š Lakes are one of the most vital natural resources on our planet. 27 August 2025 is the first-ever World Lake Day, dedicated to tracking and protecting the health of millions of lakes around the globe.ā£
ā£
š§ Protecting lakes is crucial as they contain about 90% of the worldās surface freshwater supply, making them critical sources of readily accessible water.ā£

This Copernicus #Sentinel2 image from 13 August shows Lake Suchitlan, šøš» El Salvadorās largest wetland reservoir and a key source of the countryās hydropower.ā£
ā£
In the #ImageOfTheDay, the green colouring on the lakeās surface points to the proliferation of aquatic vegetation. ā£
ā£
Such blooms are often driven by excess nutrients, pollution, and seasonal rainfall. Their presence can impact the lake's ecosystem by disrupting the habitat and well-being of the many species which rely on it.ā£

š°ļø The #CopernicusEU Sentinel satellites are monitoring the health of water bodies around the world. Furthermore, the Copernicus Marine Service delivers value-added information to support decision-makers in developing effective policies for addressing the consequences of invasive species.
Waste management and resource recovery remain essential to circular progress. The Department for Energy Security and Net Zeroās recent review identified strong potential for circular construction strategies and endāofālife reuse in construction to deliver quantifiable carbon savings. Yet challenges persist in the rollout of Simpler Recycling due to legacy property structures. Strengthening these backāend systems ensures green building products reāenter value chains, supporting both circular economy objectives and sustainable urban development. The collective impact across policy, design, education, and technology confirms that the carbon footprint of construction can be reduced dramatically when the sector treats sustainability as an integrated, measurable discipline rather than an optional ambition.
