The True Carbon Cost of Training

The True Carbon Cost of Training

When we consider the cost of a training session, mostly we think of the financial side; hotels, trains/car hire, venue rental, catering etc. But there is another cost of Face-to-Face (F2F) events that is rarely measured. 

Despite how much media attention the climate crisis is receiving, we continue to make journeys to training events that are completely avoidable. Despite the huge rise in virtual events over the past 2 years; many organisations are now slipping back into the mentality of default F2F meetings, training, and conferences. 

But are these organisations aware of the true cost of this choice?

Here at VTT, we worked with a client who was interested in saving money on their training. They realised they weren’t tracking the cost of travel for the workshop participants; often these costs were absorbed into personal or local cost codes, so there was no way of knowing exactly how much of the budget was going into travel and hotels when it was related to Learning and Development (L&D). 

They were mainly interested in the financial cost to the business and had not fully considered the carbon costs to the environment. So, they asked us to conduct a thorough analysis on their behalf.

F2F Training: Impact Analysis

First, some background details:

The F2F workshop was on the topic of “Time Management” and was set to last 3 hours. It was due to be delivered in Peterborough, a city in the centre of the UK. It was scheduled for a Monday morning, which by its nature, incurred extra cost due to some participants having to stay overnight the day before. 

There were 13 participants coming from all over the UK (3 from Peterborough itself); from as far as Edinburgh and Exeter. 

Here is an approximate breakdown of the carbon created and financial costs incurred from their journeys. (Note: all journeys have been calculated as returns). 

Summary of Analysis: 


Train Cost

CO2 Emissions


Liverpool  £99.20 12.58 7hrs 38mins
Newcastle £65.00  33 4hrs 41mins 
London £43.40  13.12 1hr 37mins
Tunbridge Wells £56.90  19.34 5hrs 8mins 
Edinburgh £100.80 49.16 7hrs 45mins 
Exeter £146.30  43.49 8hrs 10mins
Birmingham £38.40  15.8 3hrs 30mins 
Lincoln £16  9.42 2hrs 11mins 
Bristol £103  29.55 7hrs 16mins 
Manchester £105  14.76 5hrs 54mins
TOTAL      £774.00  227.64 KG  53hrs 50mins 


That’s enough to fill a double-decker bus with CO2! Or to provide the energy use of an average house for an entire week! Not to mention the accumulated travel for the participants which adds up to almost 7 full work days! Bare in mind, that these figures don’t even take into consideration the carbon generated by the workshop itself or any overnight stays required ahead of the workshop!  

What makes these numbers even more astounding is that they could have been avoided entirely by using  Virtual Training rather than F2F.  

For participants travelling overseas, it gets even worse. 

We ran a similar analysis on a workshop in Amsterdam, held midweek with fourteen participants from around Europe. For this workshop, the carbon cost reached a staggering 3,922.02 kgs from the flights alone. That is enough carbon to provide a house with energy use for 110 days. 

The carbon cost for a workshop held in Chicago, with participants flying in from around the USA, works out even higher. 

Carbon costs like these are unnecessary when Virtual Training can deliver the same highly interactive experience as F2F training, along with a number of other benefits, but often at a fraction of the cost – both financially and to the environment.  

As it happens, we were already delivering a number of virtual workshops for this particular company but only when they didn’t feel they had enough people registered to justify a F2F workshop. 

After discussing the hidden cost of workshop travel, they decided to run their fully subscribed “Time Management” workshop virtually next time. People logged in from similar locations to the last one, from all around the UK. We reduced the workshop to 100 minutes and still covered all the original content. 

The feedback from the participants was just as strong as the F2F session, it took less time out of the participants diaries, and the travel cost was reduced to zero. This meant there was no additional cost to the company and significantly less impact on the environment. 

Final Thoughts

Have you thought about how you could lessen your impact on the planet and reduce your L&D spend at the same time? What F2F events can you take virtual?
