Together, we can design the resilient, sustainable cities of tomorrow

At a time of climate change, biodiversity loss and increasing scarcity of available natural resources, we can support your local authority by increasing sustainability and enhancing the well-being of residents with more efficient, resilient, safe and inclusive projects.

Our engineers apply their technical and scientific expertise to devise, create and upgrade the infrastructure needed for a healthy, safe and sustainable environment.

Our aim?

To support your environmental transition, from the definition of development strategies to the installation of infrastructure.

Our role is to:

Design

infrastructure that is safe and accessible to all

Adjust

existing infrastructure to make your city resilient, focusing on local usage and resources

Improve

the environmental footprint of your project and of infrastructure usage

Lead

large, complex projects – including those that involve a variety of participants – while remaining on time and on budget

By your side at all stages of your project

Taking a systematic, holistic approach to projects, factoring in all socio-economic and financial parameters to support your ecological and digital transitions: frugal use of resources, nature-based solutions, circular economy, smart objects, etc.
Meeting your residents’ expectations by factoring environmental and health risks into your projects: flooding, heat islands, noise pollution, air quality, water resources, etc.
Co-ordinating the whole urban service value chain, including access to water, treatment of effluents, management of waste, telecoms and transport infrastructure, public and green spaces, and energy production.

Concrete solutions tailored to the challenges of climate change and the low-carbon transition

To address climate and ecological transition issues, we help clients develop their vision and define their strategy regarding climate adaptation and carbon reduction.

Taking a collaborative approach, we create practical, custom solutions by putting together a committed, multidisciplinary team, along with suitable tools. Advising you by taking a holistic approach based on three key aspects:

Strategic consulting

Diverse skills in the energy, climate and environmental fields, along with solid knowledge of regulations, to help create a low-carbon economy.

A holistic approach that aims to address current challenges related to climate change and to guide you towards more sustainable and resilient practices:

Low-carbon strategy
Devising your strategy for reducing GHG emissions and developing a plan to reduce carbon emissions from your activities
Climate risks and adaptation
Understanding the exposures and vulnerabilities of regions and organisations in terms of climate risks, and putting in place an adaptation strategy
Resource strategy
Understanding the environmental impact of your activities and devising a plan to reduce impact and preserve resources

Sustainable urban planning consulting

Designing projects that consider the specific features of regions and cities, while ensuring optimal integration with urban and transport infrastructure and preserving nature.

We work alongside you to design cities that are resilient and pleasant to live in, by combining an integrated sustainability strategy with specific implementation requirements:

Cities and mobility
Combining expertise in mobility, urban planning and the climate, to design mobility projects tailored to the specific features of each city and region.
Urban resilience
Developing resilient urban projects, using the right tools and anticipating technical and operational engineering work.
Circular economy
Giving fresh impetus to urban renewal: reducing the amount of resources consumed in urban development and recovering resources resulting from that development

Digital expertise

Comprehensive support from drafting the statement of requirements to designing custom digital solutions.

We offer a full range of digital services for environmental professionals, including consultancy, project owner assistance and the design and development of custom digital solutions.
