JMH Advisory helps institutions close the gap between reported sustainability and real outcomes, so the work holds up in front of stakeholders, investors, and time.
Frameworks applied, KPIs reported, SDGs mapped. The harder questions — what changed, for whom, and would it have happened anyway — are where credible work begins. That conviction shapes every practice below. The work begins with measurement: evidence for where sustainability genuinely matters, what it costs to ignore, and how it can be built to work in harmony with operations rather than against them, sharpening efficiency instead of adding overhead.
For organisations whose ESG position now affects cost of capital, procurement eligibility, and investor access. From materiality assessment to governance design and active rating management, these are positions built to withstand rating-agency and investor scrutiny.
Transition planning that moves from a net-zero commitment to an implementable roadmap with capital logic behind it. Scenario modelling, capex reallocation, and finance structuring built so the plan holds up under external stress-testing.
Climate risk integration for investment portfolios and lenders that asks what a green label actually depends on. Portfolio screening, due diligence, and LP-readiness built on explicit assumptions and aligned with emerging disclosure standards.
Scenario analysis and quantification of physical and transition risks aligned to TCFD and ISSB — for real estate, energy, and logistics operators in the GCC where climate exposure is material but rarely modelled.
For organisations still running sustainability, reporting, and operations on spreadsheets and inboxes. Process audit, agentic workflow design, and automation deployed where they create real leverage — with capability built in, not dependency created.
Every engagement is built to withstand the questions that follow it — from stakeholders, investors, boards, and time. The work spans financial services, energy and marine, aviation, construction and engineering, manufacturing, and impact investing, across the GCC, Southeast Asia, and beyond.
Institutions operating at the intersection of regional mandates and international capital standards face a credibility problem: sustainability infrastructure needs to satisfy global investor scrutiny without losing sight of what the business actually does. This engagement built that infrastructure from the ground up — materiality assessment through to governance design and inaugural reporting — leaving the client with a fully documented, independently coherent ESG position across 78% of its balance sheet. A fully documented, independently coherent ESG position, credible to global investors while staying anchored to the institution's regional mandate.
When ESG ratings start affecting cost of capital, clients demand sustainability data as a procurement condition, and investors expect more than a policy statement, the gap between where a business stands and where it needs to be becomes expensive. This engagement closed that gap end to end: a full gap analysis, direct stakeholder engagement across multiple business units, and a unified ESG strategy with clear initiatives mapped to the relevance of each unit, which in turn lifted the group's rating standing to MSCI AA.
This engagement was delivered for the ground handling company, but the strategy was built to integrate into the wider airport ecosystem, mapping where bottlenecks, roadblocks, and risks sit at the seams between operators, and how to navigate them where external enablers and partners hold the levers. Without a measurement architecture, strategy has nothing to stand on; this built the full system, then translated it into a roadmap calibrated to how the business actually operates.
Organisations under increasing supply chain ESG pressure — receiving data requests from clients integrating supplier criteria, and scrutiny from investors expecting more than a policy document — often find their existing sustainability posture is more gesture than substance. This engagement replaced that with something real: a multi-site materiality assessment across 13 topics, a roadmap of 36 executable initiatives, updated group policies, and structured training to ensure the team can own their ESG position going forward.
Deploying impact-first capital credibly requires more than intent — it requires a differentiated thesis, rigorous sector analysis, and a clear view of where the fund can win in a crowded landscape. This engagement provided that foundation: a comprehensive mapping of the global catalytic capital landscape, market sizing across five priority sectors including technology readiness and policy environment, and a facilitated process that translated research into a coherent investment thesis ready for investor communication and pipeline development.
Over five years of research at the frontier of materials innovation: developing smart and functional materials capable of harvesting energy, responding to environmental stimuli, and converting physical inputs into measurable outputs. The work spans characterization, computational modelling, rapid prototyping, and real-world application, and is published in the field's foremost scientific journals, including the Journal of the American Chemical Society, PNAS, and Chemical Society Reviews.
That depth of technical rigour is the foundation of how JMH Advisory works.
Jad Mahmoud Halabi · Founder, JMH Advisory
I came to this work from an unusual direction. I spent five years as a doctoral researcher in materials science, building and stress-testing models, and that training left me with one instinct above all others: the ability to tell a real result from an artefact of methodology. When I look at a thesis, a strategy, or an impact claim, I want to know what assumptions it depends on, what the counterfactual looks like, and where the framework might be flattering the outcome.
I carry that instinct into sustainability and climate work because the field needs it. Much of what passes for ESG and impact today is output-counting: frameworks applied, KPIs reported, SDGs mapped. The harder questions — whether anything actually changed, for whom, and whether it would have happened anyway — are too often left underexamined. That gap, between what gets measured and what truly matters, is where I believe the most important work sits.
So this firm begins with measurement and evidence: showing where sustainability genuinely matters to a business, what it costs to ignore, and how it can be built to work in harmony with operations rather than against them. Done well, this is no compliance burden. It sharpens efficiency, clarifies risk, and earns the credibility that mobilises capital. Increasingly, it also means bringing better instruments to the work — including AI — to keep performance honest year-round instead of reconstructed once for a report.
I've been fortunate to work across financial institutions, energy, aviation, manufacturing, and impact investing, with deep experience in the GCC and Southeast Asia and an outlook that isn't bound to either. Across all of it, my conviction holds: rigour and imagination are not opposites. The discipline to measure precisely is what makes it possible to deploy boldly. That is the work I want to do, and the standard I want JMH Advisory to be known for.
