“Compostable” Product Truths & Lies

Making “Compostable” Products Truly Compostable (start time: 0:56)  You’ve probably wracked your brain at some point trying to figure out whether the compostable-labelled clamshell or the green-tinted plastic cup you got at a restaurant is truly compostable.  Many products contain misleading and outright false claims, leaving consumers confused about how to do good by the planet.  Indeed, tons of food and yard waste, as well as organic food-packaging products, end up in landfills, where they decompose under anaerobic conditions and generate methane, a greenhouse gas far more potent, if shorter-lasting, than carbon dioxide. Organic waste from landfills and wastewater is the third largest source of human-related methane emissions, after livestock and oil and gas emissions, according to the Rocky Mountain Institute.
On this week’s show, host Susan Moran interviews Dan Matsch, the director of the Compost Department at Eco-Cycle in Boulder; and Nora Goldstein, editor and publisher of BioCycle, about a new  product-labeling law in Colorado and other efforts to hold product manufacturers accountable, and to clean up the waste stream.

COP28 Climate Summit: Pledges & Realities

Climate Change & COP28 (start time: 1:30) A major global climate conference is taking place now in Dubai, amidst a year of record-breaking heat, wildfires, floods and more around the world.  COP28 is short for the 28th Conference of the Parties of the United Nations Framework Convention on Climate Change. The aim of the conference is to have nations address climate change by pledging to cut greenhouse gas emissions (and actually following through), investing more in clean energy, and having richer nations help fund climate-adaptation measures in developing countries and especially vulnerable communities. Our guests today are Dr. Alice Alpert, a senior scientist at Environmental Defense Fund who previously served on the U.S. delegation to some COP conferences; and science journalist Tom Yulsman, who directs the Center for Environmental Journalism at CU Boulder.

Methane Emissions From Natural Gas

Methane Madness (start time: 2:20)  More than a decade ago, scientists noted that the area where Colorado, New Mexico, Arizona and Utah meet, known as Four Corners, appeared to be emitting a curiously large amount of methane. In a new study, a team of scientists have traced the source: more than 250 gas wells, storage tanks, pipelines and processing plants associated with oil and gas development in the San Juan Basin. The basin is one of many places where new drilling technologies, including horizontal drilling and hydraulic fracturing, have propelled a boom in natural gas extraction. The boom has transformed the U.S. energy mix. Our two guests discuss with hosts Daniel Glick and Susan Moran the science and public health aspects of this study as well as the human side of living near natural gas wells in Colorado. Dr. Colm Sweeney co-authored the recent Four Corners study. He is the lead scientist for NOAA’s Earth System Research Lab Aircraft Program, and he is a research scientist with the Cooperative Institute for Research in Environmental Sciences, or CIRES, at the University of Colorado Boulder. Our other guest, Dr. Christopher Clack, is a physicist and mathematician with CIRES whose research focuses on renewable electricity. He shares his personal experience with and documentation of natural gas extraction.
