Alaya Consulting and Unwritten Join Forces in Hong Kong and China to Advance Climate Scenario Quantitative Analysis Across Asia
We announced a strategic partnership with Unwritten, an AI-powered climate risk platform, to deliver a value-added, decision-useful solution for climate scenario quantitative analysis across Asia. This “strong + strong” collaboration combines Alaya’s ESG and climate advisory expertise with Unwritten’s location-based quantitative modelling, helping organisations strengthen climate resilience, accelerate transition planning, and respond to evolving regulatory and investor expectations.
As climate-related risks become increasingly material, companies and investors face growing pressure to move beyond qualitative narratives toward credible, quantitative insights. At the same time, many organisations still face a common challenge: they are not sure where to start—what to scope, what to prioritise, how to quantify exposure, and how to translate scenario results into practical actions and disclosures.
Human Expertise Meets AI Analytics
By integrating human judgement and sector expertise with AI-enabled analytics, the partnership bridges the gap between disclosure and decision-making. The joint offering is designed to support clients in producing outputs that are auditable, repeatable, and management-ready, aligned with leading frameworks and market expectations, including ISSB/IFRS S2, TCFD, and NGFS scenarios.
“Climate risk is no longer just a reporting topic—it is a financial, operational, and strategic priority,” said Tony Wong, Founder of Alaya Consulting. “This partnership brings together the strengths of both teams to help clients move from not sure where to start to a clear, actionable roadmap—grounded in quantitative scenario analysis and built for real-world decisions.”
“Organisations increasingly need asset-level insight they can trust and use,” said Alex Spencer, Head of Sales at Unwritten. “By combining Unwritten’s location-based quantitative modelling with Alaya’s advisory expertise, we can help clients meet compliance and investor requirements while prioritising resilience business strategies”
What the Partnership Delivers
Through this collaboration, clients gain access to an integrated solution that combines strategic advisory with science-based modelling, including: asset-level climate risk quantification across geographies; scenario analysis under different climate pathways and time horizons (including NGFS-aligned scenarios); assessment of physical, transition, and nature-related risks; support for climate-related disclosure and reporting aligned to IFRS S2; and actionable insights to prioritise resilience and adaptation measures. The offering also includes practical implementation support such as scoping, materiality screening, data readiness, and decision-useful outputs.
The solution is especially relevant for asset-intensive sectors such as real estate, infrastructure, logistics, manufacturing, and investment portfolios.
Enabling Resilient, Transition-Ready Organisations
By integrating strategy with advanced modelling, Alaya Consulting and Unwritten help organisations move from climate awareness to action—enhancing transparency, strengthening resilience, and supporting better financial and strategic decision-making in an increasingly climate-driven environment.
