Plan B: Catalonia shows a post-growth future can still meet its people’s needs

A region famous for its industry, tourism and dense Mediterranean cities has become the testing ground for one of the most consequential questions in contemporary environmental science: can a modern European economy meet the needs of its population without economic growth? A new report from the Institute of Environmental Science and Technology at the Universitat Autònoma de Barcelona (ICTA-UAB) answers with a carefully argued yes. The study, titled “Pla B. Per una Catalunya resilient en un escenari postcreixement” (Plan B: for a resilient Catalonia in a post-growth scenario), lays out, with unprecedented quantitative detail, the public policies required to decouple well-being from the expansion of output while respecting planetary boundaries. Its authors argue that the measures are not utopian speculation but a practical policy program, applicable in Catalonia and transferable to national and international contexts facing the same converging pressures of climate disruption, resource strain and social instability.

The report emerges from the REAL post-growth research project, funded by a European Research Council Synergy Grant and led by Giorgos Kallis and Jason Hickel of ICTA-UAB together with Julia Steinberger of the University of Lausanne. In this research tradition, economic growth is treated not as an unqualified good but as something closer to an addiction: a pursuit that no longer reliably improves people’s lives while progressively compromising the resources and environmental stability on which future well-being depends. Post-growth scholarship therefore seeks ways to raise quality of life without depending on continued expansion of production and consumption, which is increasingly doubtful in viability and incompatible with the limits of a finite planet. The Catalan study translates that abstract ambition into a concrete inventory of interventions, each calibrated to the region’s actual socio-environmental conditions.

The report’s principal investigator, Salvador Pueyo, acknowledges that there are reasons for pessimism given the scale of global and everyday problems, but he insists that the game is not over, and that defining solidly grounded policies is an immediate necessity for emerging from the current crisis. Giorgos Kallis, principal investigator of REAL, describes the work as a fundamental study, the first to calculate how a region can transition toward a post-growth future, demonstrating that such a transition is feasible. A central methodological contribution of the report is its quantification of the resources demanded by current modes of living and production, compared against the potential capacity of Catalonia and of the planet as a whole. Pueyo emphasizes that the analysis does not focus on individual responsibility but on the potential for collective change, while conceding that a collective shift of this magnitude will inevitably also involve changes in consumption habits.

Nowhere is the quantitative rigor more evident than in the energy chapter. The report presents data showing that moving away from fossil fuels is urgent and, crucially, is not currently happening. Meeting Catalonia’s entire present energy consumption exclusively through renewable sources, the authors calculate, would require occupying the equivalent of 4.9 percent of the region’s territory, a burden with consequences that would be difficult to bear; increasing consumption further would make the problem even worse. To avoid this, the plan calls for a sharp reduction in energy use combined with the sequential deployment of renewables, beginning in locations with lower environmental impact and moving later to higher-impact sites, preserving future opportunities to mitigate damage. Notably, the report finds that the bulk of current electricity consumption could be covered using rooftops and degraded land, provided the Catalan government, the Generalitat, plays a proactive role: covering 60 percent of available rooftop areas is estimated to require an investment equivalent to 4.5 percent of the Generalitat’s non-financial budget over five years, an outlay the authors consider recoverable.

Mobility receives equally specific treatment. To cut energy consumption and environmental impacts, the report proposes curtailing private motorized traffic while strengthening public transit, and redirecting subsidies for electric cars toward leasing services, vehicle-sharing systems and community fleets. Air transport is singled out as a sector in need of rapid contraction, addressed through targeted fiscal tools. The report demonstrates that sharply reducing air traffic would save resources, reduce impacts and lower vulnerabilities while simultaneously generating public revenue and tempering housing prices, a combination of benefits that makes it one of the more politically attractive proposals in the plan. The document also draws attention to the emerging challenge posed by data centers, whose swelling energy appetite threatens to undermine any conservation gains achieved elsewhere in the economy.

The agrifood chapter offers perhaps the study’s starkest accounting. Catalonia, the authors find, lacks the agricultural capacity to feed both its human population and its livestock industry simultaneously, even if meat exports were halted completely, while sustainable extensive farming could cover only a small fraction of current consumption levels. The report therefore deems a drastic reduction in the consumption of animal-based products indispensable, and prescribes a transition toward an agroecological model centered on small-scale farmers rather than large corporations, prioritizing food security over exports. Agroecological intensification, the report argues, would maintain high productivity while delivering far greater benefits for sustainability, rural livelihoods and public health. Beyond Catalonia’s borders, the authors identify a coordinated international reduction in animal-source consumption as perhaps the last remaining hope for the climate, because even the rapid phase-out of fossil fuels, more necessary than ever, is no longer sufficient on its own to respect the 1.5 °C limit. On the emissions side, to avoid exhausting the carbon budget compatible with that limit by 2028, the report proposes a 7 percent annual reduction in fossil emissions in Catalonia beginning in 2026, alongside the food-system shift.

The economic pillar of the plan is inseparable from these physical transformations. As Pueyo puts it, a post-growth transition requires a profound transformation of economic, fiscal, labor and social policies, because economic tools must drive sustainability even at the expense of growth, and when growth ceases to be a priority or is simply no longer viable, redistribution becomes key to meeting basic needs. The report proposes an adaptive eco-voucher scheme (EVA) that combines an environmental consumption tax with a complementary currency distributed to citizens, penalizing higher polluters while compensating those with a lower environmental footprint. A progressive land value tax would curb speculation and lower housing costs, with revenue earmarked to expand public rental housing, support housing cooperatives and fund social spending. These instruments, the authors argue, allow fiscal policy to reward low-impact behavior rather than simply punishing consumption, a design intended to protect low- and middle-income households through the transition.

On labor and social rights, the plan proposes a cushion income (renda coixía), a tailored welfare benefit protecting low- and middle-income households, and, as an alternative or complement, a job guarantee focused at least on those facing the greatest difficulty finding work, estimated to cost 2.4 percent of the Generalitat’s budget. Recommendations include shortening the workweek to improve quality of life and share caregiving duties, and guaranteeing public or cooperative employment for workers displaced by the eco-social transition. The governance layer of the plan is equally ambitious: a commitment to ethical banking, the cooperative model and public-community partnerships, binding citizens’ assemblies for strategic decisions, and mechanisms to ensure that leadership positions are held by individuals motivated by the common good. The method underlying the whole report is data and statistical analysis, grounding each policy in measured resource flows rather than rhetoric.

Perhaps the most politically consequential finding concerns unilateral action. Globally, the authors argue, there is no alternative path to improving everyone’s quality of life; yet implementing post-growth policies unilaterally is far more difficult for a specific territory, especially one inside the eurozone. Research under the REAL project has advanced post-growth economic policy for the eurozone as a whole, but a major challenge remained: determining what Catalonia can do while the rest of the currency union has yet to act. Pueyo admits that at the outset the team feared Catalonia’s margin for unilateral maneuver would be minimal, but they are now more optimistic, having compiled existing policies and developed new ones that can, in principle, be applied without waiting for external coordination. The researchers hope these policies will serve as a benchmark for other countries, and that even if unilateral implementation is insufficient on its own, Catalonia’s example could supply the leadership needed to drive the international coordination that major global challenges demand. The report frames the present global landscape as the failure of the globalized economic model, and its central challenge as articulating a new form of cooperation focused on people and the planet, drawing on historical precedents that demonstrate the viability of such collective action.
