Feeling like the lone voice on sustainability in your organisation? Sustainability Insights is where in-house sustainability professionals come together to swap ideas, tackle challenges, explore innovation and drive real sustainable change.
Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has.

Why join the Sustainability Insights Group?
Over the past 5 years hundreds of senior sustainability professionals have taken part, contributing to and benefiting from our monthly meetings.
Terrafiniti insights and solutions
For over 25 years we’ve supported and advised some of the world’s leading companies and not-for-profits. In each session we’ll share insights on best practice and the things organisations typically find challenging or get wrong.
Peer Collaboration
The meetings attract international sustainability specialists from diverse sectors. They provide a unique, safe, Chatham House Rule-based setting to engage with other sustainability professionals and learn from each other.
Personal and Professional Resilience
Members tell us that taking part in meetings provides supportive connections, builds motivation and reinforces resilience. The format of combining themed content plus discussion helps enhance sustainable business knowledge and navigate ever-changing sustainability challenges.
How does the Sustainability Insights group work?
Sessions are hosted by Joss and Dominic, Terrafiniti’s founding partners. Here’s how the group works …

A Featured Theme
Each session focuses on a featured sustainability theme and often focuses on topical issues. We use our knowledge, insights and experience to prime each session.

Group Discussion
Ask us difficult questions, engage with other senior sustainability professionals, share and explore challenges and opportunities. These are meetings, not webinars.

Trust & Share
We host small groups and follow the Chatham House Rule. While ideas are shared, personal identities are not and sessions aren’t recorded

Who
The meetings are for in-house sustainability professionals working in companies and charities – so if this is you, you’re welcome to join us!

Free to attend
The only cost is your time. We just ask that you make a constructive contribution (however small) and share your ideas and feedback.

When
Meetings are held online on the second Thursday of each month at 2pm (GMT/BST) and last for 1 hour. They are followed by an additional 30 mins Q&A where we can share learnings from our work with clients.

After materiality: turning findings into strategy
8 Oct 2026 | 2pm (BST) | 60 minutes + 30 minutes further Q&A
Materiality assessment tells you what matters. It does not tell you what to do about it, how far to go, or where to put your money. Moving from a prioritised list of material issues to a strategy which the organisation can act on, is where you can build real value and make the most of materiality.
For many organisations, once materiality assessment is completed, it is then mapped to disclosure requirements and included in reporting. However, it is often not used as a critical part of either reshaping existing strategy or driving a new one.
So, the question facing sustainability professionals is a practical one. How do you turn a list of material issues into genuine strategic focus – a coherent, defensible set of priorities, calibrated by your ambition, together with a deliverable plan that will be owned and resourced?
October’s session picks up where September’s materiality meeting left off. We will look at how to move from findings to focus, and how to make sure materiality shapes decisions, budgets and risk, not just your reporting.
In this session we will focus on the practical questions that matter most, including:
• How to prioritise – from issues you simply must manage to those where you can lead, differentiate and create value
• How to turn priorities into strategic pillars, goals and objectives, with resourcing dedicated to what is material and what is deliverable
• How to make it operational, connecting priorities to risk management, resource and capital allocation, and to the board
• Where it commonly goes wrong; actions that get missed or done badly, and what you need to get right.
This is an interactive working session, not a webinar/presentation. Come ready to compare thinking with peers, share the challenges you are navigating, and bring questions you have not yet resolved.
Members consistently cite the peer exchange in these sessions as one of their most valuable sources of practical insight, especially the chance to hear how others have translated materiality into strategy, ambition and resourcing in real organisational contexts.
Joss and Dominic will lead the session and stay online for a further 30 minutes to continue the discussion, explore specific situations and share what they have seen working (and not working!) across 25 years of supporting organisations through materiality and wider sustainability challenges.

What have we covered?
We've explored materiality and what that means for sustainability professionals and their businesses, engaging with people in different roles on sustainability and greenwashing in business + much, much more ...

Materiality Assessment - from complexity to clarity
September 2026
Materiality assessment is central to a complete approach to sustainability/ESG, it demonstrates that you have thoroughly analysed and prioritised the social and environmental issues that represent impacts, risks and opportunities for you and your stakeholders.
Like many things in sustainability, materiality can be a source of confusion and raises questions like ‘just how different is double materiality to what most of us may have been doing for years?

Setting Long-Term Targets for Sustainability
June 2026
Long-term targets sit at the heart of credible sustainability strategy. But right now, for many organisations, they are also a source of significant pressure. The evidence is stark. In March 2024, the Science Based Targets initiative removed 239 companies after they failed to validate their targets. Net Zero Tracker's 2025 Stocktake suggested that while almost two-thirds of the Forbes Global 2000 have net zero targets, nearly a third have no clear plan to deliver them. The gap between ambition and delivery is not primarily a problem of intent. It is a problem of how targets are set, structured and translated into plans that the organisation can execute.

Greenwashing – How to spot it and avoid the risks
May 2026
Greenwashing remains one of the most significant risks facing sustainability professionals right now. While regulators are taking increasingly tough stances, greenwashing remains common. A 2025 Which? study found that 62% of products still fail checks against the UK Competition and Markets Authority’s (CMA) Green Claims Code — and the CMA now has the power to fine companies up to 10% of global turnover through direct enforcement.

ESG Headwinds – Maintaining momentum in challenging times
April 2026
Corporate ESG and sustainability have faced growing headwinds across the UK, Europe and Asia. Political pushback, regulatory recalibration and more sceptical capital markets have contributed to softer public and investor sentiment. We explored these trends, and what they mean for sustainability professionals.

Preventing Greenwashing – what’s the role of sustainability professionals?
March 2026
This month, we explored what sustainability professionals could and should do to help drive out greenwashing - and the skills and competencies needed.

People in Sustainability
February 2026
As sustainability faces a range of challenges, it’s more important than ever to ensure buy-in, engagement and mobilisation of different people across your organisation.

Why Context is Critical for Strategy
January 2026
To succeed, companies need to understand their operating environment - the issues, trends and challenges that they need to navigate to deliver success. This means that context assessment should be the first step to effective strategy development.

Sustainability Management – what does good look like?
December 2025
What are the core elements of sustainability management, and how do they align to keep your efforts focused, embedded in your organisation, and primed to drive performance, transparency, and accountability?

Setting Sustainability Ambition
November 2025
Understanding and defining ambition is a crucial element of sustainability strategy and management. Sustainability Ambition relates to areas and aspects where the company has a degree of choice to decide what, where and how it acts.

Sustainability and Value Creation
October 2025
Recognising the full value of sustainability is now a strategic imperative. Missed opportunities can expose you to financial, legal, market, and reputational risks, but seizing them can enable innovation and future-proof your business.

Communicating Sustainability – navigating the challenges & building trust
September 2025
In this interactive session, we explored the complexities of sustainability and ESG communication and discussed how to build credibility and clarity.

Sustainable Transition - the fundamentals of good practice
June 2025
Extending the theme of sustainability strategy from our May meeting, in June we focused on the topic of sustainable transition – how organisations articulate, plan and undertake the journey from where they are now to where they need to be in the future.

Building Sustainability Strategy – the most important aspects for success
May 2025
If your organisation doesn’t have an up-to-date, relevant and integrated sustainability strategy then it can be open to multiple risks, but more importantly you might be missing out on valuable sustainability and business opportunities.

Reputation management – how to manage risk by association
April 2025
Reputation is widely regarded as one of the most valuable assets of an organisation – and sustainability can be an important contributor to both reputation and other dimensions of business value. In April’s meeting, we explored different dimensions of reputational risk, how it can be affected, and how you can protect it.
