Our impact
2025 Impact Report
Toitū's Impact Report highlights the measurable change our clients have achieved with the support of our expert team between July 2024 and June 2025. From reducing emissions to improving sustainability performance and driving positive environmental outcomes, it demonstrates the tangible contribution of our work across New Zealand and beyond.
Here’s a snapshot of our collective impact this year:
- 918 clients supported, with 779 on our Climate Impact and Enviromark programmes
- 1,005 certifications issued across Climate Impact, Enviromark, and non-programme
- 60.2 million tonnes CO₂e certified or verified during FY25
- 108,000 tonnes of high-integrity carbon credits were retired by our clients

Our emissions reporting
We are a signatory of the Climate Leaders Coalition and we seek to be equivalent to Toitū Net Carbon Zero. We measure our carbon emissions annually and have the results independently verified, alongside our climate performance targets and achievements. We purchase and cancel a selection of high-integrity carbon credits to compensate for operational emissions we have yet to reduce.
The reporting data shown here is for the July 2023 to June 2024 timeframe. Our data for the July 2024 to June 2025 period is booked for external verification early 2026, and this page will be updated soon after.
As the owner and operator of the Toitū Net Carbon Zero certification programme, we do not claim to be certified, however, we meet all the same requirements as our certified clients.
- We continue to include emissions from purchased goods and services and focus on our value chain activities.
- Air travel emissions continue to increase post-COVID but remain lower than our starting point in 2016.
- We are on track to meet our 2030 targets.
We are currently well on track to achieve our 2030 targets, with a 62% reduction in scope 1 and 2 emissions for this period compared to base year, and a 63% reduction for business travel compared to base year. Our emissions profile has increased (again) in FY24 compared to the previous period as our operations continue to scale up.
Toitū’s total emissions for FY23/24 were 271.82 tCO2e. You can read our Climate Performance Summary for a good overview, or you can deep dive into our Carbon Inventory Management Report here.
Emissions Comparison Table, FY 2022-2024
| Activity | 2016/2017 emissions (tCO2e) | 2022/2023 emissions (tCO2e) | 2023/2024 emissions (tCO2e) | Notes |
|---|---|---|---|---|
| Purchased goods & services (including freight) | 0.19 | 159.87 | 181.26 | The increase is due to higher spend while we use spend-based methods |
| Air travel | 79.71 | 53.30 | 62.30 | Travel remains lower than base year, but has increased year-on-year since COVID |
| Vehicle travel, including employee commuting (car, bus, taxi, rail, ferry) | 5.00 | 35.10 | 15.49 | -- |
| Working from home | -- | 6.70 | 5.54 | -- |
| Accommodation | 0.62 | 3.78 | 5.33 | Reflects the overall rise in travel as our business growse numbers. |
| Electricity | 2.13 | 1.15 | 1.76 | Increased due to changing office premises. |
| Waste | 0.06 | 0.06 | 0.13 | -- |
| Total | 87.71 | 259.95 | 271.81 | Without the addition of purchased goods and services, total emissions were 90.55 tonnes. |
Our significant sources
We saw a 21 tonne increase in purchased goods and services emissions due to higher spending. Due to resource constraints, we have not yet shifted toward more specific data and quantification methods to improve our calculation accuracy.
Another source which increased is business travel, increasing by nearly 7 tonnes. We anticipate that the travel emissions will fluctuate in the next few periods as the business grows, but remain focused on our 2030 target.
Our purchased electricity emissions also increased this year, breaking a year-on-year reduction trend. This was due to moving offices in Wellington where the building has a lower occupancy.
Emissions reduction targets
We are committed to managing and reducing our emissions in line with our Toitū Net Carbon Zero programme requirements. We have validated near-term targets under the Science Based Targets initiative. Our current near-term targets are:
- Absolute reduction of Scope 1 & 2 emissions by 74% by 2030
- Absolute reduction of Scope 3 business travel (including employee commuting) by 57% by 2030.
Due to increasing the scope of our emissions measurement, we plan to update our near-term Scope 3 targets and have these revalidated by the Science Based Targets initiative. As part of the process, we will reassess our plans and targets to see how the business transformation will affect our emissions ‘curve’ – the point at which emissions will peak and start declining.
For the first time, we have set long-term targets for a 90% emissions reduction. We believe we can do this for Scope 1 and 2 by 2040, and have set a target of 2050 for Scope 3. Our next step will be to work through the formal validation of these targets and related action plans.

