EPA plans to end greenhouse gas reporting program
The U.S. Environmental Protection Agency is preparing to discontinue its Greenhouse Gas Reporting Program, which has tracked emissions from major industrial facilities since 2010. This move aims to reduce regulatory burdens but raises concerns about losing critical data for climate policy. Environmental advocates warn it could hinder efforts to combat climate change.
New calculator shows flight emissions far exceed estimates
A new tool developed by researchers at the University of Surrey reveals that common carbon footprint calculators for flights significantly underestimate their climate impact. The Air Travel Passenger Dynamic Emissions Calculator, or ATP-DEC, indicates emissions can be several times higher than figures from tools like those from ICAO, IATA, Google and MyClimate. This finding highlights gaps in how aviation's environmental effects are measured.

Renewable energy sources, including solar and wind, have overtaken coal in global electricity generation for the first time on September 15, 2025. This shift is projected to slightly reduce CO2 emissions from the power sector. The International Energy Agency attributes this to rapid adoption of clean technologies.
Deadlines loom for updated Paris Agreement climate pledges
AI에 의해 보고됨
Countries worldwide must submit ambitious updates to their Nationally Determined Contributions (NDCs) under the Paris Agreement by early 2025, ahead of COP30 in Brazil. Developed nations face a year-end 2024 deadline, while developing countries have until February 2025. These pledges are crucial for aligning global efforts with the goal of limiting warming to 1.5 degrees Celsius.
