The United States formally withdrew from the Paris Agreement, triggering worldwide reactions. Such a decision could have immense environmental and political consequences, including a possible increased strain on international relations. It is feared this move might weaken the accord's global influence on climate change mitigation.

In Japan, the US's decision to leave the Paris Accord caused significant concern, as Japan values international cooperation in combating climate change. The issue has acquired widespread attention, reflecting the Japanese public's commitment to environmental conservation and their disappointment with the US's decision.

In contrast, this issue would be handled differently in the EU. Rather than retreating from international agreements, EU nations tend to strengthen their commitments in the face of significant global crises like climate change.
