Carbon Emissions Dashboard
Results shown here are for Duke Farms, a center of the Doris Duke Foundation. This dashboard tracks progress toward the Natural Systems Energy Plan (NSEP) goals: 100% clean electricity and an 80% reduction in greenhouse gas emissions within the current dashboard emissions boundary. That boundary covers Scope 1, Scope 2, and included Scope 3 Category 7 employee commuting; broader Scope 3 inventory work is underway and targeted for completion at the end of 2026.
Showing 2026 (year to date). This view includes 290 records; the carbon reduction target uses baseline year 2023.
Current-year data is labeled year-to-date until all annual utility and fuel records are loaded.
Duke Farms clean electricity, energy use, and emissions progress
Duke Farms uses 2023 as the official NSEP implementation base year for tracking future decarbonization progress. Historical emissions reductions are also reported relative to the 2006 reference year to align with New Jersey climate policy.
100% clean electricity on an annual basis
116.1% matched
Physical annual matching for 2026 (year to date): 1,520 MWh of on-site solar generation compared with 1,310 MWh of campus electricity use. This is an energy-flow view, separate from REC/SREC ownership.
80% emissions reduction from 2023
YTD only
2026 (year to date): 865.2 metric tons CO2e recorded so far; annual progress against the 2023 baseline is not finalized.
Year-to-date emissions vs same period last year
1.2% lower
2026 (year to date): 865.2 metric tons CO2e compared with 875.7 metric tons CO2e through Aug 2025. This avoids comparing a partial year with a full historical year.
Scope 1
Direct campus fuels: natural gas, heating oil, propane, gasoline, and diesel.
Scope 2
Included campus electricity use valued with the grid emissions factor; on-site solar matching and REC/SREC ownership are tracked separately.
Scope 3, Category 7
Employee commuting fuel and charging estimates included in the current dashboard boundary.
Broader Scope 3
Broader inventory work is underway and targeted for completion by the end of 2026.
Gross emissions reductions and verified carbon removals are reported separately, with the long-term goal of reaching net-zero and ultimately net-negative emissions.
Goal 1: 100% Clean Electricity
This goal compares on-site solar electricity generated with electricity used across campus buildings and public charging stations on a net annual matching basis. It is separate from carbon-accounting claims tied to REC/SREC ownership. Year-to-date progress.

Monthly year-to-date view for 2026 (year to date)
Year-to-date progress
This value shows progress so far in 2026. It will change as more monthly data is added.
On-site solar generation
1,520 MWh
Original solar panels: 432 MWh
Newer solar panels: 1,088 MWh
Campus electricity use
1,310 MWh
Main campus buildings: 1,196 MWh
Public charging stations: 62.5 MWh
Other buildings: 51.1 MWh
Duke Farms generates enough on-site solar electricity to match its annual electricity use in strong years. The associated REC/SREC ownership is tracked separately for carbon-accounting claims, so Goal 2 does not treat the physical match as carbon-free electricity.

Hourly matching profile
MWh serving site load
This interval profile shows clean electricity serving site load. Solar exported to the grid is not included, so direct solar is capped at hourly load. Hourly matching is an operational view that helps show reduced reliance on grid-supplied electricity.
Battery-supported solar use by hour
97.3% evening/overnight
Bars show solar energy served from the battery. The green line shows real-time solar serving load. Evening and overnight battery bars indicate stored solar helping serve load when real-time production is low.

Physical / engineering ledger
Actual energy-flow fields are shown where the current exports support them.
2026 (year to date)
Solar generated on-site
1,520 MWh
Annual production from the on-site arrays; carbon-accounting claims depend on REC/SREC ownership.
Solar consumed on-site
666 MWh
Current export can report this only for selected-year interval rows.
Grid electricity imported
434 MWh
Imported grid electricity from selected-year interval rows.
Estimated avoided grid emissions
216.3 metric tons CO2e
Engineering estimate only; REC/SREC ownership is tracked separately for carbon-accounting claims.
Goal 2: 80% Lower Emissions from energy use (Scope 1 and Scope 2)
This year-to-date view includes Scope 1, Scope 2, and Category 7 Scope 3 employee commuting recorded so far. Annual goal progress will be finalized after 2026 is complete. Broader inventory work for Scope 3 is underway and targeted for completion at the end of 2026.
