Twelve Consulting, a company specialized in consulting and digital solutions, labeled 2 stars Positive Company® since 2023, is actively committed to reducing its environmental impact by adopting a responsible approach to digital technology. This commitment is reflected in concrete actions in eco-design, responsible data hosting, optimization of IT equipment, and internal awareness of good digital practices.
Responsible hosting and eco-design of the website
A hosting rooted in France
Responsible hosting : the cloud services used by Twelve Consulting, including Salesforce and Microsoft, host their data in France, thus reducing the environmental impact related to data transport. The company favors cloud solutions committed to an approach of energy transition.
A 73% reduction in the website's footprint
Twelve Consulting improved the EcoIndex of its website from an average score between E and G to a score between B and D depending on the pages. Specifically, the carbon footprint of a visit decreased from 1.53 g of CO₂ in 2023 to 0.42 g in 2025.
The actions implemented:
- Removal of videos, particularly an auto-playing video on the homepage
- Reduction of animations
- Reduction of the weight of images and photos
- Optimization of contrasts for visually impaired and colorblind individuals, primarily using black and white

Optimization of internal processes
Dematerialization and reduction of storage

The company is also working to optimize the volume of data flows, deduplicate and archive/delete obsolete data to limit storage.
Raising awareness of digital eco-gestures
Employees are trained in managing the weight of email boxes, deleting obsolete data, and using good browsing practices (bookmarks, ad blockers).
The low code approach
Twelve Consulting relies on Salesforce and Microsoft platforms, thus limiting energy-consuming developments and favoring standardized solutions.
Vocabulary point:
Low code : software development approach that allows teams to develop digital solutions and create enterprise applications with minimal coding requirements.
Responsible policy on IT equipment
Optimization of provided equipment
- Each employee receives a reassigned laptop from a former employee, or a new one based on actual needs
- The company does not provide professional phones but covers the mobile plan
- Equipment renewal only after 4 years of seniority, except in the case of irreparable breakdown
Circular economy and donations via Emmaüs Connect
