Quality carbon removal credits are in high demand among tech giants such as Microsoft and Google as they work to offset emissions amid rising demand for artificial intelligence. As a result, carbon credits are in increasingly short supply and prices are climbing. The price of durable carbon removal credits has soared, with rates in 2024 reaching nearly four times those of traditional forest-preservation credits.

ReTuna Återbruksgalleria in Eskilstuna, Sweden, claims to be the world's first secondhand shopping mall, exclusively selling recycled, reused or sustainably produced items. Opened in 2015 next to a recycling center, ReTuna streamlines the donation, refurbishment and resale of goods through multiple specialized shops. The mall not only diverts tons of usable items from landfills but also attracts international attention as a pioneering model for sustainable retail.

The International Air Transport Association estimates that airlines will need 165 billion gallons of sustainable aviation fuel annually by 2050 to reach net-zero emissions. However, production in 2024 was only a tiny fraction of that total, driving calls internationally for a rapid expansion of production capacity.

The US residential solar industry is facing a significant transition as the federal Investment Tax Credit phases out at the end of 2025, writes Fox Swim of Aurora Solar. The shift is expected to drive a short-term downturn in demand, with projections indicating a 26% drop in 2026. While the ITC's expiration challenges the industry, it also encourages innovation and operational efficiency to sustain adoption in a post-incentive landscape, writes Swim.

The Colorado Energy Office has allocated $7.3 million to geothermal heating and cooling projects in Denver, Colorado Springs, Vail and Steamboat Springs, using funds from the Colorado Geothermal Energy Tax Credit Offering. "We are seeing growing interest in geothermal heating and cooling across the state, not only to help us achieve our climate goals but also to reduce energy costs and improve indoor air quality," says Colorado Energy Office Executive Director Will Toor.

Tennessee has implemented an annual surcharge of $100 for hybrid vehicles and $200 for electric vehicles to offset declining gas tax revenue. Critics argue the fee unfairly targets a small group of drivers while ignoring millions of fuel-efficient gasoline vehicles. Alternative funding models, such as fees based on mileage or vehicle weight, are more equitable, according to critics.

The Environmental Protection Agency has revised the Waters of the United States rule to provide clearer definitions and regulatory terms, addressing concerns from landowners and farmers about federal overreach. The update, drawing from a Supreme Court decision, aims to balance environmental protection with economic growth by clarifying terms like "relatively permanent" and "tributary," and by excluding certain types of land and water.

Local restrictions on wind and solar are gaining momentum in many parts of the US, but residents of Richland County, Ohio, may be ready to push back. They are challenging a ban on wind and solar projects -- and will have the opportunity to vote against the rules in a first-of-its-kind referendum in May. "Lawmakers should be looking to repeal it and make a system that actually responds to the problems facing our electric grid right now," said Chris Tavenor of the Ohio Environmental Council.
