Public health risks associated with transport emissions in New Zealand

New report by Emission Impossible Ltd prepared for the Ministry of Health

Transportation in New Zealand – which encompasses road, rail, maritime transport and aviation – emits a wide range of air pollutants, many of which present a public health risk. The adverse effects of transport emissions are significant in New Zealand. The social costs of transport-related harmful air pollution are currently estimated at $1.21 billion per annum (in $2019) as a result of New Zealanders dying prematurely, being admitted to hospital or suffering days lost due to illness or poor health. Transport sources also emit direct or indirect climate pollutants. Transport-related greenhouse gas emissions add an additional $1.68 billion in social costs per annum (in $2019).

This report is the first step in addressing the research question: “What are the risks to public health associated with road, sea, rail and air travel including vessel emissions, dusty roads and vehicle emissions in New Zealand?” It draws on a stocktake and gap analysis of the current state of knowledge across various transportation sectors as at 30 June 2021.
