Translation of "seuil olfactif de l'air " (French → English) :

Member States should consult with one another if, following significant pollution originating in another Member State, the level of a pollutant exceeds, or is likely to exceed, the relevant air quality objectives plus the margin of tolerance where applicable or, as the case may be, the alert threshold.

- In order to set objectives for ambient air quality, limit values to be achieved within ten to fifteen years are to be set for each pollutant, together with alert thresholds and margins which may be exceeded temporarily during the period required to introduce measures to improve air quality.

- In order to maintain or improve ambient air quality, there is provision that: . when alert thresholds are exceeded the public must be informed; . when permitted values are exceeded, Member States must take action and prepare plans to improve air quality; . when concentration levels are between permitted values and the long-term limit values, these limit values must be achieved within the time-limits fixed.

In relation to the fifth environment programme, this framework Directive establishes the basic principles of a common strategy to define and set objectives for ambient air quality in order to avoid, prevent or reduce harmful effects on human health and the environment, assess ambient air quality in the Member States, inform the public, notably by means of alert thresholds, and improve air quality where it is unsatisfactory.

Specifically, those basic principles are the following: - define and establish objectives for ambient air quality in the Community designed to avoid, prevent or reduce harmful effects on human health and the environment as a whole; - assess the ambient air quality in Member States on the basis of common methods and criteria; - obtain adequate information on ambient air quality and ensure that it is made available to the public, inter alia by means of alert thresholds; - maintain ambient air quality where it is good and improve it in other cases.

As a couple of examples, WestJet is sitting with a break-even load factor in the low 70s, around 72 or 73 per cent. On the U.S. side, Allegiant Air, which is considered one of the more efficient U.S. carriers, is sitting with a break-even load factor in or around that same amount.
