PURPOSE
Vision:
a society where the economy is operated as a wholly owned subsidiary of the environment, an environment where all human beings and species thrive.
Mission:
to align financial capital with sustainability goals.
Capital for Sustainability (C4S) is designed to serve as both:
- a market demonstration tool for how the for-profit financial ecosystem can support sustainability.
- a driver for systemic change so that the rules of the economy favor all people and the planet.
THE PROBLEM
Finance for sustainability is flowing at a greater pace than ever before, but it is not flowing fast enough to solve pressing challenges such as the climate crisis.
Only $0.15 out of every $1.00 is mobilized for climate solutions in low-and-middle-income (LMI) countries.
Private climate finance for LMI countries (domestic & cross-border) was a measly $43 billion in 2023.
80% of climate finance for LMI countries is public finance, thus lacking the abundant capital available from private sources (~$450 trillion globally).
LMI countries require about $2.2 trillion in investment per year to support energy transition needs. In 2022, only $544 billion in investment flowed into renewable energy projects in LMI countries.
Globally, $1.1 trillion is needed annually to transition to regenerative agriculture, yet only $28.5 billion is being invested annually. The agrifood investment needs are greatest in LMI countries.
OUR SOLUTION
What
- Revolving philanthropic fund to invest and shape systemic change for sustainability, focusing on climate solutions.
Where
- Focus on low and middle income countries (also known as the Global South and Global Majority).
- Eligible countries throughout Africa, the Americas, and Asia.
Why
- Most of the world’s growth and greenhouse gas emissions are taking place in the Global South.
- LMI economies have on average at least 4% annual growth vs <2% for OECD economies.
Who
- Managing Director, regional leads, analysts, chief of staff.
- Remote team; staff based globally.
How
- Source opportunities
- Convene players
- Invest + Fund
- Influence
- Evolve
Inclusive Lens
- Intentionally inclusive of historically excluded groups in each economy.
- Just transition principles.
