Regulations Are Raising the Bar—Is the Sustainability Talent Pool Ready?
📅 17 September 2026 • Annexion Partners
Regulation can create hiring demand faster than the job market can keep up, and that gap doesn't close on its own just because time passes. Singapore's Mandatory Energy Improvement regime has been in force for a year now, and it still asks for a specific professional that many buildings need but can't easily find.
A specific role, not just a broad skill.
Singapore's Mandatory Energy Improvement rule has required owners of large, energy-using buildings to appoint a mechanical engineer or energy auditor registered with the Building and Construction Authority since it came into force on 30 September 2025. This expert must carry out an energy audit and create a plan to cut the building's energy use by at least 10% compared to before the audit, with fines of up to S$150,000 for buildings that don't comply [1][2].
This is not just a general skill in sustainability. Owners can't simply hire someone with broad climate or ESG knowledge. They need someone officially registered by BCA for this job, which means the pool of qualified people is much smaller than the overall sustainability job market.
When a rule names a specific credential, it also points to which jobs are hardest to fill.
The talent pipeline is still catching up.
BCA has been preparing for this for years. As part of its industry plan, Singapore's building sector set a goal of training 25,000 professionals in green building [3]. They knew early on that there wouldn't be enough qualified people to meet the demand, and a year into the MEI regime, the numbers show exactly how wide that gap still is: BCA's own published list of registered Energy Auditors, the credential most directly built for this rule, names just 74 individuals nationwide, as of its most recent update on 9 September 2026 [4]. Building owners can also engage a mechanical engineer registered with the Professional Engineers Board instead, so this isn't the whole eligible pool, but it's a striking number against a regime that applies to every energy-intensive building 5,000 m² or larger, across offices, hotels, retail, hospitals, schools, and more, nationwide.
The demand side of this equation was built years in advance. The question now is whether the supply side has caught up.
How this will shape hiring across the region
Singapore shows the clearest example of this challenge: regulations require certain registered experts before enough people are trained to meet the need. Other countries in the region may face the same issue as they create their own green building rules. For companies hiring in Building Sustainability, this means that people with, or working toward, BCA registration are in a much smaller and more valuable group than the general sustainability job market.
