Burger King announced on Tuesday it was launching an initiative to fight climate change by cutting back on its beef cows’ flatulence — an issue that famously concerns Rep. Alexandria Ocasio-Cortez.

The fast-food giant unveiled the plan on social media with a music video in which a yodeling child cowboy explains how feeding cows lemongrass can reduce livestock’s sizable contribution to greenhouse gas emissions.

cow farts & burps are no laughing matter. they release methane, contributing to climate change. that’s why we’re working to change our cows’ diet by adding lemongrass to reduce their emissions by approximately 33%. learn about our ongoing study: https://t.co/kPCXpjfbGL #CowsMenu pic.twitter.com/DnmF8gVVL0

In a follow-up video that Burger King posted to Twitter on Wednesday, company officials and scientists further explained the science behind their “solution.”

the best kind of change is the kind everyone can be part of. that's why we're making our #CowsMenu open-sourced, so farmers, beef suppliers and other brands can leverage this work. check how industry experts are teaming up to help make this idea a reality: https://t.co/kPCXpjfbGL pic.twitter.com/WzTZA0PVsc

The reaction: Burger King’s announcement was widely celebrated on Twitter as an example of “corporate responsibility.”

• The tweet was liked more than 16,000 times, and the cowboy video racked up 2.2 million views. 

But conservative commentators were less impressed by Burger King’s participation in “Woke Capitalism.”

“Humanity is doomed,” tweeted Sen. Ted Cruz, a Texas Republican. 

Tim Young called the ad campaign “a complete waste of money on marketing for some stupid virtue signaling.”

Literally no one gives a shit that Burger King is reducing cow farts... what a complete waste of money on marketing for some stupid virtue signaling. #COWSMENU

Others recalled how an initial outline of Rep. Alexandria Ocasio-Cortez’s Green New Deal proposal in 2019 named “farting cows” as an obstacle to reaching “net-zero emissions” in 10 years. 

• The New York Democrat later clarified that her plans to overhaul the economy for social justice wouldn't “get rid of agriculture” or “force everybody to go vegan."
• But she said Americans should cut back on hamburgers.
