The landscape of transport carbon reporting is changing fast in both New Zealand (NZ) and Australia, driven by both global commitments to net-zero emissions and domestic regulatory frameworks. For businesses in the transport and logistics sector, the introduction of mandatory climate reporting brings with it a series of new responsibilities and challenges. But it's not just about compliance; the transition to more transparent, sustainable practices is also an opportunity to drive innovation, improve efficiencies, and even gain a competitive edge. Whether you're a fleet manager in Auckland or a logistics operator in Sydney, understanding and adapting to these changes is crucial for your future success.
Platforms like Cario’s Freight Management System (FMS), combined with the operational expertise of Freight People as a brokerage partner, enable businesses to capture, analyse, and act on transport emissions data in real time—turning carbon reporting from a compliance burden into a strategic advantage.
This guide will walk you through the key aspects of transport carbon reporting in NZ and Australia, including the regulatory regimes, emission scopes, and practical strategies to meet the new standards, ensuring you stay ahead of the curve and contribute to a more sustainable future.
In both New Zealand and Australia, the government is placing increasing pressure on businesses to disclose their carbon emissions. While the end goal is aligned—helping countries meet their net-zero emissions targets—the way that each country approaches this task differs significantly. These differences can impact how transport businesses report their emissions, especially in relation to Scope 1, 2, and 3 emissions, which cover direct emissions, energy-related emissions, and emissions across the supply chain, respectively.
Australia is gearing up for its mandatory Climate-Related Financial Disclosures (CRFD) regime, which will come into effect in 2025. The Australian Accounting Standards Board (AASB) S2 and its alignment with the International Financial Reporting Standards (IFRS S2) will be pivotal for Australian businesses. The transition to full compliance will be phased over several years, and it will directly impact logistics and transport businesses that operate at scale.
For example, Group 1 entities, such as large transport firms and those subject to National Greenhouse and Energy Reporting (NGER), will need to start reporting in January 2025. These are the big players—the companies that own fleets, manage warehouses, and run large-scale distribution networks. However, smaller businesses won’t be left behind for too long. Group 2 entities—those with assets of more than $5 billion—must comply by July 2026. By July 2027, even smaller operations will face reporting requirements if their consolidated assets exceed $25 million.
In practice, for transport operators in Australia, this means that Scope 3 emissions—those tied to the supply chain and outsourced logistics services—will soon be an essential part of carbon reporting. Consider a scenario where a freight company uses a third-party logistics provider (3PL) to manage its deliveries. Under the new regime, the company will be responsible for reporting the carbon emissions from that 3PL, even though they do not directly control the fleet or the delivery routes.
New Zealand is already ahead of the curve. Since January 2023, NZ has required large financial market participants, including NZX-listed companies and large insurers, to report under its Climate-Related Disclosures (CRD) regime. This reporting follows New Zealand Climate Standards (NZ CS), which align with the Task Force on Climate-related Financial Disclosures (TCFD) recommendations, making it an early adopter of global best practices.
For transport businesses in NZ, this reporting requirement applies not only to major companies but also to businesses with substantial environmental impacts. Take, for example, the logistics arm of a large retailer. Suppose the retailer’s operations include significant transport emissions, even if they are not directly responsible for the fleet. In that case, the company will need to account for and disclose the emissions related to its supply chain—potentially covering both upstream and downstream emissions.
While both countries have similar core objectives, such as improving climate risk management and driving down transport sector decarbonisation, there are some notable differences. These differences are essential for businesses to understand, particularly when managing the complexity of Scope 3 emissions tracking across jurisdictions.

Feature | New Zealand (NZ CS) | Australia (AASB S2/IFRS S2) |
Foundation | TCFD recommendations | IFRS S2 (aligned with ISSB) |
Scope of Entities | Limited to large market participants | Broad—covers all listed and unlisted entities down to $25M in assets (Group 3) |
Scenario Analysis | Requires three scenarios | Requires at least two (1.5°C and above 2°C) |
Assurance | Limited assurance initially, expanding over time | More rigorous, including reasonable assurance |
Liability | Similar to financial statements | Modified liability for Scope 3 until 2027 |
As we look ahead, it’s clear that emissions reduction initiatives will be at the heart of the transport industry's journey toward compliance. Businesses will need to focus on the full spectrum of emissions—from their direct activities to those from suppliers and customers. For Australian companies, understanding the emissions reduction targets in relation to the National Greenhouse and Energy Reporting (NGER) framework will be vital for staying on top of both transport emissions compliance and carbon disclosure regulations.
