There will be no #GlobalPlasticsTreaty from #INC5.2. The Chair informed us at just after 6am this morning that, despite best efforts and a new revised Chair's text overnight, consensus could not be reached.

It is 5.30am in Geneva and the final #INC5.2 plenary is scheduled to resume.
The new revised Chair's text is many steps from being able to fully end plastic pollution, but it is a few steps in the right direction. Now we find out how countries will react.

Les Aubes - a series of free concerts every morning during summer from 6-7am on Bains des Pâquis. Completely free and the best bit is you can watch whilst enjoying your morning swim!

I escaped from the madness of #INC5.2 and Geneva with a day trip across the border to the Chamonix valley today. The (literal) high point of my walk was Lac de la Perseverance (photo 3), which seems a very suitably named lake to visit right now!

Some reflections on the first few days of #INC5.2 negotations in Geneva, towards a #GlobalPlasticsTreaty.
Are the negotiations going well? Frankly, not really, though there are reasons for hope 👇

Insightful screening of Homo Plasticus: Plastic Inside Us this evening, followed by an equally as insightful panel discussion. Lots of emerging evidence of the real health risks plastics pose to society, underpinning the need for a strong #GlobalPlasticsTreaty

Panel discussion on "science and research for an effective instrument": strong support for science-based decisions free of conflicts of interest, and a need for transparency in not just Treaty processes, but the data needed to support it.

Exposure modelling is a crucial part of assessing the risk from chemicals. Come and find out about the latest advances in exposure modelling at our #SETACVienna session on Wednesday! 0930 and 1140 in Hall D3, with posters up all day (172-194).

I'm fairly confident that I have never caught a DB train that wasn't delayed, and I've caught quite a few. Today is no exception! Though I suppose if they're *all* delayed, then at least you're more likely to still catch your connection...

#SETACVienna here I come! I'm taking a #FlightFree journey starting with the @eurostarnews.bsky.social to Brussels, then DB trains to Frankfurt and Vienna. Departure: 0704. Arrival: 2305 (if I make the connections!) Plenty of time to write that presentation! 😬

We studied a range of polymers - PP, LDPE, PA-6, HIPS and TPU - and quantified the release of water-soluble organics, as well as secondary micro- and nanoplastics (including their particle size distributions).

It's time for the return journey! After a weekend in the Tyrol Alps, I'm travelling back from Innsbruck via Zürich and Paris. Looking forward to some great views along the way!

Made the connection with *lots* of time to spare, mostly because the Frankfurt-Vienna ICE is 30 mins delayed. Not too bad, all things considered - at least I've avoided an unintended overnight stop in Frankfurt!

It's looking good for my connection in Frankfurt! 😌 And in fairness to DB, whilst their reliability might be rubbish, they do have a lovely app that keeps you informed how rubbish their reliability currently is!

20 min connection in Brussels? No problem! The "short cut" was open (first time I've seen that in years - @seatsixtyone.bsky.social take note!) and so I was on the correct platform 3 minutes after arriving.

Made my first connection to the @eurostarnews.bsky.social London-Brussels service with plenty of time to spare. A record 23 minutes from disembarking at Euston to the Eurostar departures lounge! I only have 20 minutes to connect in Brussels - let's see how that goes...

Today I will be travelling from Lancaster via Brussels and Frankfurt, and on the way back via Zürich and Paris. Making the most of an excellent value @interraileu.bsky.social ticket means the whole journey costs around £300 door-to-door. You'd struggle to fly for that!

Early start to catch the train to Vienna* for an ETERNAL #GreenPharma meeting. If I make all of my connections (that's a big if!) I will be there before 11pm. A long day, but much more relaxed than flying.
*Actually, Tulln, which is somewhere near Vienna

A reminder from a holiday up in the north west Highlands last week that #plasticpollution is pervasive - even the most remote of Scottish beaches suffer.

Snowy pre-work runs are the best! (Except for all the waist-deep wading.)
