The opening

Why this idea is overlooked

It feels non-commercial, like activism instead of business, but reporting mandates are turning ESG into required, well-paid compliance work.

The roadmap

1
Specialize in one framework
Pick the disclosure regime your target clients are being squeezed by: CDP questionnaires, EcoVadis ratings, CSRD for EU-exposed suppliers, or California's SB 253. 'ESG consultant' is vague; 'I get suppliers through EcoVadis' sells.
2
Get the technical credentials
Complete GHG Protocol training and a GRI or similar certification so you can defend your numbers. Carbon accounting is the hard skill this niche pays for.
3
Target squeezed mid-market suppliers
Your best clients are $10M to $200M companies whose biggest customer just demanded emissions data. They have real urgency and no in-house sustainability team.
4
Lead with a carbon baseline offer
Sell a fixed-fee Scope 1 and 2 footprint baseline as the entry project. It is scoped, deliverable in weeks, and naturally leads to reduction planning and reporting work.
5
Pick a software sidekick
Partner with a carbon accounting platform so data collection is repeatable instead of a spreadsheet swamp. Some platforms pay partner referral fees on top.
6
Convert projects into annual retainers
Disclosures recur every year and frameworks keep tightening, so structure engagements as annual reporting retainers. One anchor client's supply chain can feed you referrals for years.
