Beyond GDP: Operationalising Well-being and Sustainability Indicators in National Budgets

For nearly a century, Gross Domestic Product has reigned as the paramount indicator of national progress. Its elegant simplicity a single number capturing the total market value of goods and services produced has made it the default lodestar for economic policy and a shorthand for societal success. Yet its limitations are now too acute to ignore. Conceived in the aftermath of the Great Depression, GDP was never designed to measure human welfare. It counts the costs of pollution cleanup as growth, while remaining blind to unpaid care work, ecosystem degradation, and the distribution of income. As the global community confronts climate breakdown and widening inequality, a policy revolution is underway: the move to operationalise well-being and sustainability indicators in national budgets.

The problem with GDP is not that it is useless but that it is increasingly problematic as the central measure of societal progress. Research from the WISER (Wellbeing in a Sustainable Economy Recovered) project, supported by the European Commission, is developing a new economic development framework that provides evidence-based policy insights on how to raise the well-being of current generations without sacrificing the well-being of future generations (Costanza et al., 2014). This work synthesizes decades of ecological economics research, arguing that a genuine progress indicator (GPI) that accounts for environmental externalities and social factors provides a fundamentally different picture of human development.

The policy challenge is moving from measurement to budgeting. Several nations are pioneering such approaches. The most comprehensive example is New Zealand, whose Labour government in 2019 introduced the world's first "Well-being Budget." This framework requires ministers to submit budget proposals aligned with specific well-being domains ranging from mental health to environmental quality and to demonstrate their expected impact using indicators from the Living Standards Framework (New Zealand Treasury, 2021). This was not a mere rhetorical shift; it directly shaped funding allocations, with significant new investment directed to mental health and child poverty reduction.

Scotland has adopted a parallel approach through its National Performance Framework, which tracks progress against 81 indicators of national well-being, including community cohesion, biodiversity, and children's outcomes. The Scottish Government's budget process now explicitly links spending decisions to these outcomes through performance-based budgeting (Scottish Government, 2018). Similarly, the OECD's Better Life Index has provided a comparative framework that allows member states to benchmark their performance beyond income, covering dimensions from work-life balance to civic engagement (OECD, 2020).

The technical architecture for this shift is sophisticated. It involves constructing satellite accounts that supplement traditional national accounts, developing composite indices that are methodologically sound, and building public sector capacity in outcome-based performance management. The statistical challenge is real: how to aggregate disparate well-being dimensions without arbitrary weighting, and how to ensure the indicators are resistant to political manipulation (Stiglitz, Sen, & Fitoussi, 2009). The landmark Commission on the Measurement of Economic Performance and Social Progress, led by economists Joseph Stiglitz, Amartya Sen, and Jean-Paul Fitoussi, provided a definitive framework for addressing these questions, distinguishing between current well-being and the sustainability of well-being over time.

Operationalizing well-being metrics does not mean abandoning economic analysis. Rather, it enriches the policy conversation with a more complete dashboard of information. A minister proposing a large infrastructure project would still examine cost-benefit ratios and fiscal impacts. But the analysis would now also include the project's estimated effect on local air quality, its impact on community social connections, and its contribution to intergenerational equity. The policymaker's job becomes harder but it also becomes more honest.

The path forward requires institutionalizing this multi-dimensional view within the machinery of government. This means retraining finance ministries, building parliamentary oversight around well-being outcomes, and investing in the long-running data series that make durable measurement possible. GDP will not be dethroned overnight. But by embedding well-being and sustainability within the budget process, governments can begin to make decisions that reflect what citizens actually value, and to build economies that serve people, rather than demanding that people serve the economy.
