Cyclists pollute more than cars, claims Swiss economist (and something about beef)

Cyclists can be up to four times more damaging to the environment than cars… because of beef and milk, apparently.

Well, at least that’s the view of Professor Reiner Eichenberger, a specialist in fiscal and economic policy at the University of Fribourg, Switzerland.

“Today everything is climate. Many want to replace the car with public transport and bicycles. They believe that the latter burden society less and are climate-friendly. That’s wrong,” Professor Eichenberger, widely credited as one of Switzerland’s most influential economists, claimed in a column for the weekly German-language Swiss newspaper Handelszeitung.

In the, shall we say, intriguing column, Eichenberger goes on to claim that, according to figures from the Swiss Office for Spatial Development and the Federal Statistical Office, when it comes to noise, accidents, infrastructure and operating costs, public transport and cycling “cost many times more than the car”.

Even when the official stats suggest that people using public transport and bikes are more beneficial to the environment than motorist, Eichenberger argues this is “largely due” to the organisations’ “creative accounting” and “official tricks”.

So, how do cyclists harm the environment and impact climate change more than cars? Well, you see, it’s all down to beef (and not the kind typically found on the live blog comments section).

The economist writes:

Although the whole debate is about energy and climate, the bicycle is treated as a perpetual motion machine. But cyclists need additional energy. For this, they have to eat more, which puts a strain on the climate.

Economical cars need 5 litres of gasoline per 100 kilometres, causing 12kg of CO2 emissions, i.e. 120 grams per vehicle kilometre – and 30 grams per passenger kilometre for a four-person occupation.

Cyclists consume around 2500 kilocalories (kcal) per 100 kilometres during normal riding. They have to compensate for energy and muscle consumption through additional food intake. So, they would need about 1 kilo of beef for the 2500 kcal. This causes them to produce 13.3kg of CO2.

Meat-eating cyclists therefore cause 133 grams of CO2 per passenger-kilometre – four times the number of well-occupied cars. If they obtain driving energy from milk, they emit 35 grams of CO2 per passenger-kilometre, which is still almost 20 percent more than the car. Unfortunately, this miserable record also applies to vegans.

So, there you have it. Unless you’re propelled solely by noodles – which, the helpful professor points out, will lead to protein deficiency at some point – you’re harming the environment on your bike more than the queue of traffic on the way home from work.

The comments section for this one was particularly amusing, with some readers describing the article as a “laughing stock” and an “embarrassment”.

“Joggers and hikers are even worse than cyclists, because they need more food (due to the inefficient locomotion) per 100km. Pedestrians are the climate killers par excellence,” wrote one astute reader.

“A ‘professor for financial and economic policy’ who writes such rubbish shakes my belief in the Swiss education system. Or is this supposed to be (moderately funny) satire?”

I think he may be on to something there (or at least I hope so).

Over on Twitter, meanwhile, one user got to the heart of the matter: “Bike consumption: 1 kg of beef/100 km. How many cattle does a Miguel Induráin have on his conscience?”

The question that keeps me awake at night…

‘By that logic, body builders must be more damaging to the environment than nuclear meltdowns’: Reaction to Swiss professor’s ‘cyclists pollute more than cars’ theory

Professor Reiner Eichenberger’s theory that cyclists pollute more than cars – based on something to do with cows, I think – has baffled quite a few of our readers.

BalladOfStruth gamely tried to suss it all out, to no avail:

So, let me get this straight – to arrive at these numbers, he’s:

  • Based his consumption-per-kilometre figures on what a cyclist would eat to fuel a long endurance ride and applied this to shorter rides where most cyclists wouldn’t eat anything extra (I never used to eat extra calories to fuel my commutes, despite his numbers assuming I’d need 200g of beef per day).
  • Based his figures on cyclists only eating just about the most inefficient and highest carbon-emitting food we are capable of creating (farmed beef). It looks like he has a pop at vegans too but doesn’t seem to quantify this with any numbers.
  • Ignored the fact that drivers will, in fact, also eat.
  • Compared cyclists only with “well occupied” cars, when we all know that most aren’t.
  • Compared cyclists only with “economical cars”, when many aren’t.
  • Ignored all other factors in running a car (waste products, fossil fuel production, manufacturing the vehicle, etc).

