The European Environment Agency (EEA) publishes Signals annually, providing a
snapshot of issues of interest to the environmental debate and the wider public. Signals 2013 focuses on Europe’s air. This year’s edition tries to explain the current
state of air quality in Europe, where they come from, how air pollutants form, and how they affect our health and the environment. It also gives an overview of the way we build our knowledge on air, and how we tackle air pollution through a wide range of policies and measures.
