This paper considers the extent to which the Northeast Asian countries - China, Japan, South Korea, and Taiwan - are collaborating as a legitimate group to produce “green” R&D. Forcing a revision of traditional institutional analysis, such collaboration efforts can overlap with existing policies of regional coordination, but they can also pave the way for future, formal coordination efforts. Employing a mixed methods approach which triangulates data based on expert interviews as well as green patenting output over the last 33 years, it is confirmed here that the presence of the Northeast Asian environmental regime is strongly associated with the development of green R&D among countries in the region. It can be further confirmed that Northeast Asia is on the cusp of becoming a genuine counterweight to the existing dominance of the U.S. and Western Europe.
