The problem of climate change is one of the most crucial issues today. The emergence of increasingly obvious threats, has raised concerns for people around the world, coupled with the withdrawal of the United States as one of the world’s largest emitter gas contributors who decided to leave Paris Agreement during the Trump administration, has had a bad impact on efforts to tackle the problem of climate change. The lack of research into the impact of the U.S. withdrawal from the Paris Agreement on tackling global climate issues has prompted the study. This paper will analyze the impact of what has arisen from the U.S. withdrawal from Paris Agreement during the Trump administration, using foreign policy theory in analyzing the actions or policies taken by Donald Trump in the withdrawal from the Paris Agreement, the concept of environmental security in analyzing the impact of withdrawal policies that occur against the environment and the Theory of International Regimes initiated by the Paris Agreement. Stephen Krasner analyzes the world’s climate change regime. The method used in this research is a qualitative research method with explanative writing techniques. This study shows that there are three main impacts as a result of the Withdrawal of the United States from the Paris Agreement, among others, the increase in global emissions that are bad for the environment, which is indicated by increased activity that produces gas emissions in the United States region. Second, the decline of climate finance mechanisms that will affect the quality of climate change reports produced. Third, this withdrawal will also affect global climate governance, which will certainly affect member countries’ compliance with the agreement.
