Corporate travel emissions are no longer just a line in an ESG report. For many organisations in New Zealand and Australia, they are one of the most visible and practical Scope 3 levers to manage. The challenge is turning scattered travel data into emissions numbers that are accurate, consistent and ready for scrutiny from boards, investors and auditors.

In this article, we look at how corporate travel management data, when integrated through tools such as Zeno, Orbit Enterprise and Orbit Intelligence, can move your organisation from rough estimates in spreadsheets to operational, audit-ready travel emissions accounting that links directly to ESG reporting, science-based targets and everyday travel decisions.

Why Scope 3 travel emissions are under pressure

Business travel usually sits in Scope 3, often in Category 6 business travel and sometimes overlapping with employee commuting for longer assignments. For sectors like healthcare, energy, pharmaceuticals, media, universities, professional services and government, this category is often material because teams travel regularly across regions and time zones, client/patient/project/research needs require face-to-face work, and senior leaders travel frequently in ways that set behavioural norms.

At the same time, climate-related financial disclosures are tightening. Investors, funders and boards now expect consistent reporting of Scope 3 travel emissions, clear links between emissions and organisational net zero commitments, and evidence that travel policies and supplier choices reflect climate goals.

Many organisations are still relying on finance data or expense reports to estimate travel emissions, and that often creates practical and audit challenges, including:

• Incomplete data when travellers book outside approved channels

• Mixed emissions factors from different tools or suppliers

• Manual spreadsheets with no clear audit trail

This is where corporate travel management can shift from pure logistics to a strategic lever. Instead of only reporting emissions after the fact, organisations can use policy, approval workflows and supplier choices to shape emissions outcomes as travel decisions are made.

Building an audit-ready emissions foundation

Reliable travel emissions accounting starts with the data foundation. That means more than just having a record of trips. You need complete booking data for air, hotel and ground transport, de-duplication of segments and consistent traveller profiles, and clear links between each booking, its cost and its emissions output.

A travel management company can centralise this by using integrated tools such as:

• Zeno and Amadeus to bring bookings into one environment

• Orbit Enterprise to control policy, approvals and workflow

• Orbit Intelligence to consolidate reporting and analytics

For sustainability and finance teams, transparent methodology is as important as the numbers themselves. This requires clear documentation of the emissions factors used and how often they are updated, how calculations are handled (including any aviation uplift such as radiative forcing), how cabin classes, fare types and route differences are treated, and how off-channel or card-only spend is estimated or flagged.

Audit readiness is strengthened when you have:

• Version-controlled reports with timestamps and methodology notes

• Clear data lineage from original booking through to final emissions totals

• Regular governance meetings across travel, finance, procurement and sustainability teams to review data quality and assumptions

Linking travel data to SBTi-aligned targets and budgets

Once your travel data is complete and consistent, you can translate historical emissions into a science-based baseline. Using corporate travel management data, you can then model emissions reduction pathways that align with Science Based Targets initiative guidance on business travel.

This usually starts with segmentation, so you can understand where emissions sit and where levers are most practical. For example, emissions can be viewed by:

• Route or corridor

• Region or office

• Business unit or project

• Traveller cohort or trip purpose

That visibility helps you identify practical levers to reduce emissions while protecting business outcomes, such as:

• Consolidating trips to reduce frequency while maintaining outcomes

• Switching to virtual or hybrid options for certain meeting types

• Considering rail or lower-emission options where they are realistic

• Adjusting cabin class policies on specific routes

Integrating emissions into budgeting cycles is a logical next step. Outputs from Orbit Intelligence, combined with finance data, can support:

• Carbon budgets alongside financial budgets

• Approval thresholds that consider both cost and emissions

• Forecasts that show how planned travel will track against SBTi-aligned pathways

Shared dashboards mean travel managers, procurement teams, EAs and senior leaders can see the same numbers. This supports consistent decision-making and aligned reporting in ESG disclosures.

Integrating TMC data into ESG and sector reporting

To support ESG reporting, travel emissions data needs to sit alongside other Scope 1, 2 and 3 categories in your existing systems. Structured exports and APIs from your travel management company can help feed:

• Enterprise ESG platforms

• Corporate data warehouses

• Finance and reporting tools already in use

Sector needs can differ. Universities often need to balance academic freedom, research impact and travel expectations. Healthcare and pharmaceuticals frequently have critical clinical, field and conference travel that must continue. Energy and infrastructure organisations may have travel-intensive project work and site visits.

Public sector organisations using All-of-Government travel programmes need to align AoG travel data with internal ESG metrics and public accountability requirements. This calls for:

• Agreed data owners and definitions

• Regular update cycles that align with reporting timetables

• Validation checks so that numbers in annual, integrated and sustainability reports are consistent and defensible over time

Turning emissions accounting into better travel decisions

The real value comes when emissions data changes choices at the point of booking, not just at year-end. That means embedding insights into day-to-day corporate travel management through:

• Approval workflows in Orbit Enterprise that flag high-emissions options

• Traveller messaging that highlights preferred low-emission choices

• Choice architecture in Zeno, so lower-emissions routes and cabins are easy to select

Dashboards in Orbit Enterprise and Orbit Intelligence can show:

• Emissions alongside fare cost and flexibility

• The impact of choosing one routing or cabin over another

• Trends by team or project that help leaders engage with their travellers

Traveller engagement works best when the metrics are simple and actionable. In practice, this often means focusing on measures such as emissions per trip, per project or per person over a period, so travellers and leaders can quickly understand what to change.

Supplier strategy is another key lever. Consolidated emissions data can inform:

• Airline and accommodation RFPs

• Preferred supplier programmes and route deals

• Conversations about sustainable aviation fuel options or lower-impact accommodation choices where available

Next steps to operationalise travel emissions with confidence

A structured roadmap helps bring all of this together. Many organisations start by:

• Assessing current travel data quality and gaps

• Aligning internal stakeholders across travel, finance, procurement and sustainability

• Confirming Scope 3 and SBTi expectations for business travel

• Co-designing an operating model with their travel management company, including roles, processes and reporting cycles

Trialling the approach with a single business unit, division or region can be useful because it provides a controlled way to prove the methodology and improve the operating model before scaling. This allows you to:

• Validate emissions outputs against internal expectations

• Refine assumptions and factors where needed

• Test how dashboards and approvals influence real booking behaviour

By combining integrated technology, consistent reporting and strong account management, a travel management company can help you turn travel emissions accounting into a practical, repeatable part of your broader ESG, budgeting and duty of care programme.