Climate-related risks & opportunities
Overview
What are climate-related risks and opportunities?
Climate change affects all of us, and the impacts will only intensify as global heating continues. Climate-related risks are those that arise from the impacts of a warming climate, as well as those related to the human responses to climate change and our transition responses. Risk assessments aim to understand the nature and level of climate change related risks, as well as opportunities. The assessment process will guide your organisation in how to reduce and respond to these risks, but if done thoughtfully can also highlight opportunities to build resilient operations, new revenue streams, and robust strategies for decades to come.
Understanding climate risk and opportunities enables an organisation to prepare mitigation strategies and identify business opportunities. The process to assess potential scenarios, determine the risks and opportunities ahead, and plan how to manage them will ensure an organisation is much more resilient in years to come. The assessments support risk prioritisation, which can then drive targeted action and investment in adaptation.
Understanding your climate risks and opportunities demonstrates company foresight and resilience to stakeholders and builds your organisation’s brand as a climate leader.
Climate scenarios
Climate change scenarios are a way of describing possible future changes to climate variables and hazards. There are a range of future climate scenarios based on the level of global heating that occurs. The scenarios help guide thinking on the severity and likelihood of impacts on operations, facilities, value chains and communities.
Toitū’s scenario-based approach for this process uses guidance developed by the Intergovernmental Panel on Climate Change (IPCC); we focused on three key scenarios: orderly, disorderly and hot-house world.
Orderly: This is our best-case scenario based on a very stringent pathway and likely limits climate heating to around 1.5C. In this scenario, carbon dioxide emissions decline from 2020, reaching zero by 2100, with methane reducing in half; this scenario also requires negative emissions through removals, such as forest-based sequestration.
Disorderly: This is considered an intermediate scenario, with projected temperature rise of 2 or 2.5C. While it is the most probable scenario, it does depend on very sharp and stringent decarbonisation enacted in the 2030s. In this scenario, carbon dioxide emissions decline from 2045, reaching half (compared to 2050) by 2100, with methane reducing by about 25% compared to projected 2040 levels; this scenario also requires negative emissions through removals, such as forest-based sequestration.
Hot House World: This is taken as our worst-case scenario, resulting in climate heating of 3 or 4C. This scenario would see minimal change to current behaviour and practices, and thus emissions continue to rise throughout the 21st century.

Our B Corp score
Being a B Corp organisation supports our ambition for environmental regeneration and economic sustainability. We are proud to have been a B Corp since 2019, most recently recertified in 2022 . The work we have put in since the initial certification has really paid off – our score increased from 82 to 106.8 in our 2022 audit. The score increased across all five impact areas: governance, workers, community, environment and customers.
Toitū is currently reviewing the enhanced B Corp framework, which was released in mid-2025. We expect to recertify under the new B Corp standard, and this will likely extend our recertification timeline.
Governance
- We updated our company constitution to show that we: consider all stakeholders when making decisions, commit to running our business for good, and consider impact on the environment and society over profit.
Workers
- We conducted a pay equity analysis to identify gender and ethnicity pay gaps.
- We increased our diversity, equity and inclusion training offerings to our people.
Community
- We’ve continued to support employee volunteer hours.
Environment
- We continued to progress against our science-based targets for our greenhouse gas emissions.
- Our primary impact business model, recognised by B Corp, is helping clients to improve their impact on the environment and society through our work.
- A second impact business model, relating to the environmental education we provide, has been recognised.
Clients
- We recertified our impact business model, recognising the results members achieve in our programmes.
