Regenerative Impact Ventures (RIV) is a global advisory, development, and finance agency bringing solutions and support to meet accelerating global development challenges.

OUR MISSION is to validate, commercialize, and scale regenerative development solutions that reverse climate change and biodiversity loss and lead to more productive, resilient, and healthy communities and landscapes.

OUR OBJECTIVE is to be the global leading DBFO (design-build-finance-operate) firm that empowers communities and regions to harness their regenerative potential through smart, distributed, integrated, circular, and nature-based planning solutions

We support our mission and objective by offering a vertically integrated suite of services across four complimentary divisions:

Accelerating Global Development Challenges

> 80% of wastewater is discharged without treatment

< 20% of solid waste is usefully recovered*

*composted or recycled

89% of primary energy comes from non-renewable sources

> 26% of the world’s population is food insecure

By 2040, the global population is projected to increase by 1.4 billion people, with much of this growth occurring in unplanned urban settlements. Were we to provide 100% resource capture and basic service coverage (wastewater and solid waste) to this future population of 9.2B, we would need nearly 6X the current treatment capacity.

This poses an overwhelming public investment burden that will be further exacerbated by expanding funding gaps, socio-economic fragmentation, aging legacy infrastructure systems, and accelerating climate change.


How can cities, regions, and governments meet future demands if they struggle to do so today? 

Our Regenerative Framework – Beyond Sustainability

RIV is advancing a Climate-Positive approach to community, land use, and economic development. Key principles that guide our approach include:

Systemic & Integrated. We analyze issues holistically and leverage synergies across systems to reduce costs and enhance value creation.

Adaptive & Distributed. We promote agile, distributed, and modular solutions and adapt them to unique cultural and ecological conditions.

Circular & Metabolic. We identify ways to transform waste into renewable assets by managing materials, nutrients, and water within circular metabolic processes. 

Data-Driven & Evidence-Based. We utilize science, data, and evidence-based validation mechanisms to ensure projects are accurate and accountable.

Regenerative & Net Positive. We strive to not only reduce and eliminate adverse development impacts (net negative, net zero), but to actively generate Net Positive impacts that enrich, restore, and regenerate the productive capacities of underlying support systems.
