Trucks and heavy equipment are among the largest direct emission sources for many Indian companies in logistics, mining, construction and manufacturing. As BRSR assurance expands, those figures must be accurate and backed by evidence. Suppliers are also getting data requests from listed customers. Fleet emissions come mostly from fuel, which most companies already record. This guide explains how to calculate and report them, and how teams use HVI fuel and idle records as their data source.
BRSR Fleet Emissions Reporting: Guide for Indian Companies
Measure fleet and heavy equipment emissions from fuel and runtime data, prepare evidence for assurance and set targets that actually reduce emissions.
Who Needs Fleet Emissions Data
Requirements have changed several times. Check the latest SEBI circulars and take advice from your sustainability or assurance team.
| Who | Current position | What it means for fleet data |
|---|---|---|
| Top 1,000 listed companies | Must file BRSR, including emissions disclosures | Fleet fuel feeds Scope 1 figures |
| BRSR Core reporters | Assessment or assurance reaches the top 1,000 for FY 2026-27 | Fleet figures need evidence an assurer can check |
| Top 250 listed companies | Value chain ESG disclosures on a voluntary basis | May ask key suppliers for emissions data |
| Suppliers and contractors | Not always directly covered | Can expect data requests from listed customers |
How to Calculate Fleet Emissions
The fuel-based method is the simplest and most reliable. Multiply the fuel used by an emission factor for that fuel.
Use the emission factors your reporting framework or assurance provider specifies. Where fuel records are missing for a machine, estimate from runtime hours multiplied by typical fuel use per hour, and document the method.
Data to Collect for Every Vehicle and Machine
Good reporting starts with good records, kept all year rather than gathered at year end.
Turn Fuel Records Into Reporting-Ready Data
HVI records fuel, hour meters, odometers and idle time for every vehicle and machine, by site, building the audit trail your emissions figures need.
Making Figures Ready for Assurance
Assurers look for figures they can trace back to source records. These steps make that easier.
One source
Keep fuel and asset data in one system.
Reconcile
Match fuel issued to invoices every month.
Fill gaps openly
Document any estimates and how they were made.
Keep the trail
Retain records so every figure can be traced.
Ways to Reduce Fleet Emissions
Most reductions also cut fuel cost, so emissions targets and savings work together.
Cut idling
Idle engines burn fuel with no work done.
Maintain well
Clean filters, correct tyre pressure and healthy injectors.
Plan routes and loads
Fewer empty trips and shorter routes.
Train drivers
Smooth driving lowers fuel use.
Switch fuels
Electric, CNG or LNG where they suit the work.
Fleet Emissions by Site in HVI
A sample annual view, calculated from recorded diesel at 2.68 kg CO2 per litre.
| Site | Assets | Diesel used | Emissions | Data status |
|---|---|---|---|---|
| Mine site A | 42 | 2,40,000 litres | 643 t CO2 | Fully recorded |
| Logistics depot B | 65 | 1,80,000 litres | 482 t CO2 | Fully recorded |
| Project site C | 18 | 80,000 litres | 214 t CO2 | Some estimates used |
BRSR Fleet Emissions FAQs
Are fleet emissions part of Scope 1?
Yes. Fuel burned in vehicles and equipment you own or control counts as Scope 1. Emissions from hired transporters and contractors usually fall under Scope 3, and electricity for charging or depots under Scope 2.
How do I calculate diesel emissions?
Multiply litres of diesel used by an emission factor, commonly around 2.7 kg of CO2 per litre. Use the factor your reporting framework or assurance provider specifies, and keep the fuel records behind the total.
Does BRSR Core need assurance of fleet data?
BRSR Core assessment or assurance is being phased in and reaches the top 1,000 listed companies for FY 2026-27. Emissions figures, including those from fleets, need to be traceable to records an assurer can check.
I am a supplier. Do I need emissions data?
You may not be required to file BRSR yourself, but listed customers may ask for your emissions data for their value chain disclosures. Teams that record fuel in HVI can answer these requests quickly.
What is the easiest way to cut fleet emissions?
Reducing idling, keeping vehicles well maintained and training drivers usually give quick results, because they cut fuel use directly. Book a demo to see fuel and idle tracking in HVI.
Accurate Emissions Reporting Starts With Fuel Data
Record fuel, hours and idle time for every vehicle and machine in HVI, calculate emissions with a clear audit trail and track the savings from every reduction step.
