Conference Agenda

Welcoming Remarks & State of the Industry

A warm welcome from CAA co-founders with a mindfulness exercise and scene setting for the day. This will include a summary of some of the key challenges, insights and statistics on the state of the carbon accounting industry, following a 3-month research project led by the CAA.

Panel: Where Is Corporate Net Zero Heading?

Five years on from the SBTi Net Zero Standard, the consensus is converging and evolving to respond to the diverse and practical considerations that companies face in setting out towards their targets. The ISO Net Zero Standard, expected for draft consultation in 2026, represents international consensus on the definition of net zero for organisations, a definition aligned with the new SBTi Net Zero standard on target setting. These standards reflect significant and important improvements in the way we advise and support companies on their path to net zero.

At the same time, some challenges to independent consensus-based standards have emerged. New industry-backed advocacy groups like Carbon Measures are drawing both interest and backlash, and shining a light on product-based emissions accounting. Alongside this, a growing chorus of voices from academia, civil society and the private sector argues that corporate net zero standardisation must shift to recognise near-term action metrics alongside long-term emissions targets.

This panel brings together leading voices to explore the foundations: does organisational net zero still tally with country-level targets and the global carbon budget? How should the "net" be handled? Are the emerging standards converging on something coherent, or pulling in incompatible directions? And what does the next generation of net zero guidance need to get right?

Presentation & Q&A: In Conversation with the Standards

A candid conversation with the people behind the standards that underpin our work. An opportunity to hear directly from the GHG Protocol, SBTi and ISO about what is coming next and to put your questions to them.

Panel: Pragmatism Over Perfection, Making PCFs Work at Scale

Product Carbon Footprints are supposed to be driving decarbonisation. Instead, for many companies, they have become a bottleneck: tangled in methodological debates, often expensive and manual. This panel brings together a standards body, a technology provider, and a practitioner to ask: how do we close the gap between ambition and adoption?

Small Group Discussions

Delegates will be divided into small groups of up to 10 people to discuss key questions and challenges faced in the carbon accounting industry today. Topics include EACs, BVCM and removals, LCA at scale, emission factors, PCF harmonisation, scenario analyses and more. Delegates must select their topic ahead of the event.

PCF Clinic with Climatiq

A hands-on clinic for practitioners working through Product Carbon Footprint challenges. Bring your real-world PCF questions and work through them with support from Climatiq.

How Can We Professionalise Our Industry Whilst Achieving the Scale We Need?

Carbon accounting is at a crossroads. Investors, regulators and boards increasingly expect emissions data to meet the same rigour as financial data. The launch of the RCAA professional register is a landmark step. But professionalisation creates a tension: the industry needs to scale rapidly to meet demand, yet higher standards risk creating bottlenecks. This session explores how we navigate that tension and what it means practically for everyone in the room, whether you are an independent consultant, an in-house sustainability lead, or a service provider trying to hire.

How to Leverage AI in Carbon Accounting

AI is reshaping carbon accounting, but between the hype and the reality, what does it actually look like in practice? This session brings together a variety of voices to share real-world examples of how AI is being applied across emissions measurement, data quality, and reporting. Expect honest accounts of what is working, what is not, and where the technology genuinely accelerates progress versus where it introduces new risks around transparency and over-reliance on automated outputs.

How to Match the Accounting Method to the Decision You're Actually Making

Corporate GHG inventories answer one question: what emissions should we attribute to this organisation? But that is a different question from: will this decision actually reduce emissions in the real world? In this session, Matthew walks through his thinking comparing attributional corporate accounting, consequential life cycle assessment, and project/policy-level accounting, using case studies to show where the three methods give strikingly different answers.

The session will also cover the GHG Protocol's proposals for "multi-statement" disclosures, including the introduction of a consequential statement alongside the traditional attributional inventory. What does this mean in practice and how should practitioners prepare?

How to Establish an Internal Carbon Price and Construct Carbon Abatement Curves

An internal carbon price is one of the most powerful and underused tools sustainability leaders have for shifting how their organisations make decisions. But setting one that is credible, defensible, and actually influences behaviour is harder than it sounds. This session walks through the practicalities: how to arrive at a price that reflects your risk exposure and decarbonisation ambitions, how to build abatement curves that help you prioritise where to invest, and how to frame both in language that finance teams and boards will take seriously.

How Can We Make Carbon Data More Inspiring?

Calculating emissions is the easy part. Making the complex science accessible and inspiring change is much harder. This session gives practical examples of how we can bring carbon accounting data and insights to life to maximise their impact.

Delegate-Led Unconference

A highly interactive delegate-led session where both the topics and the format are decided by popular vote. Delegates pitch ideas (30-second pitches), then vote on what to explore. The audience also chooses how each topic is discussed, whether as a panel, fishbowl, small group discussion, debate, or another format entirely. All under Chatham House Rule. Maximum 50 delegates. This session will not be recorded.

A Delegate-Led Closing Plenary

Andrew and Emilien will facilitate a delegate-led conclusion of the day, covering outcomes for us as a carbon accounting community and hopes for the future of the industry. A highly interactive closing plenary session you do not want to miss.
