# Data Dimensions & Metrics

## How Dimensions and Metrics Work

Tracenable datasets follow a dimensional model.

* **Dimensions** are the attributes you can use to analyze or slice the data. Each dataset is defined by one or more dimensions.
* **Metrics** are the most granular layer: each one represents a unique combination of dimension values that defines a specific data point.

This dimensional model provides a transparent and predictable way to structure data. It removes ambiguity in naming, ensures consistency across datasets, and makes it easier to understand how each metric is constructed.

## Dimensions in EU Taxonomy Data

The EU Taxonomy data is organized along three core dimensions. These dimensions define how EU Taxonomy data is categorized and reported, and every metric in the dataset is derived from their combinations.

* *<mark style="color:$success;">**Level**</mark>**&#x20;-*** Identifies whether the disclosure applies to the company’s total business or is broken down by specific economic activities.
  * `Total`
  * `Activities`
* *<mark style="color:$success;">**KPI**</mark>**&#x20;-*** Represents the key performance indicators (KPIs) required by the EU Taxonomy, used to quantify how a company’s business activities align with sustainability criteria.
  * `Turnover`
  * `CAPEX`
  * `OPEX`
* *<mark style="color:$success;">**Eligibility Category**</mark>* or *<mark style="color:$success;">**Screening Criteria**</mark>**&#x20;-*** Defines the sustainability classification of economic activities under the EU Taxonomy.
  * `Aligned`
  * `Eligible`
  * `Denominator`

## Metrics in the EU Taxonomy Dataset <a href="#metrics-in-the-waste-dataset" id="metrics-in-the-waste-dataset"></a>

EU Taxonomy metrics are derived by combining the three dimensions: **Level**, **KPI**, and **Eligibility Category / Screening Criteria**. Each metric represents a standardized data point that shows how a company’s activities align with the regulation.
