A good sustainable travel policy puts virtual meetings first, applies a clear hierarchy of travel modes, and sets measurable targets with named owners and review dates. It applies to official business travel across an organisation, aiming to cut emissions while protecting safety and value for money. The rest of this guide walks through scope, decision-making, measurement and the practical steps needed to put that approach into daily use.
TL;DR:
Virtual meetings should be prioritized over physical travel whenever possible to significantly reduce emissions.
Travel approvals must follow a hierarchy that considers necessity, mode impact, and safety, with escalation procedures embedded into systems.
Organizations should set clear, measurable targets with a defined baseline, responsible owner, and review schedule, disaggregating emissions by mode and purpose.
Procurement practices need to verify suppliers’ fleet emissions, safety accreditation, and accessibility features before contracting.
Accurate measurement and regular review of travel data are essential to ensure transparency, accountability, and continuous improvement of sustainable travel policies.

Who the policy covers and which journeys count
A policy only works when it states clearly who must follow it and which journeys are in scope. Ambiguity here is where most institutional travel policies lose credibility, because staff and contractors default to old habits when the boundaries are not spelled out.
The University of Edinburgh’s sustainable travel policy treats this as a foundation, defining coverage before addressing mode choice or targets. A well-scoped policy typically includes:
-
Staff, contractors, students and third parties travelling on official business, regardless of seniority.
-
Local, national and international journeys, including fieldwork, conferences and site visits.
-
Funding source clauses that apply the policy even when a grant, sponsor or external partner is paying.
-
Cross-references to health and safety, procurement and insurance policies, so travel decisions do not sit in isolation from wider governance.
Scope should be reviewed whenever the organisation takes on new contract types, such as fieldwork partnerships or overseas campuses, since these often introduce journeys the original drafting never anticipated.
The travel hierarchy: avoid, reduce, shift, improve
The backbone of any credible policy is a hierarchy that ranks options by impact rather than habit. Imperial College London’s approach to sustainable travel places virtual and digital alternatives first, with physical travel considered only once that option has genuinely been ruled out.
A practical mode order looks like this:
-
Virtual or digital alternative such as video conferencing, used whenever the purpose of the trip can be met remotely.
-
Active travel, walking or cycling, for short local journeys.
-
Public transport, rail, bus or ferry, for national and regional trips.
-
Shared, electric or hybrid vehicles, where public transport is impractical.
-
Private car, reserved for journeys with no reasonable shared alternative.
-
Air travel, treated as a last resort and subject to justification.
Safety and accessibility always take precedence over hierarchy position: a wheelchair user or a lone traveller at night may need a private vehicle even where cycling would otherwise rank higher. The strongest policies also apply a ‘quality over quantity’ principle, prioritising trips with a clear, demonstrable benefit rather than judging trips purely by their carbon intensity.
Pro Tip: Write exceptions into the policy itself, rather than leaving them to informal manager discretion, so wellbeing and safety cases are handled consistently.
How approvals should work: decision trees and delegation
A hierarchy only changes behaviour if it is backed by an approval process people actually have to use. The recommended flow asks four questions in order: is the travel necessary, is a virtual alternative viable, what is the preferred mode under the hierarchy, and who needs to approve it.
Delegated authority should scale with distance and cost, not just budget size:
-
Local and domestic travel can usually be approved by a line manager with a brief justification.
-
International travel should require sign-off from a senior budget holder, plus a documented risk assessment.
-
Air travel specifically often needs an additional sustainability check, confirming that rail or virtual options were genuinely considered.
-
Exceptions should be logged in a standard template capturing the reason, the higher-carbon mode chosen and the approver’s name.
Both Edinburgh and King’s College London embed these approvals into finance systems, so a booking cannot proceed without the sign-off attached. This lets sustainability considerations override a cheaper but higher-carbon option where the policy explicitly allows it, rather than leaving cost as the only deciding factor.
Setting targets and reporting travel emissions properly
Targets only carry weight when they have a baseline, a boundary, an owner and a date. Imperial’s policy sets a target of a 25% reduction in air-travel carbon per person by 2026 against a 2017-18 baseline, giving a concrete example of what a timebound commitment looks like in practice.
For organisations with formal reporting duties, official business travel sits under Scope 3, Category 6. Government sustainability reporting guidance recommends disaggregating this figure by mode and purpose, rather than publishing a single travel total that hides where emissions actually come from.
The 2026 UK government conversion factors provide the official emissions values for rail, road, air and other transport modes, and any calculation should record which factor year and method was used, since figures are updated annually and are not directly comparable across years.
Building credible measurement means:
-
Setting a baseline year before announcing any reduction target.
-
Naming a responsible owner for tracking and reporting.
-
Reviewing targets on a fixed date, not an open-ended “ongoing” basis.
-
Recording the conversion-factor year alongside every reported figure.
Turning the policy into daily operations
Written principles achieve little unless they are embedded in the systems people use to book and claim travel. Roles need to be explicit: the traveller requests, the authoriser approves against the hierarchy, the travel manager coordinates bookings, and finance checks the approval trail before reimbursement.
-
Route bookings through a preferred channel or travel management company, so data on mode, distance and cost is captured automatically rather than reconstructed later.
-
Add sustainability clauses to procurement briefs, requiring suppliers to disclose fleet emissions and safety accreditation.
-
Publish clear traveller guidance, covering risk-assessment templates, insurance steps and expected booking behaviour.
-
Offer basic training so approvers understand the hierarchy well enough to challenge, not just rubber-stamp, requests.
Practitioner guidance on embedding sustainability into governance consistently finds that policies with named roles and escalation routes are the ones that actually get followed.
Practical clauses worth copying into your own policy
Some of the most effective policy language is also the simplest. Setting a time threshold, for instance a rule preferring rail over air for journeys under a defined number of hours, removes debate from individual bookings and gives travellers and approvers a shared reference point.
-
Prefer rail for journeys under the institution’s defined threshold, rather than leaving the choice to personal preference.
-
Choose non-stop flights by default when flying is unavoidable, since connections add both emissions and travel time.
-
Set economy class as the default cabin, with upgrades requiring separate justification.
-
Support active travel through cycle-to-work schemes and flexible hours that let staff avoid peak congestion.
-
Specify group and accessible transport requirements in procurement briefs, covering fleet emissions, wheelchair accessibility and safety accreditation.
Pro Tip: Ask any coach or minibus supplier for their safety accreditation and accessibility provision in writing before shortlisting them, not after the contract is signed.
Keeping the policy honest through monitoring and review
A policy is only as good as the data behind it. Organisations should collect activity-level records by mode, distance and passenger numbers, and note which conversion-factor year applied to each calculation, since mixing years produces misleading comparisons.
A practical cadence includes biannual reporting on travel emissions, alongside a fixed schedule for policy review and periodic audits of exception logs. Findings from these reviews should feed directly back into procurement specifications, training content and future targets, closing the loop between measurement and action rather than treating reporting as an end in itself.

