Golf course sustainability statistics show a mixed picture: projected U.S. water use has declined, conservation practices are widespread, and energy use per 18-hole facility has also fallen. At the same time, regional variation, uneven irrigation performance and small-sample outcome studies make broad comparisons difficult.
Key Golf Course Sustainability Statistics
The most useful headline figures span water, management, energy, land and measured outcomes:
- In 2013, U.S. golf courses used a projected 1.859 million acre-feet of water per year, down from 2.379 million acre-feet in 2005.

Golf Course Sustainability Statistics: Water Use Trends and Regional Variation
The national water trend is downward, but the available measures combine facility counts, acreage and management changes. The peer-reviewed water-use study reports a projected 1.859 million acre-feet per year in 2013, compared with 2.379 million in 2005, a 21.8% decline; it cautions that the change reflects both management and facility or acreage changes. (Documenting Trends in Water Use and Conservation Practices on U.S. Golf Courses)
Regional medians show why a national total does not describe every course:
| 2013 region | Median annual water use | Population and unit |
|---|---|---|
| Southwest | 3.87 acre-feet/acre | U.S. 18-hole courses |
| Transition zone | 0.60 acre-feet/acre | U.S. 18-hole courses |
The same survey found course-level use ranging from no irrigation to more than 9 acre-feet per acre per year. These are regional medians and a course-level range, not a national average. (Documenting Trends in Water Use and Conservation Practices on U.S. Golf Courses)
The facility base also changed. The number of U.S. golf facilities declined by 666, from 16,052 in 2005 to 15,386 in 2013, and an estimated 3,176 courses voluntarily reduced acreage between 2009 and 2013, compared with 1,316 between 2001 and 2005. (Water Use and Conservation Practices on U.S. Golf Courses)
Reduced irrigated acreage totaled 14,430 acres and was associated with a reported 43,910 acre-feet per year of water reduction from 2009 to 2013. The association includes acreage-reduction calculations rather than an isolated causal experiment. (Water Use and Conservation Practices on U.S. Golf Courses)
The later GCSAA survey release reports a 2024 projected applied-water total of 1.63 million acre-feet, 3.2% below 2020 and 31% below 2005. This is a national projection from a later survey, not a direct meter total. (Water Use and Conservation Practices on U.S. Golf Courses)
For 2024, reported irrigation sources were wells at 32%, lakes and ponds at 27%, and recycled water at 19%. The shares may not sum to 100% because other sources are omitted. (Water Use and Conservation Practices on U.S. Golf Courses)
Golf Course Water Conservation Statistics and Management Practices
Reported conservation practices became more common between 2005 and 2013. The figures are self-reported facility adoption rates, not direct measurements of water saved.
- Wetting-agent use increased from 88% to 94% of U.S. facilities.
- Hand watering increased from 72% to 77% of U.S. facilities.
- Keeping turf drier than in the past increased from 62% to 74% of U.S. facilities.
- Mulching landscape beds increased from 43% to 48% of U.S. facilities.
- Adjusting fertilizer practices increased from 42% to 52% of U.S. facilities.
- Use of soil amendments increased from 29% to 40% of U.S. facilities.
- Drip irrigation for landscape plants increased from 13% to 16%; this measure does not cover all irrigated turf.
Several measures were recorded only in 2013, so they do not establish a trend. Irrigation scheduling was reported by 50% of facilities, hand-held moisture sensors were used by 33%, and increasing no-mow acreage was reported by 46%. (Water Use and Conservation Practices on U.S. Golf Courses)
Regional practice rates differed materially. In the Southwest, wetting-agent use was 91% in 2013, up from 76% in 2005; in the Pacific, drip irrigation for landscape plants was 27% in 2013 versus 18% in 2005; and in the Southeast, mulching landscape beds was 64% versus 59%.
Wetting-agent use reached 98% in the Upper West/Mountain region in 2013. (Water Use and Conservation Practices on U.S. Golf Courses)
Golf Course Sustainability Data for Irrigation Efficiency, Plans and Monitoring
The 2020 Phase III survey measured irrigation performance among facilities that conducted audits. Average distribution uniformity was 80%, but 100% is not considered realistic and non-auditing facilities are excluded.
Regional audited-course results ranged from 93% in the Southwest to 63% in the Pacific. (Water Use and Management Practices on U.S. Golf Courses: Phase III)
| Audited course feature | Average distribution uniformity, 2020 | Scope |
|---|---|---|
| Fairways | 54% | U.S. audited facilities |
| Tees | 45.4% | U.S. audited facilities |
| Greens | 61% | U.S. audited facilities |
These feature-level results should not be treated as whole-course averages. The same survey found that 23% of U.S. facilities had drought plans in 2020, although the presence of a written plan does not measure implementation quality. (Water Use and Management Practices on U.S. Golf Courses: Phase III)
Superintendents reported golfers as consistently receptive to reduced-applied-water appearance changes at rates from 75% to 91% across U.S. regions. This is reported receptiveness, not a direct golfer poll. (Water Use and Management Practices on U.S. Golf Courses: Phase III)
Monitoring rates also depend on the denominator. Among facilities testing surface water, annual testing was reported by at least 48% across regions; surface-water testing prevalence ranged from 26% in the North Central region to 51% in the Southwest.
