Study Finds Wastewater Emissions Significantly Underreported Globally
A Princeton-led study published in Nature Climate Change reveals that national inventories vastly underestimate greenhouse‑gas emissions from wastewater systems. Across 38 countries, methane and nitrous‑oxide outputs are under‑reported by 19 % to 27 %, translating to a missing 94 million‑150 million metric tons of CO₂‑equivalent each year. The shortfall arises from outdated accounting methods and the exclusion of untreated sewage, decentralized networks, and latrines. Researchers argue that correcting these gaps is essential for accurate climate policy and utility‑level mitigation strategies.
