A waste of space

21st September, 2009

Climate change is the most urgent reason for drastically reducing motoring but there are many others. Top of the list is the space they waste. Here’s a blast from 1973:

The problem is that of designing an environment for people, who occupy a few square feet and need tens of square feet to move, which can also accommodate a large number of motor cars, which occupy hundreds of square feet and need thousands of square feet to move. This has consequences for housing design and for urban form. There are also other characteristics of motor cars which damage the local environment so that a large number of them in an urban setting has the effect of encouraging people to spread out spatially in trying to avoid the nuisances of heavy traffic.

Put simply, the choice is between compact no-car Venice and sprawling all-car Los Angeles.

Which do you choose?

That’s easy, I choose Venice

I’m more of an LA man myself

Excellent video Car Free Venice.

Postscript July 2015: Carbon emissions from making cars

A report by Climate Central,  Roadmap to Climate-Friendly Cars: 2013, concludes

Our state-by-state analysis reveals that because the manufacturing of an electric car causes more greenhouse gas emissions than manufacturing a comparable gasoline-powered car, an electric car must be driven sufficiently long distances using sufficiently low-carbon electricity for it to have lower total lifecycle greenhouse gas emissions than the gasoline-fueled car.

They give carbon emissions from the manufacture of different types of car as (converted to metric tonnes CO2e):

Electric Car     12.3
Gas Car            7.4
Hybrid Car        7.1

The UK Climate Change Act of 2008  aims to cut greenhouse gas emissions by 80% by 2050 to approximately 2.5 tonnes CO2e per year.  At these estimates the emissions from the manufacture of an electric car are 5 years of this total budget.

Postscript January 2016: Carbon emissions of a car in a year

Tail pipe emissions from the SMMT for new cars in 2015 (including VW?) uprated a bit to 160 gm CO2/km – because published figures only account for measured tail-pipe emissions. They do not include emissions in processing and transporting oil. Average distance per year is taken as 12,700 km

This makes just over 2 tonnes per year or 80% of the 2.5 tonnes per year the Climate Change Act of 2008 is aiming at for 2050.
