Republicans are criticizing Manny Rutinel, a Democratic candidate for Congress in Colorado's 8th Congressional District, over a 2022 paper he co-authored that suggested livestock should be a more significant target for climate change mitigation than fossil fuels. The paper argued that achieving climate goals would be difficult without substantial reforms to the food system.

"Simply put, achieving the Paris Agreement goals will be nearly impossible without ambitious policies that reform our food system," Rutinel wrote in the paper with the Environmental Law Institute. "Despite the growing awareness of animal agriculture’s climate impact, climate policy and action have historically focused on electricity and fuel use."

The resurfaced paper has become a point of contention for Rutinel as he seeks to represent a district with a significant agricultural and ranching presence. Colorado's 8th district is the state's leading producer of beef cattle and dairy, with agriculture and livestock operations occupying 75% of its 2.5 million acres, according to Upstate Colorado Economic Development.

Rutinel has recently sought to reassure voters of his understanding of the industry's importance. "Colorado ranchers are my friends and neighbors, and I’ve gotten to know them," he stated. "They’re good stewards of the land, they care for their animals, and they are the backbone of our economy and our communities."

However, his past advocacy, including statements made in college and to local government, has emphasized the role of livestock in global emissions. The paper further detailed his proposals for government intervention.

"Governments can require that agribusiness internalize the environmental, public health, and animal welfare costs of animal farms through regulations, mandates or taxes," Rutinel wrote. He also suggested that governments could finance projects to offset emissions, drawing a parallel to carbon offset credits used by manufacturing facilities.

Some critics have characterized Rutinel's past positions as further left than mainstream Democratic climate initiatives. "Meatless Manny's vision to ban ranching would not only lead to catastrophic job losses in Colorado but also cause a beef shortage across America," stated Zach Kraft, a spokesperson for the Republican National Committee.

Rutinel, who has advanced past the Democratic primary, is set to face Republican incumbent Rep. Gabe Evans in the general election on November 3, 2026. Rutinel's campaign did not immediately respond to a request for comment on whether his views on the necessity of change within the farming industry for climate reform have evolved.
