In an economic environment shifting towards more responsible and sustainable use of production means, Morocco has been pushing its economic expansion following the same footsteps as the Saudi Vision 2030. Transforming 52% of the economic landscape into green and inclusive economy. Solar, wind and green hydrogen will become the main energy sources. The use of high-speed rail, tram-way projects and BRT projects with electric buses are a major sustainable driven mobility projects initiated by Ministry of Transport and Logistics, initiatives that aim to link sustainable driven cities such as Rabat, Benguerir and Bouskoura, where as well green driven ventures are implemented from green-spaces to smart-cities in which sustainable practices are the engine of waste-water treatment, road signage and urban plannings. Using a panel-data methodology, this study examines the relationship between green-energy investments and financial success in Moroccan civil-engineering firms from 2019 to 2024. The dependent variable is return on invested capital (ROIC), whereas sustainability indicators include energy efficiency and CO₂ reduction. The results show that businesses that use more green energy generate higher profits, especially in capital-intensive industries like construction and cement. According to scenario projections, energy performance and profitability will continue to rise in 2030 (assuming 4% GDP growth). The results highlight the strategic aspects of Morocco's industrial green-transition and how significant these initiatives are.
