Living lab position
What does sustainability mean at Duke Farms?
Duke Farms is more than a destination. It is a living lab where conservation science, sustainable operations, land stewardship, convening, and public learning reinforce one another. Across our campus, the work of restoration, clean energy transition, wildlife conservation, and climate action is made visible through daily operations—from land, water, buildings, and agriculture to fleet, equipment, and visitor experience. In this way, Duke Farms demonstrates practical strategies that reduce emissions, restore ecological function, enhance biodiversity, sequester carbon, and help others imagine and implement a nature-positive, carbon-negative future.
At a glance
How does Duke Farms model sustainability in practice?
Duke Farms treats operations as part of its conservation mission. The way the property manages energy, buildings, land, water, materials, agriculture, food systems, fleet and equipment, and public learning is part of the model. Energy was one of the first areas Duke Farms focused on, and other sustainability pillars are being added and strengthened over time.

| Land | Restore ecological function and beauty, improve soil health, and support biodiversity. |
| Energy | Generate clean electricity, conserve energy, electrify systems, eliminate fossil fuel use, and pursue emissions reductions at the lowest possible cost. |
| Buildings | Align retrofits, master planning, electrification, and capital budgeting with carbon emissions reduction goals, overall sustainability, and the lowest possible cost. |
| Biodiversity | Put biodiversity first while connecting habitat work with climate resilience and carbon sequestration. |
| Water | Manage water use, water quality, stormwater, wastewater, wetlands, and watershed health. |
| Fleet and Equipment | Reduce emissions from vehicles, equipment, charging infrastructure, and operating choices at the lowest possible cost. |

The model
How does Duke Farms turn values into measurable action?
The operating model follows a simple discipline: set clear goals, reduce harm, restore ecological function, test practical solutions, document and monitor results, and share what works. This approach changes what Duke Farms does operationally every day, and how decisions are made. It also uses a phased approach to sustainability enhancements over time, since several steps may be needed to achieve demanding goals at the lowest possible cost. Duke Farms intentionally favors strategies and solutions that others can replicate beyond our own borders.

Operations domains
How does Duke Farms manage land, energy, water, agriculture, and operations?
Each domain connects a practical operating need to a broader sustainability outcome, from land stewardship and clean electricity to agriculture, fleet and equipment, public learning, and peer adoption, with cost treated as a real constraint that shapes decisions.
Land
What we do
Use restoration, long-term stewardship and adaptive management to restore ecological function and support biodiversity.
Why it matters
Land management shapes biodiversity, ecosystem function, climate resilience and the long-term health of all natural systems.
Current initiatives
Floodplain reforestation, grassland management, habitat restoration, and adaptive management and applied research.
What others can learn
Large properties can make land management part of a sustainable operating model rather than a separate conservation project.
Energy
What we do
Use the Natural Systems Energy Plan (NSEP), Duke Farms' decarbonization plan, to conserve energy, generate clean electricity, and electrify buildings, vehicles, and equipment.
Why it matters
The NSEP platform reduces greenhouse gas emissions and supports lower-carbon operations, resilience, and long-term cost control.
Current initiatives
Two solar arrays, battery storage, distribution upgrades, EV charging, electrification, and energy monitoring.
What others can learn
A decarbonization plan works best when conservation, clean electricity, electrification, storage, and measurement are planned in a comprehensive way and well integrated.

Buildings
What we do
Integrate sustainability into all maintenance and long-term capital planning. Sequence conservation, efficiency, controls, electrification, and historic-building retrofits.
Why it matters
Buildings use significant energy and shape comfort, maintenance, resilience, preservation, daily operations, and long-term cost.
Current initiatives
Cutting edge sustainability standards, adaptive reuse, controls, envelope work, heat pumps, master planning, and capital planning.
What others can learn
Historic and operating buildings need phased improvements that align preservation, long-term capital budgeting, and sustainability goals.
Biodiversity
What we do
Put biodiversity first while tracking how restoration, land management, and carbon sequestration interact.
Why it matters
Maximize carbon sequestration without negatively impacting biodiversity.
Current initiatives
Native species work, habitat monitoring, restoration metrics, and applied research on biodiversity in peri-urban environments.
What others can learn
Nature-positive operations should protect ecological quality first and track carbon as one related outcome.
Water
What we do
Connect water use, water quality, stormwater, wastewater, wetlands, and watershed health to operations.
Why it matters
Water decisions affect floodplain function, habitat, resilience, operations, and the Raritan River watershed.
Current initiatives
Water conservation, stormwater management, wastewater management, wetland stewardship, floodplain restoration, and water-quality monitoring.
What others can learn
Water systems can be managed as infrastructure, habitat, and resilience work at the same time.
Waste
What we do
Reduce, reuse, compost, recover materials, and make procurement choices that avoid waste upstream.
Why it matters
Materials decisions show up in events, construction, visitor services, maintenance, and food operations.
Current initiatives
Waste diversion, composting, reuse, purchasing standards, and event operations.
What others can learn
Waste reduction works best when procurement, events, food service, facilities, and agricultural operations are coordinated.

What others can learn
Fleet and equipment planning can reduce emissions while supporting the practical work of the site.
Case studies
What can other campuses learn from Duke Farms?
Each story connects a visible campus project to an operating problem, a sustainability result, and a transferable lesson.
Solar and battery storage as an operating platform
Clean energy transition
- Problem
- Duke Farms needed to reduce greenhouse gas emissions while preparing for future electrified load at the lowest possible cost.
- Approach
- Pair on-site solar with battery storage, distribution upgrades, and energy monitoring.
- Result
- Significant and well quantified progress has been made on Duke Farms' sustainable energy goals; the campus can compare annual generation, hourly service, load matching, and resilience value. See the NSEP.
- What we learned
- Clean electricity works best as an operating platform, not a standalone technology purchase. A high level of solar energy use cannot be achieved without integrated use of stationary electricity storage (batteries).
