Conservation doesn't have to be slow, vague, or sidelined. In Quantified, Joe Whitworth lays out a results-driven approach that brings the precision and impact of Silicon Valley into the heart of environmental work. Drawing on strategies used by high-performing companies—clear metrics, bold targets, real-time data—Whitworth shows how environmental efforts can move from well-intentioned to high-impact.

As president of The Freshwater Trust, Whitworth has helped reimagine river restoration using what he calls "quantified conservation": a method that uses rigorous data, innovative technology, and measurable outcomes to deliver environmental progress with the speed and certainty of a start-up. Quantified offers compelling case studies from this work, particularly in water conservation, but the approach applies far beyond rivers—to climate, land use, agriculture, and beyond.

This is conservation reengineered for today's world: ambitious, efficient, and rooted in accountability. Quantified invites policymakers, funders, and changemakers to stop settling for incremental wins and start building environmental solutions that scale. For anyone ready to rethink how change happens—and make it stick—this book offers a powerful playbook.
