Use of advanced biofuels for engine tests
In order to reduce its greenhouse gas emissions and support the emerging sustainable aviation fuel sector, Safran decided to incorporate advanced biofuels into the kerosene used on aircraft and
Green Days: eco-habit initiative to save energy
Safran Electronics & Defenseimplemented on its Montluçon site a Green Days initiative that was broken down into several actions that aimed to save energy and improve energy efficiency, thereby reducing the site's carbon footprint.
Main project's drivers for reducing the greenhouse gas (GHG) emissions
Energy and resource efficiency
Energy Decarbonisation
Energy efficiency improvements
Improving efficiency in non-energy resources
Emission removal
Financing low-carbon issuers or disinvestment from carbon assets
Reduction of other greenhouse gases emission
Project objectives
Aim of the Green Days initiative: to save energy and reduce the GHG emissions of the Montluçon site thanks to investments made on the site and the roll-out of best practice (eco habits)
This initiative responds to the following sub-goals:
- To address the obsolescence, age or regulatory noncompliance of certain infrastructure-related equipment (refrigeration units, boilers, lighting) through energy-saving actions. To integrate safety issues;
- To involve all employees in the initiative;
- To work on the infrastructure as well as the processes
Detailed project description
The Green Days initiative on the Montluçon site was broken down into various actions which were taken:
- Implementation of an energy-saving initiative based on the ISO 50001 method (roll-out of an “energy” policy and energy-performance indicators);
- Implementation of a dedicated organizational structure with an energy manager and coordinators responsible for leading the initiative in the various workshops;
- Use of continuous-improvement tools like the Green Belt workshops (Lean Transformation): optimization of electricity use on weekends, energy efficiency of the clean rooms, efficiency of the means of production, etc.
- Energy-saving actions on infrastructure: insulation, relamping, improvement of settings and management of the installations;
- Actions on production: switching equipment off at the end of a shift, optimization of the ancillary equipment of the means of production (cooler, pump, etc.), definition of the selection criteria of the new means of production engineering;
- Grouping of heat, cold, compressed air and vacuum production processes in an adapted building: the Energy Building. These means of production were old, disproportionate and noncompliant in a few areas. This five-year project (2016 to 2020) led to a 40% reduction in natural gas use while also securing industrial activity through the introduction of the best methods available (heat recovery, speed variation, etc.) and a search for financial optimization (search for a rapid ROI).
Emission scope(s)
on which the project has a significant impact
Scope 1
Direct emissions generated by the company's activity.
Scope 2
Indirect emissions associated with the company's electricity and heat consumption.
Scope 3
Emissions induced (upstream or downstream) by the company's activities, products and/or services in its value chain.
Emission Removal
Carbon sinks creation, (BECCS, CCU/S, …)
Avoided Emissions
Emissions avoided by the activities, products and/or services in charge of the project, or by the financing of emission reduction projects.

Illustrations of the project
This Green Days initiative offers several benefits to the project owner:
- Manage the site’s energy bill, limit the impact of energy-cost increases,
- Ensure continuity of service and comfort while improving energy efficiency and safety
- Integrate maintenance and optimization constraints of equipment into projects
The methods of all of these projects can be reproduced: size to exact needs, implement the best methods available, use the energy sources available. These projects also desensitize a site to market prices.
Several factors play a role in the initiative’s success:
- Working closely with operational staff to reduce energy use of the processes and create complementary improvement loops on the infrastructure
- Implementation of energy coordinators in the various sectors to manage the action plans
- Identifying sources of funding: Ademe’s request for proposals, various grants (energy-saving certificates (CEE), ADEME)
As all of these forms of technology are very mature, these projects are carried out as part of works launched through calls for tenders. The projects are carried out with local small and medium enterprises and/or large national groups.
Awareness-raising actions are performed in-house with the support of Ademe through local “Energy info” appointments.
