Starbucks is brewing a goal to become “resource positive” on carbon, water and waste, while eventually moving away from single-use packaging. The aspiration, which lacks a deadline, comes alongside three early sustainability commitments for 2030, all set forth Tuesday in public letter from CEO Kevin Johnson.

Velcro bindings, wheelie suitcases, and the now-ubiquitous InstaPot are all modest examples of refinements to products that existed for decades before anyone thought, “Couldn’t this be better?” The drive […]
Many residential solar installation companies do not have a high-efficiency solar panel strategy other than offering a premium, high-efficiency panel that can be optionally installed at a higher system dollar per Watt price. This is understandable. Running a solar installation company requires sales and installs to be happening like clockwork, with little time left for […]
In recent years, Pennsylvania has become an epicenter of the nation’s hydraulic fracturing boom. But even as production from “unconventional” wells – those using horizontal drilling and fracking – has grown, nearly 90% of the state’s 120,000 active wells are older, “conventional” vertical ones that typically rely on traditional drilling methods. What does that mean […]

As BlackRock Chairman Larry Fink writes in his latest letter to CEOs, “Climate change has become a defining factor in companies’ long-term prospects.” He’s right: the impacts of climate change on businesses are hard to overstate. According to the federal reserve, climate-related events already have cost the U.S. economy over $500 billion in the last […]
Driving in central London is hell. Actually, scratch that. Driving in any major city is hell. We hear a lot about how our cities are designed for cars, but if that is the case who is doing the designing? A misanthropic Heath Robinson who hates clean air and is terrified of speeds that are faster […]
Cities need to lay the groundwork now for the arrival of autonomous vehicles (AVs) to ensure that AVs contribute to rather than detract from their transportation and climate objectives. An ACEEE toolkit highlights fundamental strategies that cities can pursue and gives them a policy roadmap. As cities grapple with transportation challenges, many have started looking […]
