The construction industry contributes 37% of the world’s annual carbon dioxide emissions. Icelandic architect Arnhildur Plmadttir proposes using lava as a sustainable building material. She believes a single volcanic eruption could provide enough lava to lay the foundations of an entire city. Plmadttir has been researching this concept, called Lavaforming, for over five years. She and her colleague Arnar Skarphinsson have identified three potential techniques: drilling into magma pockets, channeling lava into pre-dug trenches, and 3D-printing bricks from molten lava. Iceland has 30 active volcanoes, and since 2021, eruptions have intensified on the Reykjanes Peninsula, with six eruptions in 2024 alone. These frequent eruptions provide opportunities for volcanologists to study lava behavior. Plmadttir’s concept relies on future advancements in forecasting lava flows, which currently requires complex simulations on supercomputers. The Icelandic Meteorological Office runs two simulations per eruption, improving accuracy with each event. Plmadttir and Skarphinsson are producing a speculative film set in 2150, showcasing a city built from lava, to be presented at the Venice Biennale in May.

Mar 19 Mount Etna continues to spew out Molten Lava along with millions of tonnes of natural Co2Please keep on imagining your electric car, heat pump & disposing of that log burner to reduce Co2 is saving the planet though.

Feb 16 Meanwhile in ItalyStunning footage of Mount Etna as it continues to spew out molten Lava.Millions more tonnes of Natural Co2 entering Earths atmosphere again – but please keep thinking being a vegan & ditching your log burner is saving the planet.

Apr 9 Decarbonising steel/cement production, better building design, reducing waste in construction, spatial planning & using lower-carbon materials can reduce cumulative embodied carbon from new construction between now & 2050 from 75 GtCO2 to ~30 GtCO2.

Apr 8 There’s another cost to using AI—an environmental one. Estimated #carbonEmissions of AI models are high, with Meta’s Llama 3.1 equating to the energy consumption of about 496 Americans in one year. (5/13)

Apr 11 3/ In the L-DAC component, ambient air is brought into contact with a sprayed alkaline solution.This reaction converts CO₂ into a carbonate solution that precipitates as solid carbonates—capturing roughly 1 Mt of CO₂ and delivering 1.48 Mt dry CO₂ annually.

Apr 12 May or may not know that concrete absorbs CO2 for decades.If used Locarb power to make it and captured the carbon released in the limestone roasting-> concrete just absorbs CO2 and more use, more takenSoviet style dedicated
