This chapter examines the transport sector’s role in climate change mitigation. It appraises the transport system’s interactions beyond the technology of vehicles and fuels to include the full lifecycle analysis of mitigation options, a review of enabling conditions, and metrics that can facilitate advancing transport decarbonisation goals. The chapter assesses developments in the systems of land-...

This report aims to strengthen the evidence base for tackling the health effects of road transport as a key element of the human capital agenda, particularly across emerging and developing economies. It presents the findings of analytical work conducted to assess the health and economic effects of increased road transport motorization. It also provides evidence-based recommendations to inform the ...

This edition of the Global Energy Review is the first comprehensive depiction of the trends that took place in 2024 across the entire energy sector, covering data for all fuels and technologies, all regions and major countries, and energy-related carbon dioxide (CO2) emissions.The latest data show that the world’s appetite for energy rose at a faster-than-average pace in 2024, resulting in higher ...

Euro VI diesel engines contribute significantly to vehicle emission reductions because they have advanced emission control aftertreatment systems for particulate matter (PM) and nitrogen oxides (NOx). These systems are sensitive to the sulfur content in diesel fuel, and for this reason, most major vehicle markets have progressively limited fuel sulfur content to 10 parts per million (ppm), also kn...

The IEA’s Tracking Transport webpage provides detailed and up-to-date information on how the global transport sector is evolving toward clean energy and climate targets. The page includes data on emissions trends, energy use by fuel type, adoption of electric vehicles, and progress on efficiency and policy measures across different regions and transport modes. It also highlights how current develo...

The Working Group III report provides an updated global assessment of climate change mitigation progress and pledges, and examines the sources of global emissions. It explains developments in emission reduction and mitigation efforts, assessing the impact of national climate pledges in relation to long-term emissions goals.The Summary for Policymakers (SPM) provides a high-level summary of the key...

The Global Alliance for Clean Cookstoves offers a FAQ and Stakeholder Guidance document on the new international standard for cookstoves developed by the International Organization for Standardization (ISO) Technical Committee 285 (TC 285) on Clean Cookstoves and Clean Cooking Solutions....

Global trend. In 2023, an estimated 74 (70–77)7 percent of the global population relied primarily on clean cooking fuels and technologies. Although this represents notable progress since 2010, roughly a quarter of the world’s population—around 2.1 (1.9–2.5) billion people—remains dependent on polluting fuels and technologies for cooking.Target for 2030. At current rates, only 78 (74–81) percent of...

Clean cooking access is a defining challenge for Africa’s prosperity. While the number of people without access to clean cooking has halved globally since 2010, the number in sub-Saharan Africa continues to rise. This harms health, economic development, and the environment – contributing to 815 000 premature deaths annually and significant deforestation.In a new report, Universal Access to Clean C...

Recent data indicate a significant reduction in deforestation in some countries. But climate change is making forests more vulnerable to stressors such as wildfire and pests.Projections indicate large increases in wood demand by 2050. Nearly three-quarters of the world’s population uses non-timber forest products.More innovation is needed in the forest sector, driven by escalating forest stressors...
