The Sustainable Development Goals (SDGs) were established by the United Nations in 2015 as a call to action for individuals, teams, projects, organisations, and industries. The UK is at the forefront of delivering the 2030 agenda for sustainable development (HM Government, 2019). The practice of sustainability involves understanding the ways individuals and teams in projects and organisations respond to the sustainability targets set nationally and internationally. There remains little empirical research exploring the ways in which sustainability is interpreted and practiced by sustainability practitioners, including those whose job title infers direct responsibility (e.g., sustainability consultants, sustainability managers, environmental managers, BREEAM managers, etc.).
