Law 1083/2006 establishing rules on sustainable urban planning

This document mandates local authorities to formulate and adopt mobility plans that prioritise alternative modes of transport, namely walking, cycling, public transport using clean fuels, and other means of alternative mobility. It also charges the relevant ministry to edict levels of prevention, alert or emergency, including the exposure times through which it will be considered that there is a serious threat to health, as well as the procedures that environmental authorities must follow to declare any of the states of environmental emergency.

This law is further detailed in application decree 798/2010.
