People who claim that population growth is a big environmental issue are shifting blame from the rich to the poor.
A paper published last year in the journal Environment and Urbanization shows that the places where population has been growing fastest are those in which carbon dioxide has been growing most slowly, and vice versa. Between 1980 and 2005, for example, Sub-Saharan Africa produced 18.5% of the world’s population growth and just 2.4% of the growth in CO2. North America turned out 4% of the extra people, but 14% of the extra emissions. Sixty-three per cent of the world’s population growth happened in places with very low emissions(2).
Even this does not capture it. The paper points out that around one-sixth of the world’s population is so poor that it produces no significant emissions at all. This is also the group whose growth rate is likely to be highest. Households in India earning less than 3,000 rupees a month use a fifth of the electricity per head and one-seventh of the transport fuel of households earning Rs30,000 or more. Street sleepers use almost nothing. Those who live by processing waste (a large part of the urban underclass) often save more greenhouse gases than they produce.
The paper’s author, David Satterthwaite of the International Institute for Environment and Development, points out that the old formula taught to all students of development – that total impact equals population times affluence times technology (I=PAT) – is wrong. Total impact should be measured as I=CAT: consumers times affluence times technology. Many of the world’s people use so little that they wouldn’t figure in this equation. They are the ones who have most children.
While there’s a weak correlation between global warming and population growth, there’s a strong correlation between global warming and wealth.
I’ve been taking a look at a few superyachts, as I’ll need somewhere to entertain Labour ministers in the style to which they’re accustomed. First I went through the plans for Royal Falcon Fleet’s RFF135, but when I discovered that it burns only 750 litres of fuel per hour(5) I realised that it wasn’t going to impress Lord Mandelson. I might raise half an eyebrow in Brighton with the Overmarine Mangusta 105, which sucks up 850 l/hr(6). But the raft that’s really caught my eye is made by Wally Yachts in Monaco. The WallyPower 118 (which gives total wallies a sensation of power) consumes 3400 l/hr when travelling at 60 knots(7). That’s nearly one litre per second. Another way of putting it is 31 litres per kilometre(8).
In May the Sunday Times carried an article headlined “Billionaire club in bid to curb overpopulation”. It revealed that “some of America’s leading billionaires have met secretly” to decide which good cause they should support. “A consensus emerged that they would back a strategy in which population growth would be tackled as a potentially disastrous environmental, social and industrial threat.”(9) The ultra-rich, in other words, have decided that it’s the very poor who are trashing the planet. You grope for a metaphor, but it’s impossible to satirise.
James Lovelock, like Sir David Attenborough and Jonathan Porritt, is a patron of the Optimum Population Trust (OPT). It is one of dozens of campaigns and charities whose sole purpose is to discourage people from breeding in the name of saving the biosphere. But I haven’t been able to find any campaign whose sole purpose is to address the impacts of the very rich.

It’s time we had the guts to name the problem. It’s not sex; it’s money. It’s not the poor; it’s the rich.
