A national Swiss campaign has run every PFAS method in the Commission's guidelines side by side, and none of them can name most of the organic fluorine in wastewater.
Europe is about to make wastewater monitoring for antimicrobial resistance routine, while researchers warn that the numbers it produces can't yet say how many people are affected or what risk they face.
A clause buried in a gas tariff order makes oxygen a design parameter for Spanish biomethane plants, and shows how differently Europe handles a problem it hasn't yet agreed on.
The Czech agriculture ministry can list pipelines, ponds and hectares after nine years of drought spending, but in the worst groundwater summer in decades it cannot yet show what they changed.
The Commission wants network tariffs to reward whoever can shift load away from the peak, and that makes pumping stations and aeration basins, which rarely feature in the debate, part of the argument.
The Commission's proposed Climate Resilience Law would give every member state the same warming path to plan against, put water security in every national plan and set deadlines that collide with the next river basin cycle.
Researchers in China have used a global model to work out where solar-driven interfacial evaporation could supply drinking water, and how much – a promising result in which the assumptions matter as much as the headline.
The International Energy Agency has reviewed 134 policies and regulations for fitting data centres into power systems, and its clearest lesson is that a flexible connection is faster than waiting for firm capacity.
Calculations by the DVGW research centre in Karlsruhe show that if small biogas plants reach the gas grid through a shared upgrading unit and injection point, investment falls by up to 55% and the biomethane injected rises by 16% compared with connecting plants one by one.
The World Meteorological Organization reports that river flows in 2025 were among the lowest in 35 years, with Central and Eastern Europe among the hardest-hit regions as groundwater declines year after year.
