A new global analysis reveals an unprecedented surge in climate litigation, primarily driven by a wave of protective lawsuits defending existing environmental regulations against rollbacks by US President Donald Trump. While the United States remains the primary hub for these legal battles, the report highlights a global trend of "protective" litigation aimed at preserving established climate policies and pledges rather than pursuing new goals. In 2025, one in five new climate cases in the US fell into this category, marking a sharp increase from Trump's first presidential term.&nbsp;&nbsp;<a href="https://www.wionews.com/videos/us-iran-peace-deal-rubio-reassures-gulf-as-iran-tightens-grip-on-hormuz-1782363448618/embed">https://www.wionews.com/videos/us-iran-peace-deal-rubio-reassures-gulf-as-iran-tightens-grip-on-hormuz-1782363448618/embed</a>&nbsp;&nbsp;This evolving legal landscape is expected to be a critical area to monitor throughout the remainder of 2026. Similar protective lawsuits were filed outside the United States in 2025, notably in Europe and Brazil. Courtrooms are increasingly serving as battlegrounds for climate action, with activists suing fossil fuel corporations and seeking government accountability through international bodies like the International Court of Justice, which recently ruled that states are legally obligated to tackle climate change. Additionally, a French court is set to rule on whether TotalEnergies breached its environmental duties.&nbsp;Also read: <a href="https://www.wionews.com/world/barack-obama-trump-obsession-suite-in-his-head-iran-talks-1782373710664">Barack Obama mocks Donald Trump’s obsession, says he has a ‘suite’ in his head</a>&nbsp;Over the past 40 years, more than 3,600 climate cases have been filed worldwide, with the vast majority occurring in the United States and emerging after the 2015 Paris Agreement.
