HELENA, Mont. -

Three conservation groups are appealing a judge's dismissal of their lawsuit seeking to block nearly 80,000 acres of oil and gas leases scattered across Montana.
    
The Montana Environmental Information Center, WildEarth Guardians and Earthworks' Oil and Gas Accountability Project are seeking to force companies to reduce greenhouse gas emissions when they drill oil and gas fields.
    
They want the Bureau of Land Management to require companies to cut methane emissions as a condition of their leases.
    
The groups filed an appeal Wednesday with the 9th U.S. Circuit Court of Appeals after U.S. District Judge Sam Haddon rejected their lawsuit in June.
    
Haddon ruled emissions from drilling those leases would not raise global greenhouse gas levels to a point that would hurt their "recreational and aesthetic interests" in the nearby lands.
