This week I'm walking through the ten sustainability stories that mattered most, and honestly, the AI one at the top surprised me. We cover water scarcity hitting European supply chains, China's renewable hydrogen lead, the microreactor funding boom, why carbon footprints can mislead investors, tighter EU packaging rules for food and drink brands, heat now showing up in earnings calls, a rebound in sustainable finance, the US-EU row over sustainability reporting rules, and the fast-growing question of AI's own energy footprint. The story that tops the countdown this week: new research suggests AI-driven efficiency gains in fossil fuel extraction could add emissions equivalent to Mexico's entire annual output. If you work in net zero strategy, carbon accounting, or Scope 3 reporting, this is one to watch. I also share three mind-blowing sustainability facts from this week's news, including one about UK hospital buildings that genuinely stopped me in my tracks. Subscribe for weekly sustainability intelligence that actually moves the needle, and get in touch if you'd like to talk carbon strategy, net zero planning, or Scope 3 reporting for your business. Mentioned in this episode: Keep informed on Sustainability News I'm Will Richardson, Head of Ecosystems at 51toCarbonZero and a sustainability advisor with 25 years in the field. I founded Green Element in 2004 and spent two decades building it into one of Europe's most respected sustainability consultancies before it merged with 51toCarbonZero in November 2025. Climate action is both an obligation and an opportunity, and that's the thread running through everything I write here. I co-created Compare Your Footprint, carbon accounting software recognised as a key player in the Global Carbon Accounting Software Market, and I'm a Fellow of IEMA and a Chartered Environmentalist. Each week, I break down what's actually happening in sustainability: the data, the regulation, the greenwash worth calling out, and the practical steps businesses can take right now. No jargon, no doom-mongering, just clear thinking for people who need to make real decisions. I also host the Sustainability Solved podcast with Charlie Luxton, 200+ episodes and counting, where we talk to the people building the solutions. Based in Scotland. Writing for business leaders who want sustainability to make commercial sense, not just moral sense. My Personal Substack UPCOMING WEBINAR: The Scope 3 Blind Spot: What Your Supplier Data Isn't Telling You Scope 3 emissions are often the biggest contributor to an organisation’s carbon footprint, yet many businesses are making decisions based on incomplete, outdated or estimated supplier data. In this webinar, we’ll explore the biggest blind spots in supplier emissions data, why they matter for reporting and decarbonisation, and how leading organisations are moving beyond spreadsheets and assumptions to build a more accurate, scalable approach to Scope 3. LIVE ATTENDANCE BONUS: complimentary gap audit of your top 10 suppliers. Wednesday 16 September | 1pm BST https://www.51tocarbonzero.com/webinar-supply-chain/ September Webinar
