# 1. Introduction The Nature Climate Standard (NCS) operates a registry in which emissions avoidance, reduction and carbon removals (collectively mitigation outcomes) are registered as Carbon Credits. These mitigation outcomes are generated from forest projects that meet the requirements of the NCS. The NCS, which is described in detail in this document, lists the requirements that ensure that the climate impact of these projects is measurable. In summary, the carbon credits must be additional, long-lasting and calculated according to the latest scientific evidence. NCS is built on top of ISO 14064-2:2019 and adds further requirements to this norm. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
