Tiakina Te Taiao is our first Waka Kotahi sustainability monitoring report.
The report gives us a baseline of the impact that the land transport system has on our environment right now. We will use it to track progress towards a low carbon, safe and healthy land transport system. We already hold a lot of information about our impacts, but we have some gaps to fill and we have highlighted how we will improve reporting which will evolve in coming years.
This inaugural report uses 2018 (calendar year) as the baseline, unless specified.
- Greenhouse Gas (CO₂) emissions from road transport increased to 11,700 kilotonnes in 2018 and 55% of the emissions were from urban areas.
- More people using public transport contributes to the environmental and safety outcomes we seek. 26% of people in urban areas live near a frequent public transport service.
- Electric vehicles are an important part of a sustainable future and reducing range anxiety encourages uptake. 96% of the state highway network is now within 75 kilometres of an electric vehicle public charging station
- Air and noise emissions impact adversely on peoples’ health. NO₂ concentrations are generally below World Health Organisation (WHO) guidelines, but around 38,000 people are exposed to high levels of traffic noise in Aotearoa New Zealand.
- Active travel improves public health and reduces emissions. 12% to 26% of trips in urban areas are by walking and cycling.
- Using resources more efficiently preserves them for future generations and reduces impacts on the environment. 2.2% of materials used in state highways maintenance contracts in 2019 were recycled.
- Waka Kotahi corporate emissions increased to 5,004 tonnes of CO₂ in 2019, 87% of which were from flights.
