Flawed economic models mean climate crisis could crash global economy, experts warn States and financial bodies using modelling that ignores shocks from extreme weather and climate tipping points

We really must rethink what we mean by economic growth - it also has to be sustainable, and so must also encompass metrics beyond the financial.

Water Summit | February 11th 2026 in London Economist Impact's Water Summit in London in February 2026. Over 300 industrial water users, utilities and investors convene for water security and resilience.

Looking forward to attending the 1st @economist.com Water Summit: "Making water a boardroom priority", in London on 11th Feb.

We must advance sustainable water management to reduce business risk and drive innovation in water-related data, tools and strategies.

How England’s outdated water tracking system leaves regulators in the dark Experts warn accurately monitoring consumption by bulk users such as farmers, datacentres and businesses can be all but impossible

We need robust, integrated measurement of water use & wastewater generation across catchments & nationwide.

Without it, we cannot improve efficiency, expand recycling and reuse, or secure long‑term water resilience.

We need Government incentives to drive this.

UK to rejoin EU’s Erasmus student exchange programme Exclusive: British students will be able to participate in EU-wide scheme from January 2027, sources say

Well finally.... a long overdue return to the Erasmus programme.

Some really excellent news for UK students wishing to study in Europe, and for European students wishing to study in the UK. The potential for broadening the scheme is also a great move.

Do you think your MP is aware of the full implications of the climate crisis, across health, national security, food security and our economy?

Tell UK Leaders: Ban Bottom Trawling in Marine Protected Areas The UK government has finally announced a plan to ban destructive bottom trawling in 41 offshore MPAs. The catch? It’s not a done deal. A public consultation is open NOW before anything is finalised —...

Bottom trawling is one of the most destructive fishing methods in the world.

Please consider joining the campaign to have it banned, most particularly in Marine Protection Areas.

Data centres to be expanded across UK as concerns mount The number of data centres is set to jump by a fifth in the coming years, figures seen by the BBC suggest.

If new data centres add 71 TWh of energy demand, that means an increase in water demand of ~135 billion litres per year.

Adopting circular economy strategies for water management should be the enabler.

See you there!

Researchers from Bath’s Water Innovation and Research Consortium (WIRC@Bath) will lead the first large-scale demonstration of a technology to create ultra-pure water from wastewater after winning major funding from UK water regulator Ofwat.

www.bath.ac.uk/announcement...

#Research #Water

Delighted to be working with Northumbrian Water, Waterwhelm, AtkinsRéalis, SSE Thermal & others to deliver high purity water from treated final effluent using waste heat. The recovered water will be reused in industry, thereby reducing fresh water demand & demonstrating a circular economy approach.

Very bohemian..

The purchase cost of these wasted Easter eggs will be just over £40 million.

Do you think we need to re-evaluate what we are doing?

Happy Easter to all who celebrate.

The carbon footprint of this waste is about 14,720 tonnes of CO2, which is equivalent to someone driving their petrol car for 3,200 years.

8,000 tonnes of waste plastic, card and foil will come from the packaging around these wasted Easter eggs.

The UK will waste 8 million chocolate eggs this Easter, which is about 10% of what is purchased over the counter.

This has a water footprint of about 38.4 billion litres, equivalent to roughly 15,360 Olympic swimming pools worth of water.

Who should pay for urban wastewater treatment? The pharmaceutical and cosmetics industries have gone to the EU's court to challenge a directive that requires them to finance at least 80% of urban wastewater treatment. #EuropeNews

About 80% of micropollutants come from pharmaceutical or cosmetic use, so why should the manufacturers of such products not pay towards wastewater treatment?

Just 9.5% of plastic made in 2022 used recycled material, study shows Global research reveals most of 400m tonnes produced using fossil fuels, predominantly coal or oil

"Plastics recycling" is essentially a con.

Instead we are choking the planet (and our own bodies) with #PlasticWaste and #PlasticPollution
