Emissions-economy models are widely used for informing low-carbon development policies and targets. These models typically use historical data sets to quantify interrelationships among key variables, which are then used to translate inputs into forward-looking projections. While such models have been extensively applied in developed countries, they are also being increasingly deployed in developing countries. These… Continue reading Addressing path dependence in emissions-economy models for emerging economies: Implications for identifying low-carbon development pathways

We attribute variations in key energy sector indicators across global climate mitigation scenarios to climate ambition, assumptions in background socioeconomic scenarios, differences between models and an unattributed portion that depends on the interaction between these. The scenarios assessed have been generated by Integrated Assessment Models (IAMs) as part of a model intercomparison project exploring the… Continue reading Climate ambition, background scenario or the model? Attribution of the variance of energy-related indicators in global scenarios

Climate stabilisation requires mobilising significant investments in low- and zero-carbon technologies, especially in emerging and developing economies. However, access to stable and affordable finance varies dramatically across countries. Models used to evaluate the energy transition do not differentiate regional financing costs and therefore cannot study risk-sharing mechanisms for renewable electricity generation. Here, we first incorporate… Continue reading Reducing cost of capital to finance the energy transition in developing countries: a multi-model analysis

One third of all greenhouse gas emissions come from the way we produce and consume food, and current diets are insufficient to meet environmental and health goals. Given the ubiquity of smartphone usage, apps delivering effective, engaging nudges could be a scalable and promising solution. However, the complexity of apps makes it difficult for stakeholders… Continue reading The effectiveness of mobile app-based interventions in nudging towards sustainable and healthy diets: a systematic review and meta-analysis

Background: The health care industry is the fifth-largest contributor worldwide to CO2 emissions. Therefore, health systems need to curb CO2 emissions to become environmentally sustainable. We conducted a scoping review to identify literature on (1) the environmental impacts of de-implementation of low-value health care (LVC) and (2) the environmental sustainability of alternative solutions for health… Continue reading Double Impact: Reducing low-value care – A win-win for patients and the planet: A rapid scoping review

Background Climate change poses serious risks to human health. At the time of writing, 81 nations pledged to sustainable healthcare systems, with the majority from Low- and Middle-Income Countries (LMICs). The healthcare sector accounts for 4.4% of global greenhouse gas (GHG) emissions, primarily from high-income countries. Without robust GHG mitigation, future increases are predicted in… Continue reading A Systematic Review to Identify the Effectiveness of Greenhouse Gas Mitigation Interventions for Healthcare Systems in Low- and Middle-Income Countries

Healthcare services contribute 1% -5% towards global environmental impacts. The Climate Change Act (2008) set targets for the 100% reduction of 1990 carbon emission level in England by 2050.3 Work identifying and delivering interventions to reduce carbon emissions within healthcare supply chains and models of care delivery, is underway. To complement this work, we aimed… Continue reading Evidence mapping – Quantitative synthesis/meta-analysis Systematic review of effectiveness of interventions to reduce carbon-emissions within secondary healthcare: issues with conducting reliable primary research and identifying trustworthy findings

The Lancet Countdown in Europe (LCDE) aims to provide accessible information on the broadscale health impacts of climate change, and the health co-benefits of climate action in Europe by developing indicators to track changes over time across the continent. 41 indicators track climate-health relationships over the period 1950-2022 across five themes (1) impact, exposure, and… Continue reading Unprecedented warming demands unprecedented action: the 2024 Europe Report of the Lancet Countdown on Health and Climate Change

Introduction: Various epidemiological studies have investigated the incidence of Salmonella and Campylobacter infections in response to climate variations. In this study, we have conducted a comprehensive review and analysis of the existing global epidemiological evidence in order to assess the association between temperature exposure and the risk of Salmonella and Campylobacter infections in diverse climatic… Continue reading The impact of ambient temperature on Salmonella and Campylobacter infections in the context of climate change: A Systematic review and meta-analysis

To contribute to Paris Agreement objectives, non-state actors globally are increasingly developing voluntary emission reduction goals. Cities represent an important group with net-zero or similar plans, but significant variation exists in how they intend to meet these targets. A lack of research exists on the role of carbon offsetting (carbon dioxide removal or avoided emissions… Continue reading Offsetting and insetting in city net-zero plans

The 2020s is arguably the most important decade for climate action in human history. By 2030, either the world will keep alive the goals of the Paris Agreement, or put them out of reach. There are unprecedented waves of momentum for change, as there are limits to change with current approaches, which requires critical reflection,… Continue reading The role of municipalities in implementing just transitions

The “Designing inclusive African coastal cities’ resilience” (INACCT Resilience) project is an action-oriented research project focused on two coastal cities: Durban (South Africa), and Beira (Mozambique), both having recently experienced extreme climate-related flooding that caused severe damage, displacement, and loss of life. Through a transdisciplinary approach, the project aims to enhance proactive, inclusive and evidence-informed… Continue reading Designing inclusive African coastal cities’ resilience
