Sources and activities
Every declared source, with the activity data feeding it and the unit of measure it was reported in.
From operations to decisions
From raw data to climate decisions.
Nexta connects data, method, evidence and analysis to turn the inventory into a management tool.

ILLUSTRATIVE DATA · DEMO ENVIRONMENT
From operations to decisions
Data, method, evidence and analysis. The inventory becomes a management tool.
A calculator gives you the number. Climate management connects that number to evidence, analysis, priority and follow-up.
-
01
Connect
Takes in data from the different sources across the operation.
- Spreadsheets
- Systems
- Import
- Metering
-
02
Standardize
Applies a traceable methodology and emission factors.
- GHG Protocol
- Factor validity
- Units
-
03
Calculate
Calculates emissions by source, activity, unit, scope and category.
- Scope 1
- Scope 2
- Scope 3
-
04
Document
Keeps data, factor, calculation and evidence connected.
- Calculation record
- Attached evidence
- Version
-
05
Analyse
Identifies hotspots, trends and the largest emission sources.
- Hotspots
- Trends
- Comparison
-
06
Prioritize
Connects the results to reduction opportunities and levers.
- Levers
- Cost per tCO₂e
- Scenarios
-
07
Manage
Tracks inventory, indicators, targets and progress over time.
- Targets
- Annual series
- Reporting
Every number carries its source, the method applied and the document behind it.
A year later, when someone asks where that tonne came from, the answer is on the line itself, not in the memory of whoever did the work.
What becomes visible
An inventory that answers questions, instead of just closing a number.
The total can be analysed by scope, category, unit and period, staying connected to the data that makes it up. But the total is the last line of the work, not the only one: what supports a decision is what sits underneath it.
Factors
The factor used in each calculation, with its origin and validity period. What applied at closing stays on record. Recalculating later does not quietly rewrite a number that has already been reported.
Evidence
Invoice, meter reading, contract or manifest stay attached to the line they support, not in a parallel folder.
Quality and traceability
How much of the inventory has evidence, what is estimated and what still depends on reconciliation or review.
Hotspots
Where emissions concentrate and what changes in the result if that source is tackled first.
Targets and progress
The series over the years, the declared targets and the distance between the two.
The SBCE has already started. The obligation is phased.
Law 15.042/2024 created Brazil’s regulated carbon market. Companies operating relevant sources have time to map exposure, structure data and prepare monitoring.

Three ways to run the inventory
Start on your own. Ask for support when the operation calls for it.
The difference between the three is not how much platform you get. It is how much of the technical decision stays with you.

You start your Scope 1, 2 and 3 inventory with a guided journey, video lessons and step-by-step guidance inside the platform itself.

Specialist support
For when the decisions stop being about filling in fields and start being about method: inventory boundary, choice of factor, Scope 3 categories, preparing for third-party verification.

- Boundary decisions
- Scope 3 by category

ongoing
Operating at scale
Many units, large volumes and an inventory that has to close every year without starting from scratch, with import, review and continuous management.
- Multiple units
- Import and integrations
- Review before the number
- Comparable historical series
All three run the same inventory. Changing level does not restart the work.
Questions from people about to measure
What people usually ask before their first inventory.
Is the free inventory free consulting?
No, and the distinction is deliberate. The free tier gives you the guided journey, the video lessons and the step-by-step so that you can build your own inventory. When the operation calls for technical review or a decision about method, that is a separate service.
Where do the emission factors come from?
From recognized public references, each with its validity period declared. The factor that applied at closing is stored alongside the calculation, so a future factor update does not quietly rewrite a number that has already been reported.
Do I need Scope 3 to get started?
No. Scopes 1 and 2 already produce a usable inventory. Scope 3 comes in category by category, as the data exists, and the platform shows what is still outside the count instead of pretending the count is complete.
Can the inventory be used for third-party verification?
The platform organizes data, calculation records and evidence to support an external verification process. Verification, where applicable, is carried out by an independent third party, and its outcome depends on the scope contracted and on the quality of the data your operation was able to gather.
What if my data is scattered across spreadsheets?
That is the common case. The operation already produces the data; what is usually missing is the path between the data and the calculation. The import accepts the file as it exists today and shows what needs checking before it becomes a number.
Is the inventory I build mine?
It is yours, with the data, the method applied and the evidence attached. Exporting it does not depend on staying with us.
Do I need to know how to calculate emissions to use Nexta?
No. The platform guides the data entry and does the calculation from the activity data you provide. What still depends on your company is knowing your own operation and supplying the right data. When a methodological decision calls for technical judgement, you can bring in specialist support.
Can I correct a figure after it has been entered?
Yes. What matters is that the correction does not erase the inventory’s history. Changes must preserve the trail between data, factor, calculation and evidence, so that it is possible to understand what changed and to stand behind the number used at each closing.

Next step
The first inventory is what teaches you the rest of the agenda.
It shows which data your operation already has, which is missing and where the emissions that matter actually are.
Many units, large volumes or integrations? That is usually the case where the conversation comes before the screen.
