Overview

• A new study by Colorado State University suggests transitioning to green wastewater treatment could save the U.S. $15.6 billion and reduce emissions by nearly 30 million tonnes over 40 years.
• Nature-based solutions such as wetland construction and reforestation could replace traditional grey-water systems, offering both economic and environmental benefits.
• Carbon markets could provide financial incentives for adopting sustainable water treatment methods, potentially generating $679 million annually.
• Researchers emphasize the dual local and global impact of integrating water and air quality measures through market mechanisms.
• The study's findings support further research and development of carbon credit methodologies to enhance water quality and sustainability.
