2025 Vehicle-Efficiency Standards Explained: What They Mean for Your Car’s Resale Value

#1 What is the New Vehicle Efficiency Standard (NVES)?

After years of consultation, the Australian Government will introduce a binding fleet-average New Vehicle Efficiency Standard on 1 January 2025.¹ The law sets a cap on the average grams of CO₂ each manufacturer’s newly-sold passenger cars and light commercial vehicles (LCVs) may emit each year. Suppliers that beat their target earn tradeable credits; those that miss must purchase credits or pay a civil penalty.² Credits and penalties will start to accrue from 1 July 2025, giving industry six months to finalise compliance systems.³

#2 Key numbers & timeline at a glance

Year Regulatory milestone Indicative effect*
2025 NVES legislation commences (headline limits set to 2029) Greater model choice in low- and zero-emission vehicles
2026 First annual compliance assessment; statutory review of targets Adjustment of credit/penalty price; early resale signals
2028 Government’s preferred trajectory aligns Australia with current US fleet average New petrol & diesel models must be roughly 20 % more efficient than today⁴
2030 Passenger-car emissions expected to be 60 % lower than pre-NVES and LCVs roughly 50 % lower Running-cost gap between efficient and inefficient vehicles widens

#3 How will the NVES work in practice?

  1. Attribute-based targets – Each brand receives a CO₂ ceiling that varies with the mass in running order of the vehicles it sells, accommodating utes and SUVs while still ratcheting down overall fleet emissions.¹
  2. Credit market – One credit represents 1 g CO₂ /km below target for one vehicle, bankable for three years and tradeable via a government-run registry.²
  3. Penalties – Suppliers whose fleet average exceeds the limit must surrender credits or pay a monetary amount set by regulation.³
  4. Testing cycle – Vehicles are measured under the current NEDC protocol, transitioning to WLTP as Euro 6d noxious-emission standards phase in from December 2025 to July 2028.⁶

#4 Why does the Standard matter to used-car owners?

Although the NVES regulates new vehicles only, it will reshape the second-hand market in several ways:

Impact mechanism What happens Likely resale-value effect
Fuel-cost differential Dept. of Infrastructure modelling estimates $108 billion in cumulative fuel savings to 2050; an average buyer in 2028 saves ≈ $1,000 a year at the pump.⁵ Buyers pay more for cars that cost less to run; efficient ICE, hybrids and EVs should command stronger prices.
Model-mix shift Manufacturers channel more low-emission variants to Australia to avoid penalties.¹ Supply of efficient cars rises; demand for older high-CO₂ models softens, especially post-2027.
Policy signalling Clear government trajectory (review in 2026, five-year rolling targets) reduces uncertainty.³ Markets tend to “price in” future running-cost & compliance risks 12-24 months ahead; early sellers of thirsty vehicles may fare better.
Household budgets ABS CPI weightings show motor-vehicle spending rising amid fuel-price volatility.⁷ Cost-conscious households gravitate to efficient cars, lifting resale for compliance-ready nameplates.

#5 Who are the short-term winners and losers?

Segment 2025-26 outlook 2027-30 outlook Notes
EVs & PHEVs Modest price easing as supply improves; government charging-infrastructure grants to dealerships.⁴ Strong resale; zero-tailpipe-CO₂ vehicles generate multiple credits for first owners.
Hybrids & efficient small ICE Healthy demand; some models may attract “super-credit” multipliers under future rules.² Remain attractive as fuel-price hedge; resale supported.
Large petrol SUVs / V8 utes Possible pre-NVES rush as buyers lock in last batches. Depreciation accelerates once higher running costs and credit penalties become visible in new-car RRPs.
Older—pre-Euro 5—used cars No direct regulation, but higher comparative fuel bills. Gradual loss of desirability unless classic or niche.

#6 Five practical tips to protect (or boost) your car’s resale value

  1. Document real-world fuel economy – Keep a fuel logbook; tangible proof of efficiency reassures prospective buyers.
  2. Stay on top of servicing – A fully-stamped book becomes even more valuable when efficiency is legislatively prized.
  3. Highlight any factory “green tech” – Stop-start systems, mild-hybrid batteries or low-rolling-resistance tyres can differentiate your ad listing.
  4. Consider timing – If you own a high-consumption model you plan to sell anyway, doing so before mid-2026 may yield a stronger price.
  5. Get multiple valuations – Use data points (dealer trade-in, online instant offers, private-sale platforms) to see how the NVES narrative is already influencing offers.

#7 Looking further ahead

  • A statutory review in 2026 could tighten post-2029 targets.³
  • States and territories may begin aligning stamp-duty or registration formulas with CO₂ ratings, amplifying running-cost differences.
  • The ABS transport basket will continue to update weights; in 2024 the Motor vehicles weight rose by 0.26 percentage points on record purchases, signalling enduring consumer interest in newer, more efficient cars.⁷

Bottom line

The 2025 NVES is not a “ban” on any type of car, but it does tilt the economics of motoring decisively toward efficiency. Over the next five years that tilt will flow into the used-car yard. Owners of fuel-efficient or low-emission vehicles can expect firmer resale prices, while sellers of thirsty models may want to move earlier rather than later. Keeping meticulous maintenance records and understanding your vehicle’s official CO₂ rating will help you stay ahead of the curve—and maximise the dollars in your pocket when it’s time to sell.