Among facilities with groundwater wells, groundwater testing ranged from 24% in the Pacific to 51% in the Southwest. (Water Use and Management Practices on U.S. Golf Courses: Phase III)
Golf Course Energy Use and Greenhouse-Gas Emissions Statistics
Mean annual energy use per 18-hole U.S. facility fell from 2,623 to 2,405 MMBtu between 2008 and 2015, an 8.3% decrease. Overall golf-course-industry energy use fell 7.8%; the report’s decomposition attributed 61% of that change to fewer facilities and 39% to behavioral energy changes. (Energy Use and Environmental Practices on U.S. Golf Courses)
The fuel mix moved in different directions. Electricity use at individual 18-hole facilities decreased 31.4% from 2008 to 2015, while diesel-fuel use increased 2.2%; irrigation-pumping electricity did not change.
These are facility-level use results, not a total-carbon calculation. (Energy Use and Environmental Practices on U.S. Golf Courses)
A separate three-year model-based study of Northern U.S. courses reported the following energy and emissions estimates:
| Modeled measure | Mean result | Study scope |
|---|---|---|
| Scope 1 energy | 24 GJ/ha/year | 14 Northern U.S. courses |
| Scope 2 energy | 7 GJ/ha/year | Seven courses |
| Scope 3 energy | 40 GJ/ha/year | Seven courses |
| All-scope energy | 72 GJ/ha/year | Four courses with all-scope totals |
| All-scope emissions | 4,277 kg CO2e/ha/year | Four courses with all-scope totals |
The same study estimated mean Scope 1 emissions at 1,599 kg CO2e/ha/year, Scope 2 at 1,012, and Scope 3 at 1,847. Fuel and electricity use accounted for 63% of modeled greenhouse-gas emissions, and the small regional samples should not be generalized to a national golf-course average. (Estimated energy use and greenhouse gas emissions associated with golf course turfgrass maintenance in the Northern USA)
Golf Course Land, Habitat and Environmental-Stewardship Statistics
The U.S. property-profile comparison found that facilities participating in an environmental-stewardship program averaged 160 acres, compared with 150 acres for non-participants. Participating facilities averaged 63% maintained turfgrass and 19% natural, native or non-mowed area, versus 69% and 15% respectively for non-participants. (Property Profile and Environmental Stewardship of U.S. Golf Facilities)
Other reported property shares were similar but not identical:
| Property category | Participating facilities | Non-participating facilities |
|---|---|---|
| Water bodies | 8% of acreage | 7% |
| Bunkers | 4% | 3% |
| Buildings/features | 3% | 3% |
| Parking lots | 3% | 3% |
These are rounded property-profile comparisons, not a national land-cover census. The natural, native and non-mowed category is defined by the report and combines those areas. (Property Profile and Environmental Stewardship of U.S. Golf Facilities)
Participation also varied by facility characteristics. Environmental-program participation was 29% at 18-hole facilities and 36% at private facilities; it was 18% at facilities with maintenance budgets below $500,000 and 47% at facilities above $1 million.
GCSAA members reported 32% participation, compared with 17% among non-members. These are observational comparisons and do not establish causation. (Property Profile and Environmental Stewardship of U.S. Golf Facilities)
Golf Course Sustainability Outcomes: Water Efficiency and Ecosystem Services
Water-use efficiency studies help separate adoption of practices from modeled outcomes. A 2025 study of 71 U.S. golf courses reported mean actual-water-use-to-modeled-requirement ratios of 1.16 with the USGA model, 1.25 with the Tipping-Bucket model and 1.17 with Agro-IBIS.
Ratios above 1 indicate use above the modeled requirement, and results depend on model specification. (Quantifying golf course water use efficiency using three water balance models of varying complexity)
The study interpreted the three means as courses using 16% to 25% more water than predicted on average. Its coefficients of variation were at least 0.45 for all three scores, indicating substantial heterogeneity without identifying its causes; the abstract does not state the study period. (Quantifying golf course water use efficiency using three water balance models of varying complexity)
Ecosystem-service valuation provides a different outcome lens. A case study using a 2013 valuation basis estimated net ecosystem-service values of 51.58×10^4 yuan/ha/year for a links course and 42.60×10^4 yuan/ha/year for a parkland course in Beijing, China; the paper noted an exchange basis of 6.19 yuan per U.S. dollar in 2013. (Using assessment of net ecosystem services to promote sustainability of golf course in China)
More than 95% of the estimated value in that Beijing case came from recreation, ecosystem goods and flood storage. It is a two-course case-study valuation, not a global golf-course result. (Using assessment of net ecosystem services to promote sustainability of golf course in China)
