China has 350 million electric two-wheelers, 20 million EVs. China reduced air pollution from transportation by 80% in a decade. Delhi: 442. Lahore: 334. Beijing: 16. These are the levels of PM 2.5, one of the principle measures for air pollution, on November 19.

Now compare the amount of renewables China is putting up?

They add coal power because it's super fast to build, but it's not a permanent solution.

Let's not compare Delhi or Mumbai in monsoon season. Get the readings from Delhi in summer or winter and then see the pollution yourself.

Meanwhile I was replying to a comment that just cherry-picked a day. Yes, autumn is the brief good time in Beijing due to prevailing winds, shrug.

Cherry picking a single day to try to demonstrate a widely accepted trend is lazy journalism.

Cherry-picking to try to portray the opposite of the generally accepted truth is much more problematic.

highway != public transport And pollution from bus or tram is much easier to control. Looking at you petrolheads who like to "Rolling coal"

Yes but in London you are never far from a highway you cannot get away from them. In London now many if not most buses are electric.

Are we classing A-roads as "highways" now? If not, I have no idea what you mean when you say you're never far from a highway in London. There are no motorways through London.

This particular brand of confrontational nuclear “advocacy” does not help nuclear. Please consider stopping it.

In what world is simply asking if someone supports nuclear power confrontational? It really is weird how many people are enthusiastic about stemming climate change but don't support one of the few non-intermittent sources for carbon free energy.

"Do you support nuclear power? I'm asking because I believe it's a requirement for grid stability/current battery solutions can't sustain demand during solar downtime"

That is a defensible question, that can be argued/countered, but it's not the question posed.

Conservatives flipped on multiple of their policies after Reform's success on local election in 2025 and started to copy Reform UK. Even the Labour shifter right after 2025.

How's Reform UK Ltd. done since then? They've lost 2 by-elections and beaten a bin. Sterling job I guess if you listen to any of their members.

They're polling at parity with the party in government...

I agree. Some guy picks some specific a day in the past, says "look China good". Another one picks a random day (today) and it paints a diff picture. Meanwhile generally accepted truth rooted in facts is the number of coal plants and generally policies that put manufacturing first. individuals using EVs don't make a dent

City dwellers are the ones that use public land to store their cars. Of the three Villages I know well (my sisters, the one I lived in until moving to a larger 8000 person town, and the one with the primary school) I can’t think of any Likewise the tiny hamlets I drove through on the way to school didn’t have people parking on the road, there’s simply no room. You occasionally get delivery vehicles stop and it causes…

I'm thinking mostly of eg terraced streets in villages and towns. Similar to cities in that there tends to be a single space for parking on the street but multiple car owners per house on average. Different to cities in that there isn't remotely the public transport infrastructure to support getting rid of cars, or the private facility to support electric overnight charging for the longer distance car-commuting etc t…

So in rural areas there’s no parking for the street as that’s where the cars that drive are. You get pasig places and occasional some idiot will park in them briefly.

Even including your towns the vast majority of houses have off street parking, at least according the the rac

You have a very niche issue.

1) storing car on public land at home and office

2) driving excessively long mileage each day

3) having a small capacity car

This is a tiny number of people.

So what's the reason for those pm2.5 levels?

Not at all. You're quoting from a report based on data from a Net Zero campaign. But let's give it the benefit of the doubt and assume it's accurate, 60-70% having access to electric overnight.

That's still leaves millions (?) of households with on street parking.

Most commuters outside cities get on quite ok with normal cars - because they have to - and a third of them is hardly "niche".
