Admiration for New Mexico’s efforts to reduce harmful light pollution pleases astronomers.

An organization dedicated to preserving natural night skies worldwide has acknowledged the efforts of an oil and gas company in New Mexico to minimize the impact of excessive outdoor lighting. DarkSky International, which advocates for maintaining views of star-filled skies, recently granted certification to Franklin Mountain Energy for their initiative to reduce light pollution at their oil and gas facilities.

This recognition marks the organization’s first certification of energy sites actively working to combat light pollution. Franklin Mountain Energy, based in Denver, has implemented lighting upgrades at two existing sites and at a newly established facility located within a prominent oil production area in southeastern New Mexico.

These projects are anticipated to significantly diminish skyglow, particularly in areas such as Carlsbad Caverns National Park, a renowned site for stargazing and nighttime activities like hiking.

“It doesn’t do anything to impact their bottom line — it actually makes the workplace safer,” said Peter Lipscomb, vice chair of the New Mexico chapter of DarkSky International, because sensible lighting reduces direct glare that otherwise can make it harder for workers to see.

“Being rewarded by (seeing) the dark skies of our ancestors, all those things together, it’s a winning combination.”

Franklin Mountain Energy cofounder Audrey Robertson said the lighting changes reduce electricity consumption. The company said in a statement that it worked on the effort with an alliance of federal land and parks agencies, telescopic observatories and the New Mexico Oil and Gas Association. Recommendations from the alliance include equipment that directs light downward onto work areas and limits light that is cast upward into the sky.

Stargazers worldwide are grappling with the encroachment of outdoor lighting at night.

A 2023 study that analyzed data from more than 50,000 amateur stargazers found that artificial lighting is making the night sky across the world about 10% brighter each year. As of 2016, more than 80% of the world lived under light-polluted skies that obscure the Milky Way.

New Mexico state lawmakers are drafting a proposed update to a 1999 law that regulates outdoor night lighting in the state’s high-altitude mountains and desert. The initiative responds to a rapid increase in light pollution amid advances in energy-efficient LED technology that has spurred more outdoor night lighting that is often unshielded.

The National Park Service has set the protection of dark night skies as a priority at remote locations including the Chaco Culture National Historic Park, an area of New Mexico that Native Americans consider sacred. More than 99% of the park has no permanent outdoor lighting.

Lipscomb also credited oil operators in West Texas that are embracing changes to protect starry skies in collaboration with the McDonald Observatory, near Fort Davis, where research and education depends on dark nights.
