We perform an analysis of the green investments contained in the Italian National Recovery and Resilience Plan (NRRP) by comparing environmental benefits to the investment cost. We compute the future discounted environmental benefits in terms of expected greenhouse gases emission reductions using various estimates of the Social Cost of Carbon. Our results suggest that several projects would not have a positive net present value, unless the discount rate is relatively low and benefits accruing to developing countries receive a higher weight. The fact that investments under the NRRP are financed via long-term debt helps in bridging the gap between costs and environmental benefits. Investments in renewable energy are an exception, as their environmental benefits outweigh the cost within a short time-frame.
