One New Zealand is one of Aotearoa New Zealand’s largest telecommunications companies.

Through TILT, The Lever Room has supported the One NZ team with organisational emissions measurement and reporting, setting science-based targets through the Science Based Targets initiative (SBTi), and developing a practical plan to achieve those targets.

The work has included a comprehensive assessment of Scope 3 emissions gaps, evaluation of the most appropriate Scope 3 target-setting approach, and preparation and submission of targets for validation. We have also developed a clear, evidence-based GHG Reduction Implementation Plan, setting out the actions required to achieve One NZ’s selected SBTi targets.

Our work with One NZ has extended into product-level carbon modelling, including an avoided emissions assessment for its refurbished phones pilot. The assessment compared refurbished devices with equivalent new devices to quantify the carbon benefit of choosing refurbished over new. This helped One NZ strengthen the customer proposition, support credible communications, and connect circular economy initiatives with Scope 3 emissions reduction.

Together, this work demonstrates how TILT supports climate action beyond reporting. We help organisations build the evidence needed for emissions reduction, commercial decision-making and credible market communication — from organisational greenhouse gas measurement and science-based targets through to product-level analysis supporting lower-carbon products and services.
