PROSPER Salone Climate window

Sierra Leone is one of the most vulnerable countries to climate change in West Africa and among the world’s Least Developed Countries, with limited capacity to adapt to the adverse effects of climate change. Agriculture – Sierra Leone’s second largest economic sector after mining, contributing 59% to GDP – is facing long-term, high-risk exposure to climate change. As a result, there has been a sharp growth in investors’ use of environmental, social and governance approaches to integrate climate risks and opportunities into investment decisions.

Who can apply?

The Climate window targets impact investors, institutional investors, domestic investors and international corporations seeking to invest in Sierra Leone with the aim to support mitigation and adaptation actions that address climate change and respond to the challenges caused by environmental degradation.

To be eligible for a grant, applications must:

  • Include a development rationale for how the grant will support further investment into Sierra Leone
  • Demonstrate how their project will promote investment (local and international) into Sierra Leone’s private sector and enable economic growth, income growth and job creation
  • Target either climate change mitigation or adaptation, or both
  • Prove that the final investment project will be in Sierra Leone.

Investments should broadly fall within the following areas:

  • Adapting and building resilience to the current and future effects of climate change
  • Pursuing low-carbon development
  • Supporting the sustainable management of natural resources
  • Increasing access to clean energy
  • Reducing deforestation
  • Adopting climate-related disclosure measures
  • Carbon capture or carbon off-setting initiatives.

Any sector or sub-sector aligned with climate change mitigation or adaptation is eligible. For example, potential sectors and sub-sectors could include the following:
