Climate Public Private Partnership Programme (CP3) CP3 aims to demonstrate that climate friendly investments in developing countries, including in renewable energy, water, energy efficiency and forestry are not only ethically right but also commercially viable. It aims to attract new forms of finance such as pension funds and sovereign wealth funds into these areas by creating two commercial private equity funds of funds which will invest in subfunds and projects in developing countries, creating track records of investment performance which should in turn encourage further investments and accelerate the growth of investment in climate.