What a specialist transport supplier brings to policy delivery
Procurement briefs for group travel can ask suppliers for specific, checkable evidence rather than vague sustainability claims. Cozy Travel, for example, operates the UK’s first hybrid coach, holds the highest 6-star BUSK safety rating, and has decades of experience delivering home-to-school and corporate contracts.
-
Ask for evidence of hybrid or ULEV fleet capacity, not just a general sustainability statement.
-
Request current BUSK accreditation or an equivalent safety rating as a shortlisting condition.
-
Confirm accessible, wheelchair-adapted vehicle availability where the contract requires it.
-
Check for demonstrable experience with comparable contracts, such as schools or corporate clients.
What to get right first
Start with governance and measurement, not offsets. Low-friction rules such as virtual-first meetings, economy class by default and a single preferred booking channel build credibility fast and cost little to enforce. Save ambitious targets for once the basics are working.

FAQ
What are some examples of sustainable travel policies?
Institutional examples include Imperial College London’s policy, which sets a timebound air-travel reduction target, and the University of Edinburgh’s policy, which applies the avoid-reduce-shift hierarchy alongside mandatory risk assessments. Both combine measurable targets with clear approval procedures rather than relying on general commitments.
What is meant by sustainable travel?
Sustainable travel means choosing the mode and frequency of journeys to reduce environmental impact while still meeting the underlying need for the trip. In an organisational context, this typically follows a hierarchy that favours virtual alternatives, active travel and public transport ahead of private cars and air travel.
What are the three P’s of sustainable tourism?
Sustainable tourism is often described using a people, planet and profit framework, balancing social impact, environmental protection and economic viability. Definitions vary by source, so organisations should check which framework a specific standard or report is using before citing it.
What are some examples of sustainable travel destinations?
This guide focuses on organisational travel policy rather than destination selection, so it does not cover specific destinations. Organisations wanting destination-level guidance should consult dedicated sustainable tourism resources rather than a travel policy framework.
How do conversion factors affect sustainable travel reporting?
The UK government publishes annual greenhouse gas conversion factors used to calculate emissions from travel by mode. Because factors are updated each year, organisations should record which year’s factors they used to keep reported figures comparable over time.
