An oil and gas company has filed a lawsuit to block Colorado's orders that require it to halt certain operations and pay $8 million in penalties, arguing these measures constitute an unconstitutional taking of property without compensation. The lawsuit targets new regulations aimed at reducing greenhouse gas emissions from pipeline networks by 20.5% from 2015 levels by 2030. Meanwhile, the Alaska LNG Project LLC successfully maintained its non free-trade export license after a federal appeals court upheld the Department of Energy's authorization. Environmental groups lost their challenge against the Alaska LNG exports when the D.C. Circuit rejected their opposition to the Department of Energy's reapproval of the $44 billion liquefied natural gas project in Alaska. Additionally, conservation groups have filed a new lawsuit seeking to vacate the U.S. Forest Service’s approval of a natural gas pipeline, arguing the agency failed to justify why the pipeline must cross federal lands in Idaho and Wyoming.
