Why OwC
The Escalating Climate Crisis
South and Southeast Asia are heating at twice the global average, driving floods, droughts, and deepening energy insecurity. Millions are already at the frontlines of this crisis.
Disproportionate Gendered Impact
Women make up 80% of those displaced by climate disasters, yet remain under-represented in energy and climate decisions — limiting collective progress towards equity and resilience.
Non-Aligned Capital Deployment
Over USD 5 billion in climate finance enters South Asia each year, but three-quarters bypass grassroots solutions.
OwC connects capital to community-driven action, ensuring funding flows where it creates real, inclusive transformation.
What We Aim To Achieve
We accelerate Asia’s transition by mobilising capital, coalitions, and community power — putting two million women at the centre of low-carbon, climate-resilient change. By 2028, OwC aims to:
01
Catalyze climate impact
Cut CO₂ emissions through grassroots-led mitigation and adaptation models.
02
Engage women at scale
Partner with 500,000 women, reaching two million people through collective climate action.
03
Mobilise capital for change
Channel USD 20 million in public, private, and philanthropic finance into inclusive local solutions.
04
