Sustainable Development in Transportation

In an era of climate change, limited resources and global challenges that are redefining our existence, it is more crucial than ever to ensure that our solutions are optimized. Sustainable development is a priority for us, and a true corporate philosophy.


A culture of innovation at the service of sustainable development

Sustainable development is an important driver of innovation in engineering projects, and innovation is at the heart of CIMA+’s corporate culture.

Our teams are recognized for their ability to go beyond conventional solutions and push the limits of what is possible. This makes it possible to increase the environmental performance of projects, improve the quality of life and safety of the population while considering the economic and sustainable aspect of the proposed solutions. Their visionary spirit, boldness and ingenuity have been recognized and highlighted by numerous awards and commendations over the years, in all fields of engineering.

CIMA+ adopts a proactive approach that stimulates innovation from the very first stages of a project, with the objective of ensuring that it will have a positive impact on the environment and society. In addition, since any inspiration can become tomorrow’s great innovation, we encourage our employees to come up with new ideas. We have deployed a company-wide innovation strategy to facilitate the collection of suggestions and to centralize them. They are all analyzed by a committee and several are selected each year to be developed. Many of them are directly related to sustainable development.


Complete support for a sustainable and well thought-out project

Decisions made during the design phase can influence the environmental and social impacts of a project by up to 80%. Hasty decisions that are poorly adapted to socio-environmental issues can have repercussions throughout the life cycle of an infrastructure as well as on future generations.

At CIMA+, we advocate an engineering practice that assumes broader environmental, social and economic responsibility. To achieve this, it is essential to take a holistic view of a project’s life cycle and establish a strong synergy with all stakeholders from the start.

The Integrated Design Process (IDP) has been in place at our firm for many years. It is a proactive approach that stimulates innovation during the early stages of project design to ensure a positive impact on the environment and the community. IDP requires the participation of all stakeholders and the consideration of the life cycle of the structure, equipment and materials, extraction of raw materials, manufacturing, transportation and use of components. This approach is based on the principle of comparing the performance, costs, impacts and risks of different solutions, which is called value analysis.
We support the owner in thinking through and making critical decisions at the design stage (selection of materials, functionalities, technologies, manufacturing process, potential suppliers, project delivery method, construction approach [e.g., prefabrication, accelerated construction method or ABC], etc.).

To meet all its clients’ needs, including their various stakeholders and users, the CIMA+ Transportation team offers a range of complementary services that add to its expertise in sustainable development. Here is an overview:

By putting people at the heart of design, construction, operation and development decisions, we add significant value to real estate and transportation assets, generate cost savings and improve people’s experience, health and well-being.

In doing so, we help our clients to better understand the environmental impacts of their operations, the mitigation measures they can resort to and the principle of adaptation and resilience to climate change.



(1) Greenhouse gases (GHGs) consist mainly of carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and ozone (O3). They are gaseous components that absorb infrared radiation emitted by the Earth’s surface and contribute to the greenhouse effect.

(2) Embodied carbon is the sum of greenhouse gas emissions generated during the life cycle of a good or service (e.g. materials used in the construction of a structure or road such as concrete, steel, backfill materials, waterproofing membranes, etc.).

(3) ENVISION is an environmental and social certification dedicated to urban infrastructure assets such as roads, bridges, railways, airports, etc. (

(4) The ABC (Accelerated Bridge Construction) method allows the rapid construction and commissioning of bridges, sometimes in just a few days, with the aim of minimizing the impact on users and traffic.
