FEEBATE SCHEMES

A feebate applies a fee to products or activities above a carbon-performance benchmark and a rebate below it. A familiar example is vehicle policy, where buyers of high-emission cars pay a surcharge and buyers of lower-emission cars receive a bonus. For CDR, the mechanism is credible only within a common product class or producer pool where performance can be compared and improved. This lever therefore focuses on carbon-storing construction products and buildings, and on production systems capable of becoming net-removing. It does not cover fees on unrelated emitters used to subsidise standalone removals, which belong under revenue earmarking, obligations or procurement. Unlike a deposit-refund scheme, the original payer does not recover its own fee by later performing a qualifying act.

Setting the boundary between the fee and the rebate is the central design decision. For example, France’s vehicle bonus-malus, introduced in 2007–08, charged buyers of high-emission cars and rewarded buyers of lower-emission models. Bonus expenditure initially exceeded malus receipts because purchases shifted toward eligible vehicles faster than forecast, producing a substantial first-year deficit. An overly generous boundary can therefore create sustained fiscal costs, while a stringent one weakens the incentive. Governments must also define the covered product class, prevent reclassification, determine how surpluses and deficits are handled, and establish credible rules for measuring removal or stored-carbon content and managing reversals. A CDR-specific scheme should distinguish ordinary emissions reductions from certified removals, potentially using a neutral band and an enhanced removal rebate. Where producers can also receive insetting payments or other support, the rules should disclose combined finance, prevent overcompensation, assign the carbon attribute and specify whether the rebate purchases or retires any resulting unit.

Feebates deliver a continuous price signal rather than a binary standard and can recycle revenue within the market being transformed. The clearest CDR application is the built environment. At material level, products above an embodied-carbon benchmark could pay a fee while comparable products containing verified atmospheric or biogenic carbon receive a rebate. At whole-building level, developers could pay where embodied emissions per square metre exceed a benchmark and receive a rebate for certified carbon stored in long-lived building materials. This could improve the economics of biochar composites, durable bio-based materials and products that permanently bind atmospheric or biogenic CO₂.

Calibration error can produce deficits or dead incentives, while classification gaming can move products or producers onto the favourable side of the schedule. Weak carbon accounting can turn the rebate into a subsidy for paperwork. Agricultural variants could penalise farmers for soil, weather or inherited conditions they cannot control and strengthen buyer power over smaller suppliers. Ambiguous stacking rules can also create overcompensation or duplicate claims. Political changes may separate the two halves, leaving a fee without a rebate or an unfunded rebate without its balancing charge.

Monitoring can compare fee receipts with rebate expenditure, movement across the performance schedule, verified removals and changes in market share. Product declarations, building assessments, facility data and certification registries can be reconciled to test whether rebates correspond to delivered storage. Agricultural variants also require assessment of price pass-through, effects across different farm types and the treatment of weather-related variation. Scheduled evaluations can inform adjustment when fiscal balance, market response, removal delivery or distributional outcomes move outside the intended corridor.

Finance ministries and tax authorities can design the fiscal schedule, while building authorities, sector regulators and certification bodies can define comparable products, benchmarks and removal criteria. Material producers, developers and industrial facilities can test whether the schedule permits realistic investment responses. Agricultural variants require processors, cooperatives, farmers and corporate buyers to clarify contractual control, data access and price pass-through. Consumer, competition and environmental authorities can identify distributional, market-power and integrity risks.

A governance level should be included only where the same actor can impose both sides of the schedule, compare performance across a common pool and give regulated parties a realistic way to improve it. National governments are the natural lead because they control product taxes and rebates, as France’s vehicle bonus-malus demonstrates. Supranational authorities can harmonise schedules across integrated markets, although the EU’s vehicle rules currently provide only a fee-side precedent. Regional/State and City/municipal authorities can operate building-level variants where they control permits, charges and rebates. Corporate/Industry bodies can administer statutory producer schemes, as VANA does for Danish packaging, or contractual supplier pools. Their authority ends outside the covered membership or supply chain, and a bonus-only programme is an insetting incentive rather than a feebate.
