Four federal agencies this month unveiled an 88-page roadmap toward a sustainable transportation sector by 2050.

Cape Verde has reached a deal with Portugal to exchange millions of dollars in national debt for investments in a new climate and environmental fund. The “debt-for-nature” swap is intended to ease the former Portuguese colony’s debt burden while allowing the country to conserve its ecosystems and prepare for future climate disasters. The island nation is particularly vulnerable to rising sea levels.

The USDA said it would put $490 million toward mitigating the risk of wildfires in 11 fire-prone landscapes across the American West. The funding will help the Forest Service lower the risk of explosive wildfires by thinning forests and conducting prescribed burns. The USDA also plans to invest in community programs to create wildfire protection plans and help residents make their homes more fireproof.
