The interplay between “accounting” and “sustainability” or “sustainable development” has spurred a long-standing debate among academics and practitioners alike for decades. During the last 25 years, networks like the Environmental and Sustainability Management Accounting Network (EMAN) and the Centre for Social and Environmental Accounting Research (CSEAR) have played a central role in building research capacity and promoting this research field. Within this topic, the number of publications and researchers has increased, and corporate and practitioner interest is growing continually, but key challenges are also increasing. On a global scale, most global environmental and social sustainability indicators show a negative trend, reflecting the ever-worsening state of our planet (e.g., IPCC 2014; WWF 2016; Sachs et al. 2017).
