Vast amounts are being invested in the energy transition worldwide, with optimistic expectations of economic growth and green job creation. Yet, we crucially lack ex-post validations of the multiplier effects widely used to quantify new green jobs. Focusing on the French Energy Efficiency Obligations scheme, this paper provides the first ex-post estimate of the employment effect of a large energy-retrofit investment program. We exploit a discontinuity in the provision of subsidies and use a novel synthetic control method on disaggregated data to estimate regional-level employment effects. We estimate that the scheme created 1.4 jobs per million euros invested.
