Greenpeace Aotearoa hangs a massive banner on the offices of the Fertiliser Association of New Zealand in Wellington. The banner draws attention to the link between synthetic nitrogen fertiliser and the climate crisis, and contains the names of 30,000 people that have signed a petition calling on the NZ Government to phase out the use of synthetic nitrogen fertiliser.

Synthetic nitrogen fertiliser emits greenhouse gas nitrous oxide. In New Zealand, the nitrous oxide released via application of synthetic nitrogen fertiliser to land contributes more equivalent emissions than NZ's entire domestic aviation industry.
