Climate Neutrality

“Climate neutrality” is defined by the entire set of policies that an institution uses when it estimates its known GHG emissions, takes measures to reduce them, and purchases carbon offsets to “neutralize” those emissions that remain

  • UNEMG (Environmental Management Group) EMG/AM.07/05/Rev.2

The ICAO Carbon Calculator is used UN-wide in support of the Climate Neutral UN Initiative
