In the fourth episode of Policy Driven, co-hosts Tom and Mark are joined by entrepreneur and strategist Louis Lammertyn, co-founder of BookBetter and a founding member of the Green Mobility Magazine Editorial Board. Together they explore how travel and tourism can align with Europe’s climate ambitions while remaining accessible, affordable and enjoyable.The discussion ranges from Louis’s early work with Moonlight Express, Belgium’s first night train operator, to his current efforts to decarbonise tourism through sustainable aviation fuels and more mindful travel choices. Against the backdrop of record visitor numbers, new players such as Nox Mobility, and growing public concern about over-tourism, the episode asks how Europe can make low-carbon tourism both practical and desirable, and what it will take to achieve it.
