Fuel Cell Black CabLondon could still be saved from the smog that constantly plagues the European Union's most sizable urban area.

According to EcoVelocity, CO2 in London could be reduced by 4,000 tons a week if all of the metropolitan area's black cabs were electric. EcoVelocity calculated the figure based on the CO2 emissions of London's 22,000 registered Hackney carriages (black cabs), but says the figure would more than triple if all the other of London's private-for-hire vehicles went electric too. The study took into account the CO2 emissions of the three most common Hackney carriages on London's roads – the TXI, TX II and TX4 built by Manganese Bronze – as well as the average daily mileage of cabbies.

Since road transport is responsible for approximately 80 percent of the airborne pollution in Central London, where air quality is at its worst, and black cabs account for around 20 percent of that pollution, electrifying the taxis would, by EcoVelocity's calculations, cut the city's pollution by one-fifth. The latest black cab, the TX4, meets only the now-outdated Euro 4 standards.

      Considering the fine particles (nano particles with latest filters) on the city street, this would be an impressive improvement. If only the heavily used bus lanes would transfer towards on-street running light rail transit.

      Do I really care about a CO2 reductions, from a pollution perspective? It doesn't make the air or ground look dirty and I can't smell it. There are reasons to reduce CO2 maybe, but not to reduce the smog in London. CO2 isn't a component of smog.

        I think we can leave it as an "exercise for the reader" to apply some common sense and assume that no tailpipe emissions in downtown London would be better for smog, pollution and general health for eveyone in that general area???

        It's interesting that the linked article never even mentions smog - just pollution in general. It also states that the study indicates a move to EV taxis would reduce the amount of CO2 released by 4000 tons every week - so the article *is* more concerned with CO2 than smog. Also, the US EPA classifies CO2 as a dangerous pollutant, a gas that must be regulated, hence the concern about reducing CO2 emissions here in the US, but I am not aware that the UK DEFRA has classified CO2 in the same manner.

        We don't really have a smog problem in the uk, it's diesel soot that makes the air dirty in London.

      Having commuted by bicycle in London for 6 years, particulates from Black Cabs are the biggest problem - i.e. the palls of black smoke that follow them up the road. Removing them from the road would cut out 35% of the PM10s in London which is probably more important for people's health than CO2.

        @PhilipHa
        Exactly! And the worst is being imprisoned behind those soot farting contraptions when traffic is stuck, and the cabbies refuse to shut the buggered things off ( probably too afraid it'll never start again.. Hehehe)

      Better to have the pollution in the middle of nowhere than right in the city. Diesel is really horrible in the city, maybe not so bad for regular cars that do a lot of highway miles I suppose.

      For all you tree huggers out there, who prate about how valuable used Toyota Pruises are: http://flint.craigslist.org/cto/2554020325.html $1500.00 or best offer. I suspect Chevy Volts will be pretty much given away, once their battery needs replacing.

        $1500 is quite high for a car with 155 k on the clock. Idiot.

        Congratulations, you found somebody offering a cheap car that they've probably abused the hell out of...big deal. Try this one, a 2003 Cadillac Escalade with pics of a very nice ride for $2,750 ROFL: http://atlanta.craigslist.org/atl/ctd/2555454427.html

        "Selling cheap because of the body damage " Great find Jim. Who could have guessed a partially wrecked car would sell cheaply?

      And if the black cabs were white or had solar panels on the roof they would need less air conditioning.

      London cabs are Chinese made garbage with polluting engines. Why on earth did they buy these??????????

        London cabs are made in Coventry. And let's not forget the growing fleet of London Cab FCVs that are being built for the 2012 Olympics (co-developed by Lotus!). http://ecomagnificent.com/2011/04/09/hydrogen-fuel-cell-cabs-arrive-in-london/

      London's pollution would drop 20%...but some other place where the power-plants are located will have a rise of pollution too. And here lies the pipedream about electric cars....at least for now.

        electric is much more efficient and you can power them from windmills, waterfalls, nuclear and solar power. think a little

      Note to Mr. Loveday: CO2 has little to do with smog and local pollution. While I prefer electric, clean burning fuels like CNG or LPG would have a similar affect on local pollution. While CO2 is a green house gas (GHG), it is not a pollutant (even if certain government agencies want to call it as such for regulatory purposes).

        Did you said to these folks to install lpg refueling tanks into their garage and convert these taxis to bi-fuel operation.
