- Human activity produces greenhouse gas emissions, both directly and indirectly. Measuring these emissions is one of the crucial first steps to implementing a responsible sustainable development policy. With this in mind, Citelum has adopted French environmental agency ADEME’s carbon footprint assessment method.
- ADEME developed the Bilan Carbone® carbon footprint assessment so that businesses and local governments can measure the amount of greenhouse gases generated by their activities. Emissions measurements, stated in tons of CO2, incorporate factors like direct energy consumption, employee commuting and business travel, goods and services purchased, and end-of-life waste disposal. Citelum worked directly with Jean-Marc Jancovici, creator of the Bilan Carbone® carbon footprint assessment, and carbon strategy consultancy Carbone 4 to implement the method.
The Bilan Carbone® method measures reductions in greenhouse gas emissions starting from a baseline. The measurements can then be used to set even more ambitious greenhouse gas reduction targets. Based on ADEME recommendations, Citelum developed a carbon conversion tool and, more recently, a method for tracking the environmental impact of light fixtures—a factor that is just as important as price and performance in the Citelum systems and services lineup.
The goal is to choose equipment manufactured using raw materials and processes that generate the lowest possible amount of CO2, in order to ensure that our systems and services remain focused on sustainable performance.

Sustainable development charter
- For today’s businesses, a sustainable development charter is crucial to implementing environmental policies. Citelum’s service-level agreements set forth concrete steps toward sustainability and regulatory compliance.
- Growing numbers of cities worldwide have turned to Citelum for street lighting services that improve energy efficiency while addressing two major issues:
- City growth and the resulting need to expand networks, add equipment, and build infrastructure
- The need to reduce energy consumption
Citelum is a leader in innovative responses to the challenges of sustainable development. Our systems and services are backed by service-level agreements that include penalties for non-performance. Our comprehensive approach has helped city planners gain a deeper understanding of how important lighting infrastructure is to any city planning project.
In 2004 we put our commitments in writing. Our Sustainable Development Charter sets forth the many ways in which our business contributes to the common good.
Energy performance contract
- An energy performance contract is designed to help local governments reach ambitious energy-efficiency targets and reduce their greenhouse gas emissions. These contracts are governed by EU regulations.
- Energy performance contracts enable local governments to work with private-sector service providers to improve the energy efficiency of a given public service. Modernization, new equipment purchases, and extensions to existing infrastructure are financed by the energy savings achieved during normal operation of the public service. To be eligible, projects must be both complex and urgent.
Citelum has leveraged the energy performance contract to offer its services to local governments. However, because the projects are complex, more comprehensive public-private partnerships are often required.
Urban lighting eco-management
- Today, controlling spending on street lighting, traffic lights, and artistic lighting is a top priority for local governments. Energy efficiency is, of course, crucial. It is also a concrete step towards meeting sustainable development objectives.
- However, energy efficiency requires investments that local governments often postpone for budgetary reasons. Citelum helps cities implement comprehensive urban lighting eco-management systems to help boost energy efficiency.
When cities choose our comprehensive management services, they can use the savings generated to finance a large proportion of investments to modernize, expand, or upgrade their existing equipment. Citelum’s response addresses issues like:
- Upgrading outdated equipment
- Minimizing downtime
- Streamlining operations
- Fine-tuning the power consumed by each light fixture
- Managing energy more efficiently
- Computer-assisted maintenance refers to the use of software to manage the maintenance of urban equipment.
- Computer-assisted maintenance software provides a comprehensive view of all equipment, helps coordinate day-to-day tasks, and helps streamline maintenance work. Citelum, in conjunction with its Citegestion subsidiary, has developed Packweb®, today’s leading street lighting and traffic light management system.
- Comprehensive management of all street lighting services gives city planners and managers new possibilities in terms of innovation and energy efficiency.
- Comprehensive management includes engineering, lighting design, new installations and upgrades, and operations and maintenance. These services can cover all of Citelum’s business lines (street lighting, traffic lights, artistic lighting, and other urban electrical equipment). Comprehensive management services can also be combined with energy performance contracts and public-private partnerships, in which case the private-sector service provider is bound by a service-level agreement with specific performance targets.
- LED (light-emitting diode) lamps can help improve energy efficiency and reduce lighting maintenance costs.
- When it comes to urban electrical equipment, LED technology is today Citelum’s number-one choice for optimizing operations and working toward sustainable development goals. LED lamps to have their limitations, however, and are not always suitable for street lighting, either for technical reasons or price constraints (LED equipment is more expensive than traditional equipment).
Citelum has developed a process for assessing the equipment available on the market to ensure that the best possible equipment is used on each project.
- Light pollution has multiple facets, from over-lighting to overly-bright lighting and lights that produce a halo effect.
- The use of artificial lighting is on the rise. The environmental impact of lighting is often ignored, resulting in light pollution and wasted energy. Light pollution earned a top slot on the French government’s environmental agenda, and new laws were passed to control light pollution.
France passed a law on August 3, 2009 (French law 2009-967) giving the government the power to regulate the installation and operation of any equipment deemed to be a source of light pollution. Even tighter regulations for certain areas—around observatories and nature reserves, for instance—could be just over the horizon. The law also provides for sanctions including prohibiting the use of polluting equipment.
Citelum’s Luxicom® technology helps cities reduce light pollution. Citelum also recommends replacing traditional light fixtures like fluorescent tubes and globe lamps with more appropriate fixtures like those with reflectors.
- Packweb® is a fully-customizable multidomain software solution. It is constantly updated to reflect the latest technological advances in urban electrical equipment and feedback from operations and maintenance staff.
- Packweb® computer-assisted maintenance software was developed by Citelum subsidiary Citegestion. Leveraging a database that is updated in real time via mobile terminals every time operations or maintenance work is carried out, the software manages equipment, projects, interfaces, energy consumption, and reports.
- Today’s cities need lighting that reflects their unique features and helps city planners meet their development goals.
- Citelum and its Architecture Lumière Conseil subsidiary first developed the illuminated pathway concept in the 1990s as part of the lighting masterplans and city lighting masterplans created for customers. The goal was to revitalize public areas and provide a more beautiful, exciting environment for residents. Our illuminated pathways lead residents and visitors through the city’s historic monuments and heritage buildings, highlighting each feature and point of interest with artistic lighting. Illuminated pathways can also be used to ensure visual and spatial continuity between different areas of a city.
Remote lighting management
- Citelum has developed remote lighting management technology for smarter street lighting management. Cities can now provide just the right amount of light for any given location or time of day, generating substantial energy savings.
- Remote lighting management is based on an innovative application that turns lights on and off and adjusts the power to each light fixture as needed. The software closely monitors all equipment and can pinpoint malfunctions on specific light fixtures. The solution is eligible for the French government’s energy performance certificate program.
