EDF Group announced it was included in the FTSE4Good Index, a series of "ethical investment" stock market indices.
"Transparency is vital in our business," Claude Nahon, EDF's head of sustainable development, said in a statement. "It is the basis for real dialogue with our stakeholders and a precondition for public acceptance of our work."
The French energy company said its inclusion in the index highlights its aim to become a market leader in clean energy development. It set a goal of making renewable energy comprise 25 percent of its energy mix by 2020.
The company added that it's one of five nuclear power operators to be included in the index.
World leaders are reviewing their commitment to nuclear power one year after a magnitude-9 earthquake and tsunami led to a meltdown at Japan's Fukushima Daiichi nuclear power plant.
