A halt to oil and gas leasing on federal lands announced Wednesday by President Joe Biden was met with a predictable mix of reactions across western Colorado’s gas patch. The moratorium on new leasing was one of several executive orders signed by the president as part of a sweeping initiative aimed at tackling climate change through land conservation, pollution controls and a strong push toward renewable energy resources. The response was swift from Colorado’s energy sector and industry supporters who opposed the move to close off public lands from new leasing, and from numerous environmental groups who praised the move.
