Starting in 2021, People for Earth, in collaboration with The Seoul Institute (from the 1st to 3rd sessions) and Gyeonggi Research Institute (from the 4th session onwards), hosts the Climate Change Colloquium. This event aims to facilitate discussions among domestic and international experts on various critical aspects of the current climate system, which is striving to achieve net-zero carbon emissions by 2050. The colloquium delves into topics such as the causes and background of this new climate system, the level of risk associated with specific situations, strategies to prevent surpassing tipping points in each domain, and the imperative for adapting and transforming our way of life and culture. The colloquium continues to evolve with the objective of enhancing public awareness while exploring alternative approaches during this transitional period.