By his logic, body-builders must be more damaging to the environment than nuclear meltdowns. What utter, utter nonsense.

JustTryingToGet… also thought that the Swiss economist’s methodology needs a bit of work:

The numbers need to be re-run based on 1kg of cake.

Now there’s a study I could get behind…

HGV close pass in Balham (credit -Bill Hulley, Twitter)
“I don’t think the wand was stopping them”: Scary HGV close pass video sparks debate on safe infrastructure, dangerous driving, and “discourteous” cycling

When is cycling infrastructure not actually cycling infrastructure?

When a lorry driver can plough straight over the top of the traffic wands and into the bike lane, probably.

The above video, captured by cyclist Bill Hulley as he rode through Balham, south London, at the weekend, depicts quite a few hairy moments in just 40 seconds.

First, Bill narrowly squeezes between the overtaking HGV driver and a van protruding into the cycle lane from an adjoining road, before the lorry driver begins to veer into the bike lane, making light work of the light segregation in place by knocking over the wands like it was a game of Mario Kart.

“Could we have some kerbs on CS7 please?” Bill tweeted. “The wands are helpful but aren’t very good at deflecting HGVs.”

The rather frightening clip naturally prompted a debate on Twitter, about both the driving on display and the usefulness (or otherwise) of lightly segregated cycling infrastructure:

Local Labour councillor, active travel campaigner and live blog regular Jo Rigby – who has previously highlighted that paint does not necessarily equal infrastructure – responded to Bill’s clip by tweeting that “this is why I support the use of wands to protect Tooting and Battersea residents”.

Though some weren’t convinced:

Meanwhile, some Twitter users (both cyclists and motorists, it has to be said) preferred not to focus on the need for properly segregated bike lanes or the bowling alley-style driving on display, but instead chose to blast the cyclist’s “discourteous” riding (some stronger words may have been used):

And finally...

Why can’t all cyclist vs driver clips be like this? Footage of cyclist apologising to motorist for hitting van goes viral

This clip is almost two months old, but has come on to our radar this week after the Sun shared it with the always fun and not-at-all-infuriating headline, “Watch as a cyclist smashes into the back of a van – nobody can believe how the men handle it”.

@norfolkdashcam The Van Driver was fine about the situation. No dramas. #Accident #Cyclist #Cycle #Van #Norfolk #NorfolkDashCam #UKRoads #DashCamFootage #DashCam #UKDashCam #CaughtOnCamera #Fail #CyclistsOfTiktok ♬ original sound - Norfolk Dash Cam

The video – posted on TikTok (which explains why we haven’t seen it) by the Norfolk Dash Cam account – depicts a cyclist exhibiting a lack of attention while riding through King’s Lynn and hitting the back of a van in the process. ‘Smashes’ may be overplaying the incident slightly, but hey, it’s the Sun.

After the bump, the cyclist then rides up to the van driver’s window to explain what had happened and apologise.

The motorist then – drumroll, please – replies: “Don’t worry, that’s alright.”

The extremely apologetic cyclist, perhaps surprised by the driver’s nonchalant response, continues to explain that he “slipped forward on my handlebars”, much to the chagrin of the motorists stopped behind the van, who sounded their displeasure through that age-old medium, the car horn.

Most of the TikTok users commenting on the video praised the decent, patient, and I would almost say human, interaction between the two road users, with one writing that it was “so nice he owned up to it” and that there was “no damage done” in any case.

However, as is always the case with these things, other users decided to have a go as anti-cycling bingo callers, with one writing (with more than a hint of sarcasm, I suspect), “No doubt the cyclist has insurance to pay for any damages anyway.”

“They need insurance if they’re gunna use the roads”, “Cyclist insurance details pls lol”, and “This is why cyclists should have to have insurance!” came some of the other original responses to the video.

Filling out the rest of the bingo card, one TikTok user – failing to distinguish between a bit of metal and an actual human being – said, “Now, if it been the van touching the cyclist…”

“One in a million. A cyclist that apologises,” another wrote.

