In the last three months I have presented at and/or been on panels to discuss transport, covid, the climate emergency and cars. Earlier in March 2021 my Rail Vision for the Cardiff Capital Region was published; this follows Cardiff Council’s Transport White Paper in February 2020 (which I also helped prepare).
To support some further upcoming events, I want to quickly summarise a big change that is coming and is unavoidable, re: car use….whether we like it or not… and I am going to try do this in a few bullet points!
I have also covered some of these details in a recent slide set and several earlier blogs including:
But back to the bullets….
- Climate Change is real, caused by humans and unless we start to make radical changes – including and especially our mobility choices (transport ranges from between 15~25% of total carbon emissions) we risk irrevocable damage to essential ecosystems.

- At the moment (and pre-covid) car mode share was on average over 80% with Public Transport (PT) and Active Trave (AT) in total less than 20%
Figure 2 Senedd Research – Mode Share
- This is in stark contrast to the 1950s and earlier when car use was very much in the minority
Figure 3 Mode Share in UK 1950 – 2015
- Most countries, including the UK and Wales, now have legally binding decarbonisation targets in place. By 2029 Wales needs to have reduced carbon emission by 45% Vs 1990 baseline and 80% by 2050. By 2018 we had reduced by just 29% Vs 1990 and transport in Wales has reduced by a much smaller amount, just 4%; and in the EU overall its gone up!

- Car use is subsidised (it really is!) given the damaging external costs which we all pay through our taxes and degradation of our environment: 160,000 Road Traffic Accidents in the UK each year, 25,000 serious injuries, 1700 deaths (5 a day, including 1 cyclist); induced demand and sprawl; before we get to air quality (20-30k premature deaths per year) particulates and carbon emissions! I should also add the destruction of local town high streets everywhere as a result of the growth of car based shed retail (especially food) and offices all over the country: Spytty Park, Culverhouse X, Trago Mills, Cyfarthfa Retail park, McArthur Glen, Cardiff Gate, Imperial Park, etc, etc and now the perversity of drive through coffee retail!
- Furthermore, cars spend perhaps 95% of their time doing nothing – so huge, embedded carbon costs and a grossly irresponsible and inefficient use of scare natural resources!

- In particular, the phenomenon of induced demand (which is poorly understood including by me until recently) means that unless we introduce demand management measures, all roads will fill up some of the time. You can’t remove congestion…you can only move it around! This video is a good explainer; building more road space generates more traffic. In reality its only 20-30% of peak time traffic that cause 100% of congestion on the M4 example. It is overwhelming clear that we should invest to provide a PT alternative for that 20-30% and price the road to ensure it operates more effectively for those that still need to use it. We really do have more than enough road space!
Figure 8 What sort of future do we want? (I 405 in Los Angeles)
- Now we are facing a car industry greenwash with EVs that are still poorly utilised, getting bigger and heavier (so requiring more energy to move) and often “sold” under lease arrangements that try to persuade us to replace with new every 2 or 3 years.
- Before we electrify our car ecosystem, we need fewer and smaller cars first….and greater utilisation of vehicles through sharing. We also need to keep an eye on innovation…for example small, fast swap modular batteries and battery stations. The idea we are all going to be trailing cables through our front room windows to charge millions of stationary cars using 240V domestic supply is, well, crazy!

To hit the decarbonisation targets in respect of transport, I assert we need to increase public transport mode share from less than 20% today, to over 40%, and reduce car use from 80% to less than 40%; with at least 20% AT (even more in urban areas). This means:
- At least 3 times more Public Transport capacity
- Demand management measure – fiscal (yes and including road pricing! or as I prefer to call it “a reduction in the car use discount”) and physical measures; so less space for cars, especially in urban areas & less volume parking provision in town and city centres, hospitals, retail parks, etc (and certainly not “free parking” which actually encourages more car use)
- More flexible working (combination of HQ, local hub and home working). I did a brief blog on this at the beginning of the lockdown last April.
- A planning revolution to encourage more PT/AT connected city and town centre development and the gradual relocation of all our car based out of town stuff (especially shed food retail, public services, offices, etc) back to town and city centres. I also have written a little on Transit Oriented Development (TOD) in the past.
For Cardiff, the CCR and WG, the Public Transport strategy and vision is getting clearer, and through Transport for Wales some of it is being delivered through the next phase of the “South Wales Metro”.
- Cardiff Council Transport White Paper, including…
- Cardiff Crossrail and Bus Rapid Transit
- More Active Travel and especially segregated cycle routes
- Schemes to limit car access in urban areas (so removing private vehicles from Castle Street for example and reduced access in places like Wellfield Rd)

However, there are still major challenges for government to navigate, including:
- Developing a new methodology for transport planning and demand modelling that reflects the decarbonisation targets – based on “Define and Provide” instead of “Predict and Provide”
- Funding the capital and revenue to support implementation and operation of more public transport. In this context the need for UK Gov to fully devolve powers and funding over rail in Wales to WG is essential!
- Developing and implementing “road pricing” and other demand management measures – this is fundamental, fair and necessary (see the link below to my blog on the radical fiscal measures our economy needs) if we are to start living in balance with nature
- Ensuring Transit Oriented Development is adopted all over Wales.

That’s it really….
For those still interested, I have also penned some thoughts re the radical fiscal overhaul our economy needs
