In collaboration with colleagues at Newcastle Business School (Northumbria University) and the York Management School (University of York), we have established an informal research group in Social and Environmental Accounting and Reporting (SEA/R).

Our research output presently involves two key themes: sustainability indicator disclosure in corporate reporting (with a focus on the coffee industry) and the regulation of corporate reporting (with a focus on the UK’s SRDR regulation). This year, one of our papers was published in the respected Sustainability Accounting, Management and Policy journal.

We embrace opportunities to collaborate with our academic partners so that we may facilitate knowledge transfer between academia and industry, contribute to the body of knowledge furthering Sustainable Development, and bring research to our consulting.
