Jyros, the tool that allows you to measure your company's environmental impact

JYROS is a world first: an environmental footprint calculator created by and for companies in the video game industry. JYROS enables you to calculate the entire carbon footprint of your company (studio, publisher, etc.), from the impact of your premises to that of your games, including your IT equipment. On top of this, JYROS also lets you estimate your company’s impact on other environmental criteria (impact on water and mining resources in particular), making it the most comprehensive calculator available to date for the video game industry.

A tool developed by video game companies for the video game industry

In order to create the most accurate and scientifically robust tool possible, its creation was subcontracted to I Care, for its expertise in GHG emissions assessments and life cycle analyses. Having already collaborated with ADEME (the French Agency for Ecological Transition) on a study about the impact of digital technologies in culture, I Care was the ideal candidate to tackle this project. To support I Care and ensure that JYROS would be as comprehensive, representative and user-friendly as possible, companies within the industry were enlisted to support this project.. 27 companies from all over France, representing the diversity of the industry, responded to the invitation to test JYROS and participate to its improvement.

They're talking about us.

JYROS: how does it work?

JYROS enables you to easily enter all the data related to your business (energy consumption, business travel, hardware purchases, etc.) and the games you develop (file size, length, platforms, etc.) and then calculates the environmental impact of the various expenditure and production items. The results are presented in charts, with varying degrees of detail depending on your choices, allowing you to target your actions to reduce your impact.

An initiative of the National Consortium for video games for the environment

The National Consortium of video games for the environment is a collaboration between several French professional bodies: regional clusters and associations as well as the Syndicat National du Jeu Vidéo (SNJV) and the Syndicat des Editeurs de Logiciels de Loisirs (SELL). The main goal of this project is to kickstart the environmental transition of the French video game industry. JYROS is the first stage in this project.

This operation is supported by the French government as part of the “Supporting green alternatives in culture” initiative in the cultural and creative industries (CCI) sector of France 2030, operated by Caisse des Dépôts.

Here are comments from some of the video game companies involved in the creation of JYROS.

Gameleon Studio

Aurélie Marion - Co-Founder

As a small company, it was obvious for Gameleon to be one of the pilot studios to join in the development of an innovative tool dedicated to our field. Today, environmental issues are crucial for all companies, whether they are small or very large. As a major industry, the video game industry shows here a prime example of its determination to take action for the future. Being able to measure our carbon impact allows us to evolve according to tangible and measurable data. This is all the more essential not only in terms of sustainable development, but also in terms of attractiveness, in order to attract and retain increasingly demanding employees with high expectations for meaningful projects and a solid CSR policy.

Old Skull Games

Guillaume Magnies - CFO

The collective commitment to sustainability was the driving force behind the consortium and convinced us of the project's dynamic. Jyros embodies a vision of a more environmentally friendly video games industry.

Thanks to Jyros, we now have the ability to accurately and comprehensively assess the carbon footprint of our studios and each game we develop.
One of the most rewarding aspects of Jyros is its free accessibility.
We are convinced that to drive significant change, we need to make this tool accessible to all studios, regardless of their size or resources.
We are proud to contribute to the development of a Cultural Industry where consideration of environmental impact is essential to forging a more responsible industry that respects the planet.

Asobo Studio

Gregory Carreau - COO

Asobo Studio is grateful and proud to have had the opportunity to contribute to the development of Jyros alongside Game Only, the Consortium and the other pilot studios.

It's an essential initiative with a collective approach that gives the entire video games industry a tailor-made tool to take very concrete action towards greater eco-responsibility.
