Abstract: Abstract The transition to a low-carbon economy is a complex process that, from a technical perspective, requires coordination of different market players, significant technology advancements and sufficient financial resources. The transition to a low-carbon energy system is a capital intensive process. Different technological options at different scales and different time frames will be required for the successful transition to a low-carbon energy system. The economic impact on countries that transform their energy system depends on a multitude of factors including their energy system profile, the access to low-cost financial resources, whether they are market leaders in the production of clean energy technology and their ability to assimilate knowledge that is produced elsewhere. In this study, we use a large scale applied CGE model to compute the macroeconomic implications of the investments required to reduce by 76% as compared to 1990 levels the GHG emissions of the Italian energy system within a context of global concerted GHG mitigation action. The focus of the analysis has been on the Italian economy and energy system as Italy is both an equipment manufacturer, its energy system is largely based on fossil fuels and its financial system is currently under pressure following the elevation of public debt and deficits. The model-based results suggest that the Italian economy can benefit from the low-carbon transition in the coming decades in case Italian firms and households have access to low-cost financial resources, Italian manufacturers acquire market shares in the production of clean energy technologies and technological progress is rapid driven by innovation and economies of scale. The average annual GDP growth of Italy in the period 2015–2050 can be 1.3% in the case that Italy reduces drastically its GHG emissions and the associated cumulative expenditures sum up to one trillion euro.
