The campaign, which aims to ease tensions between the two groups, will allow for businesses to participate by using posters on their terraces, provided as part of the initiative.

Speaking during the Monday press conference, François Koepp, the secretary general of Horesca, a trade group for Luxembourg’s hospitality industry, explained that the regulations recently hurt the sector. “Both the ban on smoking and the increase in VAT have hit our sector hard,” he said. “In addition, today's customers have new requirements that no longer resemble those of yesteryear.”

Since January 2014, it has been forbidden to smoke inside of cafés, restaurants and clubs. Yet, so far this has not included their terraces.

Two opposing petitions had circulated in recent years as a result: the first, to ban smoking on terraces, highlighted the health risks for passive smokers; the second defended smokers’ rights, citing the economic importance of smokers as clients. Both petitions collected more than the required 4,500 signatures and were thus debated in parliament. As a result, it was decided not to ban smoking on terraces.