In New Zealand, businesses must also pay close attention to the NZ Emissions Trading Scheme, as it becomes increasingly important for industries like transport to participate in emissions trading to offset their carbon footprints actively.
As the push for decarbonisation intensifies, the transport sector—one of the largest sources of carbon emissions globally—finds itself under heightened scrutiny. In both New Zealand and Australia, transport businesses are not only required to comply with carbon reporting regulations but are also increasingly expected to take a proactive role in decarbonisation. This is not just about meeting mandatory requirements; it's about aligning with broader sustainability goals, securing long-term business viability, and contributing to national and global efforts to combat climate change.

When it comes to carbon reporting in the transport sector, understanding the categorisation of emissions is crucial. The Greenhouse Gas (GHG) Protocol divides emissions into three distinct scopes: Scope 1, Scope 2, and Scope 3. Each of these categories plays a significant role in how businesses track and report their emissions, particularly in relation to the complexities of Scope 3 emissions.
Real-life Example: A large freight company in Australia with a fleet of diesel-powered trucks will report emissions from the fuel consumed by those trucks as Scope 1 emissions. This includes fuel burned during long-haul deliveries, local runs, and even idling time at depots.
Real-life Example: In New Zealand, a logistics provider with a fleet of electric trucks must report the emissions associated with the electricity used to charge these vehicles. The company would report these emissions as Scope 2, especially if it purchases power from the grid.
Real-life Example: A transport company in Sydney may rely on a third-party 3PL provider for deliveries to retail stores. The emissions from the 3PL’s vehicle fleet will be classified as Scope 3, as they are indirect emissions that the transport company does not directly control. Additionally, the emissions from the packaging and shipping materials used to transport goods are also part of Scope 3.
When it comes to calculating Scope 3 emissions—which often represent 75% or more of a company’s total carbon footprint—accurate data collection and reporting are crucial. However, many transport businesses face significant hurdles due to the complexity of their supply chains and the need for data from multiple, often independent, sources.
The basic formula for calculating emissions across all three scopes is simple:
Activity Data × Emission Factor = GHG Emissions
Activity Data can include metrics such as fuel consumed (litres), electricity purchased (kWh), kilometres driven, or the amount of goods transported.
Emission Factors are used to convert this activity data into emissions, typically measured in CO₂ equivalents (CO₂e). These factors are based on scientific studies and are updated by the Intergovernmental Panel on Climate Change (IPCC).
For instance, calculating Scope 1 emissions for a fleet of trucks involves tracking the total litres of fuel consumed, then applying an emission factor specific to diesel fuel to estimate the total CO₂ emissions. Similarly, Scope 2 emissions for an electric vehicle fleet are calculated by tracking the amount of electricity used for charging, multiplied by the emission factor of the electricity grid in the region.
However, businesses often face the challenge of dealing with inconsistent or missing data for Scope 3 emissions—especially when relying on third-party suppliers. For example, tracking emissions from an overseas supplier’s operations is almost impossible without transparent data on their emissions practices. This lack of transparency and data consistency is one of the biggest barriers to effective Scope 3 emissions reporting.
For both New Zealand and Australian businesses, the introduction of mandatory Scope 3 emissions reporting requires a shift in mindset. Here are some of the most common challenges businesses face—and the strategies they can use to overcome them:
Strategy: Businesses should collaborate with suppliers and build strong, long-term relationships to improve data transparency. It may also be worth providing training or incentives to suppliers to help them align with sustainability goals and emissions reporting standards.
Strategy: Adopting carbon reporting software and automated data management systems can help streamline data collection and ensure consistency. These technologies can help centralise the data from various sources, making it easier to calculate, track, and report emissions accurately.
Strategy: Contractual arrangements can be amended to include sustainability clauses, requiring partners to provide emissions data. Additionally, forming collaborative initiatives with suppliers, such as sharing carbon-reduction infrastructure or co-investing in clean technologies, can drive down emissions across the supply chain.
