Transurban Group Strategy Overview

CLIMATE CHANGE PROGRAM Current and future climate-related risk management priorities Our Climate Change Framework priority areas Towards Net Zero Transurban Scope 1 and 2 emissions: 50% reduction by 2030 • Transition to zero-emission fleet . ⚫ Contractor targets for fuel efficiency, and ensure contractor vehicles are zero-emissions vehicles by 2030 Ongoing lighting upgrades and delivery of ventilation optimisation program . Install more onsite renewables • Investigate PPA for remaining NSW assets, and for Victoria and North American markets Scope 3 emissions: 55% reduction in emissions intensity for major projects, 22% reduction in emissions intensity for purchased goods and services ⚫ Supplier commitments to renewable energy, Science Based Targets initiative or carbon neutrality Low carbon and circular materials strategy • Enhanced major project specifications Climate resilience training and capacity building Financial physical climate risk and adaptation assessment ⚫ Measure and quantify the identified long-term impacts of both the climate- related risks and adaptation measures Business-wide Climate Risk Adaptation Guideline • Develop standardised approach across our markets • Develop compulsory training module Scope 3 does not include customer emissions; however additional opportunities are being investigated to understand and address customer emissions Scope 1 and 2 emissions: net zero emissions Transition to 100% renewables, eliminate fuel from vehicle operations > wherever possible, implement supply chain requirements Scope 3 emissions: net zero emissions Electricity grid transition to renewables, reduce travel-related emissions across the supply chain, influencing our investment partners to undertake similar programs, carbon offset where residual emissions cannot be avoided Continued integration into business operations Development of climate-related metrics across our asset lifecycle models and traffic models to continuously improve business resilience and future climate- related projections Resilient infrastructure and operations Asset Specific Climate Risk and Adaptation Management Plans • Management plans will include an aligned risk and adaptation approach and include a risk assessment, adaptation measures required, broad financial implications and triggers and thresholds • Ongoing risk and adaptation assessment reviews and workshops FY22 Time horizons not to scale TRANSURBAN OVERVIEW | AS AT 30 JUNE 2021 FY23 FY24 ⚫ Continued reporting, governance, and use of scenario analysis FY25 FY30* FY50* 14
