About Us

At Oneworld Colab (OwC), we advance inclusive climate action and equitable energy transitions across South and Southeast Asia.

We amplify the leadership of communities and women most affected by climate change, ensuring they shape solutions that are just, scalable, and rooted in local realities.

Through partnerships, capacity building, and innovative finance, we bridge policy and practice, turning community knowledge into measurable, lasting impact.

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

Catalyse 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

Strengthen grassroots collaboratives

Build capacity for 100+ community organisations to access finance, shape policy, and scale innovation.

05
