illuminem summarizes for you the essential news of the day. Read the full piece on ESG News or enjoy below:

🗞️ Driving the news: Microsoft is adopting cross-laminated timber (CLT) to replace steel and concrete in its datacenter construction, aiming to lower the embodied carbon footprint of its facilities
The switch to wood materials could reduce the carbon impact of these datacenters by 35% compared to steel and 65% compared to concrete

🔭 The context: Steel and concrete production are major global carbon emitters, accounting for roughly 15% of greenhouse gas emissions worldwide
As Microsoft scales its datacenter footprint, emissions have spiked, with Scope 3 emissions rising by over 30% since 2020 due to construction and material use

🌍 Why it matters for the planet: By transitioning to CLT, Microsoft is leading an industry shift toward sustainable building materials, which could reduce emissions in construction and foster innovation in low-carbon infrastructure
This move aligns with Microsoft's goal to achieve carbon negativity by 2030 and reduce its Scope 3 emissions significantly

⏭️ What's next: Microsoft plans to incorporate low-carbon requirements into its supplier contracts and continues to invest in sustainable building technologies through its Climate Innovation Fund
These efforts could accelerate broader adoption of low-emission materials in the tech industry

💬 One quote: “We have to be system thinkers across the entire value chain of these materials that go into our datacenters,” - Jim Hanna, Microsoft’s sustainability lead for datacenter engineering

📈 One stat: CLT can reduce embodied carbon in datacenter construction by 35% versus steel and 65% versus precast concrete
