Data centres are about to get a sustainability label, and most businesses have no idea which ones they rely on. That's where this week's countdown lands, and it's the second week running they've taken the top spot. I've spent more than 25 years in sustainability, and I've rarely seen energy dominate a week the way it did during Climate Week NYC. In this video I count down the ten stories that mattered most for net zero strategy, carbon accounting and Scope 3 emissions, ranked by how often they appeared across the newsletters I read. We cover the EU's proposed mandatory labels for data centres, the COP31 push for 35% electrification by 2035 and the IEA's new special report, RE100's warning that there isn't enough clean power to buy, ISO's net zero standard failing its vote, a shrinking carbon removal market, nature disclosures doubling, food supply chains and regenerative agriculture, the final revised ESRS, Germany's 2045 fossil fuel exit and Bain's finding that 85% of consumers are worried again. Stay to the end for three facts, including one about farmland the size of Germany. Something personal to share too. From 28 September, Sustainability Solved goes weekly, after eight years of monthly episodes. One of the first guest-host series is with Dr Sophie Taysom on climate risk, property and insurance, which ties straight into this week's data centre insurance story.

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.
