I had the pleasure of working with Jackie Spiteri on the development of the Technical Screening Criteria (TSC) for Water Supply; Sewerage, Waste Management and Remediation Activities under ASEAN Taxonomy Version 4. Jackie played a pivotal role in managing this complex and technically demanding process from start to finish, demonstrating a rare combination of subject-matter insight, organisational skill, and interpersonal effectiveness.

From the outset, Jackie approached the work with remarkable efficiency. She quickly familiarised herself with the technical scope and requirements, structured the workflow clearly, and ensured that all milestones were met without compromising quality. Her responsiveness was a standout feature — she consistently addressed queries and feedback promptly, enabling the team to maintain momentum and avoid bottlenecks.

Jackie’s diligence was equally impressive. She not only ensured that the draft criteria were technically robust and aligned with the overarching Taxonomy framework, but also that they were practical and applicable in a diverse ASEAN context. She took the time to understand stakeholder perspectives, balance differing priorities, and incorporate constructive input into the work product.

What truly set Jackie apart, however, was her ability to manage the process in a way that inspired trust and respect from all involved. Her professionalism, calm approach under pressure, and commitment to collaborative problem-solving created an environment in which everyone could contribute effectively.

Thanks, Thomas! It was a privilege to work alongside you and the DNV team on the ASEAN Taxonomy Versions 3 and 4. The collaboration on the Technical Screening Criteria for Water Supply, Sewerage, Waste Management and Remediation and the Real Estate and Construction Sector Activities was both challenging and rewarding, and your expertise and partnership made the process a real success. We’re proud to have contributed to such important work and look forward to future opportunities to collaborate.
