Services

Everything starts with an inventory you can defend.

Regulators, customers, and assurance providers all ask the same question: where did this number come from?

01 · Core service

Greenhouse gas inventories

All three scopes, or only what you need: Scope 1 and 2 for a California filing, or the Scope 3 categories a customer asked about.

Pick a scope to see what goes into it.

What it is

Direct emissions from sources you own or control.

What it covers

  • Natural gas and other fuels burned on site
  • Company vehicles and equipment
  • Refrigerant leaks
  • Process emissions

Data I'll ask for

  • Fuel and gas bills by site
  • Fleet fuel or mileage records
  • Refrigerant service logs

02

Inventory management plan

The written record behind the numbers: boundaries, data sources, methods, and emission factors. It makes next year's inventory repeatable, and it is the first document an assurance provider asks for.

03

Reduction strategy

The inventory shows where emissions come from. Then we rank what to do about them: easy levers first, then a roadmap. Includes support for SBTi targets and CDP responses.

04

Disclosure and assurance support

Scope 1 and 2 reports for California SB 253, answers to customer data requests, and help with your assurance provider's questions until they are closed.

05

Packaging EPR State laws

For producers covered by state packaging laws: packaging data for annual reports, fee estimates for budgeting, and tracking of which states and deadlines apply to you.

Approach

A first inventory takes about four months.

Half of that is gathering data. I start wherever you are, and you work with me directly throughout.

  1. 01

    Scope the work

    We set boundaries and decide which scopes and categories matter. You get a plain-language data request.

  2. 02

    Gather the data

    Your team collects the records. I explain what each one is for, check it as it arrives, and help fill gaps.

  3. 03

    Calculate and check

    I calculate emissions with documented methods and record every assumption and estimate.

  4. 04

    Explain and plan

    You get the numbers and what they mean: largest sources, easy levers, next steps. I stay on through assurance if you need it.

Timing depends on how quickly data comes together. Scope 1 and 2 alone can move faster; a first full Scope 3 inventory can take longer.

Standards and regulations

Built on the standards your reviewers use.

  • GHG Protocol Core

    Corporate Standard, Scope 2 Guidance, and Scope 3 Standard. The basis for every inventory.

  • California SB 253 Core

    Annual Scope 1 and 2 reporting for companies with more than $1 billion in revenue doing business in California. Scope 3 reporting is currently on hold in court.

  • Customer requests

    Supplier questionnaires and Scope 3 data requests from the companies you sell to, whatever your size.

  • CDP and SBTi

    Inventory data prepared for CDP questionnaires and science-based targets.

  • PCAF

    Financed emissions accounting for banks and investors. PCAF certified.

  • State packaging EPR

    Producer reporting and fees in the seven states with packaging laws: California, Colorado, Maine, Maryland, Minnesota, Oregon, and Washington.

About

One advisor, start to finish.

I'm Charlie. I spent several years as a carbon advisor at ENGIE Impact and Arcadia, working with more than 20 enterprise clients in apparel, resorts, restaurants, food, retail, and banking.

I led Scope 1, 2, and 3 inventories and advised senior leaders on California's climate disclosure laws. At West Elk, the person you talk to is the person doing the calculations.

I live in Paonia, Colorado, below Mount Lamborn and Landsend Peak, the two summits in the logo. Before consulting I worked in the Himalayas and northern Japan. Outside work I trail run, mountain bike, and backcountry ski.
