The World Bank estimates that over the next 15 years, the global economy will require $89 trillion in infrastructure investments in cities, energy, and land-use systems, and $4.1 trillion in incremental investment to make the low-carbon transition that will keep the planet under a 2 degree Celsius rise in temperature. Developed countries are working to meet a commitment made in 2010 to mobilize $100 billion a year from public and private sources by 2020 for climate mitigation and adaptation in developing countries.

Global investment in low-carbon energy technologies is growing and the costs of renewable energy and falling, but it will be a challenge to achieve the scale of investments required without the appropriate policy, institutional, industry, and financial frameworks.

Most of the low-carbon investment required in both developed and developing countries must be provided by private financial actors. Governments and custodians of international public finance need to deploy limited public finance in ways that leverage this private-sector investment. Building on traditional and developing new development finance tools, the focus is on mobilizing ‘climate investment’ in the most cost effective way, including by providing Information, developing skills, providing targeted incentives, and putting in place conducive policies that reduce different types of risk..


UNEP helps the finance community invest in the renewable energy and energy efficiency sectors. Our programmes combine technical assistance and targeted financial support such project development funding.


  • Brings together first mover financiers and renewable energy project developers to share some of the additional costs related to early stage investments and mitigate risks
  • Helps mobilize new and additional investments in the energy efficiency and clean energy end –user finance space, by providing knowledge and financial tools and building capacity of financial sector players, technology providers and government institutions, and
  • Helps governments access international climate finance to achieve their national low-carbon development ambitions.
