Sustainability is the watchword for many organisations when constructing international assignment packages, and assignee benefits present a number of options for making sustainable choices. As transport has such a clearly definable carbon footprint, many companies are starting to look to public transport instead of providing a company car for staff on assignment in major cities. Our latest Benefits for International Assignments policy survey showed that 35% of companies currently provide a public transport allowance to their assignees, with this percentage trending upwards. In qualifying locations, providing a public transport allowance to assignees instead of motoring benefits can be both a cost-effective and sustainable component of an assignment package.
