Forecasting future trajectories of the epidemic is crucial for providing an evidence base for policy change. In this study, we examine the historical trends of the global, regional, and national prevalence of adult overweight and obesity from 1990 to 2021 and forecast the future trajectories to 2050. Methods Leveraging established methodology from the Global Burden of Diseases, Injuries, and Risk Factors Study, we estimated the prevalence of overweight and obesity among individuals aged 25 years and older by age and sex for 204 countries and territories from 1990 to 2050. Retrospective and current prevalence trends were derived based on both self-reported and measured anthropometric data extracted from 1350 unique sources, which include survey microdata and reports, as well as published literature. Specific adjustment was applied to correct for self-report bias. Spatiotemporal Gaussian process regression models were used to synthesise data, leveraging both spatial and temporal correlation in epidemiological trends, to optimise the comparability of results across time and geographies. To generate forecast estimates, we used forecasts of the Socio-demographic Index and temporal correlation patterns presented as annualised rate of change to inform future trajectories. We considered a reference scenario assuming the continuation of historical trends. Findings Rates of overweight and obesity increased at the global and regional levels, and in all nations, between 1990 and 2021. In 2021, an estimated 1·00 billion (95% uncertainty interval [UI] 0·989–1·01) adult males and 1·11 billion (1·10–1·12) adult females had overweight and obesity. China had the largest population of adults with overweight and obesity (402 million [397–407] individuals), followed by India (180 million [167–194]) and the USA (172 million [169–174]). The highest age-standardised prevalence of overweight and obesity was observed in countries in Oceania and north Africa and the Middle East, with many of these countries reporting prevalence of more than 80% in adults. Compared with 1990, the global prevalence of obesity had increased by 155·1% (149·8–160·3) in males and 104·9% (95% UI 100·9–108·8) in females. The most rapid rise in obesity prevalence was observed in the north Africa and the Middle East super-region, where age-standardised prevalence rates in males more than tripled and in females more than doubled. Assuming the continuation of historical trends, by 2050, we forecast that the total number of adults living with overweight and obesity will reach 3·80 billion (95% UI 3·39–4·04), over half of the likely global adult population at that time. While China, India, and the USA will continue to constitute a large proportion of the global population with overweight and obesity, the number in the sub-Saharan Africa super-region is forecasted to increase by 254·8% (234·4–269·5). In Nigeria specifically, the number of adults with overweight and obesity is forecasted to rise to 141 million (121–162) by 2050, making it the country with the fourth-largest population with overweight and obesity. Interpretation No country to date has successfully curbed the rising rates of adult overweight and obesity. Without immediate and effective intervention, overweight and obesity will continue to increase globally. Particularly in Asia and Africa, driven by growing populations, the number of individuals with overweight and obesity is forecast to rise substantially. These regions will face a considerable increase in obesity-related disease burden. Merely acknowledging obesity as a global health issue would be negligent on the part of global health and public health practitioners; more aggressive and targeted measures are required to address this crisis, as obesity is one of the foremost avertible risks to health now and in the future and poses an unparalleled threat of premature disease and death at local, national, and global levels.
- IFVI and VBA’s impact accounting methodology: implementation guidePublication . Conde, Sofia; Ferreira, Nuno; Lancastre, FilipaThis research note presents the methodological foundations and practical implementation framework of the Impact Accounting (IA) methodology developed by the International Foundation for Valuing Impacts (IFVI) and the Value Balancing Alliance (VBA). It explains how this approach enables companies to measure, value, and report their impacts on society and the environment in monetary terms, bridging the gap between sustainability disclosure and business decision-making. The note outlines a five-phase development process that ensures scientific rigor, expert validation, and stakeholder legitimacy for each impact topic. It then details a six-step implementation framework that guides companies through context analysis, material impact identification, data collection, outcome assessment, impact valuation, and aggregation into unified impact accounts. Crucially, the methodology is designed for straightforward implementation. When a value factor validated by the Valuation Technical & Practitioner Committee (VTPC) is available, companies simply multiply their existing data points, often those already reported under the CSRD, by the corresponding value factor. This eliminates the need for complex modeling or outcomes definition, making impact accounting both practical and scalable. By combining robust valuation techniques and standardized value factors, the IFVI and VBA methodology provides a clear, comparable, and decision-useful tool for embedding impact accounting in corporate strategies. It enables organizations to move beyond compliance-driven sustainability reporting and toward impact-driven decision-making, creating measurable value for both business and society.
- Implementing impact accounting: opportunities and challengesPublication . Conde, Sofia; Ferreira, Nuno; Lancastre, FilipaThis research note explores the opportunities and challenges involved in the implementation of Impact Accounting (IA). Based on interviews with practitioners and secondary sources, the study finds that while IA remains in an early phase, leading organizations increasingly view it as a strategic tool to inform resource allocation, generate differentiation and leadership, clarify trade-offs, enhance transparency and stakeholder communication, improved data comparability and relevance and complement ESG reporting frameworks, such as the European Sustainability Reporting Standards (ESRS). Nevertheless, IA faces some difficulties, such as its still limited adaptation, mainly due to challenges around data availability, methodological inconsistency, and operational complexity. To overcome these barriers, companies are piloting IA on a small scale, improving internal data systems, and aligning impact valuation with existing ESG data. Participation in standard-setting initiatives, such as the Value Balancing Alliance, is helping address the lack of methodological convergence, while internal use cases, such as scenario analysis and product-level insights, are building confidence and utility. In the absence of regulatory mandates, IA adoption is being driven by leadership ambition and peer influence. As data infrastructure improves and methodologies mature, IA has the potential to move beyond internal experimentation and become a critical tool for aligning financial performance with long-term societal value.

- State of the art of non-financial reporting and impact accountingPublication . Conde, Sofia; Ferreira, Nuno; Lancastre, FilipaNon-financial reporting has become a global norm, with regulatory and societal pressure driving companies to disclose their sustainability performance. Since early 2024, over 250 firms have reported under the EU's Corporate Sustainability Reporting Directive (CSRD), reflecting a broader shift toward mandatory ESG disclosures. Today, 95% of the world's largest companies publish sustainability reports, and over half have a sustainability director. ESG reporting, rooted in CSR efforts since the 1950s and formalized by the UN in 2004, has evolved through global frameworks such as GRI, ISSB, and the EU's ESRS. While these standards promote transparency and long-term value creation, challenges remain, including fragmentation, limited outcome measurement, and greenwashing concerns. A promising development is impact accounting, an emerging approach that monetizes environmental and social externalities to reveal a company's full value creation. It translates non-financial data into financial insights, promising better decisions and strengthening stakeholder trust. The field is advancing rapidly, led by organizations like IFVI, VBA, and IEF, with support from global coalitions and initiatives. Through collaborative efforts such as the Value Accounting Network, actors are building the foundations for consistent, rigorous, and actionable sustainability measurement, marking a critical shift toward impact-integrated business and financial systems.
