Want to win more contracts? Green fleet certification gives you a documented competitive advantage. Certified fleets report 10-15% higher win rates on RFPs that evaluate sustainability—and with corporate clients and government agencies increasingly requiring ESG proof, that advantage is growing. The best part? NAFA's Green Fleet Award is free to apply for, and with proper CMMS documentation, you can complete your application in under 5 hours.
What Is Green Fleet Certification?
Green fleet certification is third-party validation that your fleet meets established sustainability standards. Unlike self-reported ESG claims (which 68% of procurement managers say they distrust), certification provides verified proof of your environmental practices—the kind of proof that wins contracts.
The most recognized certification in North America is the NAFA Green Fleet Award, administered by the National Association of Fleet Administrators. Other programs include state-level certifications (Tennessee Green Fleets, Louisiana Green Fleets, Empire Green Fleets) and industry-specific programs like EPA SmartWay for freight carriers.
Green Fleet Certification Programs Compared
Does Green Fleet Certification Actually Help Win Contracts?
Yes—and the data backs it up. Here's why certification translates directly to competitive advantage:
RFP Scoring Points
Many government and corporate RFPs now allocate 5-15% of scoring to sustainability criteria. Certification provides documented proof that scores maximum points in this category—often the difference between winning and losing competitive bids.
Procurement Shortlists
Procurement teams use certifications to filter vendor lists before detailed evaluation. Without certification, you may not even reach the evaluation stage on sustainability-conscious contracts.
Client Retention
Existing clients face their own ESG reporting requirements. Your certification helps them document Scope 3 emissions from their supply chain—making you a preferred vendor they're less likely to replace.
Premium Pricing
Certified fleets can justify premium rates. When clients need sustainability documentation for their own reporting, they'll pay more for vendors who can provide verified metrics.
Real Example: How Certification Won a Major Contract
A charter bus company in the Northeast achieved TRUE (Total Resource Use and Efficiency) certification for their depot operations. Result? They won 3 major corporate contracts specifically citing their sustainability credentials as the deciding factor. The certification cost them nothing but 8 hours of documentation time—the contracts were worth $2.1M annually.

Getting Started Book a DemoWhat Are the NAFA Green Fleet Award Requirements?
NAFA evaluates fleets across six core criteria. You don't need to excel in all areas—the application lets you highlight your strengths while showing progress in developing areas.
Percentage of alternative fuel vehicles (EVs, hybrids, CNG, propane, biodiesel) in your fleet. NAFA looks for both current composition and year-over-year improvement trends.
Data needed: Vehicle inventory by fuel type, AFV percentage, acquisition plans
Measurable reductions in greenhouse gases (CO2), nitrogen oxides (NOx), and particulate matter (PM2.5). Judges want specific numbers, not vague claims.
Data needed: Baseline emissions, current emissions, reduction percentages, calculation methodology
Driver training and behavior programs that reduce fuel consumption. Includes eco-driving training, idle reduction policies, and telematics-based coaching.
Data needed: Training completion rates, idle time reduction, MPG improvements, driver scorecards
Sustainability upgrades to maintenance facilities, depots, and charging infrastructure. Solar installations, LED lighting, and waste reduction programs count here.
Data needed: Facility energy usage, renewable installations, waste diversion rates
Policies for purchasing sustainable products, from recycled parts to eco-friendly fluids. Also includes vendor sustainability requirements and lifecycle considerations.
Data needed: Procurement policies, sustainable vendor list, recycled material usage
Policies that reduce total fleet size, vehicle utilization optimization, and fuel consumption per mile. Right-sizing initiatives and route optimization count here.
Data needed: Fleet size trends, utilization rates, fuel consumption per mile/passenger

The biggest barrier to green fleet certification isn't the criteria—it's pulling together the documentation. Here's exactly what you need and how CMMS makes it easier:
Required Documentation Checklist
How CMMS Automates Certification Documentation
Fuel Tracking by Type
Automatically categorizes fuel purchases by type (diesel, gasoline, CNG, electric, biodiesel) and generates annual summaries in gallons and GGE.
Emissions Calculator
Uses EPA emission factors to calculate CO2, NOx, and PM2.5 from your fuel data. No manual calculations or spreadsheets required.
Fleet Composition Reports
Tracks alternative fuel vehicle percentage over time, showing acquisition trends and retirement schedules that demonstrate commitment.
Efficiency Metrics
MPG by vehicle, idle time percentages, and fuel cost per mile—all the data points judges want to see for green driving programs.
What Award Categories Can You Win?
NAFA recognizes fleets across multiple categories, so even if you're not the largest or greenest fleet, you can earn meaningful recognition:
Top Green Fleet
The highest honor, awarded to the fleet with the most comprehensive and impactful sustainability program. 2024 winner: City of New York DCAS.
Best Fuel Technology Integration

Frequently Asked Questions
What is green fleet certification?
Green fleet certification is third-party recognition that validates a fleet's sustainability efforts. The most recognized program is NAFA's Green Fleet Award, which evaluates alternative fuel use, fleet composition, emissions reduction, green technology adoption, and eco-driving programs. Certification is free to apply for and open to both government and commercial fleets in North America.
How do I apply for NAFA Green Fleet certification?
Applications open annually in spring with a July deadline. The process is free and fully online at nafa.org/awards/green-fleet-awards. You'll need to document fleet composition, alternative fuel usage, emissions data, green initiatives, and sustainability programs. Winners are announced at the Sustainable Fleet Technology Conference in August.
Does green fleet certification help win contracts?
Yes. Certified green fleets report 10-15% higher win rates on RFPs where sustainability is evaluated. Many government contracts now require ESG documentation, and corporate clients increasingly prioritize vendors with verified sustainability credentials. Certification provides third-party proof that differentiates your bid from competitors.
What are the NAFA Green Fleet Award criteria?
NAFA evaluates six main areas: fleet composition and alternative fuel vehicles, environmental benefits and emissions reduction, green driving programs, facilities improvements, green procurement initiatives, and policies to reduce fleet size and fuel consumption. Fleets are judged on originality, program success, and measurable energy reduction.
How much does green fleet certification cost?
The NAFA Green Fleet Award application is completely free. There are no entry fees, membership requirements, or hidden costs. State-level green fleet programs (Tennessee, Louisiana, New York) are also free. The only investment is time to compile documentation—typically 4-8 hours with proper CMMS data.
What documentation do I need for green fleet certification?
Required documentation includes total annual fuel use by fuel type, vehicle inventory with alternative fuel designations, emissions calculations (CO2, NOx, PM2.5), green initiative descriptions, and measurable results. CMMS platforms can auto-generate most of this data, reducing application time from 20+ hours to under 5 hours.
Are there different levels of green fleet certification?
Yes. State programs like Tennessee Green Fleets use a three-star system based on actual performance. NAFA awards include Top Green Fleet, Best Fuel Technology Integration, Rookie of the Year, and category-specific recognition. Higher certification levels demonstrate greater commitment and can further strengthen contract bids.
How long does green fleet certification last?
NAFA Green Fleet Awards are annual—you reapply each year to maintain recognition. State programs like Louisiana require re-certification every 3 years. Annual certification keeps your credentials current and demonstrates ongoing commitment rather than one-time effort, which is more compelling to contract evaluators.
