Aaron Smith, a leading expert on the economics of manure digesters, discusses how large concentrated animal feeding operations (CAFOs) in the US are increasingly turning waste into fuel and what the future holds for this nascent industry.
A global shift to mostly plant-based diets with minimal processed foods and red meat, coupled with a large decrease in food waste, would decrease greenhouse gas emissions by more than 85% by 2050 compared to 2020 agricultural emissions, according to a new study.
The Trump administration this week announced the official demise of the endangerment finding, a 2009 determination that six greenhouse gases are harmful for health that gave the US EPA legal backing to set emission standards for cars, trucks and power plants under the Clean Air Act.
Diets around the world dependent on ultra-processed foods and animal-based agriculture are driving obesity rates and climate change, but solutions exist that would bolster health, and save money and the planet, according to a new review.
Tyson Foods will stop asserting it is pursuing production of “climate-smart” beef and working to reduce harmful greenhouse gas emissions as part of a legal settlement of a lawsuit that challenged the veracity of the company’s environmental claims.

Heat-trapping emissions released over more than a century and a half by the world’s largest fossil fuel and cement producers are projected to cause global sea levels to rise about one to two feet through the year 2300, even if future emissions are drastically cut, according to new peer-reviewed research.

US power plants, the largest stationary sources of greenhouse gases in the nation, continue to show reduced emissions but the good news from that sector comes as oil and gas emissions rise, according to new regulatory data.
On a recent hot August evening, residents of the tiny rural community of Universal, Indiana packed into a public meeting to barrage operators of a proposed fertilizer plant with an array of concerns about what risks the project may pose for their health and the surrounding environment.
