Four levels, and why they are not the same thing
A registered action is not a verified environmental result. Here is the difference, without figures this platform has not measured.
Level 1 means a person says an action was done. That is valuable as participation, and that is all it is.
Level 2 means supporting material was submitted. Level 3 means an authorized reviewer has seen that the material supports the action. Level 4 means an outcome was assessed with an approved method, including uncertainty.
This installation accepts level 1. No approved measurement methods are published yet, so no verified results are shown.
Source: This text is the platform's own accounting principle, not a scientific paper.
Accessibility: Text without audio or video. The paragraphs are short. There is no time limit.
Where it applies: Applies in any climate. No local study is attached to the text.
Practice
An answer shows whether you read the statement. It does not raise the evidence level and it earns no recognition.
