Reduce consumption to reduce emissions?

In our last post we saw that consumption (C) is increasing [1,2,3]. Let’s look at the climate equation from an earlier post:

Total emissions = P x C x E

P = Population (the number of people on the planet)

C = Consumption (everything each person “consumes” in a year: buying a phone, driving a car etc. – anything you do!)

E = Greenhouse gas emissions per service (the amount of emissions caused before, during or after you use each service, which could be an activity or a physical product).

We can see that if we significantly reduce our consumption we can significantly reduce our total emissions. But how easy is this?

There are still around 1.3 billion people living in poverty [4]. In order to give these people better lives, they require things [5] like access to clean drinking water [6], electricity [7], and medicines [8]. Therefore, in less developed countries we want consumption to increase to help improve people’s quality of life [9,10,11]. You can see examples of this in our posted image (swipe!) [5].

But people in high-income countries can and should change consumption patterns [12]. Each person can choose to consume less in total (decrease C) and/or consume things with lower emissions per service (decrease E). Swipe to see our image for this!

However, since we can’t stop consuming things completely we need to look at reducing energy use per service to get emissions down to zero. See this in our next post!
