Example:
- SimaPro version: 1.01. SimaPro Professional 9.3 (Jan 2022).

---------------------------------------------
A paragraph summarising the method

e.g. The EF method is the impact assessment method of Environmental Footprint initiative. The implementation is based on EF method 3.0 published for use during the EF transition phase. It includes the normalization and weighting factors published in November 2019.

> **This is a really important note about a method, e.g. a limitation, assumption that users must read!!
> Note the arrow on each line (block quote). Double asterix adds emphasis.**

Implementation by PRé Sustainability
----------------------------------------------
## Major Adaptations by PRé Sustainability:

- Additional substances have been included as they are extensively used by the background databases and their synonyms are part of the original EF method:
Resource use, energy carriers - flows expressed in mass units (not only in net calorific value as in EF); characterization factor corresponds to the lower heating values of given fuel;
Resource use, mineral and metals - additional flows for already characterized mineral and metals;
Water scarcity - for flows representing geographies not covered in the original EF method the global factor was applied;
Climate change:
- carbon dioxide (emission to air) is included with factor 1 (like carbon dioxide, fossil in the original method);
- carbon dioxide, to soil or biomass stock (emission to soil) is included with factor -1 (this flow is necessary for the correct modeling of land use in ecoinvent);
- carbon dioxide, in air (raw material) is included with factor 0 (like carbon dioxide, fossil and carbon dioxide, biogenic in the original method).

Detailed Information

(More detailed information on the modelling and sources for each impact category can be found below)

## Impact Category 1
Description of impact category 1. What does it mean? What is the time horizon? What are the units? Does it have any adaptations?

## EF-Ozone depletion
Impact indicator: Ozone Depletion Potential (ODP) calculating the destructive effects on the stratospheric ozone layer over a time horizon of 100 years.

Version History
------------------
This is a summary of the changes. Changes are made to the version history each time the method is updated.

2. No line-break between points in the bullet point list (otherwise not rendered by markdown renderers)

## e.g. Pré Sustainability - Update for SimaPro 9.2 (June 2021, 1.01)
Added characterization factors to the water use category, for new water flows in the ecoinvent 3.7.1 database to ensure compatibility.
