How do you measure the wealth of a country? For many, gross domestic product is the first and maybe only measurement that comes to mind. While GDP measures the monetary value of the goods and services produced in a given year, it doesn’t provide a complete picture of a country’s wealth, or how sustainable that wealth will be in the long term. In many cases, economic growth is happening at the expense of nature, and therefore at the expense of future prosperity. To understand the sustainability of growth, we must look at the value of all the assets that generate income and ultimately well-being.
