Italy's National Energy Agency (ENEA) has documented cumulative energy savings equivalent to the annual electricity consumption of two major industrial regions combined—Emilia-Romagna and Veneto—achieved through efficiency measures implemented between 2021 and 2025. The milestone represents 85% of the national target set under Italy's integrated climate and energy roadmap, though recent policy changes have begun to slow the momentum.
Why This Matters
• Total savings reached 5.08 million tons of oil equivalent (Mtep) over four years, falling just short of the 6 Mtep interim goal outlined in the Piano Nazionale Integrato per l'Energia e il Clima (PNIEC).
• Tax deduction schemes accounted for 52% of all savings, but 2025 saw a 37% drop compared to 2024 following reductions in fiscal incentives.
• Thermal Account (Conto Termico) subsidies grew, while White Certificates and sustainable mobility programs declined slightly, signaling shifts in policy effectiveness.
The findings were unveiled during the 15th Annual Energy Efficiency Report presented by ENEA in Rome, with remarks from agency president Francesca Mariotti and energy efficiency department director Ilaria Bertini. The presentation offered a granular look at how Italy's energy-saving mechanisms performed in a period marked by escalating energy costs and evolving subsidy frameworks.
Tax Breaks Drove Half the Gains—Until They Didn't
Fiscal deductions for energy retrofits emerged as the most powerful tool for driving household and commercial efficiency upgrades, generating 2.67 Mtep in cumulative savings between 2021 and 2025. These incentives—ranging from the Superbonus 110% to standard deductions for insulation, window replacements, and heating system upgrades—allowed millions of property owners to offset renovation costs through tax credits.
However, the data reveals a sharp contraction in 2025. Savings from tax-incentivized projects fell to 0.24 Mtep, a 37% decline year-on-year. The drop directly correlates with the scaling back of incentive rates enacted by the Italy Cabinet in late 2024, which lowered maximum deduction percentages and tightened eligibility criteria amid budget pressures.
For homeowners and landlords, the message is clear: the era of ultra-generous tax breaks has ended. Those planning energy renovations now face smaller rebates and longer payback periods, which may delay or deter projects unless energy prices remain elevated enough to justify out-of-pocket expenses.
White Certificates Lose Steam, Thermal Subsidies Gain Ground
Italy's White Certificates (Certificati Bianchi) program, designed to incentivize industrial and commercial efficiency projects, posted 0.115 Mtep in savings for 2025, down 4.5% from the prior year. The cumulative total of 0.83 Mtep aligns with intermediate PNIEC projections, but the downward trend suggests diminishing returns as the most cost-effective projects have already been completed.
In contrast, the Conto Termico scheme—which subsidizes renewable heating and cooling installations such as heat pumps, biomass boilers, and solar thermal systems—delivered 0.131 Mtep in 2025 alone, bringing the four-year total to 0.476 Mtep. This uptick reflects growing consumer interest in replacing fossil-fuel heating systems, driven by both environmental goals and volatile natural gas prices.
For residential and commercial property managers, the shift points to a practical opportunity: thermal upgrade subsidies remain robust and are likely to persist as Italy pursues decarbonization targets, making heat pump installations and biomass systems financially attractive even as broader tax incentives wane.
Sustainable Mobility Plateaus as EV Adoption Slows
Sustainable mobility measures, including electric vehicle (EV) incentives, public transport electrification, and infrastructure grants, contributed 0.404 Mtep in savings during 2025, a 6% decline compared to 2024. Despite the dip, these programs remain among the largest contributors to Italy's overall efficiency gains.
The slowdown mirrors broader European trends, where EV sales growth has plateaued following the expiration of purchase subsidies and rising vehicle prices. Italy's automotive sector also faces headwinds from reduced consumer confidence and competition with cheaper imports, complicating efforts to accelerate fleet electrification.
Cohesion fund projects—regional development initiatives co-financed by EU structural funds—remained steady at 0.022 Mtep in 2025, unchanged from 2024. These programs typically focus on public building retrofits and district heating systems in southern regions, where energy poverty and infrastructure gaps are most acute.
What This Means for Residents
The report underscores a transitional moment in Italy's energy policy landscape. While the country has made substantial progress toward its 2025 interim target, the deceleration in tax-driven savings signals that future gains will require either renewed fiscal support or a fundamental shift in consumer behavior and technology costs.
Practical takeaways for those living in Italy:
• Act soon on remaining incentives: If you are considering energy retrofits, prioritize Conto Termico applications for heating system upgrades. These subsidies remain accessible and have shorter processing times than the scaled-back tax deductions.
• Calculate real payback periods: With lower deduction rates, projects like facade insulation or solar panel installations now require 8-10 years to break even in many cases. Run the numbers carefully before committing.
• Monitor 2027 PNIEC revisions: Italy must submit an updated climate and energy plan to Brussels later this year. New targets or incentive structures could reshape the financial case for efficiency investments.
The 85% Threshold and What Comes Next
Reaching 85% of the PNIEC interim goal is a significant achievement, but it also highlights the challenges ahead. The final 15%—the gap to 6 Mtep—will likely prove harder to close as the easiest, most cost-effective efficiency gains have already been captured. Industrial energy audits, deep building renovations, and behavioral change campaigns will need to play larger roles.
ENEA's analysis suggests that sustaining momentum will require a rebalancing of policy tools. Over-reliance on tax deductions has created fiscal strain, prompting the government to tighten eligibility and cap total expenditures. Meanwhile, programs with smaller budgets—like the Conto Termico—are delivering higher marginal returns, suggesting room for reallocation.
For businesses operating in Italy, the shift toward industrial efficiency programs and digital energy management tools presents both compliance obligations and competitive advantages. Companies that proactively adopt monitoring systems and participate in White Certificate schemes can reduce operating costs while contributing to national targets.
Italy's energy efficiency trajectory reflects a broader European dilemma: how to balance ambitious climate goals with fiscal discipline and economic competitiveness. The next two years will determine whether the country can close the remaining gap through smarter policy design or whether external factors—energy prices, technological breakthroughs, or EU mandates—will prove decisive. For now, the message for residents and businesses alike is to maximize available incentives while preparing for a less subsidy-intensive future.
