OCEANS™ CALCULATE EMISSIONS
Turn business activity into traceable emissions calculations
Calculate Scope 1, 2, and 3 greenhouse-gas emissions while keeping activity data, emission factors, assumptions, and supporting evidence connected to every result.
Understand not only your emissions total—but how it was calculated.
- Activity data
- Unit conversion
- Emission factor
- Formula
- Result
- Evidence
- Assumptions
- Review
A carbon total is only useful when you can explain it
Carbon accounting involves more than applying a factor to a spreadsheet value. Teams must determine boundaries, categorize activities, select appropriate emission factors, manage estimates, and preserve a consistent calculation history. When this work is spread across spreadsheets, calculations become difficult to review, repeat, and communicate. OCEANS™ Sustainability brings the process into one structured and transparent workflow.
Hidden calculation logic
Stakeholders cannot easily understand how a reported value was actually produced.
Inconsistent emission factors
Different teams may use different sources, versions, units, and assumptions.
Difficult Scope 3 calculations
Value-chain data is often incomplete, estimated, or distributed across suppliers.
Limited repeatability
Spreadsheet calculations are difficult to reproduce consistently in the next reporting period.
Scope 1, 2 and 3
Build a complete view of emissions across your business
Scope 1
Direct emissions
Emissions from sources owned or controlled by your organization.
- Stationary fuel combustion
- Company-owned vehicles
- Refrigerant leakage
- Process emissions
Scope 2
Purchased energy
Emissions associated with purchased electricity, steam, heating, and cooling.
- Purchased electricity
- Purchased steam
- Purchased heating
- Purchased cooling
Scope 3
Value-chain emissions
Relevant emissions occurring across your upstream and downstream value chain.
- Purchased goods and services
- Capital goods
- Fuel- and energy-related activities
- Transportation and distribution
- Waste generated in operations
- Business travel
- Employee commuting
How it works
A structured process from source data to reported result
- 01
Define boundaries
Configure the entities, facilities, reporting periods, and emissions sources included in your inventory.
- 02
Classify activities
Associate operational records with the relevant emissions scope, category, and calculation method.
- 03
Select emission factors
Apply documented emission factors based on activity type, geography, reporting period, and available data.
- 04
Calculate emissions
Convert energy, fuel, distance, spend, mass, and other activity information into greenhouse-gas emissions.
- 05
Review results
Identify unusual values, missing information, estimates, and calculations that need additional evidence.
- 06
Approve and report
Finalize reviewed results for dashboards, internal analysis, and stakeholder reporting.
See what is behind every number
OCEANS™ Sustainability keeps each emissions result connected to the information used to produce it. For every calculation, your team can retain:
- Original activity data
- Source document
- Reporting period
- Organizational entity
- Emissions scope and category
- Applied emission factor
- Unit conversions
- Calculation method
- Estimates and assumptions
- Review status
- Calculation history
When a result changes, your team can understand what changed and why.
Trace the source
Follow a result back to the record and document it came from.
Review the method
See the formula, unit conversion, and factor applied to produce it.
Understand the change
Compare versions to see what changed between reporting periods, and why.
Emission-factor management
Use documented factors—not unexplained numbers
The quality of an emissions calculation depends on the relevance and transparency of the emission factors behind it. OCEANS™ Sustainability is built to keep the source, geography, unit, reporting period, and version of every factor visible alongside the calculations that use it.
- Factor source and publication year
- Geography and applicable activity
- Unit of measure
- Reporting period the factor applies to
- Factor version, preserved as versions change
- Approval status for custom or supplier-specific factors
Move from spend estimates toward better Scope 3 data
Scope 3 accounting often begins with limited information. OCEANS™ Sustainability helps you start with available data, document the calculation method, and improve accuracy as better activity or supplier-specific data becomes available—without presenting estimates as perfect measurements.
- 1
Spend-based estimate
Emissions estimated from spend using industry-average factors.
- 2
Average activity data
Activity metrics such as weight or distance from external benchmarks.
- 3
Supplier activity data
Actual activity data provided directly by suppliers for your purchases.
- 4
Supplier-specific emissions data
Emissions calculated by a supplier using their own data and methods.
Make uncertainty visible—and preserve what changed
Not every organization begins with complete primary data. OCEANS™ Sustainability helps teams document estimates, assumptions, exclusions, and data gaps alongside their calculations, distinguishing between:
- Measured activity data
- Calculated values
- Supplier-provided information
- Spend-based estimates
- Extrapolated values
- Missing or excluded information
The objective is not to hide uncertainty. It is to understand it and improve the underlying data over time. Organizational structures, activity data, and methodologies can change between reporting periods — keeping a record of what changed and why helps your team maintain a consistent process as the inventory evolves.
Move from calculating emissions to understanding them
Once calculations are complete, explore your emissions inventory across the dimensions that matter to your business:
- Scope and category
- Entity and business unit
- Facility and geography
- Supplier or purchasing category
- Activity type
- Reporting period
- Data source or calculation method
Identify hotspots
Understand which activities contribute most to your footprint.
Monitor change
Compare emissions across reporting periods.
Prioritize improvements
Focus data-quality effort on the categories that carry the most weight.
Support reporting
Reuse reviewed calculations across stakeholder requirements.
Methodology
Built around recognized carbon-accounting concepts
OCEANS™ Sustainability structures emissions data and calculations around established greenhouse-gas accounting concepts, including organizational boundaries, emissions scopes, activity data, emission factors, and documented calculation methods. Our methodology explains:
- How organizational boundaries are established
- How emissions sources are categorized
- How calculation methods are selected
- How emission factors are managed
- How estimates and exclusions are documented
- How calculation changes are preserved
Carbon accounting software—with practical guidance
Selecting boundaries, identifying relevant emissions sources, and choosing calculation methods can be challenging for lean teams. OCEANS™ Sustainability combines software with guided implementation to help your team establish a practical calculation process using the information currently available.