Ah, you can’t win them all, can you?

Surface 604 Element electric fat bike - riding
Dutch cycling organisation concerned about rising popularity of electric fat bikes

Dutch Cyclists’ Union Fietsersbond, which campaigns for the expansion and improvement of cycling infrastructure in the Netherlands, has expressed its concerns about the growth in popularity of electric ‘fat bikes’ in the country.

According to Fietsersbond’s Ester van Garderen, electric bikes with fat tyres have surged in popularity since the Netherlands made helmets mandatory for scooter users. Van Garderen told the Telegraaf that the bikes can also be easily fitted with an illegal throttle lever that can increase their maximum speed from 25kph to 50kph.

They drive very fast,” Van Garderen said. “And you don’t hear them coming because of the electric drive.”

The Telegraaf has linked the popularity of these enhanced e-bikes among teenagers to the surge in serious cycling incidents involving young people aged between 12 and 17 in recent years.

The Fietsersbond says it has received several complaints from concerned road users about the fat bikes. “And rightly so, because don’t forget that about 600 people die in traffic every year,” Van Garderen added. “People aged 60 and older hardly dare to use the bicycle path anymore.”

Lachlan Morton set to target Mark Beaumont’s round-the-world record

Lachlan Morton, the Australian currently redefining what it means to be a professional cyclist, is not beginning to turn his attention towards possibly his biggest two-wheeled adventure yet: breaking Mark Beaumont’s round-the-world record.

Scottish endurance cyclist Beaumont set the current Guinness world record in 2017, when he circumnavigated the globe by bike (covering 29,000km) in just 79 days, despite a strong headwind and a crash in the Pyrenees slowing his progress as he neared his final destination, Paris.

> Mark Beaumont completes round-the-world ride in 79 days to smash Guinness World Record

EF Education-EasyPost pro Morton is, of course, no stranger to epic, long-distance rides. In March, he cycled over 1,000km non-stop from Munich to Poland’s border with Ukraine to raise funds for refugees fleeing the war-torn country.

The year before, the Australian rode the entire route of the Tour de France, including transfers, solo and unsupported – and even sometimes in crocs.

> Data reveals huge strain of Lachlan Morton’s solo Alt Tour vs. EF-Education Nippo’s Tour de France efforts

Now, his EF team boss Jonathan Vaughters – who has also encouraged Morton to take part in the fledgling gravel scene – has told Cycling Weekly that the next big aim will be to break Beaumont’s record, though it may have to wait until 2024.

“What we wanted to do was to try the around the world record [in the second half of 2023], but the sticking point on that right now is Russia,” Vaughters said.

“We don’t think that’s going to be possible next year, so we’re trying to come up with a plan B right now. What that is, we’re not sure yet.”

Lachlan Morton - Photo Credit Grubers 05

While JV maintains that Morton remains “very keen” to break the round-the-world record, the current geopolitical situation means that a proper crack at gravel racing will will constitute his main goal for 2023.

“He won’t be doing any road races, really,” Vaughters said. “In the early part of the year he wants to get away from doing real ultra events and kind of focus on trying to win in gravel.

“He has lost a lot of his explosive power from doing these massive 4,000km events. So, he’s training a little bit more in an explosive manner.”

Morton confirmed to Cycling Weekly that he had spoken with the team about a proposed round-the-world attempt, though there was “nothing concrete” yet.

“Beautiful” or “bloody useless”? New bike stand divides opinion

This, ahem, interesting new bike stand at the KARST contemporary art gallery in Plymouth (flagged by road.cc reader hirsute in the comments section of yesterday’s live blog) has certainly divided opinion online:

What do you think? A contemporary art masterpiece or a prime example of form over function?

After obtaining a PhD, lecturing, and hosting a history podcast at Queen’s University Belfast, Ryan joined road.cc in December 2021 and since then has kept the site’s readers and listeners informed and enthralled (well at least occasionally) on news, the live blog, and the road.cc Podcast. After boarding a wrong bus at the world championships and ruining a good pair of jeans at the cyclocross, he now serves as road.cc’s senior news writer. Before his foray into cycling journalism, he wallowed in the equally pitiless world of academia, where he wrote a book about Victorian politics and droned on about cycling and bikes to classes of bored students (while taking every chance he could get to talk about cycling in print or on the radio). He can be found riding his bike very slowly around the narrow, scenic country lanes of Co. Down.

