Hollande's economic policies are wide-ranging, including supporting the creation of a European credit rating agency, the separation of lending and investment in banks, reducing the share of electricity generated by nuclear power in France from 75 to 50% in favour of renewable energy sources, merging income tax and the General Social Contribution (CSG), creating an additional 45% for additional income of 150,000 euros, capping tax loopholes at a maximum of €10,000 per year, and questioning the relief solidarity tax on wealth (ISF, "Impôt de Solidarité sur la Fortune") measure that should bring €29 billion in additional revenue.
