Cody Two Bears on Indigenized Energy's Community-Centric Grid Strategy

July 21, 2026 • 55 mins
Tribal households in the United States carry an energy burden 28% above the national average and endure 6.5 times more power outages a year, and roughly 17,000 tribal homes — housing at least 54,000 people — have no electricity at all, according to the Department of Energy. Those are the communities now first in line to absorb the next surge in demand, because Energy Information Administration concluded data center load...

GoodPower’s Leah Qusba on Selling Clean Energy as Pocketbook Power

July 13, 2026 • 49 mins
In 2024, 91% of new large-scale renewable projects around the world made electricity for less money than any fossil-fuel option, according to the International Renewable Energy Agency. Solar power was 41% cheaper than the lowest-cost fossil fuel, and onshore wind was 53% cheaper. The technology that can lower energy bills, keep the grid stable, and create jobs is now the most affordable way to build power almost anywhere. So, here&...

Sustainability In Your Ear: Shareholder Democracy and Causeway Impact Founders on Building Shareholder Influence

June 29, 2026 • 61 mins
If you hold a 401(k), an IRA, or a single index fund, you own a sliver of hundreds of American companies, yet you almost certainly let someone else decide how those shares vote. Individual investors hold about 25% of all U.S. public equities, more than BlackRock, Vanguard, and State Street combined, yet only about one in eight of them votes the shares they own; the rest of those ballots get cast by a handful of asset managers and t...

Kendra MacDonald Steers to the Blue Economy at Canada's Ocean Supercluster

June 22, 2026 • 44 mins
The ocean produces about half the oxygen we breathe, absorbs roughly 30% of the carbon dioxide we emit, and takes up about 90% of the excess heat those emissions trap, according to the United Nations. It is the planet’s largest life-support system — and also its least-funded one. Of the 17 UN Sustainable Development Goals, the goal for life below water consistently draws the least money. Canada, which has the longest co...

Urban Surfer's Sifiso Gumbi on Organizing South Africa's Recycling System

June 15, 2026 • 48 mins
In South Africa, informal waste pickers recover between 80% and 90% of all plastic and paper that actually gets recycled. There are about 140,000 of these reclaimers, who walk through cities and landfills, pulling trolleys and selling what they collect to make a living. Each person can keep up to 24 tons of material out of landfills every year. Together, they saved municipalities R750 million (about $45 million) in landfill costs i...

Ethan and Desmond Hua Build HOPE for School Uniform Reuse

June 8, 2026 • 43 mins
Most school uniforms are retired while they are still perfectly wearable. Children cycle through them on a predictable annual schedule as they grow, which sends a steady stream of usable clothing toward the landfill at the same moment families on tight budgets are paying to replace what their kids have grown out of. The waste side of that equation is substantial: the EPA estimates Americans generated about 17 million tons of textil...

The Institute of Food Technologists' Brendan Niemira on Why Food Science Is Climate Science

June 1, 2026 • 52 mins
About a quarter of global greenhouse gas emissions come from the food system, but the public conversation about food and climate keeps getting stuck at the two ends of the chain — what farmers grow on one side, what consumers buy on the other. The middle of that chain — processing, packaging, distribution, storage — is where most of the practical climate levers actually live, and it is the part you almost never se...

SiYE Interview - Trex Makes Circularity Work

May 25, 2026 • 50 mins
Less than 2% of Americans can put plastic film in their curbside recycling bin, according to The Recycling Partnership. Meanwhile, the country generates millions of pounds of bags, pallet wrap, bubble mailers, and dry cleaner sleeves every year that machinery at materials recovery facilities is designed to reject. The plastic film problem has been the recycling industry's white whale for three decades — too contaminated for m...

Sustainability In Your Ear: EarthRating's Martin Johnston On Making Sustainability Claims Creditable

May 18, 2026 • 41 mins
A traditional sustainability certification can take six to eight weeks and thousands of dollars in consultancy fees, and still leave purchasers wondering whether the claims actually hold up. Martin Johnston, founder of EarthRating.ai, thinks he can deliver a more useful answer in 10 minutes. His London-based startup is building a universal credibility score for sustainability — a 1,000-point rating, drawn from roughly 100 pub...

Emerald Packaging CEO Kevin Kelly Delivers Recycled Produce Packaging

May 11, 2026 • 46 mins
Americans throw away nearly 5 million tons of film and flexible plastic packaging every year, and less than 1% of it gets recycled, according to The Recycling Partnership. The salad bag, the potato bag, the pallet wrap behind every grocery store — all of it is technically recyclable, almost none of it actually is, and food contact applications make the math even harder, because the FDA requires rigorous migration testing befo...

Sustainability In Your Ear: Zena Harris Brings a Green Spark to Hollywood

April 27, 2026 • 46 mins
An average big-budget movie creates about 3,370 metric tons of CO₂, according to the Sustainable Production Alliance's 2021 report. That’s like driving over 700 gas-powered cars for a year, or about 33 metric tons of CO₂ for each day of filming. A single TV season can have the same impact as 108 cars. With thousands of productions happening every year in North America, Hollywood’s environmental impact is hard to overloo...

In 2024, the global market for eco-labeled products crossed $500 billion. Electric vehicles, bamboo toothbrushes, compostable packaging — the shelves are full of ways to shop your way to a better planet. And yet global carbon emissions hit another record high that same year, and atmospheric CO₂ now stands above 429 parts per million. Decades of research have produced a finding that the sustainability industry doesn't want to ...

Don Carli On Tuning What We See Online To Reduce eCommerce Returns

April 6, 2026 • 49 mins
$850 billion. That's what retail and e-commerce returns will cost in 2026, generating 8.4 billion pounds of landfill waste — and a surprising share of it involves products that worked perfectly. They just didn't look the way people expected. About 22% of consumers return items because the product looked different in person than it did online, and for home goods and textiles, that number climbs higher. The culprit has a name: ...

Sustainability In Your Ear: The XPRIZE Wildfire Competition Heats Up

Every wildfire starts small. The problem is that by the time most are detected, minutes have already passed and, under increasingly common conditions driven by a warming climate, a fire can grow beyond any tanker truck's capacity to contain. The gap between ignition and coordinated response currently averages around 40 minutes. Firefighters have long understood the math: a spoonful of water in the first second, a bucket in the firs...

Cattle are one of the most consequential climate problems hiding in plain sight on the dinner table. Livestock are responsible for roughly 14.5% of global greenhouse gas emissions, according to the United Nations Food and Agriculture Organization, and cattle alone account for about 65% of that sector's output. Most of it doesn't come from manure or land use — it comes from inside the cow. Approximately one billion cattle on t...

Forests are vital for people everywhere. They cover about 4.14 billion hectares, roughly a third of the world’s land, and store 714 gigatons of carbon. They also support 80% of land-based biodiversity. However, we are losing 11 million hectares each year to deforestation, and the World Bank expects demand for forest-based products to rise by 400% by 2050.
