Globally, we are using more stuff and energy each year [1,2]. Much of this is explained by population growth [3,4], but resource use per person has also increased [5,6,7]. For example, people are eating more food, especially meat , and energy use per person increased by 44% between 1971 and 2015 .
Our consumption of resources is shown by the amount of money we spend on a product or service .
This total financial value of finished products and services is represented by Gross Domestic Product (GDP)[8,9].
GDP varies between regions and with time (swipe!) [8,9] so we standardize it to account for inflation and the currencies of different countries .
We can see our consumption has increased in the graph above (swipe!) because the standardized global GDP per person has risen by 140% between 1970 and 2016 . So clearly to reduce emissions we need to decrease consumption! But is this easy to do? Wait and see in our next post!
