Carbon & ESG reporting
from operations to disclosure

Stacksync pulls emissions and consumption from OSIsoft PI, SAP S/4HANA, and your meter data into your ESG platform on a daily cadence, two-way, with field-level lineage on every figure for audit.

Where ESG reporting breaks in production

Three reasons carbon numbers arrive late and unprovable.

Emissions reporting aggregates fuel, generation, and consumption data from operational systems that never agree on units or timing. Here is where the disclosure cracks.

01 - Annual scramble

Carbon data only moves once a year

Emissions sit in OSIsoft PI and SAP S/4HANA until disclosure season, then teams export it all at once. A daily cadence means the number is always current, not reconstructed under deadline.

LATENCY
02 - No lineage

You can't trace a reported figure

When an auditor questions a Scope 1 number, teams can't show which operational records produced it. Without field-level lineage, defending a disclosure means rebuilding it by hand.

COMPLIANCE
03 - Unit mismatch

Every source counts differently

Fuel volumes, generation in MWh, and consumption in different units arrive on different clocks. Aligning and converting them by hand introduces errors that surface only during the audit.

Replace many legacy vendors.

Every tool Stacksync replaces is one fewer vendor, one fewer bill, one fewer integration to maintain.

Securely connects to your systems with:

How often does emissions data refresh?

On a daily cadence by default, or more often where sources support it. Data from OSIsoft PI and SAP S/4HANA flows into your ESG platform continuously, so the disclosure number is always current.

Can we prove how a reported figure was calculated?

Yes. Every figure carries field-level lineage back to the operational records that produced it, so when an auditor asks about a Scope 1 number you can trace it to source.

How do you handle different units across sources?

Unit conversions and emission factors are applied in the mapping layer, so fuel volumes, MWh, and consumption align to one reporting basis without manual recalculation.

Which ESG platforms do you support?

Pre-built two-way connectors cover platforms like Watershed, Persefoni, Sphera, and Salesforce Net Zero Cloud, plus your warehouse, with the same lineage and replay across all of them.
