Waltr, the ally of local authorities for sustainable environmental management
Cities are at the heart of today's climate and health challenges:
80%
European citizens live in areas where pollution exceeds WHO recommendations¹
Urban pollution costs
166 billion
euros per year to Europe²
90%
climate plans lack detailed data to guide their strategy³
Cities with real-time data have local policies
3x
more effective⁴
Objectify your local ecological transition policies with our environmental data
This is where Waltr comes in, offering local authorities and regions expertise based on the fusion of satellite data and field measurements.Waltr produces dynamic maps that allow users to instantly visualize areas of different types of pollution and identify the exact sources of emissions, at the granular level of neighborhoods, such as traffic-related air and noise pollution, heat islands, road congestion, and emissions from industrial and logistics areas.Waltr allows you to obtain all this data and bring it together in a single tool to enhance your current initiatives, such as climate plans (PCAET), noise prevention plans (PPBE), or land use strategies.
Supporting your ecological transition
But beyond technology, Waltr is committed to supporting local authorities in this transition by training their teams, raising awareness among elected officials, and facilitating communication with citizens. At Waltr, we firmly believe that the ecological transition is a collective effort in which every stakeholder, whether a decision-maker or a resident, must play their part.
Reducing resistance to change
By combining transparency, active listening, and stakeholder involvement from the outset, resistance diminishes and is replaced by gradual acceptance.
Enhanced commitment and motivation
The involvement of the various stakeholders, teamwork, and quick wins stimulate everyone's commitment.
Facilitating deployment and reducing the risk of failure
The involvement and commitment of the teams, as well as a clear action plan, streamline the implementation of the project and ensure its successful rollout.
Aligning practices with tools
Increased strategic and operational performance.
01
Targeted pre-diagnosis
This phase clarifies your needs and expectations, sets out objectives, and reveals the initial areas for action to be explored in greater depth. We analyze the social and organizational context alongside interviews tailored to your situation.
02
Comprehensive in-depth diagnosis
We conduct individual and group interviews to understand behaviors, perceptions, and social mechanisms. Our expertise enables us to identify obstacles and levers to facilitate change. Following this analysis, we deliver tailored recommendations and action plans.
