Non-exhaust emissions of particulate matter constitute a little-known but rising share of emissions from road traffic and have significant negative impacts on public health. This report synthesizes the current state of knowledge about the nature, causes, and consequences of non-exhaust particulate emissions. It also projects how particulate matter emissions from non-exhaust sources may evolve in future years and reflects on policy instrument mixes that can address this largely ignored environmental issue.

Non-Exhaust Emissions: An Urban Air Quality Problem for Public Health comprehensively summarizes the most recent research in the field, also giving guidance on research gaps and future needs to evaluate the health impact and possible remediation of non-exhaust particle emissions. With contributions from some of the major experts and stakeholders in air quality, this book comprehensively defines the state-of-the-art of current knowledge, gaps and future needs for a better understanding of particulate matter (PM) emissions, from non-exhaust sources of road traffic to improve public health. PM is a heterogeneous mix of chemical elements and sources, with road traffic being the major source in large cities. A significant part of these emissions come from non-exhaust processes, such as brake, tire, road wear, and road dust resuspension. While motor exhaust emissions have been successfully reduced by means of regulation, non-exhaust emissions are currently uncontrolled and their importance is destined to increase and become the dominant urban source of particle matter by 2020. Nevertheless, current knowledge on the non-exhaust emissions is still limited. This is an essential book to researchers and advanced students from a broad range of disciplines, such as public health, toxicology, atmospheric sciences, environmental sciences, atmospheric chemistry and physics, geochemistry, epidemiology, built environment, road and vehicle engineering, and city planning. In addition, European and local authorities responsible for air quality and those in the industrial sectors related to vehicle and brake manufacturing and technological remediation measures will also find the book valuable. Acts as the first book to explore the health impacts of non-exhaust emissions Authored by experts from several sectors, including academia, industry and policy Gathers the relevant body of literature and information, defining the current knowledge, gaps and future needs

This volume addresses key contemporary aspects in cycling policy, practice and research. Cycling has seen a sharp increase in scientific and policy attention in the past decade. The amount of research has surged over the past couple decades. Also, levels of cycling have increased substantially in many countries and cities, and many areas have seen increases in infrastructure investments. In addition, the last decade has seen innovations in bicycle technology, in particularly the rise of electric-assist (e-bikes) and dock-less bike sharing schemes. This volume reviews the state of the art on cycling from various angles. As such it explores planners’ (engineers’, policy makers’) provisions for cycling, of cyclists’ (and non-cyclists’) travel behaviour, and resulting consequences for individuals and society. One focus is on demand-side aspects, including the use of bicycles and their users including patterns and trends in cycling, determinants of cycling, and modelling of cycling. Another focus is on impacts of cycling, such as emissions, safety aspects, as well as changes during the COVID pandemic. Contemporary overview of key aspects in cycling research and bicycle planning A focus on design for cycling, behavior of cyclists and consequences of cycling

Microplastics are ubiquitous in the natural environment. This report synthesises the current state of knowledge on the sources, fate and risks of microplastics pollution. It then focuses on two sources of microplastics pollution, textile products and vehicle tyres, due to their substantial contribution to global microplastics emissions and currently largely absent policy frameworks to mitigate them.

While plastics are extremely useful materials for modern society, plastics production and waste generation continue to increase with worsening environmental impacts despite international, national and local policy responses, as well as industry commitments. The first of two reports, this Outlook intends to inform and support policy efforts to combat plastic leakage.
