Global action.
Local impact.
Introducing a new global initiative to address nitrous oxide (N2O) emissions — the N2O Hub.
N2O is a potent and long-lived greenhouse gas. It traps around 273 times more heat than carbon dioxide and remains in the atmosphere for up to 110 years. N2O emissions are rising each year.
Our Goals
Nearly three-quarters of human-caused N2O emissions come from nitrogen-based fertilizers and manure on farms. Most of the remaining emissions come from industrial sources.
The coalition’s main aim is to unite countries, NGOs, philanthropies, and industry leaders around a shared commitment to mitigate N2O emissions. Together, we can forge a path for change that matters both globally and locally.
We will collaborate with countries to include N2O targets in Nationally Determined Contributions (NDCs) under the Paris Climate Agreement. We will also launch awareness campaigns highlighting the significance of N2O in climate change and ozone depletion.
What We Do
Unlocking action on N2O: the overlooked greenhouse gas threatening our future
Reducing emissions of nitrous oxide (N2O ) is important to achieve internationally agreed climate goals, prevent further damage to and allow for a full recovery of the ozone layer, and improve human health and biodiversity outcomes.
We’re working to spur action, both in global energy goals and in resources for local communities. Join us to drive change.
Quick Facts
Rising Emissions: N2O emissions are increasing faster than projected worst-case scenarios.
Mitigation Strategies: Existing technologies can reduce industrial N2O emissions by up to 99%.
International Actions: Recent global efforts include UNEA’s Sustainable Nitrogen Management Resolution and the Global Methane Pledge as a model for international cooperation.

Near-term opportunities for international action to mitigate emissions of nitrous oxide
Why it Matters
The hidden impact of N2O is fueling climate threats – join us to drive change
We are developing a new effort to raise global ambition and to catalyze new action addressing this oft-forgotten greenhouse gas. We need your help.
Integrating N2O mitigation into climate policies, with international coordination and funding to drive change, will make a difference. Please consider becoming a partner in this urgent effort.
