Social acceptance of low-carbon transport technologies is a crucial but frequently underrepresented dimension in energy system optimization models (ESOMs), despite its potential relevance for the design of effective decarbonization policies. This study examines the role of social acceptability in the transition of the European Union transport sector toward climate neutrality by integrating behavioral factors into the open-source ESOM TEMOA-Europe. In particular, social acceptability is represented through technology-specific hurdle rates, used as proxies for perceived risk and financing barriers, alongside assumptions on declining investment costs for low-carbon vehicle technologies. Four scenarios are developed and compared: (i) a Base scenario, (ii) a scenario with reduced hurdle rates for battery electric and fuel-cell vehicles, (iii) a CostSC scenario with lower investment costs for green truck technologies, and a Net0 scenario (iv) imposing a binding net-zero emissions constraint by 2050. The analysis evaluates these scenarios based on technology uptake, system costs, CO2 emissions, and critical raw material requirements. Results show that, in the passenger car sector, lower perceived risk can substantially accelerate electrification and achieve emissions reductions comparable to those obtained under stringent regulatory constraints, in some cases at lower overall system cost. By contrast, the freight sector appears considerably less responsive to such demand-side measures, indicating the need for stronger regulatory intervention. The findings also highlight that deep transport decarbonization implies a substantial increase in demand for critical raw materials, reinforcing the importance of complementary recycling and supply-chain policies.

Determinants of Energy Efficiency and Renewable Energy in European SMEs
This paper empirically investigates the factors driving the adoption of energy efficiency (EE) and renewable energy (RE) measures in a sample of 8,213 Small and Medium-Sized Enterprises (SMEs) in European countries. Our results suggest that sustainable energies actions (EE and RE) are highly persistent both at the firm level and across countries and that there…
Energy Reforms and Consumer Prices in the EU over twenty Years
To what extent have the European households benefited from the energy reforms of the last two decades in the EU? The core ingredients of change have been, in different proportions and timing across countries: privatization of formerly state-owned enterprises, unbundling of networks, market liberalization and regulation. This paper summarizes some empirical findings of a team…
Baltic Gas Supply Security: Divided We Stand?
Estonia, Latvia and Lithuania, depending entirely on Russia for their gas supply, want to invest in gas supply security. The European Commission encourages them to do so by conditioning subsidies to the building of joint regional infrastructure. In the face of serious political and legal hurdles to Baltic gas security co-operation, Brussels’ approach might be…
