Using news articles to identify emerging trends in Net-Zero societies related to technologies, policy and regulatory

Abstract

Regarding ESG investments, which is one of the investment methods to evaluates cooperate environmental efforts, are becoming the minimum requirement for business. Information disclosure regarding Carbon Net-Zero society has led to the trust of the market and has begun to be directly linked to corporate value. Therefore, in this study, we visualized the relative progress of each decarbonized topic in each country. Specifically, we extracted articles related to decarbonization from about 40 million articles over the past three years, clustered BERT embedding vectors for those articles, and extracted characteristic words for each cluster by using c-TF-IDF. From this study, we found that decarbonization efforts are contrasting in Europe, the United States, China, and Japan. In Japan, we found that although the fields of "fuel ammonia" and "carbon dioxide capture and storage (CCS)" are attracting attention internationally and are leading in technology, they are inferior to other countries in terms of policy and regulation.
