News Briefing 
        Since the United States confirmed it would return to the Paris Agreement on Climate Change and clearly set the target for greenhouse gas reduction (50% to 52% reduction as compared to that of 2005) by 2030, the newly-inaugurated President, Joe Biden, has drastically changed the country's attitude towards environmental issues since he took office.

Impact Analysis 
       Several countries around the world have successively announced specific carbon reduction targets in recent years. However, many countries are still not committed to the cause due to the influence of the United States as a major carbon emission country as it serves as a benchmark to the rest of the world. The most important significance of this summit is that the world has finally reached a strong consensus on carbon reduction following the clear and definite stance of the United States. Even if the baseline year for comparison between countries differs, 2030 as the target year has already been specified, and it will put pressure on those countries that remain stagnant. Additionally, the new stance should exert a sense of direction regarding the development of industry and technology.
