Your US customer asked for carbon data. Here is what each request means.

Four requests Indian exporters get. Tap one to read it.

Send us your Scope 1 and Scope 2 for our Scope 3

A large US customer. California Senate Bill 253

What it means

California Senate Bill 253 (SB 253) makes big US companies report their emissions. That means companies set up under US law, with revenue above 1 billion US dollars (USD), that do business in California.

From 2027 they report Scope 3 too. Scope 3 is the emissions behind what they buy from you.

Scope 1 is the fuel you burn. Scope 2 is the electricity you buy.

Their own first Scope 1 and 2 reports carry a 10 November 2026 date. It is not your deadline. The law puts no duty or fine on you.

What to send

1. Scope 1 and Scope 2 for one full year, in tonnes of carbon dioxide (CO2) equivalent, written t CO2e, with each factor and its source.
2. Your output for the same year, so they can work out their share of your emissions.
3. The method: Greenhouse Gas Protocol (GHG Protocol). Scope 2 location-based (the grid factor where you use power), and market-based (your renewable certificates) if you hold any.
4. A note on what is estimated and what comes from bills.

The law lowers the pressure on your US customer to demand audited figures from you.

If you send nothing

They may fall back on estimates from what they spend with you.

Those make you look like an industry average, not like your plant.

Senseible reads your fuel invoices and electricity bills and traces each line to its document. It does not give the third-party assurance the US company needs for its own report.

Report your reductions for Project Gigaton

A US retailer. Walmart’s supplier programme

What it means

Walmart started Project Gigaton in 2017 to cut or avoid one billion tonnes of emissions in its supply chains by 2030.

You set goals in areas such as energy, packaging, waste and transportation. Then you report what each action saved.

It is a reduction report, not your full footprint.

Walmart said in February 2024 the goal was reached. It still collects supplier reports.

What to send

• A baseline year and the reporting year, for the same sites.
• Grid electricity in kilowatt hours (kWh) for each year, from bills. Convert bills in kilovolt-ampere hours (kVAh) to kWh.
• Renewable kWh: rooftop solar used on site, open access units, green tariff units.
• Efficiency projects: what changed, when, and the kWh or fuel saved, with before and after readings.
• Fuels by type and quantity.

Example, one garment unit 2,00,000 kWh solar used on site 2,00,000 x 0.675 = 1,35,000 kg, or 135 tonnes of carbon dioxide (CO2) avoided

Walmart’s tool may use another grid factor, so its figure can differ. Keep your own calculation.

You enter these in Walmart’s Sustainability Hub yourself. Keep the bills and meter readings behind every figure. Never claim a reduction you have not measured.

If you send nothing

Gigaton is Walmart’s programme, not a law.

Walmart’s guidance for the year sets the areas, questions and reporting window. Ask your buyer what happens if you skip a year.

Senseible supplies the monthly kWh and fuel figures from your bills, year on year, each tied to its source document. You enter them in the hub.

We need a plant-level environmental product declaration (EPD) for your steel

A US contractor. Buy Clean California

What it means

An environmental product declaration (EPD) states the carbon in one product, for one plant.

Buy Clean California covers structural steel, rebar, flat glass and mineral wool board insulation on contracts from state agencies, the University of California and California State University.

The winning contractor must submit an EPD for the plant that made the material. An industry-average EPD does not count.

A trader cannot use another mill’s EPD for the same grade.

What to send

1. Ask your importer if the project falls under the Act, and which product category applies.
2. Check the limit for that category with the California Department of General Services (DGS). Compare it with a realistic estimate for your plant.
3. Commission a facility-specific EPD, verified by an independent verifier.
4. Keep production and energy records for the EPD period. The verifier will sample them.

If you send nothing

Your steel cannot be used on that contract.

Same if the global warming potential (GWP) in your EPD is above the state limit, however good your price.

Senseible keeps your fuel and electricity invoices with their source documents. An EPD practitioner and verifier ask for plant data like this. A life cycle assessment (LCA) practitioner prepares the EPD itself.

Use eGRID (US power-grid database) factors for your electricity

A US customer’s form. A template habit, not a rule for India

What it means

eGRID is the US Environmental Protection Agency’s (EPA) database for electricity made in US grid regions. It has no figure for India.

Some supplier templates carry it as the default column. Usually the sender never meant it for an Indian factory.

What to send

Your electricity in kilowatt hours (kWh), with the Central Electricity Authority (CEA) factor: 0.675 kilograms of carbon dioxide (CO2) per kWh for financial year (FY) 2025-26, version 22.0.

The Greenhouse Gas Protocol asks for the factor of the grid where the power is used.

Write the factor and its source in the form, so they can see why it differs.

If you use their factor

A US region factor on Indian kWh describes neither your grid nor any real power plant.

Senseible reads the kWh from your electricity bills and applies the Central Electricity Authority (CEA) factor, naming the source on every line.

Your bills give you the energy and fuel figures all four buyers ask about.

Upload a bill and get your carbon number. Senseible then builds your buyer answer pack, a PDF and Excel file that answers the usual buyer questions, for the questions your bills can answer.
