💚🌊 The GreenWave Podcast By Synergy International 🌊💚 Episode 36 was out on Monday and you don't want to miss this one!

SBTi Raises Stakes with 2.0 Revisions

SYNI, your indefatigable hostess, focuses on the Science Based Targets initiative and its draft revision to the Corporate Net Zero Standard, which were recently updated. We hope you didn’t think we would go for a light and cheerful topic to close out the summer? No, no! Instead SYNI plunges into the deep end of sustainable governance and corporate regulation, taking a close look at STBi Version 2.0 and the fine line between pragmatic target setting and protecting long-term reductions that the net zero carbon emissions goal requires. So grab your notebook and sit at your desk for this one as we're working through complex policy and making recommendations how to best navigate the changes. Episode 36
Our posts from last week touched on some important topics:

Say It 5x Very Slowly: Scalable MetaSurface Supercool Cement



💚🌊 Say It 5x Very Slowly: Scalable MetaSurface Supercool Cement 🌊💚 When something has earned the title of being "supercool," we should all presumably want to know a lot more about it. True that such superlatives are thrown around much more liberally in today's society. But eventually, the test of actually being "supercool" will be played out in the public domain. So let's not take on claims of "supercoolness" lightly, lest we all face a "superuncool" climbdown that could end up on TikTok to haunt public conscious for years to come.

🔥 Within this overheated context, we were captivated by research published in ScienceAdvisor this week that detailed the latest innovations in supercool cement, especially given the fact that buildings contribute nearly 40% of global energy consumption and 36% of carbon emissions throughout their life cycle.

🧱 The work points to a quiet shift in how we specify envelopes. Researchers engineered cement that cools itself by design, using a metasurface that forms during hydration. Multiple sizes of ettringite crystals and a hierarchy of pores scatter sunlight, while the chemistry drives strong mid infrared emission into the open sky window. In plain terms, the material reflects most incoming heat and radiates the rest away, no plug or pump required. Read more...


Underground Energy Storage Shows Cost Efficiency Digs the Dirt



💚🌊 Underground Energy Storage Shows Cost Efficiency Digs the Dirt 🌊💚 The word "underground" has a somewhat ambiguous connotation, albeit rich in history and used throughout different eras to mean very different things. We're quite big fans of the word, siding with its post '60s Dylanesque cache of a lurking counter culture. We also have our experience of going "underground" when it came time to ace an important exam, where a singular focus defied any substrata surroundings.

🔋So what are we to make of ultra cheap energy storage that digs in the dirt to go "underground"? Safe to say innovation in energy storage will not look like a container full of batteries. Yet it could look like infrastructure built next to where energy is used. Think earthworks, heat, and pipes. The target is seasonal shifting that turns summer surplus into firm supply when the grid is hungry.

☀️ The practical path uses solar to charge heat into large earthen mounds held at high temperatures. Put the storage beside factories, power plants, or towns, and run fluid through embedded piping to deliver heat on demand. When electricity is required, make steam for existing turbines. Moving heat and power is costly, so co location wins. That includes storage temperatures in the 600 degree Celsius class. Read more...


Europe’s 2025 Sustainability Progress Is Clear in Eurostat’s Report



LinkedIn 💚 🌊 Europe’s 2025 Sustainability Progress Is Clear in Eurostat’s Report 🌊 💚 Who doesn't love a good old-fashioned annual statistical omnibus? And nobody does it better than Eurostat, who have produced another blockbuster featuring this year's key figures on Europe's people, economy, energy and the environment. Plenty of wise people say the numbers tell a story and the European sustainable story in 2025 is a mostly positive one.

⚡ Renewables are advancing. The EU reached 24.6 percent of gross final energy from renewables in 2023, with Sweden at 66.4 percent and Finland at 50.8 percent. Energy dependency stands at 58.3 percent, and supply has pivoted toward Norway and the United States after the fall in Russian flows. This underpins energy security and net zero, and resilience across the bloc.

🔌 Energy demand is easing and the mix is shifting. Final energy consumption fell 3.3 percent in 2023. Solid fuels dropped from 8.2 percent in 1993 to 2.2 percent in 2023, while renewables and biofuels rose from 4.8 to 12.6 percent. Petroleum products account for 37.4 percent, electricity 22.9 percent and natural gas 19.7 percent. At home, space heating takes 62.5 percent, water heating 15.1 percent and cooling remains small and is rising. Read more...
