Wyoming Governor Matt Mead signed legislation on Monday approving $34.5 million in cuts to the state’s K-12 education budget. The new spending plan also denies tax increases that would raise additional money for education, though it does establish a special committee to determine future modes of funding. Ultimately, the legislation seeks to address a shortfall in Wyoming’s education budget that could reach $1.8 billion by 2022.

“We’re going to need to think about funding education as a Chevy rather than a Cadillac in the future,” Jillian Balow, the state superintendent of public instruction, told The Casper Star-Tribune back in December.

Beyond overspending, there’s a larger explanation for why these budget cuts are necessary. The majority of Wyoming’s funding for public education comes from taxes and other revenue sources that depend on the state’s declining oil and coal industries.

In 2016, the U.S. Department of Energy reported that coal production had reached its lowest point in 35 years, forcing many coal companies to declare bankruptcy. Oil prices in the U.S. have also fallen from $99 a barrel in 2014 to $30 a barrel in January 2016.

As these industries struggle, states that depend on them like Wyoming, Alaska, and Oklahoma are forced to cut spending for education. According to data from 2011-2012, around 30 percent of Wyoming’s education spending comes from federal mineral royalties, while another 30 percent comes from property taxes often backed by these minerals.
