Sustainability Briefing — 27 August 2026
Europe's power system faced a summer of extremes, with heatwaves and drought straining supply even as solar output hit new records, while Brussels pushed forward electrification and ETS reforms to reshape energy costs and industry support. Elsewhere, standard-setters and regulators turned to measurement and materials, advancing web-specific carbon accounting and pointing to circularity as a source of both environmental gains and business opportunity.
Ember: heatwaves strained Europe's power supply, but record solar output cushioned daytime demand
Ember reports that successive June–July 2026 heatwaves pushed temperatures above 40°C across parts of Europe, raising cooling demand while disrupting nuclear, gas, coal and hydropower. Solar was the only major source to perform better than usual, running 17% higher on heatwave days in France and Hungary and supplying 25% of EU electricity in both June and July for the first time on record, though prices still spiked in the evenings when solar faded.
Ember: drought drove EU hydropower to a decade low, tightening supply and lifting prices
According to Ember, EU hydropower production fell to its lowest level in at least a decade for May, June and July 2026 after a dry Alpine winter, with seven of the EU's eight largest producers below their five-year averages in July. Combined with thermal-plant outages, this helped push day-ahead prices in Italy and Spain to their highest peaks since the 2022/23 gas crisis.
EU unveils Electrification Action Plan and ETS review, aiming to halve reliance on fossil imports
On 17 July 2026 the European Commission presented an Electrification Action Plan alongside a review of the EU Emissions Trading System, targeting an indicative rise in electricity's share of final energy use from 23% today to 46% by 2040. The Commission estimates reaching that level could cut the EU's fossil-fuel import bill by €260 billion per year, and a parallel proposal would let member states reduce network charges and ensure electricity is not taxed more heavily than gas.
EU ETS review would extend industry support and add new sectors
The Commission's ETS review proposes increasing free allocation to industry worth €6 billion for 2026–2030 and slowing the phase-out of free allowances for sectors under the Carbon Border Adjustment Mechanism until 2038. It also strengthens the system for aviation and maritime, extends it to waste incineration, and reforms the Market Stability Reserve to reduce price volatility.
Green software: GSF advances a web-specific version of the Software Carbon Intensity standard
The Green Software Foundation reports that in Q1 2026 its SCI for Web specification will define web-appropriate measurement boundaries across servers, networks, third parties and end-user devices, along with functional units and mandatory disclosure requirements so results are comparable and defensible. The design work flags that credits based on unverified 'green hosting' claims can let organisations improve scores without cutting actual energy use.
EEA: circular-economy shift offers the EU an environmental and economic 'win-win'
The European Environment Agency's three new circularity assessments find that stepping up a circular economy could deliver significant environmental benefits while opening a strategic economic opportunity through better access to materials and the creation of new businesses. The EEA stresses the need to accelerate investment in circularity to meet EU climate and environment targets.
