Tyson Foods announced this morning that it will strive to achieve net-zero greenhouse gas emissions across its global operations and supply chain by 2050.

Why it matters: Tyson is the largest meat producer in the United States. And agriculture, including livestock and manure emissions, is the largest source of methane emissions in the U.S.

Context: The announcement marks a step forward from Tyson's previous commitment, made in 2018, to reduce greenhouse gas emissions 30% by 2030.

What's happening: In a press release, Tyson outlined specific goals to meet along the way.

  • Update the baseline for emissions to align with limiting global temperature rise to 1.5℃, consistent with the Paris Agreement, by the end of 2023.
  • Establish a pathway to using 50% renewable energy across its domestic operations by 2030.
  • Target 2 million feed acres for land conservation, and expand total acres by 2025.
  • Increase the company's grazing lands target for sustainable beef production practices by 2025. The current target is 5 million acres.
  • Eliminate deforestation risk throughout its global supply chain by 2030.
  • Support climate action policies through advocacy groups such as the Net Zero Business Alliance.

What they're saying: John Randal Tyson, chief sustainability officer, tells Axios the biggest challenge is making sure the millions of people Tyson works with are working toward the same goal.

  • Between 80 and 90% of Tyson's greenhouse gas emissions come from "indirect upstream and downstream emissions that occur in the value chain," he says, such as on farms.

UN climate summit warning signs are adding up

There are growing signs that make-or-break climate talks in Glasgow, Scotland, this fall won’t produce tangible plans for emissions cuts that keep the Paris agreement’s targets viable.

Why it matters: The climate summit is billed by world and environmental leaders as the last, best hope for securing the global commitments needed to get countries on track to avoiding potentially catastrophic levels of climate change during the next several decades.

A federal judge on Tuesday temporarily blocked South Carolina's ban on mask mandates in schools, ruling that it discriminated against students with disabilities and violated the Americans with Disabilities Act.

Why it matters: As mask bans extend to public schools around the country, parents and disability rights activists have sounded alarm bells. The ruling may signal the outcomes of legal fights playing out across the country.

Florida Gov. Ron DeSantis took legal action on Tuesday to try to stop the Biden administration's immigration plans.

Why it matters: The Republican governor, who is running for re-election next year and is possibly eyeing a 2024 presidential bid, is picking a high-profile fight with Biden while re-upping his hardline stance on immigration.
