ESG (Environmental, social, governance) factors are widely known as the three primary factors in measuring the sustainability and societal impacts of an investment in a company or business. This repoitory proposes a quantitative approach to measuring the ESG premium in stock trading using ESG scholar data. The alternative data we use is from the Microsoft Academic Graph database, which is an open resource database with records of publications, including papers, journals, conferences, books etc. It provides the demographics of the publications like public date, citations, authors and affiliated institutes. It includes ESG publication records dating back to 1970s - long enough to study the relationship between ESG publications and companies' stock prices.
