The 2024 United States presidential election marks a pivotal moment in global sustainability and energy policy leadership. With unprecedented stakes, the election outcomes between former President Donald J. Trump and current Vice President Kamala Harris represent divergent paths that will reshape domestic policies and international approaches to climate change, energy production, and sustainable development policymaking. This paper analyzes each candidate’s energy and environmental policies, exploring their potential impacts on the global climate movement, global economic partnerships, and the future of the worldwide green energy transition in both developed and developing economies. Through a comprehensive examination of both candidates’ policy positions, current and previous records, and policy promotions, this analysis highlights how the election will be a global turning point in sustainable development goals. As the world approaches critical environmental degradation and energy demand still increases, the U.S. leadership in this sphere will either drive further progress toward a green future or reinforce traditional energy paradigms with far-reaching consequences. Ultimately, the 2024 election is decisive in determining the trajectory of global efforts toward climate resilience, sustainable development, and energy transformation.
