Carbon Accounting Software for Scope 1–3

Stop reconciling spreadsheets. Start trusting your footprint.

Carbon inventories fail when activity data resides in silos across utilities, equipment, ERP exports, and regional teams. SINAI provides a system of record to consolidate activity data, apply GHG Protocol-aligned methodologies and emission factors, and produce a single audit-grade ledger you can defend.

"We had wanted to include all our business units in Scope 3 reporting for some time. What we were missing was time. Under the previous methodology, adding the four remaining units would have meant at least another month and a half of work. Now we intend for the next inventory cycles."

Daniel Azevedo

Environmental & Climate Change Analyst at Wilson Sons

"With SINAI, we’re able to have much more mature conversations about our climate journey—diving deeper into big projects while aligning with best-in-class practices for regulated solutions."

Terri Finn

Environmental Manager at Optimus Steel

“ With the SINAI’s software, our process has been deeply improved in the tracking, analysis, and decision making, since our emission inventory and results are available in detail and, accurately right after the data input. We are ready to move forward with the next steps in our neutralization journey. “

Rafael Oliveira Silva

Corporate EHS Specialist, Siemens Energy

"SINAI has been a key partner in managing the data for Minerva Foods' GHG Emissions Inventory, making reporting more efficient and ensuring complete transparency and traceability of information. We can clearly see our key indicators, which makes strategic decision-making more secure and well-founded."

Tamara Lopes

Minerva Foods, Sustainability Executive Manager

"SINAI has exceeded our expectations, delivering the expertise and resources to calculate the entirety of our scope 3 inventory efficiently. With SINAI, we no longer have limitations around only tracking scope 1 and 2 and business travel emissions which will enable us to amplify our focus on our firm’s decarbonization initiatives."

Rebecca Antonini

FSI, Head of Corporate Sustainability

"SINAI's modules can be used as the company evolves in the climate agenda, providing flexibility to parameters specific to the business."

João Davi

Wilson Sons, Head of Sustainability

"BRK started using SINAI at an important stage in our climate change strategy. In only two months, we were able to engage several teams on the climate change agenda. SINAI presents carbon pricing in a simple and objective way and this was key to engage the board."

Carlos Almiro de Magalhães Melo

BRK Ambiental, Head of Corporate Sustainability

"SINAI has been one of the most effective ways of bringing our organization together to improve the quality and reduce the time we spent on GHG inventories and data analysis compared to other tools we've tried. SINAI is invaluable for our robust decarbonization strategy and transition path to Net Zero."

Common questions about emissions measurement

What makes measurement audit-grade in SINAI?

SINAI Measure helps teams create traceable, assurance-ready emissions inventories by centralizing data, methodologies, calculations, and audit records in one platform. Instead of relying on disconnected spreadsheets, teams can manage Scope 1, Scope 2, and Scope 3 carbon accounting with clearer evidence trails, stronger controls, and more defensible outputs.

Do you support all Scope 3 categories?

Yes. SINAI Measure supports Scope 3 carbon accounting across relevant categories, helping companies calculate value chain emissions with greater consistency. Teams can combine supplier data, procurement data, emissions factors, and configurable methodologies to build a more complete greenhouse gas inventory and improve accuracy over time.

How does AI Emissions Match work?

AI Emissions Match helps turn messy operational, supplier, and procurement data into emissions calculation inputs faster. It can identify key fields, classify records, and match data to relevant emissions factors or methodologies, reducing manual cleanup while supporting more scalable GHG emissions measurement.

Can we configure organizational structures and units?

Yes. SINAI Measure supports complex enterprise structures, including facilities, business units, regions, and operational boundaries. This helps teams organize emissions data in a way that reflects how the company actually operates, making emissions inventory software more useful for reporting, analysis, and decision-making.

Can SINAI work with emissions data from different enterprise systems?

Yes. SINAI can work with emissions and activity data from different enterprise systems and partner platforms, depending on the company’s data setup and implementation needs.

Is SINAI pricing public?

SINAI pricing is not usually presented as a fixed public package because enterprise needs vary by company size, data complexity, modules, and implementation scope. The best next step is to request a demo so SINAI can understand the required carbon accounting, reporting, and decarbonization workflows.

How do you ensure outputs are defensible in assurance?

SINAI Measure supports defensible assurance outputs through centralized data, configurable methodologies, version history, audit-ready exports, and clearer calculation logic. This helps teams explain how emissions were measured, which data sources were used, and how results were prepared for internal review, reporting, or third-party assurance.
