The report examines how G20 nations, which generate approximately two-thirds of global plastic waste, can utilize extended producer responsibility (EPR) to combat marine plastic pollution. Through a scoping review of 100 sources, it identifies a disparity in effectiveness between mandatory and voluntary EPR schemes, noting that mandatory systems generally achieve higher recycling collection rates. The document provides a detailed mapping of EPR regulations across G20 members and proposes a multi-level approach combining legislative strengthening, market incentives for recycled plastics, technological innovation in ecodesign, and the formal integration of informal waste workers to prevent plastic leakage into the oceans.

The report analyzes seven categories of enclosure-based and open measurement methods for greenhouse gas emissions in sanitation systems. It finds that while enclosure-based methods like flux chambers are widely used, they are limited by scale. Emerging optical and remote sensing methods offer broader coverage but are constrained by high costs. The document highlights a critical lack of empirical data for non-sewered sanitation in low- and middle-income countries and advocates for standardized, affordable methodologies and increased collaboration to improve national greenhouse gas inventories.

The document examines international development finance for nature-based solutions (NbS) in developing countries, particularly least developed countries (LDCs) and small island developing states (SIDS). It highlights the difficulty of accurately quantifying NbS funding and suggests that current estimates may mask a significant finance gap if projects are not explicitly designed to deliver both biodiversity and human benefits.

The report examines the intersection of air pollution and labor markets in East and Southeast Asia, highlighting a significant gap in research and policy regarding informal workers. It finds that while formal sectors are regulated, informal workers—including street vendors and agricultural laborers—face high exposure with minimal social protection. Health burdens are highest in China and Mongolia for ambient pollution, and in Cambodia, Lao PDR, and Myanmar for household pollution. The report argues that current solutions are overly technocentric and fail to address the social inequalities and structural vulnerabilities that determine exposure levels.

The document outlines the wide-ranging health risks associated with traffic-related air pollution (TRAP), noting that in Canada, one-third of the population lives within 250m of a major road. It highlights that children, racialized people, and those in poverty are disproportionately vulnerable to these pollutants. The report links TRAP to respiratory, cardiovascular, neurological, and pregnancy-related illnesses, as well as increased COVID-19 risks, and recommends policy interventions such as low emission zones, electric vehicles, and expanded urban green spaces.

The report synthesizes evidence on the wide-ranging health risks of traffic-related air pollution (TRAP), noting that one-third of Canadians live within 250m of a major road. It details impacts across respiratory, cardiovascular, neurological, and reproductive systems, while highlighting that racialized and low-income populations bear a disproportionate burden. The document also analyzes how the COVID-19 pandemic both exacerbated health risks and demonstrated the potential for air quality improvement through traffic restrictions. It concludes with recommendations for pollution control policies, active transport infrastructure, and urban greening.

The research finds that social impacts are rarely considered in studies of circular cities, and when they are, the focus is limited primarily to governance and employment, particularly regarding informal sector workers. The authors argue that the lack of a coherent overview of social consequences hinders effective policy decision-making and that further research is required to understand effects on health, culture, and human aspirations.

The Ceres2030 project identifies a funding gap of USD 33 billion per year to achieve SDG 2 targets, with USD 14 billion coming from donors and USD 19 billion from recipient countries. The report emphasizes that most existing agricultural research ignores the needs of smallholders, who represent over 80% of the world's farms. Key recommendations include investing in extension services, climate-resilient crops, social protection, and supporting small and medium enterprises (SMEs) in the value chain. The project utilizes a complex general equilibrium model and machine-learning-assisted evidence synthesis to identify a portfolio of 14 policy instruments across three categories: empowering the excluded, on-farm interventions, and food on the move.

The scoping review identifies a critical shortage of robust quantitative evidence regarding refugee education interventions. Out of 1,873 screened articles, only eight met the strict methodological criteria for impact evaluation. Findings suggest that while cash transfers can increase the time children spend in school, they do not necessarily increase overall enrolment. Promising results for learning quality were found in early childhood development programmes, online game-based solutions, and language-enhanced physical education for second-language acquisition, as well as child and youth learning centres for literacy and numeracy in camp settings. The authors highlight significant gaps in research concerning the Global South, long-term impacts, and gender-specific needs for girls.
