Our sustainability
commitments and achievements

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 summary of the impact we've supported this year:

• A client base of 918 New Zealand and international organisations
• 779 organisations committed to the Climate Impact or Enviromark programmes
• 1,005 certifications issued
• 60.2 million tonnes CO₂e certified or verified
• 108,000 tonnes of high-integrity carbon credits retired

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 2024 to June 2025 timeframe and compares it to our July 2022 to June 2023 baseline year.

Our latest reporting benefits from greater methodological accuracy. We updated our baseline year this period to meet programme guidance and better reflect current business conditions, following material changes to our operations, emissions boundary, and calculation approach.

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.

Executive summary

• We recorded a 24% reduction in Scope 1, 2 and 3 emissions compared to base year.
• We continue to focus on reductions across our value chain activities.
• We developed a supplier‑specific emissions factor for clients to calculate emissions from Toitū’s services.
• We are on track to meet our near-term 2030 targets.
• We have developed long-term 2050 targets.

In FY24/25, Toitū recorded total gross emissions of 214.46 tCO₂e, representing a 24% reduction in scope 1, 2 and 3 emissions for this period compared to base year. The decrease was primarily driven by lower emissions from purchased goods and services, along with reductions from decreased business travel.

Emissions Comparison Table, FY 2022-2025

Our significant sources

Purchased Goods and Services remained our most significant source of emissions in FY24/25, reflecting the scale of our value chain impacts. While improvements were made to emissions factor accuracy and estimation methods this year, progress toward more detailed data and active supplier engagement was limited by resource constraints.

Business travel was the second largest emissions source. Travel emissions are expected to fluctuate as the organisation evolves, while we remain focused on managing travel demand and maintaining progress toward our longer‑term emissions reduction objectives.

Emissions from staff commuting and home working were the third largest source this year, informed by improved data collection during the reporting period. Other operational sources, including electricity, paper, and waste, remained relatively small contributors to our overall emissions profile.

Emissions reduction targets

We are committed to managing and reducing our emissions in line with our Toitū Net Carbon Zero programme requirements. Following a rebaseline of our emissions inventory this year, we have developed new near and long term, science-aligned targets. They are currently undergoing internal review and may be submitted for SBTi re‑validation in 2026.

Our new near-term targets are:

• Absolute reduction of Scope 1 & 2 emissions by 42% by 2030
• Absolute reduction of Scope 3 emissions by 42% by 2030.

Our new long-term targets are:

• Reduce absolute Scope 1 and 2 emissions by 90% by 2050
• Reduce absolute Scope 3 emissions by 90% by 2050

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.

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.
