In its budget for 2027 Policy and Resources (P&R) has recommended an increase to fuel duty of 4.3%.
However, it faces a number of potential changes, with Deputies Lee Van Katwyk and Rob Curgenven asking deputies to back a freeze in the rise to fuel duty.
While Deputy Neil Inder has put forward two amendments to either freeze the duty rises on diesel or reduce it by 5p per litre.
He suggested it could be paid for by a reduction in the number of civil servants employed by the States of Guernsey.
P&R Treasury Lead Charles Parkinson has said that changes to fuel duty, agreed by deputies earlier in October, would mean a 25% reduction of fuel duty moving forward, alongside the introduction of an annual motor tax.
The Committee for the Environment and Infrastructure (E&I) said these changes to transport taxes would take between 12 and 18 months to implement, so the earliest these changes would come in was 2028, ahead of the introduction of a 3% goods and services tax (GST) in 2029.
