In the following sections, I assume a rule of thumb that a decent, morally justified lifestyle must keep with a total budget of 100 tonnes CO2e for the next 50 years. This is the basis for the Carbon Budget Morality Index (CBMI) discussed in Are you evil or very, evil?. The 100 tonnes 50 year budget is classed by the CBMI as ‘shameful’ but at least it’s morality index is below the CBMI ‘evil’ level. In this post the ‘shameful’ level will be referred to as CMBI-s level.
Traditionally green belts were seen to stop urban sprawl and were the ‘green lungs’ of the city. This emphasised public health issues such as slum clearance. The policy is seen as a major instrument in terms of protecting the environment against environmental damage as a result of overdevelopment. It is a policy which is believed will to ‘protect the countryside’.
With coal pollution receding, York’s air improved and so did the look of the inner city terraced houses. Since the 1970s they have gradually lightened in colour and their value has risen. Houses that 1948 Plan for York described as “worn out houses” costing a thousand or so pounds in 1970, now sell for over £200,000. That’s a 20 fold increase in real terms.
The countryside is not as clean and green as it seems. In part 2, I noted the large carbon footprint of modern non-organic agriculture, particularly the methane emitted by ruminants (cows, sheep, goats &etc.) and the use of nitrogen compounds derived from the energy intensive Harber Bosh process. I also discussed the carbon footprint of “modern”, non-organic, food production but there are other unwelcome impacts. Three of these:
The cost of building a traditional house is a modest part of the cost of a new home: In York it is less than the cost of the land when it has planning permission. Not long ago it has been possible to build an individual 3 bed roomed house for about £50,000. I know someone had one built for £50,000 – on land they already owned.
Bricks and mortar houses built in the conventonal style
Key point: Planning permission adds enormous value to land
A plot of land big enough for a house costs less than £1,000 at agricultural prices.
In places like York, that becomes £50,000, sometimes much more, once the planners give building the go ahead. Planning permission makes no immediate difference to the land: but its name on a certificate in a council office gives an enormous unearned bonus to the land owner.

Sea level isn’t just rising, it is accelerating. It did so during the 20th century, and has done so even more quite recently. ABC news reported the story, based on just-published research (Nerem et al. 2018), that the latest satellite data now show it plainly. The authors of the new study conclude:
When taken with a rate of sea-level rise of 2.9 ± 0.4 mm/y (epoch 2005.0), the extrapolation of the quadratic gives 654 ± 119 mm of sea-level rise by 2100 relative to 2005, which is similar to the processed-based model projections of sea level for representative concentration pathways 8.5 in the IPCC Fifth Assessment Report. Stated alternatively, the observed acceleration will more than double the amount of sea-level rise by 2100 compared with the current rate of sea-level rise continuing unchanged.
More planet destroying stuff is produced if we have full employment and greater productivity
stuff =workers * productivity
We must cut planet destroying stuff. A top planet destroyer is the car. As Car-free cities pointed out, a city without cars is pleasant and much cheaper. So stop the polluting production lines and have more local market gardens
