The integration of international financial systems can help channel capital toward renewable energies, cleaner technologies, and other environmental solutions. This is the conclusion of a study from the University of Sharjah, published in the journal Letters in Spatial and Resource Sciences, which analyzed data from 41 of the largest carbon dioxide-emitting economies for more than two decades. The researchers identified a positive association between financial globalization and green investment, both in the short term and in the long term.
According to the results, a 1% increase in the financial globalization indicator is associated with a 2.81% growth in green investment in the short term and 3.14% in the long term. The authors also found a positive relationship between economic growth and long-term green investment, as well as a favorable contribution from information and communication technologies.
These results point to the importance of international financial flows in mobilizing resources for environmental projects, although they do not allow us to conclude that financial globalization is, in itself, responsible for the increase in investment.
The analysis identified differences between regions. The long-term association was stronger in Europe, followed by the Americas and Asia. The researchers relate the European result, partly, to the existence of stronger institutions, specific climate policies, and more developed sustainable finance markets.
The comparison suggests that the environmental benefits associated with the international circulation of capital also depend on the rules, institutions, and financial systems that guide that investment.
Based on these results, the team advocates greater cooperation among countries and financial institutions, including the creation of international funds dedicated to clean energy projects and to technological development. The study also points to the potential of green bonds and clearer climate-related financial policies.
However, the authors emphasize that mobilizing international capital must be accompanied by effective regulation and measures to prevent greenwashing, i.e., practices that present activities or investments as environmentally sustainable without that claim being adequately substantiated.
The researchers acknowledge limitations in the analysis. The model used assumes a linear relationship between the variables, although macroeconomic phenomena can evolve in a non-linear manner. In addition, green investment was measured through patents for environmental technologies, an indicator that does not encompass all forms of investment actually undertaken.
Thus, the authors recommend further research that distinguishes different dimensions of financial globalization and allows a better understanding of its relationship with the transition to a low-carbon economy.