The complexity of Scope 3 emissions tracking presents a significant hurdle for businesses in the transport and logistics sector. However, as reporting standards become more stringent and as the demand for transparency and accountability grows, the industry is adapting. In the next section, we’ll discuss strategies for leveraging technology and implementing decarbonisation initiatives to help transport businesses navigate these challenges.
As businesses in New Zealand and Australia adjust to the growing demands of carbon reporting, particularly in the transport sector, they face several key challenges. The complexity of emissions data collection, the integration of new technologies, and the financial investment required to meet stringent climate goals can feel overwhelming. However, with the right strategies in place, businesses can not only comply with new regulations but also gain a competitive advantage by adopting sustainable practices that reduce their environmental impact and drive operational efficiencies.
Real-life Example: A logistics company in Auckland might rely on a network of subcontracted freight carriers to handle the final leg of their deliveries. While the company can easily track emissions from its own fleet (Scope 1 emissions) and its electricity use (Scope 2 emissions), tracking emissions from its subcontractors' fleets (Scope 3) proves difficult. This lack of data not only complicates their compliance with New Zealand's mandatory carbon reporting regulations but also reduces their ability to accurately forecast their carbon footprint.
Strategy: To overcome this challenge, businesses can focus on building strong relationships with their suppliers and working collaboratively to improve data transparency. One potential solution is implementing data-sharing agreements with key suppliers, where they commit to providing emissions data as part of their contractual obligations. In addition, businesses can invest in carbon reporting software that integrates data across the supply chain, making it easier to track emissions even from external providers.
Real-life Example: In Sydney, a transport company may use a fleet management system to track the fuel consumption of its own vehicles, but the same company may rely on an external provider for data related to the transportation of goods through a third-party shipping company. The data from these systems may not integrate seamlessly, making it difficult to compile the emissions data needed for comprehensive carbon reporting.
Strategy: To streamline data aggregation, businesses should consider adopting integrated carbon reporting platforms. These platforms can consolidate emissions data from various systems—fleet management tools, energy usage records, supplier emissions reports—and automatically generate comprehensive emissions reports. AI-driven analytics can also help automate the process, reducing manual effort and improving data accuracy.
Real-life Example: A small freight forwarding business in Melbourne may have a single employee responsible for environmental sustainability efforts. This person is tasked with managing emissions reporting but lacks the technical expertise to track the emissions from the company’s third-party logistics providers, as well as the financial resources to implement an advanced reporting software system.
Strategy: For SMEs, leveraging cloud-based carbon reporting solutions can provide a cost-effective way to manage emissions reporting without the need for significant upfront investment. Many carbon reporting platforms offer scalable solutions that can be tailored to the specific needs of smaller businesses. Additionally, partnering with larger corporations or industry associations to share resources or data can help SMEs overcome resource constraints and improve their emissions reporting.
Real-life Example: A logistics company in New Zealand sets a target to reduce its carbon emissions by 20% over the next five years. However, the company does not base this target on scientific data or international climate standards. As a result, stakeholders—such as investors and customers—may question the effectiveness of the company’s carbon reduction efforts.
Strategy: To enhance the credibility of their carbon reduction efforts, businesses should align their targets with the Science-Based Targets Initiative (SBTi) or similar global frameworks. This ensures that the targets are both ambitious and achievable, and that they contribute meaningfully to the global goal of limiting warming to 1.5°C. In addition, businesses can work with third-party auditors to validate their emissions reduction strategies, further strengthening the credibility of their efforts.
Achieving carbon neutrality in the transport sector will require businesses to adopt a combination of technological solutions, operational changes, and collaborative efforts across their entire supply chain. By focusing on decarbonisation initiatives, businesses can go beyond mere compliance and gain a competitive advantage.
One of the most effective ways to simplify emissions reporting and improve compliance is by adopting carbon reporting software and automated data management systems. These tools can help businesses efficiently track emissions data across all scopes, minimise human error, and ensure consistency in reporting.
Automated Data Management: Investing in systems that automatically track, record, and report emissions data can save businesses significant time and reduce errors. These systems integrate data from various sources—fuel consumption records, electricity usage, and third-party logistics providers—and generate reports that align with regulatory requirements.
