he net zero rulebook just got rewritten. The Science Based Targets initiative has released Corporate Net-Zero Standard 2.0, and in the same week a super El Niño officially emerged in the Pacific.

In this week's sustainability news countdown I cover the ten stories that matter most for business leaders and sustainability professionals: the new SBTi net zero standard and its five-year milestones, El Niño food price risk, the AI data centre energy crunch, extreme heat as an economic constraint, UK and EU reporting changes, and what investors are now demanding from the seafood sector.

I also owe you an apology. For a few weeks in May, the tool I use to gather news was reading my own newsletter back in as a source, which made some stories look bigger than they really were. In this video I explain what happened, what was still genuinely news, and how it has been fixed. There is a fuller write-up on my Substack: https://willsussolved.substack.com

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contributor to an organisation’s carbon footprint, yet many businesses are making decisions based on incomplete, outdated or estimated supplier data.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/

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.
