How to choose the right ESG consultant in Singapore
You need to carefully think about your organization’s needs and situation before choosing the right ESG consultant. To begin, please assess the current maturity level of your ESG. Do you need basic help with your first report or more advanced advice on climate scenario analysis and planning for the transition? Second, think about industry-specific knowledge. Consultants who have worked in your field will have a better understanding of your specific risks and opportunities. Third, check how well the consultant knows Singapore’s regulatory timeline, including the ISSB alignment that all listed issuers must follow and the new assurance requirements that are coming up. Fourth, look at the team’s technical skills and ability to handle complicated data analysis, especially when it comes to figuring out how much greenhouse gas they are responsible for and how much money it will cost. Lastly, think about how the consultant builds capacity. Do they merely provide reports, or do they actively support your internal team in managing sustainability for the long term?
There are many ESG consulting firms in Singapore that can help businesses at every stage of their journey toward sustainability. KPMG offers strategic thought leadership and technology-based solutions for climate risk, while Deloitte combines a global presence with strong government partnerships to help small and medium-sized businesses.

Frequently asked questions
1. What services do ESG consultants in Singapore typically offer?
In Singapore, ESG consultants usually help with things like sustainability reporting and disclosure, climate risk and carbon management, greenhouse gas accounting, creating a governance framework, setting up ESG data systems, giving advice on sustainable finance and preparing for assurance. A lot of them also offer training for board members and help with communication with stakeholders.
2. How much do ESG consulting services usually cost in Singapore?
The cost of hiring a consultant depends a lot on the size of the company, the scope of the work, the complexity of the operations and the consultant’s level of expertise. Fees can be based on the project, like preparing a sustainability report, or they can be based on a retainer for ongoing strategic advice. Companies can look into government help, like Enterprise Singapore’s ESG Ready Program, which pays for 70% of the costs of eligible activities for qualifying businesses.
3. How do I know if an ESG consultant is reliable?
Reliable ESG consultants demonstrate recognized qualifications (such as GRI Certified Sustainability Professionals or CFA Institute Sustainable Investing credentials), relevant industry experience, clear methodologies aligned with international standards and transparent client references. Membership in professional bodies, ISO certifications and partnerships with regulators or reputable organizations also indicate credibility.
4. Are ESG consultants in Singapore suitable for small and medium enterprises?
Yes, several consultants work with small and medium-sized businesses (SMEs) through smaller projects and government-funded programs. In partnership with Deloitte, the ESG Ready Program provides basic training and carbon assessments at a reduced cost. This makes ESG consulting available to smaller businesses.
5. What should I prepare before engaging an ESG consultant?
Before hiring a consultant, make sure you know exactly what your regulatory responsibilities are based on your listing status and industry. You should also have a list of all the sustainability data you have, know who the key internal stakeholders are, have a rough budget and have specific goals, such as compliance, access to green financing, or strategic positioning.
6. How long does it usually take to complete an ESG reporting project?
Timelines are based on how easy it is to get data, how complicated the organization is and how wide-ranging the reporting is. It usually takes three to six months for a first-time sustainability report to go from gap analysis to publication. However, organizations with established data systems may be able to do annual updates in two to three months. Climate risk assessments and scenario analysis necessitate an extended lead time.