Analytical Tools: In addition to basic emissions tracking, AI-driven analytics and machine learning (ML) can optimise logistics routes, helping businesses reduce unnecessary fuel consumption and emissions. For instance, UPS’s ORION system has successfully saved the company millions of miles in driving and reduced fuel consumption by millions of gallons annually. Adopting similar technologies can lead to substantial cost savings and emissions reductions in the transport sector.
While technology plays a critical role, operational changes are equally important in achieving meaningful emissions reductions in the transport sector. Businesses should focus on several key decarbonisation levers:
Fleet Transition: Replacing traditional vehicles with electric vehicles (EVs) or alternative fuels such as hydrogen or biofuels can lead to immediate reductions in Scope 1 emissions. For example, Australia’s Electric Vehicle Council reports that the adoption of electric trucks can significantly reduce emissions, especially as the grid becomes greener.
Energy Sourcing: Businesses can also reduce Scope 2 emissions by transitioning their facilities to renewable energy sources. This includes adopting solar power, wind energy, or purchasing green electricity from suppliers who offer renewable energy options. New Zealand’s Emissions Trading Scheme (ETS) offers opportunities for businesses to offset their emissions by purchasing carbon credits from emission-reducing projects.
Logistics Optimisation: Optimising logistics operations can yield substantial emissions reductions. This includes improving route management, consolidating shipments, and shifting from carbon-intensive transport modes like air freight to more sustainable alternatives like rail or sea freight. Reducing empty truck runs, which account for a significant portion of emissions, is another key opportunity for operational improvement.
Since Scope 3 emissions typically account for the largest portion of a transport company’s carbon footprint, collaborating with suppliers and partners to reduce emissions is essential.
Supplier Engagement: Transport businesses should work closely with their suppliers to improve emissions reporting and help them implement decarbonisation measures. For example, a logistics provider can offer incentives to suppliers who meet certain emissions reduction targets, fostering a collaborative approach to sustainability.
Resource Mutualisation: Collaborating with other businesses to share infrastructure, such as charging stations for electric vehicles or warehouses that serve multiple companies, can help reduce costs and accelerate decarbonisation efforts.
Contractual Requirements: Updating contracts to require suppliers to disclose their emissions data can help businesses ensure they have the information they need to meet Scope 3 emissions reporting requirements. Businesses can also set clear expectations with suppliers regarding sustainability practices.
As we look toward the future of transport carbon reporting, it’s clear that businesses in New Zealand and Australia will face both challenges and opportunities. The push for decarbonisation will only intensify, with increasing pressure from both governments and the public to meet ambitious climate goals. However, the evolution of carbon reporting frameworks, coupled with advances in technology, presents a path toward more sustainable operations and better business outcomes.
In both countries, the transport sector has a critical role to play in helping nations meet their net-zero emissions targets. New Zealand, for instance, is aiming to reach net-zero emissions by 2050 under the Zero Carbon Act. Meanwhile, Australia is targeting a reduction of 43% in carbon emissions by 2030, as per its commitment under the Paris Agreement. These national targets necessitate a concerted effort from all sectors, particularly transport, which remains a significant contributor to both Scope 1 and Scope 3 emissions.
Transport businesses must act now to set science-based emissions reduction targets aligned with international climate goals. To achieve this, businesses should:
Set Short- and Long-Term Emissions Targets: Setting clear emissions reduction targets aligned with the Paris Agreement will guide businesses in the right direction. These targets should not only focus on direct emissions (Scope 1 and 2) but also extend to Scope 3 emissions across the supply chain. For example, a large freight company in Sydney might set a target to reduce its Scope 1 emissions by 25% by 2030 and its Scope 3 emissions by 15% by 2035.
Invest in Decarbonisation Technologies: As electric vehicle (EV) technology becomes more advanced and cost-effective, businesses should consider transitioning to EV fleets to reduce Scope 1 emissions. Additionally, alternative fuels such as hydrogen and biofuels will play a role in decarbonising sectors like long-haul trucking, which currently rely heavily on diesel. New Zealand’s Emissions Trading Scheme (ETS) provides an opportunity for businesses to offset emissions while transitioning to cleaner technologies.
