Summary

Publicly listed prices for carbon accounting software in Southeast Asia fall into three bands: free Scope 1 and 2 tools, mid-market platforms at about USD 33,000 to 88,000 a year, and enterprise platforms at about USD 55,000 to 260,000+ a year.
Most vendors publish no prices. The figures here come from cloud marketplace listings and procurement data, checked in September 2026.
Your quote rises with legal entities, Scope 3 depth, land-sector emissions, assurance and implementation support.
Disclosure rules in Singapore, Malaysia, Thailand, Indonesia, the Philippines and Vietnam decide how much you need to measure, and when.
Singapore's Sustainability Reporting Grant and EDGE Grant, and Malaysia's ESG tax deduction, reduce the net cost.

Your CFO has asked a simple question: what will carbon accounting cost us? You open five vendor websites and find five "Book a demo" buttons. Meanwhile, your disclosure deadline under SGX, Bursa Malaysia or your local securities regulator is already on the calendar.

This guide gathers every publicly listed price we could verify in September 2026. It also sets out the regional rules that decide how much you need to measure, and the grants that reduce the bill.

How much does carbon accounting software cost?

Publicly listed prices fall into three bands:

Band	Annual price (USD)	What you get	Examples (publicly listed)
Free tools	0	Scope 1 and 2 calculators, single user or basic reporting	Persefoni Pro (1 user); Gprnt, backed by the Monetary Authority of Singapore (free Scope 1 and 2 for SMEs); Bursa Malaysia's Centralised Sustainability Intelligence platform (free for listed companies)
Mid-market platforms	~33,000 to 88,000	Scope 1 to 3, IFRS S2-aligned reporting, pricing tiered by company revenue	ClimateTracker on AWS Marketplace: USD 2,750 to 7,300 per month
Enterprise platforms	~55,000 to 260,000+	Scope 1 to 3, supplier data, audit support, integrations, priced by revenue band	Persefoni on AWS Marketplace: USD 55,000 (revenue under USD 250M) to USD 260,000 (under USD 25B)

Procurement data points to the same range. Vendr reports a median Watershed contract of about USD 70,000 a year, with contracts ranging from about USD 21,000 to 158,000.

Most vendors publish no prices at all. Greenly, Normative, Unravel Carbon, Net0, Sweep, SAP and Salesforce all ask you to contact sales. The figures above come from the few vendors that list on cloud marketplaces or share their contracts through procurement platforms.

What drives the price

Vendors that do publish pricing tie it to the size and complexity of your business. Persefoni and ClimateTracker set tiers by company revenue. IBM Envizi prices by the number of data accounts you connect. In practice, your quote rises with:

Number of legal entities and sites. Each entity needs its own data and emission factors.
Scope 3 depth. Screening Scope 3 with spend data costs far less than collecting activity data from hundreds of suppliers.
Land-sector emissions. Food, agriculture and forestry companies setting SBTi FLAG targets need farm- and mill-level calculations, which adds data collection and modelling work.
Assurance. Audit trails, auditor access and evidence exports for limited or reasonable assurance add scope and support hours.
Implementation and advisory. Onboarding, data mapping and methodology support are often quoted separately from the licence.

Which regional rules set your scope

The rule that applies to you decides whether you need a Scope 1 and 2 calculator or a full Scope 3 platform with assurance support.

Country	Who reports, and when	Scope 3	Assurance
Singapore	All SGX-listed companies report Scope 1 and 2 from FY2025. Large non-listed companies (revenue of S$1bn or more and assets of S$500m or more) from FY2030	Mandatory for Straits Times Index companies from FY2026; voluntary for other companies	Listed companies from FY2029
Malaysia	National Sustainability Reporting Framework: large Main Market companies from 2025, other Main Market companies from 2026, ACE Market and large non-listed companies from 2027	Can be deferred 2 to 3 years; business travel and employee commuting still required	Framework not yet final
Thailand	SEC rules aligned with IFRS S1 and S2: SET50 from FY2026, SET100 from FY2027	Scope 1 and 2 first	Verifiers registered with TGO or under international standards
Indonesia	PSPK 1 and 2 (aligned with IFRS S1 and S2) apply to periods from 1 January 2027. OJK's draft regulation phases companies in from FY2027 to FY2030	Under consultation	Under consultation
Philippines	SEC Memorandum Circular 16 of 2025: largest listed companies from FY2026, mid-size from FY2027, smaller listed and large non-listed companies from FY2028	Timing to be confirmed	Limited assurance on Scope 1 and 2, two years after first report
Vietnam	2,166 named facilities complete a GHG inventory every two years (Decision 13/2024; Decree 119/2025)	Facility-level inventory	Facility reporting to government

Hidden costs to budget for

The licence is one line of the budget. Companies across the region tell us about these costs:

Consultant fees on top of software. In our sales conversations, the most common current setup is a consultant plus spreadsheets. Two Indonesian manufacturers use an international consultancy for their emissions inventory. A Malaysian food and beverage company pays an external consultant for Scope 3 while tracking the rest in Excel.
Product footprints. One Singapore consumer brand received consultant quotes of 30,000 to 40,000 to footprint two products.
Rework when methods change. Companies starting with spend-based estimates often recalculate when their auditor or SBTi asks for activity data.
Switching costs. Companies replacing a legacy platform re-map their data and re-baseline their emissions.

Software, consultant or free tool: comparing total cost

Buyers in regional tenders now ask vendors for a like-for-like comparison covering the platform, implementation, advisory, support and total cost over three to five years. Use the same structure for your own comparison:

Free tools cover Scope 1 and 2 at no cost. They suit companies whose rules require Scope 1 and 2 only, such as most SGX-listed companies outside the STI until assurance starts in FY2029.
Consultant-led inventories carry a fee every reporting year, and your data stays in the consultant's files.
Software platforms carry an annual licence, and the calculation history, audit trail and supplier data stay with you year after year.

Grants that reduce the cost

Singapore

Sustainability Reporting Grant (SRG): covers up to 30% of qualifying costs, capped at S$150,000, including software, consultancy and assurance. It is open to Singapore-incorporated SGX-listed companies and non-listed companies with revenue of S$100m or more. STI companies are no longer eligible.
EDGE Grant: from 30 September 2026, it replaces the Productivity Solutions Grant and the Enterprise Development Grant. It covers up to 70% for SMEs and 50% for larger companies, capped at S$100,000 per company per year. Confirm with Enterprise Singapore whether your carbon accounting project qualifies.

Malaysia

ESG tax deduction: Bursa-listed companies can deduct up to RM50,000 a year of ESG reporting costs, including GHG tracking software, verification and consultants, for years of assessment 2024 to 2027.

In Indonesia, the Philippines and Vietnam, we found no government grant specific to carbon accounting software as of September 2026.
