This week in sustainability, the money and the rules went in opposite directions, and that's exactly why you need to see this breakdown.
Regulators eased off: the EU softened its carbon trading trajectory, California cut mandatory Scope 3 reporting categories from fifteen to five, and EFRAG proposed lighter CSRD rules for non-EU companies. At the same time, sustainable finance had one of its strongest weeks in years, from Deutsche Bank's €523 billion cumulative sustainable finance total to a $1 billion raise for Commonwealth Fusion.
We cover the full top 10, including Meta's exit from RE100 in the same week AI data centres passed $186 billion in green bonds, the building El Nino risk behind Europe's wildfires, and why the GHG Protocol and ISO are finally merging their carbon accounting standards into one.
We also count down the top three mind-blowing environmental facts of the week, and hand you one thing your business can act on right now.
If your organisation is trying to make sense of Scope 1, 2 and 3 reporting as the rules shift under you, this is the net zero and sustainability update built for business leaders, not just sustainability specialists.
Sustainability, net zero, carbon accounting and Scope 3 reporting all get simpler when you know what's actually moving. That's what we're here for every week.

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contributor to an organisation’s carbon footprint, yet many businesses are making decisions based on incomplete, outdated or estimated supplier data.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

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.
