Kyoto, Japan -- Global climate action based on the Paris Agreement is progressing, but concerns have been raised that the future projections and scenarios forming the scientific basis for these actions are biased toward a limited number of regions and research institutions.

Climate research teams have created long-term climate mitigation scenarios known as integrated assessment models, which map the technological feasibility of climate change countermeasures, their associated costs, and their long-term effects. Many of these are model comparison projects, a method in which research teams from multiple countries and institutions conduct model simulations based on similar experimental settings and compare the results.

However, only a limited number of research teams can participate in these projects, and the inevitable result is that they do not adequately reflect diverse global perspectives, in particular those of developing countries.
