CO₂ CALCULATOR

Reduce your CO₂ emissions

Calculate your current carbon emissions with our calculator: the tonnes of CO₂ your service travel produces today, how much of it remote assistance avoids, and the kilometers your technicians no longer have to travel.

The emission factors we use

Three numbers turn a trip into kilograms of CO₂. They are on screen, and every one of them is a field an editor can change.

Plane: 0.101 kg CO₂ per km

The calculator asks for the kilometers by plane of one trip and multiplies them by the trips each technician makes per year and by the technicians who travel. Nothing else about the flight is modelled: no cabin class, no stopovers, no airport transfers.

Car: 0.108 kg CO₂ per km

The factor is per vehicle and kilometer, so it does not go down when two technicians share a car: the calculator counts the kilometers of one trip once per traveling technician. If your team car-pools, the real figure is lower than what you see here.

Hotel: 40 kg CO₂ per night

A room-night factor, standing for the energy a hotel spends on one room for one night. The nights are counted per trip, so a two-night visit already carries 80 kg before anyone has moved a wheel.

How we calculate it

No black box: five numbers in, one formula, and every assumption written down.

What you type in. Five numbers about the trips your team makes today: the kilometers by plane and the kilometers by car of one trip, the hotel nights of one trip, the trips each technician makes per year, and how many technicians travel to give support. The kilometers are the one-way distance, exactly as the calculator this page replaces asked for them, and they are not doubled for the way back — so if your technicians come home, the real footprint is larger than the one on screen and the saving with it.

The formula. One trip emits kilometers by plane × 0.101 plus kilometers by car × 0.108 plus hotel nights × 40, in kilograms of CO₂. That figure is multiplied by the trips per year and by the number of technicians who travel, and shown in tonnes. Nothing is weighted, averaged or corrected afterwards: what you read is that multiplication.

What remote assistance changes. The calculator assumes 25 % of those trips are replaced with a remote video session — the same assumption as the ROI tab, so three out of four trips still happen. The avoided emissions are that quarter of the total, the kilometers shown are that quarter of the kilometers, and the «trees» figure divides the avoided kilograms by 22 kg, the CO₂ a mature tree absorbs in a year. Our customers replace between 25 % and 40 % of their trips on average, so 25 % is the cautious end of what we see.

What it does not include. The footprint of the remote session itself is not subtracted, so the avoided figure is a gross saving and not a net one. Neither the manufacture of the vehicles and the glasses, nor the spare parts you ship, nor the emissions of the machine while it waits for a technician are in the calculation. It is an estimate for a business case and an order of magnitude, not an audited greenhouse-gas inventory.

Frequently asked questions

Which trips should I count?

On-site interventions: repairs, breakdowns, inspections, commissioning, audits and acceptance tests — anything that puts a technician in front of a customer machine. Use the average trip, not the worst one: the point of the page is the order of magnitude of a year, and you can move every slider afterwards to see how sensitive the result is.

Where do the emission factors come from?

They are the factors the Wideum CO₂ calculator has used until now: 0.101 kg of CO₂ per kilometer by plane, 0.108 kg per kilometer by car and 40 kg per hotel night. They are averages, not a measurement of your fleet. If your sustainability team works with its own factors, each one of them is a field an editor can change on this page, and the result follows.

Are the kilometers one way or return?

One way. The calculator asks for the distance of the outbound journey of a single trip and does not double it, which is how the previous calculator worked and why the figure is on the cautious side. If you want the round trip in the result, enter the full distance there and back.

How do you turn tonnes of CO₂ into trees?

By dividing the avoided kilograms by 22, the CO₂ a mature tree absorbs in a year. It is there to make the tonnes imaginable, not to suggest that planting that many trees cancels the trips: a tree takes decades to reach the size where it absorbs that much.

Can I use this in my sustainability report?

Use it to build the case, not to file it. The result is an estimate from five averages, with the boundaries described above — no vehicle manufacture, no shipping, no measurement of your own fleet. A report needs your own boundaries, your own factors and your own data; this page tells you whether the saving is worth measuring properly.

Does it count the emissions of the video call?

No. A remote session needs a phone or a pair of smart glasses, a network and a video call, and none of that is subtracted from the avoided emissions. We prefer to say so rather than to add a number we have not measured: read the avoided tonnes as the travel you no longer make, before the cost of replacing it.