How good is cycling for the environment? Co2 emissions of transport ranked - BikeRadar - October 30, 2020 -

"Cycling has a carbon footprint of about 21g of CO2 per kilometre. That’s less than walking or getting the bus and less than a tenth the emissions of driving
About three-quarters of cycling’s greenhouse gas emissions occur when producing the extra food required to “fuel” cycling, while the rest comes from manufacturing the bicycle
Electric bikes have an even lower carbon footprint than conventional bikes because fewer calories are burned per kilometre, despite the emissions from battery manufacturing and electricity use
If cycling’s popularity in Britain increased six-fold (equivalent to returning to 1940s levels) and all this pedalling replaced driving, this could make a net reduction of 7.7-million tons of CO2 annually, equivalent to 6% of the UK’s transport emissions

We want to compare the emissions from cycling with driving the equivalent journey. Internal combustion cars are considerably less economical over short trips, due to idling, cold starts, stop-starting etc.

The ECF estimates that for short journeys that compete with cycling, the average European car emits 266g CO2e per kilometre of driving, including both tailpipe and well-to-tank emissions.

This figure is still not ready to be compared to cycling because cars can carry multiple people. The ECF estimates that for such short trips, the average car has an occupancy of 1.16 passengers. That works out at 229g CO2e per passenger-kilometre from fuel use and fuel manufacturing.

Total Co2 emissions for cars compared to bikes

Adding this to the manufacturing emissions (42g/km) gives a total of 271g CO2e per passenger-km of driving. That’s around 13 times the emissions from cycling.

What’s the bottom line?

By these calculations, cycling has the lowest carbon footprint of any mode of personal transport, even when compared to walking.

From a climate perspective, it makes sense for as many journeys as possible to be made by bike.

On an individual level, cycling instead of driving (or any other method of travelling) can make a positive impact on your carbon footprint.

But on a national scale, cycling has a limited role in addressing climate change. Because cycling is restricted to short journeys for most people, it can only replace a small fraction of the kilometres covered by cars.

Even if half of all sub-5-mile car journeys were replaced with cycling (a deliberately optimistic scenario) this would save around 7.7-million tons CO2e in the UK, equivalent to 2 per cent of UK domestic emissions in 2016. Not to be sniffed at, but not a silver bullet."

Also true. This is where we can look beyond "assuming nothing else changes..." though because with this scale of change all things will not remain equal.  It seems clear that a considerable reduction in travel consumption - bluntly: fewer medium-to-long journeys, and travelling less far in general - will also be needed*.

There is also the overall financial benefit (never mind "quality of life") from more self-powered low-impact local travel.

* "Needed" - assuming we want to make a dent in some of our current pollution/health/resilience issues.  Which not everyone agrees!  This may be impossible because humans and this requires compromise, discipline and cooperation which we just don't have the ability for.  Or maybe "not only do we not 'need' it, we will fight to keep 'growing' as any reduction in this is anathema to us / if we stop the others will overtake us / take us over.  It's natural - keep competing and expanding until you run out of resources".

He's massively undersold the emissions per passenger Km for cars.

For a start, you can multiply his number by 3-4 because we all know most cars won’t have four people in them. Then you can probably double them again based on his definition of an "efficient" car. Then, you can add the daily average calorific intake (what? 2,200-2,500 cals - in beef of course) to his emissions per passenger Km. And finally, you can create a distance threshold before which most cyclists wouldn't actually intake extra fuel (20km?).

That brings the car back to well above the bicycle, even in his fantasy world where everyone has a cow-only diet.

Sounds like this chap may have been moonlighting on road.cc recently!

It's probably just a case of "follow the money" e.g. where's he / his institution / his favourite politician getting their money from.  (I'd be surprised - nay delighted - if this was a sinister cycling mafia or "useful idiot" permaculturists / the local branch of "Tyre extinguishers" but I somehow feel not).  It may be that he's taken creative licence of the "externalities of motoring" e.g. drawing a rather narrow circle around the *cost* of this activity.  This is very common too.

