streams can improve public health, food security, and climate mitigation while creating economic opportunities. The document provides technical guidance on system design, risk management for human and environmental health, and the institutional and financial frameworks necessary to implement sustainable, context-specific sanitation systems.

The SEI Asia Strategy 2020-24 establishes a framework to bridge science, policy, and practice to achieve environmental sustainability and inclusive development in Asia. The strategy is organized around three primary impact areas: reduced climate risk, sustainable resource use and resilient ecosystems, and improved health and well-being. To achieve these, SEI Asia focuses on five core research and policy clusters: Gender, Environment and Development; Water; Climate Change, Disasters and Development; Urban; and Policy. The document also highlights specialized programs for the Mekong Region and Myanmar, and identifies evolving areas of work including ecological economics, sustainable finance, and the environment-health nexus.

The report finds that while Americans are concerned about the impact of plastics on marine life and water quality, they often feel unable to avoid plastic packaging or believe their individual actions are insignificant. There is strong public support for producer responsibility, with businesses ranked as the most responsible party for reducing plastic waste and the entity that should pay for recycling infrastructure. While there is broad support for positive regulations like credits and refund programs, Americans are more divided on taxes and fees.
