🚨 NEW | Wales accounts for HALF of all modelled UK abandoned mine methane emissions, yet official government data shows ZERO active methane capture projects.

The UK has 16 known operational sites. Wales has none 🧵1/4

@Point_of_Gold @ember_energy The 89% refers to the share of global CMM emissions left unreported, not the share of countries. Because the 50 non-reporting countries include China, India, Indonesia and the US, the emissions gap is much larger than the country count gap.

⚡ NEW: Super excited to share my first Ember report, and Ember's first Global Coal Mine Methane Review! 🌍

All the data is freely accessible via Ember's Coal Mine Methane Data Tracker 📊https://t.co/QOPehHTPUd

🤝 Huge thanks to everyone who contributed to this work!

NEW | Global coal mine methane emissions have NOT FALLEN since 2021, despite rising coal production.

Only 23 of 73 countries reported #CMM emissions, leaving 89% UNREPORTED.

Yet, existing tech could cut #CMM by MORE THAN HALF.

To provide context, every country also receives a confidence score reflecting the reliability of its emissions reporting and its potential for satellite monitoring.

Steady reductions in U.S coal production means the U.S is reducing its coal mine methane emissions, and is on track with the 30% reduction target as proposed by the Global Methane Pledge.

[Bex Horner (@bexhorner.bsky.social) @bexhorner]

The data tracker lets you explore each country's officially reported data to the UNFCCC. Where official data is missing, gaps are filled using EIA production estimates combined with UNFCCC emissions intensity.

NEW DATA TOOL | Coal mines are a major source of methane. The big culprits could be vastly underreporting their CMM emission.

Ember’s new data tool allows you to explore where official data is lacking: https://t.co/oNQSZreEbz

@ae_lunar @zhangxin_dawn Hi! The poster is available at https://t.co/ijYwxCoATH.

Feel free to contact me via DM or email if you have any questions.

At #EGU24? Come along to my poster at X5.93 between 10.45-12.30 to here me talk about global vertical profiles of tropospheric NO2 and O3 and how we can use these to improve the paramerisation of lightning in chemical transport models! ☁️⚡️👩🏻‍💻

[Karn Vohra, PhD @kohra_thefog]

We'll be talking about deriving NOx emissions for cities and hotspots in Asia (Eloise) and Africa (Nana) and vertical profiles of global tropospheric NO2 and ozone from TROPOMI (Bex @bexhorner ) ...

In 1995 Paul Crutzen, Mario Molina and Sherwood Rowland were awarded the #NobelPrize in Chemistry for helping us understand why the ozone layer was disappearing.

#OTD in 1987, nations signed the Montreal Protocol to help us protect it.
