Two days ago I posted a neat interactive map of carbon footprints across America. It was taken from an Atlantic Cities article. But in the same post, I questioned the (Atlantic Cities) article’s headline and main assertion that increasing population density won’t help to curb greenhouse gas emissions.
This didn’t make sense to me.
Well it turns out that the supporting research data was slightly misinterpreted. According to the Per Square Mile blog, the UC Berkeley study associated with the interactive map reveals a more nuanced relationship between population density and carbon emissions. It turns out that people who live in the middle of nowhere (rural residents) actually have fairly low carbon footprints. Even though they’re reliant on cars, they tend to drive and consume relatively little.
And so initially, as population densities increase, so do carbon footprints. That is until it reaches about 3,000 people per square mile. At that point, carbon emissions start to drop off dramatically—roughly 35% on average from suburb to city.
Below is a graph I found in the comment section of the original Atlantic Cities article that demonstrates this phenomenon. Population density is on the x-axis and carbon emissions are on the y-axis.
So here’s the big takeaway. If you’re looking to optimize around your carbon footprint, you need to pick a side: Either be urban or be rural. But don’t be somewhere in the middle. Don’t be suburban.
The Globe and Mail published an article yesterday morning called, “Why a lower loonie is (mostly) good for Canada." It talks about the recent decline of the Canadian dollar from parity last May to roughly USD $0.92 today. But that the drop is essentially because of a rising US dollar.
Irrespective of what’s causing the devaluation though, the article takes the tone that it’s generally good for the country:
“On net, this could be seen as a good thing because it’s making Canadian goods and services more competitive,” said Michael Devereux, a professor at the University of British Columbia’s Vancouver School of Economics.
But this viewpoint always gets me concerned.
Canadian goods and services shouldn’t be competitive because they’re cheaper; they should be competitive because they’re the best damn good and services in the world. And so my fear with statements, like the one above, is that it almost makes us believe that a weak dollar is a prerequisite for competitiveness. It’s not.
