How much CO₂ does replacing a diesel generator save? Numbers for your sustainability report

The arithmetic for diesel displacement — 2.68 kg CO₂ per litre — with worked examples for a shop, a cold store, a mill and a hotel, ready for a sustainability report.

Buyers, lenders and hotel brands now ask for an emissions number. Diesel displacement gives you one you can defend: every litre not burned avoids about 2.68 kg of CO₂. Here are worked examples.

Key facts

  • Diesel: about 2.68 kg CO₂ per litre burned.
  • A 10 MT frozen store on diesel (300–500 L/day) avoids 290–490 tonnes of CO₂ a year on solar.
  • A mill burning 1,000 L/day avoids about 980 tonnes a year.
  • Frontières Bay's Phase 1 targets 5,000–15,000 tonnes avoided per year across 10–15 sites.

The formula

Litres of diesel avoided per year × 2.68 kg = kg CO₂ avoided. Divide by 1,000 for tonnes. If a gas backup runs a few days a year, subtract its emissions (roughly 40% less per kWh than diesel) — it will be small.

Worked examples

  • Shop with a small petrol generator, 1 L/day: ~1 tonne a year
  • Hotel, 300 L/day: ~290 tonnes a year
  • 10 MT frozen store, 400 L/day: ~390 tonnes a year
  • Feed mill, 1,000 L/day: ~980 tonnes a year

Putting it in the report

State the baseline (litres per year before), the method (2.68 kg/L), the measured result (litres after, from purchase records or the monitoring dashboard), and the avoided tonnes. Our monthly reports give service-contract customers the measured figure automatically.

Frequently asked

Is 2.68 kg/L the right factor?

It is the widely used combustion factor for diesel; some frameworks add upstream emissions, which raises it slightly.

Do you provide the report?

Service-contract customers receive a monthly energy and cold chain report including diesel avoided and CO₂.
