New release: SimaPro 9.1.1 is here!

We are glad to introduce SimaPro 9.1.1! This new version includes several small software improvements, updates of impact assessment methods and the latest version of the Agri-footprint database. Last but not least, the current release reflects the new SimaPro brand identity.

By Michiel Oele, SimaPro Product Specialist at PRé Sustainability

After the previous major software update, the current version contains a series of bug fixes and small improvements. For users, the focus has been on databases – ensuring quality, consistency and accuracy of the data and impact assessment methods.

Updated database: Agri-footprint 4.1
New database: Agri-footprint 5

Updated method: AWARE
Superseded method: GHG protocol
New method: IPCC 2013 GWP 100a (incl. CO2 uptake)

Below you can see the highlights of this release. For a full overview of changes, please refer to the ‘What’s new in SimaPro 9.1.1‘ manual.

Changes to data libraries

Agri-footprint 4.1

Agri-footprint 4.1 is an improved version of 4.0 in which some errors are corrected. Moreover, the economic database includes 5 new datasets from Evonik; these are amino acids for feed.

This version is only available as an update for users who already had version 4.0, and will not be provided with new SimaPro installations.

Agri-footprint 5

Agri-footprint 5 is now available in three different libraries within SimaPro, based on mass, energy or economic allocation. It includes linked unit process inventories of crop cultivation, crop processing, animal production systems and processing of animal products for multi-impact life cycle assessments. Agri-footprint also contains inventory data on transport, fertilizer production and auxiliary materials.

Some of the new features of this database are:

  • Focus on more markets: besides the Dutch feed market, now there is a stronger focus for feed materials in European and American markets.
  • Update on activity data for crop cultivation: Next to an update of the source data, new models have been developed to quantify inputs and emissions in more detail.
  • Expansion of scope for crops: more countries are included in the new version.

Replacement files are available to help users update their projects from Agri-footprint 4.1 to the new Agri-footprint 5. More information on these replacement files and how to use them is available in the relevant update manuals or on the Agri-footprint 5 website.

Changes to impact assessment methods


The method is updated to the most recent version 1.2c. This influences the vast majority of characterization factors.

GHG protocol

This method is no longer supported and has been moved to the Superseded category. It has been replaced with a new method “IPCC 2013 (with carbon uptake)” as this better reflects the needs of the impact assessment method to be used with the GHG protocol.

IPCC 2013 GWP 100a (incl. CO2 uptake)

We included this special version of the IPCC method which includes CO2 uptake, as accounting for CO2 uptake is relevant for the following standards:

  • Greenhouse Gas Protocol
  • ISO 14067
  • PAS 2050

Please be aware that CO2 uptake must be counterbalanced by end-of-life emissions to avoid strange (negative) results.

How to update to SimaPro 9.1.1?

Everyone with a valid service contract from September 30, 2020 onward can update to SimaPro 9.1.1. As usual, you will need to update the software, then import the update database and append substances. For all recommendations and step-by-step instructions, please refer to the update manuals available at the SimaPro Help Center. These manuals also include the relevant download links.

What’s next?

New database: World Food LCA Database

World Food LCA Database (WFLDB) is a comprehensive international life cycle inventory database and a global initiative led by Quantis in partnership with leaders in the agri-food sector. The database was launched in 2012 in response to the growing need for reliable, transparent and coherent environmental data and a consistent methodology for assessing the impacts of agri-food products. WFLDB is now available exclusively for SimaPro users as an additional download (free of charge)!
