Greenly Impact Summit 2026

Scope 3 is where 70% of your emissions sit. It's also where most companies are still relying on spend-based estimates that won't hold up to CSRD assurance, supplier audits, or the next round of investor scrutiny.

​AI is reshaping how this work gets done — but the conversation is full of noise. This session cuts through it.

​This is a working session — not another panel — built for the people actually doing the work: heads of sustainability, climate leads, procurement leaders, and the CFOs starting to ask harder questions.

​Over the evening, we'll cover the three things you can't afford to get wrong on Scope 3 in 2026:

​📡 Supplier data — getting it without burning the relationship. Engagement playbooks, questionnaire design, and how AI is closing the gap between spend-based estimates and supplier-grade data.

​🤖 AI in carbon accounting — what it does, what it fakes, what it can't. An honest look at where machine learning, LLMs, and automated emission factor matching create real precision — and where they paper over the gaps.

​⚙️ From hotspot to action — 90-day reduction roadmaps. Walk through how Greenly clients turn a Scope 3 inventory into a defensible reduction plan, with a live demo on real data.

​You'll leave with templates, a peer network of practitioners at your maturity level, and a clearer view of what to do on Monday morning.

​🥂 8PM onwards Curated drinks and dinner-style canapés. Attendees are pre-introduced based on sector and Scope 3 maturity, so you spend the evening with the right people.
