"India, the United States, and Diverging Climate and Energy Norms" by CWP alum Manjari Chatterjee Miller

February 20, 2026

The Trump administration has just announced it will revoke a policy from the Obama era that declared carbon dioxide and other greenhouse gases a threat to public health and welfare. That declaration of endangerment had served as the legal foundation for almost all climate regulations put in place since 1970 by the Clear Air Act, which regulates many sources of pollution such as power plants and motor vehicles.

The revocation aligns with the administration’s skeptical approach to climate and energy norms. President Donald Trump has himself called climate change a “hoax” and green energy a “scam.” Since he took office in January 2025, the U.S. government has centered its climate and energy policy on expanding fossil fuel production while rolling back climate regulations and renewable energy support. The Heritage Foundation’s Project 2025, following the principle that Biden-era climate regulations “[impoverished] Americans and [made] China rich,” provided the Trump administration with a blueprint for such policies: nearly two-thirds of Trump’s early executive actions mirrored proposals from Project 2025.

The U.S. volte-face on climate and energy norms and global leadership has implications not just for the liberal international order but for countries such as India that have, in the past, been themselves recalcitrant on such norms. Today, particularly in comparison with the United States, India seems positively forward-facing, making an astonishing pivot on previous climate and energy policies while at the same time emphasizing its national and security interests. This turnaround has also led to tension with the Trump administration—particularly on oil energy and India’s reliance on Russian oil.
