Indiana now classifies natural gas and propane as clean energy under a new state law.
Gov. Mike Braun signed Senate Bill 178, granting the fuels eligibility for tax credits and other incentives.
Sam Carpenter, executive director of the nonprofit Hoosier Environmental Council, opposed the measure, arguing the fuels significantly contribute to climate pollution.
"Methane is around 38 times more potent as a greenhouse gas," Carpenter pointed out. "What happens is there's a lot of leakage that happens in the drilling, in the extraction, the storage, the transportation, even the burning of methane."
Proponents of the bill argued it supports an "all of the above" approach to reduce energy costs for Hoosiers.
Carpenter cautioned investing in natural gas infrastructure could backfire. He noted the high costs and slow pace of building pipelines and transmission systems. He also emphasized Indiana's energy landscape is already shifting.