More usefully and positively I've read that actually the most energy efficient mode of transport* is the electric unicycle / monowheel.  Hawkinspeter will be smug!  After that, an e-bike, then a normal bike.  Escooters are near this but are let down presumably partly by higher friction from the wheels / losing more energy over small bumps and also by short lifetimes.

The key point for me is all are not only much more efficient than cars and other motor vehicles but have a host of other benefits - they're just more suited to human transport needs in general.  (Just a passing nod to the rabbithole of "transport needs vs. wants" e.g. I need to get to the hospital, to the out-of-town shops,  take my child to the good school, get away to the Seychelles by plane...)

Horses (or cycles) for courses.  I favour non-powered cycles for most as you still get excellent energy efficiency.  They're much simpler and less resource-intensive - you avoid batteries (if you run dynamo lights), charging etc.  Scooters / velomobiles and others have different pros and cons outside of just efficiency of course.

* Caveats - for a human on land (assuming at a certain low-ish speed, for normal transport purposes) and assuming you're not dining on steaks of some hyperpredator which you roast over a crude-oil fire...

I've seen figures that plausibly make an e-bike more carbon efficient than human power with an average diet if you both make your batteries using locally mined lithium, and charge them with renewable energy. So possibly in Canada, less so in the UK.

The assumptions he has made to reach his outcome are a bit implausible but the overall topic is quite interesting.

Taking the figures from: https://shrinkthatfootprint.com/food-carbon-footprint-diet/

You get vegans producing 1.6kg CO2 for every 1000 calories and an "average" diet producing 2.6kg.

According to Strava I burn about 33 calories per km.

30 kilometres therefore has a carbon footprint of between 1.6 and 2.6kg depending on what I've eaten. If we call it 2.1kg as an average that's 70g per kilometre.

From a pure climate perspective you may well be better off taking public transport or sharing a ride in a small car.

Caveats:
1) It's entirely possible I've got my maths wrong!
2)I have no idea how accurate Strava's calorie estimates are.

You have also forgotten to factor in the difference in trip types between motorists and cyclists.

Most car journeys are "purposeful", that is to say they go from one place (point A) to another (point B) to achieve a given task. There are exceptions to this, such as Sunday driving and F1 races, but these are outliers.

By contrast, a vast percentage of cycling journeys are leisure-based and serve no purpose other than personal pleasure (point A to point A). In fact, in the strictest sense of the word you couldn't really call them "journeys" at all, as they start and finish at the same place with no meaningful stop in-between. As they don't go anywhere, these cyclists are producing pollution for nothing.

So this difference in trip types should also be factored in to this leading economist's calculations, and would skew pollution further towards cycling.

Yet according to the national travel survey:

"The most common purpose for a trip by car was for leisure (30%)." It also says that 15% of car journeys are for commuting yet 20% of cycle journeys are for commuting.

Using actual data, there doesn't seem a lot of difference. Assembled this off the DfT website. 2020 was obviously exceptional because of Covid, 2019 is probably more representative of normal conditions, but even in 2020 leisure trips by cycle didn’t account for “a vast percentage”.

What is not factored in there is that most people in the west are at a calorie surplus most of the time. (Obviously not all people, obviously not all the time. I am not an idiot.)

The food they are eating to power those journeys at 70g/km would be eaten anyway and then cause a burden on the health system or require a car journey to a gym to burn off.

As David Hembrow points out, you need to exercise, and about half an hour / 15 km / 9 miles a day of cycling meets that need. So the first half hour at least should count as zero. Avoiding becoming a burden on the healthcare system reduces your carbon emissions per year (although it may increase your lifetime carbon emissions due to your extra years of living.)

You're assuming they don't adjust their calorie intake after exercising.

"I cycled to work today so I'm going to have another slice of cake" is definitely not something I've ever said...

There are, obviously, a huge number of variables to take into account but it is interesting quite how carbon intensive exercise is. IIRC ebikes have a lower lifetime carbon footprint than regular bikes for that reason.
