Delta Air Lines and Shell Aviation signed a five-year contract in mid-July running through 2030, expanding sustainable aviation fuel supply across five hub airports spanning the country, from LAX to Boston Logan. Notably, the announcement never leads with a gallons figure, the number most SAF deals are built around. That's because most SAF deals are offtake agreements: an airline agrees to buy fuel a producer promises to make, often years before the plant exists. United Air

Tomago Aluminium's problem was not abstract. Its 40-year electricity contract with AGL, tied to the Bayswater coal plant, expires in December 2028, and power already eats more than 40% of what it costs to run the smelter. Buying replacement electricity at open market rates would have made Tomago uncompetitive against smelters overseas, and the company had already signaled it was preparing to close by the end of 2028, a move that threatened over 1,000 direct jobs and roughly 5

When you hold a cup of coffee, you see 125 milliliters of liquid. What you don’t see is the 140 liters of water required to grow, harvest, and process those coffee beans. This hidden volume is known as Virtual Water, which is the freshwater embedded in the production of everyday commodities, agricultural goods, and manufactured items like coffee. As climate change intensifies localized water stress, the virtual water trade has quietly become one of the most critical levers in

The public comment window on the SEC's proposal to erase its own climate disclosure rule closed yesterday. That rule was adopted in March 2024 and stayed within weeks, so it never took effect. Europe reversed course as well by lifting the CSRD threshold to companies above 1,000 employees and €450 million in turnover, a change estimated to remove about 90% of expected filers. California pushed its first emissions filing from August 10 to a proposed November 10. The shifting ex

In September 2019, Enel sold a $1.5 billion bond with an unusual clause. If the Italian utility missed a renewable capacity target by the end of 2021, it would owe bondholders an extra 25 basis points every year to maturity. That was the world's first sustainability-linked bond (SLB). The idea came from Alessandro Canta, Enel's Head of Finance and Insurance, who had concluded that green bonds made the company do its work twice. A green bond meant carving out a subset of proje

Facility operations for ice hockey practice rinks encompass several integrated systems designed to maintain a safe, efficient, and comfortable environment for training and recreational use. Key areas include the building envelope, air conditioning and dehumidification, ice-freezing refrigeration systems, Zambonis, and stadium lighting. The building envelope serves as the primary barrier for thermal and moisture control. It emphasizes tightness more than thermal insulation t

LG Electronics is redefining television innovation with a strong focus on environmental responsibility across every stage of the product journey. From material sourcing to daily operation and responsible disposal, the company demonstrates how premium entertainment can align with sustainability goals. LG prioritizes sustainable materials in upstream production. Its OLED panels eliminate backlights, slashing plastic use by up to 90% compared to traditional LCD models. For 202

Businesses navigating operational net-zero goals should utilize a series of tools to deliver on those goals. Carbon reduction strategies vary widely in effectiveness, additionality, and long-term value. This ranking helps organizations allocate resources wisely, starting with prevention and progressing to compensation. Operational reductions lead, followed by direct utility REC matching, followed by other REC approaches and carefully selected carbon offsets including direct a

Windows shape a building’s energy footprint more than many people realize. They balance natural light, views, and comfort while playing a critical role in heating and cooling efficiency. In an era of rising temperatures and utility costs, investing in better windows delivers immediate and lasting benefits. On hot days, gaps or poor seals where the window frame meets the walls, allows conditioned air to escape and hot outdoor air to infiltrate. This can increase energy use by

Municipal public transport is a powerful alternative to passenger vehicles, delivering efficiency, reduced congestion, and major environmental gains. While personal cars dominate many commutes, cities that build financially viable buses, light rail, and subway systems win on multiple fronts. Public transit slashes emissions dramatically on a per passenger-mile basis. Passenger vehicles emit around half a pound of CO2 per passenger-mile for single occupancy, while well-utili

The construction industry faces mounting pressure to cut GHG emissions, with buildings accounting for nearly 40% of global output. Traditional demolition generates massive waste, but advancements in deconstruction and circular practices are transforming how we handle building end-of-life and tenant renovations. The concept of “material passports” would make every building component carry a digital identity documenting its origin, composition, carbon footprint, and structura

Hotels present one of the best opportunities for sustainability. They consume large volumes of energy keeping rooms at perfect temperatures around the clock, driving up costs and GHG emissions. Smart AI systems now automate cooling to match check-in and check-out schedules, delivering comfort only when needed, slashing unnecessary usage. This targeted approach transforms HVAC operations. Sensors detect occupancy, integrate with booking systems, and adjust temperatures dynam

Urban heat islands transform bustling cities into intense heat traps. Dark pavements, roofs, and dense buildings absorb solar energy and radiate it back, driving local temperatures several degrees higher than surrounding rural areas. This phenomenon spikes air conditioning demand, elevates GHG emissions, degrades air quality, and escalates health dangers especially for vulnerable populations during heat waves. As climate pressures mount, effective mitigation has become a crit

Dairy cows produce substantial methane by burping the products of enteric fermentation occurring in the digestive tract, a key source of agricultural GHG emissions. Innovative feed additives provide an effective mitigation path, reducing methane while opening revenue streams through carbon credits. There are various solutions that help farmers lower their environmental footprint without sacrificing productivity. DSM-Firmenich stands out with its groundbreaking Bovaer, which

Not every company requires a formal sustainability function or a dedicated team to minimize its environmental impact and adhere to sustainable practices. Consider Rogue Fitness which is a manufacturer of fitness equipment including barbells, bumper plates, pull-up and squat racks, kettlebells and everything a functional fitness or home gym could need. Rogue Fitness, with its tight supply chain, high-quality over-engineered products, and proximal customers, is oriented towards

Batteries on the electricity grid serve critical purposes to meet the explosive demand for clean and reliable electricity needs. Battery units can be paired with renewables to create an even dispatch of power into the larger electricity grid, achieving 95%+ capacity factors. They can also be used on-site to minimize the need for utility power. Pairing these two technologies mitigates the intermittency issue inherent in renewable power generation. Batteries also provide a te

Data centers powering the AI boom face rising local opposition, like wind farms and nuclear plants before them. Concerns over noise, visual impact, massive energy and water use, grid strain, and higher electricity costs for residents drive NIMBY resistance in hotspots like Northern Virginia and parts of Texas. Wind projects often spark complaints about landscape alteration and intermittent power, while nuclear faces deep-seated safety and waste fears despite its low-carbon

Demand Response (DR) programs are critical mechanisms that allow utility companies to meet electricity demand especially during peak demand windows. At these critical moments, a DR event occurs and the utility will pay participants to shift or stop using electricity. DR assists with both the economic function of the electricity system and supports reliability. Participants can include industrial users that curtail manufacturing processes, commercial users that reduce HVAC and

Behind-the-meter (BTM) electricity production lets businesses generate power on their own side of the utility meter, bypassing traditional grid reliance for greater control and resilience. BTM systems gained fresh momentum as AI-fueled data center demand strained the grid. While small-scale solar added steadily to renewables, the primary surge came from corporate on-site solutions. Data center developers sidestepped years-long interconnection queues by installing generators,

The sustainability of the transportation sector is bright, especially when considering the proliferation of self-driving vehicles. Although the transition and electrification will take time, resource use to satisfy personal and commercial vehicle transport should plummet. Automated driving will completely reshape the vehicles themselves as driver input is no longer needed. Steering wheels, shifters, and even pedals will become obsolete, reducing resource needs in production
