Why does this matter?

Compliance risk
You have a legal obligation to meet and could face penalties.
Assurance readiness
The underlying data and methodology increasingly need to withstand external scrutiny.
Customer requirements
The same emissions data increasingly supports customer and procurement requests.
HOW WE WORK

Send us what you have. We take it from there.

STEP 1

Discover & Intake

We define your legal entities and operational boundaries, map your applicable emissions sources, and gather the data: spreadsheets, utility bills, supplier records. We work with what you have readily available.

STEP 2

Calculate & Solve

We calculate your inventory to GHG Protocol standards, logging clear assumptions wherever data gaps remain, so every figure holds up later.

STEP 3

File & Disclose

We produce reporting-ready outputs aligned to CA SB 253, TCFD, and third-party assurance, with the methodology and evidence needed to stand up under review.
