The Second Monitoring Report on Chile's Energy Efficiency Law finds that while the light-duty vehicle industry exceeded the 2025 fuel economy standard of 18.8 km/lge (reaching 19.3 km/lge), this was primarily due to multipliers for plug-in vehicles; the actual sales-weighted economy was lower at 16.9 km/lge. Compliance among importers remained stagnant at 45%. Despite this, the market saw a 200% increase in available BEV models and a 32% decrease in available ICE models between 2023 and 2025. BEV and PHEV prices fell significantly, and the cost per kilometre for BEVs is now 70% lower than for ICE vehicles. These improvements contributed to a reduction of 9.1 million litres of gasoline demand and 21.4 thousand tonnes of CO2 emissions since 2024.

The report describes Nigeria's emerging electric vehicle (EV) ecosystem, highlighting the convergence of private sector innovation, strategic financing, and a pending national policy framework designed to transform the country into an African EV manufacturing hub.

This case study describes the revitalization of Terminal Binjai in Medan, Indonesia, through a community-led design process and 'tactical urbanism'. Led by the Stockholm Environment Institute (SEI) and local partners as part of the UK Partnering for Accelerated Climate Transitions (UK PACT) initiative, the project transformed a neglected transit hub into an inclusive, green mobility node by integrating the needs of marginalized groups and local residents.

This research paper analyzes a survey of 1,020 Swedish residents to identify the primary drivers of transport modal choice and the impact of transport infrastructure on quality of life and the living environment.

This briefing by the Stockholm Environment Institute analyzes the distributional welfare impacts of the 2022 energy price crisis in Sweden. It examines how electricity and fuel price increases affected different income deciles and geographical regions, evaluating the effectiveness of policy responses such as fuel tax reductions and direct compensation. The report highlights that low-to-middle income groups and residents of sparsely populated areas were most affected, and argues that short-term subsidies may conflict with Sweden's long-term climate goals of net-zero emissions by 2045.

This research paper summarizes insights from a series of deep-dive sessions hosted by WRI India in Bengaluru, involving over 20 stakeholders from the commercial electric vehicle (EV) ecosystem, including manufacturers, logistics operators, and financing experts. The document outlines recommendations for accelerating the transition to electric road freight in India to combat emissions driven by urbanization and e-commerce.

This report by the Stockholm Environment Institute (SEI) calculates the consumption-based climate footprint of residents in Umeå municipality based on a 2018 survey. It identifies key emission 'hotspots' and provides recommendations for local policy interventions to align with the goal of reducing emissions to approximately one ton of CO2e per person by 2050.

This report by the Stockholm Environment Institute (SEI) evaluates the implementation of Estonia's Ecological Tax Reform (ÖMR), established in 2005. The analysis finds that while some fiscal goals were met—particularly regarding energy and electricity excise duties—the reform largely failed to reverse negative environmental trends or change consumer and producer behavior by 2018.

This research paper examines how battery cost floors and climate policies influence the global adoption of electric vehicles (EVs) and the resulting impact on passenger road-transport emissions.

The Tees Valley Footprint Report finds that the region's Ecological Footprint (5.12 gha/cap) is over twice the world average, while its Carbon Footprint (10.85 t/cap) is lower than the UK average, partly due to lower disposable income. The report warns that 'Business as Usual' trends will likely increase per capita emissions from housing (5.5%) and transport (8.7%) over 20 years. While food consumption is a significant driver of the Ecological Footprint, the report suggests that targeted housing retrofits and ambitious, systemic transport shifts—rather than small-scale initiatives—are necessary to meet 2050 carbon reduction targets.

This report details the 'From Waste to Traffic Fuel' (W-Fuel) project, which investigated the sustainable production of biogas and its upgrading to biomethane for use as transport fuel in two Estonian counties: Harju and Lääne-Viru. The study compared the environmental and economic impacts of using biogas for combined heat and power (CHP) versus upgrading it to vehicle fuel, while also proposing waste prevention strategies for biowaste and sludge.

Decision 7 of the XVI Forum of Ministers of the Environment of Latin America and the Caribbean establishes a regional network of authorities to address atmospheric pollution between 2008 and 2009, focusing on technical exchanges, capacity development, and the reduction of pollutants, particularly from transport.

This research paper by the World Resources Institute outlines opportunities for countries to strengthen their Nationally Determined Contributions (NDCs) by integrating a broader range of transport solutions based on the "Avoid-Shift-Improve" framework.
