[[File:New Zealand aviation emissions of greenhouse gases.svg|thumb|New Zealand emissions of greenhouse gases from aviation]]In a 2008 effort to develop an [[aviation biofuel]], Air New Zealand and Boeing researched the [[jatropha]] plant to see if it was a viable green alternative to conventional fuel.<ref>{{Cite news| title=Air NZ sees biofuel salvation in jatropha| website=Carbonpositive.net| date=6 June 2008| url=http://www.carbonpositive.net/viewarticle.aspx?articleID=1114| access-date=31 July 2010|archive-url=https://web.archive.org/web/20081211115803/http://www.carbonpositive.net/viewarticle.aspx?articleID=1114|archive-date=11 December 2008}}</ref> A two-hour test flight, using a 50–50 mixture of the new biofuel with [[Jet fuel|Jet A-1]] feeding a [[Rolls-Royce RB211]] engine of one of the airline's 747-400s, was completed on 30 December 2008. The engine was then removed to be scrutinised and studied to identify any differences between the jatropha blend and regular Jet A1. No effects to performances were found. The use of jatropha was identified as a possible future fuel but large tracts of low quality land needed to grow the plant would have to be found without impeding other agricultural uses.<ref>{{cite news|url=http://news.bbc.co.uk/2/hi/science/nature/7805499.stm|title=Vegetable oil tested on NZ flight |date=31 December 2008|work=[[BBC News]] |access-date=31 December 2008| archive-url= https://web.archive.org/web/20081231091937/http://news.bbc.co.uk/2/hi/science/nature/7805499.stm| archive-date= 31 December 2008 | url-status= live}}</ref>
In 2022, Air New Zealand adopted a 2030 target to reduce its emissions by almost 29%.<ref>{{cite web |url =  https://www.bbc.com/news/articles/czrjzvep41ro |title = Air NZ becomes first big carrier to drop climate goal |work=  BBC |date= 30 July 2024 |access-date= 19 February 2024 |first = João |last = da Silva}}</ref>
In July 2024, Air NZ had announced the withdrawal of its 2030 climate target and that it would also withdraw from the [[Science Based Targets initiative]] (SBTi). The Spinoff website reported that this raises serious credibility questions for Air New Zealand.<ref>{{cite web
