Ireland Drastically Missing 2030 Climate Retrofit Goals, ESRI Report Warns

Ireland is “materially off-track” on its ambitious 2030 residential decarbonisation targets, according to a new report from the Economic and Social Research Institute (ESRI) that paints a sobering picture of the country’s climate ambitions.

The study reveals that by the end of 2024, deep retrofits reached just 57,932 completions—only 11.5% of the 500,000-home target, while heat pump installations stood at an estimated 14,194, representing merely 3.5% of the 400,000-unit goal. District heating capacity delivery similarly lags behind projections.

Ireland’s Climate Action Plan had set these targets alongside a goal of delivering up to 2.7 terawatt hours of district heating capacity by 2030. The ESRI’s assessment is blunt: even with continued acceleration, “substantial shortfalls” are projected across all three metrics.

The primary obstacle? Cost. According to data from the Sustainable Energy Authority of Ireland, the median cost of a deep-energy retrofit ranges from €22,914 for an apartment to €66,503 for a detached house. Homeowners typically shoulder €16,378 to €42,900 of these expenses, with rental properties facing even steeper price tags.

Beyond financial barriers, the report identifies administrative complexity, information gaps, and the disruptive nature of retrofitting—particularly challenging for elderly households—as significant impediments. The misaligned incentives between landlords and tenants further complicate progress in the rental sector.

The ESRI also flagged a critical structural tension: the construction sector’s limited capacity. Meeting retrofit goals would require approximately 15,000 workers annually to complete 50,000 retrofits per year—labor that directly competes with Ireland’s urgent housing construction needs.

“In the context of an acute housing shortage, and with delivery of new housing units falling short of recent targets, there is an immediate trade-off between upgrading existing homes to meet retrofit goals and building new homes to meet housing demand,” the report stated.

The findings come as the Irish government recently announced its National Residential Retrofit Plan 2026, featuring enhanced grants and a strategic pivot from a “Deep Retrofit Only” approach to a “Step-by-Step” model designed to improve affordability and broaden participation. The new framework expands eligibility, including welfare recipients and Approved Housing Bodies, with grants covering up to 80% of costs.

Minister Darragh O’Brien has pointed to positive momentum, citing over 58,000 Sustainable Energy Authority of Ireland upgrades completed in 2025. However, updated skills analysis projects the need for 63,444 annual retrofits alongside 50,000 new homes—underscoring the scale of the labor challenge.

The report also raised questions about measurement accuracy, noting that Building Energy Rating metrics can “diverge substantially from actual energy use,” potentially overstating achieved decarbonisation.

For policymakers in Washington watching European climate implementation, Ireland’s struggles illustrate the practical difficulties of translating ambitious decarbonisation targets into on-the-ground progress—particularly when housing shortages and skilled labor constraints intensify the policy trade-offs.
