Globally, only one in 50 new cars were fully electric in 2020, and one in 14 in the UK. Sounds impressive, but even if all new cars were electric now, it would still take 15-20 years to replace the world’s fossil fuel car fleet.
The emission savings from replacing all those internal combustion engines with zero-carbon alternatives will not feed in fast enough to make the necessary difference in the time we can spare: the next five years. Tackling the climate and air pollution crises requires curbing all motorised transport, particularly private cars, as quickly as possible. Focusing solely on electric vehicles is slowing down the race to zero emissions.
For context: The environmental impact of PRIVATE JET travel can be over 1000 times more than other travel modes. Aviation produces just under one billion tonnes of carbon dioxide emissions annually, accounting for 2.5% of global CO2 pollution.
I’m going to call bullshit, the biggest sources of emissions for logistics and transport aren’t consumers. It’s industry use, including airlines and sea freight.
Even if you don’t include sea freight, then passenger cars are still only 45% of total transport emissions.
The title is even very clearly worded as an opinion, with it being “important” being intentionally subjective language. Get some bicycles and shit, support cyclist infrastructure, but also definitely support electric rail, planes, and freight.
I don’t think electric planes are practical without some serious battery tech to get the weight down. I’m more interested in just reducing use of planes generally. So get high speed rail on land and slow down shipping a little and harness wind power where possible. Most things can take an extra week or so to arrive, and local logistics can use either hydrogen (collected using solar/wind power) or batteries.
Bro that was news like a year ago

Not to mention there are also Hybrid planes since like 2011 with Boeing’s Diamond EA36 E Star or more recently the EAG’s 70+ seat hybrid plane announced in 2020.
The readily available technology aside, I agree the world could be run a lot more ethically and efficiently.
can carry nine passengers up to 250 miles…It’s not clear yet that this transition will be possible for much larger passenger jetliners, but short- and medium-range planes could make the switch with much less pain.
It’s an interesting proof of concept, but like EVs, it’s not going to scale well to larger vehicles. We need significantly better battery tech (e.g. maybe the solid state lithium batteries Toyota and others are working on) to make that a reality.
Hybrid aircraft are certainly interesting though, and I think hybrid in general is the way to go. Electricity is generally better at acceleration (i.e. takeoffs), and fossil fuels have lower weight per unit of energy so they’re better for sustained power (e.g. cruising altitude). I’m a huge fan of hybrid cars, and think they’re way better than EVs for transitioning. You don’t need to give up range, yet you get better fuel economy. However, my understanding is that we’re talking like 5% better fuel economy, not 30-50% as in cars, so it’s going to be a marginal improvement.
Lifting a bunch of heavy stuff into the air is always going to be more costly energy-wise than moving it along land. So we should be focusing on fast ground transportation instead of more efficient air transportation because we already have good solutions for ground transportation (high speed rail, bullet trains, etc) and just need to pay the upfront cost to get it off the ground (ha!). Aviation imo should be limited to things that need to be fast, and rail should be out main form of long distance transportation.
honest question is it practical to shop for 4 people using a bike? how do we get around the need to move things? i,guess if you had an e bike and a trailer it could work?
I grew up in village (population ~3000, 0.85 mile²) and as a kid, the local butcher, greengrocer, post-office/local shop, two small grocery stores and an offlicence (package/ABC store) had literally everything you could need.
By the time the year 2000 rolled around they had been driven out of business by supermarkets that were 3x further away.
This isn’t a solution but just a reminder that things were very different and it wasn’t that long ago.
There are many ways to make that work, and what happens is usually a combination of one or more of these factors:
- Living/working a short distance away from a grocer, so it’s a quick trip that can happen any day of the week
- Having a grocer in the commuting route such that a quick stop doesn’t really add any extra travel time to your day
- Shop for the next week or two of groceries instead of buying a lot of things in bulk for the month
- Forego big wholesale purchases like getting 3 month’s worth of toilet paper at once for big savings
- Having a cargo bike or at least some extra pannier/baskets to increase capacity
Using an e-bike helps, but I wouldn’t say it’s as big of a factor as those above. I don’t have one, don’t think I will any time soon.
I’m good with having 1, 2 and 3. I still get wholesale stuff at a discount, but I get those delivered to my place instead. The delivery fee is offset by purchasing in bulk. But for everything not wholesale, I get it sorted with a 15 minute detour on my way back from work once a week. This is all pretty easy to make it happen, but only because I live somewhere (Vancouver downtown) that has a decent urban fabric and passable cycling network.
In the Netherlands they use bikes like these with a large cargo area that can carry goods or even kids. And you can get them in electric too. I live in the US and I’ve been considering getting one, but I live in a downtown-ish area which is much easier than suburbia.

When I did groceries with a bike I just used a backpack and made more frequent trips. I think it was practical because going more frequently meant I had more fresh foods and could get just a thing or 2 to utilize other things I already had on hand. It also helped get in a little extra exercise. Granted, this was shopping for 2 and not 4.
Moving things is still probably going to require a car but that’s more of an edge case and not a daily thing.
Let the exploitation-class cycle to Davos.
Yeah, I’ll just haul my kids around on an electric bike when it’s 20 degrees F (-7 C) with a windchill around 0 (-18 C), which also coincides with EVs getting absolute shit range because current batteries hate holding charges at that temperature. Also, I drive a 20 year old vehicle with 190,000 miles that I paid $3000 for 6 years ago or so. EVs and even E-bikes cost a whole lot more than that without the utility.
On top of that, calling vehicles that contain lithium batteries “zero-carbon” is laughable. The mining, refining, and manufacturing process in itself is an environmental disaster. I agree we need to find new modes of transportation powered by methods other than burning coal, natural gas, and dinosaur juice, but we don’t currently have the solution to this problem.
Manufacturing electric cars generates a bit more emissions than internal combustion cars, at least now while the technology is relatively young. Last time I read about it, an internal combustion car would catch up and pass the electric equivalent in emissions in a couple of years of normal use.
EVs getting absolute shit range because current batteries hate holding charges at that temperature
That’s blatantly false and shows just how little you know. The reduced range is due to the heating (both cabin and battery) performed. You don’t even need to heat the battery, but it will perform better when warmer.
There is no significant waste heat on EVs like the ~70% there is on ICEs, so the energy for heating cannot be passively recovered but has to be actively spent. If you disabled all heating (which is obviously not feasible), the reduction in range would be significantly less.
The reduced range is due to the heating (both cabin and battery) performed.
Right, so they still get reduced range in the cold. I now understand the “why” part of it.
You don’t even need to heat the battery, but it will perform better when warmer.
Except that in extreme cold like the region gets where I live, apparently you do actually need to warm up the battery if you want it to take a charge.
As for Tesla, that’s a non-starter for me. Even setting aside my feelings about their CEO, the build quality isn’t something I’d accept anyways even if there was an option that was viable in my case.
The bottom line is that the cost of entry, lack of an option that comfortably carries 5 people and a large dog, and the lack of charging infrastructure (in my area at least) are barriers that most people don’t want to, or can’t deal with.
I do agree that we need an option to phase out ICE vehicles, but we’re just not there yet for a whole lot of people.
Yes for fast charging (>50kW) the battery needs to be warm so it doesn’t get damaged, this goes for all EVs and isn’t Tesla-specific.
But yeah EV range is an issue for some, although not the vast majority. For most people, these issues are theoretical because they so rarely actually use their car in a way that they would encounter them. In reality it’s only an inconvenience they might encounter a few times per year, if at all. Most driving by far is done well within winter range of any EV on the market, if you have the ability to either charge at home or at work with “slow” AC charging.
