Hi, I'm
Thomas Mensah
I am the Founder of the DELIVERY CREDIBILITY INITIATIVE, a global effort to reframe climate performance around one uncomfortably simple idea: climate ambition means nothing without the institutional capacity to execute it.
When climate ambition outpaces an institution's capacity to deliver, execution risk emerges - the very real possibility that a transition plan collapses during implementation. This risk is material, systemic and still largely invisible to capital markets.
Weak institutional capacity doesn't just derail climate plans; it distorts investment decisions. Capital intended to drive impact ends up locked into organisations that struggle to deliver, while institutions with genuine delivery strength remain undervalued and overlooked.
I introduce the concept of the institutional capacity to execute into capital markets as a corrective lens - one that brings into focus whether an institution is truly equipped to translate ambition into outcomes. This capacity is the core signal of what I call delivery credibility: the real-world readiness to turn commitments into results.
Climate ambition means nothing without the INSTITUTIONAL CAPACITY to execute it.
THE GAP THE WORLD ISN'T SEEING
Climate action is often framed through science, policy and finance — all essential lenses, yet none built to answer a simple question:
"Can the institution actually deliver what it promises?"
That question sits in a blind spot of today’s climate dialogue.
This isn’t because anyone is neglectful; it’s because the climate conversation has evolved faster than our understanding of institutional design. The climate transition is, by its nature, an execution challenge — but we’ve never built the language, frameworks or shared understanding needed to evaluate execution capacity at scale.
The Delivery Credibility Initiative exists to illuminate this missing dimension: the institutional foundations that sit beneath every climate ambition.
THE INTERVENTION THE MARKET HAS BEEN WAITING FOR
The Initiative brings an execution practitioner’s perspective into a space that has rarely examined institutional readiness. I will be engaging widely — with institutional investors, asset managers, non-profit organisations, academics and industry practitioners — to elevate the concept of institutional capacity to execute as a new interpretive lens.
To refine this lens, in addition to speaking globally, I will also take on selective pre-investment due diligence work. These real-world assessments will surface the institutional patterns that consistently shape whether climate commitments survive implementation.
As the Initiative grows, I will be bringing together a small group of impact-driven institutional investors and asset managers who recognise the need for this shift. Together, through a dedicated invite-only forum, we will develop the world’s first market standard for capital markets to evaluate the institutional capacity of investee organisations to execute their climate commitments.
WHY DELIVERY CREDIBILITY MATTERS
0.5%
Fewer than 1% of companies have committed to align capital expenditure with their decarbonisation goals -
TPI Global Climate Transition Centre, State of the Corporate Transition Report (2025)
40%
Nearly 40% of firms have missed their publicly stated 2020 climate targets or suddenly stopped reporting progress altogether - Nature Climate Change Study (2025)
0.4%
In 2022, over 18,600 organisations disclosed climate transition plans to CDP. Only 0.4% met all 21 indicators that CDP defines at the hallmarks of a credible plan - Carbon Disclosure Project Report (2023)
16%
Only one in six (16%) of the world’s largest companies are currently on track to reach net zero emissions in their operations by 2050 - Accenture, Destination Net Zero Report (2024)
THE FUTURE OF SUSTAINABLE INVESTMENT depends on ambitious targets delivery credibility.
GET INVOLVED
INVITE ME TO SPEAK
I speak internationally about climate execution, delivery credibility, and the institutional design problems that quietly decide the success or failure of climate strategies. My talks combine practitioner insight with strategic clarity, helping audiences rethink climate performance through the lens of institutional capacity to execute.
If you’re convening investors, policymakers, sustainability leaders or industry practitioners, I can bring a perspective that is rarely heard.
DISCUSS COLLABORATION
If you’re exploring how to strengthen institutional readiness, assess the execution capacity of investee organisations, or integrate delivery credibility into your pre-investment due diligence and portfolio strategy, I’d welcome a conversation.
I work with institutional investors, asset managers, and mission-driven organisations seeking to understand whether their climate ambitions are supported by the institutional architecture required to deliver them.