Track and Report Progress: Regular reporting on emissions reduction progress is essential for maintaining accountability and transparency. Businesses should align their carbon reporting with internationally recognised frameworks like the Science-Based Targets Initiative (SBTi) and ensure their data is verified by third-party auditors. This builds credibility with stakeholders and demonstrates a commitment to meaningful climate action.
The regulatory landscape for carbon reporting will continue to evolve in both New Zealand and Australia. Governments are likely to introduce stricter emissions reduction requirements and enhance the scope of carbon reporting, particularly for Scope 3 emissions. These regulatory shifts will require businesses in the transport sector to be agile and prepared for changes.
Key future developments may include:
Expanded Scope 3 Reporting Requirements: While businesses are currently required to report on Scope 1 and 2 emissions, it’s expected that mandatory Scope 3 emissions reporting will become more stringent in the coming years. For example, both New Zealand and Australia may require companies to disclose the full carbon footprint of their supply chains, including indirect emissions from third-party logistics providers, packaging, and even customer usage of products.
Introduction of Carbon Pricing and Taxes: As carbon markets evolve, there may be more widespread implementation of carbon pricing mechanisms in both countries. This could include carbon taxes on high-emission sectors such as transport, or carbon credit systems where businesses must buy credits to offset their emissions. New Zealand’s ETS already provides a mechanism for trading carbon credits, and Australia may soon follow suit with its own carbon pricing strategies.
Mandatory Carbon Reduction Plans for High-Emission Sectors: Transport businesses, especially those in high-emission areas such as freight, logistics, and aviation, may be required to implement and disclose carbon reduction plans that outline specific actions to reduce emissions. This could include setting decarbonisation pathways for fleets, shifting to renewable energy for operations, or investing in cleaner fuels.
Looking to the future, technology will continue to play a pivotal role in simplifying carbon reporting, improving accuracy, and driving emissions reductions in the transport sector. Here’s a look at some key technological trends that are likely to shape the future of transport carbon reporting in both New Zealand and Australia:
Example: A logistics company could implement an AI-driven reporting platform that tracks fuel consumption across its fleet, energy use in its warehouses, and emissions from its third-party supply chain. This system could automatically generate reports for compliance with mandatory regulations and provide actionable insights for reducing emissions.
Example: A freight company could use blockchain to track the emissions of its third-party logistics partners across different regions. This would ensure that the data collected is verified, transparent, and auditable, reducing the risk of misreporting or fraudulent data.
Example: A fleet of delivery vans equipped with IoT sensors could monitor real-time fuel consumption and emissions data. This would allow the company to optimise routes, reduce fuel usage, and monitor fleet performance in real-time, helping them meet emissions reduction targets while improving operational efficiency.
The road ahead for transport businesses in New Zealand and Australia is clear: compliance with mandatory carbon reporting regulations is just the first step in a broader journey toward decarbonisation. While the transition to a low-carbon economy presents challenges—especially for companies managing Scope 3 emissions—it also offers significant opportunities for growth, innovation, and leadership in sustainability. By embracing decarbonisation technologies, collaborating across the supply chain, and setting science-based emissions targets, transport businesses can not only meet their regulatory obligations but also enhance their brand reputation, operational efficiency, and resilience in an increasingly carbon-constrained world.
Conclusion
Transport businesses in New Zealand and Australia must adapt to mandatory carbon reporting as part of national efforts to achieve net-zero emissions. Both countries have introduced frameworks—New Zealand's Climate Standards (NZ CS) and Australia's AASB S2—requiring businesses to report emissions across Scope 1, 2, and 3. Scope 1 and 2 cover direct and energy-related emissions, while Scope 3 includes emissions from the entire supply chain, which is a significant challenge for the transport sector.
Key challenges include data quality, especially from third-party logistics providers, and the complexity of Scope 3 emissions tracking. Businesses can address these challenges by adopting automated reporting software, engaging suppliers for better data transparency, and using technologies like blockchain and IoT sensors to improve emissions tracking.
The future will see tighter regulations, increased focus on science-based emissions reduction targets, and greater reliance on decarbonisation technologies. By aligning with global climate standards, investing in clean energy, and optimising logistics operations, transport companies can not only comply but also lead in sustainability.
