The US Supreme Court commenced its new nine-month term on Monday, beginning its judicial proceedings. ExxonMobil and Suncor Energy are attempting to halt a lawsuit initiated by officials in Boulder, Colorado.

Boulder, Colorado officials are seeking monetary damages for harms attributed to climate change. The city and county governments in Boulder accused the two corporations of contributing to climate change and misleading the public regarding fossil fuel risks.

These local authorities aim to hold the companies financially responsible for both past and future costs, including environmental damage and public health issues. Nearly sixty state and local governments have filed comparable lawsuits, seeking billions of dollars from fossil fuel entities.

The Colorado Supreme Court allowed Boulder's lawsuit, which alleges state law violations, to continue after Exxon and Suncor appealed the decision. The Trump administration previously supported Exxon and Suncor, asserting that federal law prevents Boulder from making such claims.

Exxon and Suncor contend that Boulder's claims trespass into an area already managed by the Clean Air Act. Furthermore, disputes concerning President Donald Trump's immigration policies and state bans on assault-style rifles are scheduled for hearing in the coming months.

A ruling from the Supreme Court favouring the companies could result in the dismissal of many of these pending cases. Justice Samuel Alito has withdrawn from participating in the case proceedings.
