Why your country's GDP might be hiding its true wealth
In short: Gross Domestic Product is the standard yardstick for economic health, but it captures activity rather than prosperity. By focusing solely on production value, GDP can actually increase while a nation’s long-term resources and environmental sustainability are depleted.
To understand the difference between economic activity and actual welfare, economists distinguish between Gross Domestic Product (GDP) and Net Domestic Product (NDP). GDP is a production concept that aggregates three specific metrics: the value added through producing goods and services, the income earned from that production, and the total expenditure on final products produced within a domestic border. While it is the most widely recognized measure of economic activity, it fails to account for the consumption of capital assets or natural resources.
Net Domestic Product (NDP) provides a more nuanced view by accounting for depreciation. It represents the amount of consumption achievable while preserving capital assets used for manufacturing by accounting for depreciation. Because NDP subtracts these costs, it is often considered a more appropriate metric for assessing welfare and sustainability than GDP. For instance, an activity like the deforestation of the Amazon rainforest would increase GDP due to timber sales, but it simultaneously reduces the level of resources available for future consumption.
The Office for National Statistics (ONS) is currently exploring how to better integrate these concepts into national accounts. A primary suggestion regarding the 2025 System of National Accounts (SNA) suggests categorising natural resource exhaustion as a "cost of production." Adopting this would integrate environmental consequences into NDP figures by treating resource use as an element of the manufacturing cycle. The goal is to move toward a more accurate reflection of how production impacts long-term sustainability.
