United StatesIn the US the ask can come from an enterprise customer, an investor or lender, or California's climate laws, and the federal rules keep shifting. Whether you are answering a request, meeting a reporting duty, or just want a first carbon number, we help you turn it into an answer you can defend, without having to become a sustainability expert.

Shifting federal rules
An enterprise customer, an investor or lender, or a platform like CDP or EcoVadis wants your emissions data. Send us the wording and we prepare an answer you can stand behind.
See request support for A customer, investor, or platform asked youIf California's laws reach your company, or a customer keeps you reporting each year, we build the numbers, the records, and a process you can repeat. We check what applies to you first.

Open the US calculator for You want your own numbers firstSee GHG calculations for You want your own numbers firstFederal climate rules are in flux while California's laws and your own customers and investors keep asking for emissions data. The practical move is to keep credible Scope 1, 2, and 3 numbers ready, so you can answer whoever asks next.
In May 2026 the SEC proposed withdrawing its 2024 climate disclosure rules (SEC proposal). Federal reporting is still a moving target, so don't build your answer around a settled federal rule.
California's SB 253 requires emissions reporting for covered companies. On 24 June 2026, CARB announced that it intends to move the first Scope 1 and Scope 2 deadline from 10 August to 10 November 2026; that change still needs to complete the rulemaking process. SB 261 remains subject to a court order, and CARB says reporting is voluntary while that order applies. Even if you're not directly covered, customers and investors may still ask you for the data.
Procurement scorecards, CDP and EcoVadis requests, RFPs, lender checks, and vendor onboarding can all ask for emissions data, whatever the law says about you directly.
In the US, requests most often arrive through enterprise procurement, technology customer programs, CDP, EcoVadis, and investor checks. Keslio is independent and not affiliated with any of the companies named here.
Microsoft suppliers
We help with total-company emissions, service-level numbers, evidence packs, and consultant letters where the request calls for them.
Salesforce suppliers
We help you read the contract language and scorecard, and prepare the emissions data, EcoVadis evidence, and target questions it raises.
CDP and EcoVadis
We organize the emissions numbers, policies, records, and improvement actions these platforms ask for, request after request.
A SaaS company may need cloud and travel numbers, while a logistics company may need fuel, fleet, and customer allocation data. Where you start depends on your sector.
Sector
Enterprise sales, vendor onboarding, cloud assumptions, and customer-specific emissions data often drive the first request.
Sector
Supplier teams need one response file that connects emissions, policies, evidence, and who refreshes it each year.
Sector
Lenders, investors, partners, and customers often ask for your operating emissions and how you govern climate.
Sector
Retailers and marketplaces can ask for packaging, sourcing, product claims, and your company footprint.
Often yes. Customers, investors, lenders, platforms, and California-linked requests can still need your Scope 1, 2, and 3 data even when federal rules are unsettled.
Yes. We read the request, calculate emissions where needed, organize the evidence, and prepare your response for CDP, EcoVadis, or a customer's own portal.
Yes. We also help US companies build an emissions baseline, set a strategy, and stand up a reporting process they can repeat, so you are not starting from zero each year.
If a deadline or portal wording is already in front of you, send us the request. If you just want a first number, start with the US calculator.
Share the request, the deadline, or the question. We'll suggest the right first step.
