Les réseaux de froid urbains, méconnus, sont de solides alternatives à la climatisation classique. À Paris, la Seine permet de rafraîchir 800 bâtiments. D'autres villes ont sauté le pas.
Un réseau de froid est une sorte de labyrinthe glacé. D’abord, une centrale frigorifique refroidit une boucle d’eau indépendante. Cette dernière refroidit ensuite — sans se mélanger — de longues canalisations qui se fraient un passage sous terre afin d’atteindre chaque bâtiment. Une fois arrivée, l’eau refroidit le petit réseau indépendant du bâtiment, qui refroidit l’air qui est projeté dans le bâtiment, comme une climatisation classique.

Entre 2012 et 2022, Paris a vu ses niveaux de pollution baisser de manière significative. Selon le dernier rapport d’Airparif, ces progrès tiennent autant à la modernisation des véhicules qu’à la réduction du trafic et aux politiques menées sur d’autres sources de pollution.

La transformation écologique est-elle possible sans réinventer l’action publique ?
Dominique Méda, Selma Mahfouz, Marylise Léon et une vingtaine d’acteurs et actrices de terrain prennent la parole pour nommer les blocages, et ouvrir des pistes concrètes d’action.
Il est temps de reprendre le pouvoir d’agir, dans les institutions comme sur les territoires.

With the number of passenger vehicles rising across Europe, cities are grappling with air pollution, traffic accidents, and the loss of public space. In Spain, the city of Pontevedra has managed to overcome these challenges, surpassing national air quality standards and creating safer streets. The key, according to the Galician municipality’s mayor, is an urban model that prioritises residents over cars – without imposing an outright ban on private vehicles.

En quatre ans, la Métropole francilienne a déployé 137 km d’infrastructures cyclables et vise à doubler ses réalisations. Et si les élections municipales étaient l’occasion de changer la hiérarchisation des modes de transport urbains ? Pourquoi ne pas imaginer que les prochaines équipes municipales fassent passer les modes de déplacement doux en tête devant les transports collectifs et la voiture ? Nous n’en sommes probablement pas encore là.

The study found that black cars increased heat by almost 4°C on hot summer days.
On a scorching summer day, a parked car can feel like a furnace. New research from Lisbon shows that the effect isn’t just uncomfortable, it could be warming entire neighbourhoods.
And the colour of your car could be making it worse.
In a new study published in City and Environment Interactions, scientists found that dark-coloured vehicles radiate far more heat than light ones, raising nearby air temperatures by several degrees.

Europe’s food system is failing the very people it’s meant to serve, as decades of trade-driven, industrial agriculture have left local farms disappearing, biodiversity declining, and citizens paying hidden social and environmental costs. Far from delivering true food security, this fragile model depends on distant supply chains and cheap imports often produced under standards Europe itself wouldn’t accept.

A housing association in the Borders is converting garages into homes in a bid to ease the current crisis.
Scottish Borders Housing Association (SBHA) has created seven luxury bungalows in Jedburgh from rows of derelict lock-ups, with a further six nearing completion in neighbouring Hawick.
Their first tenant, Jeanette Elliot, had been housebound for almost five years, due to access stairs, before moving into her new home this month.

The energy crisis, driven by fossil fuel price shocks, has pushed nine million households in England into fuel poverty – spending over ten per cent of their income on energy bills. Current government support schemes aren’t helping. The Warm Home Discount provides only £150 annually, which falls far short of the £407 average fuel poverty gap, and only lifted one per cent of households out of fuel poverty in 2024.

The Croatian Hydrocarbon Agency’s exploratory activities at a preliminary exploration site in Velika Gorica have confirmed significant geothermal potential. The output from this single geothermal well could meet nearly 60% of the thermal energy needs of the city’s district heating system, the agency said.

La période estivale nous ramène souvent à nos lieux d’origine – une plage, une ferme, un banc, un champ, une route, un village… Pour moi c’est ce village corse de Marignana, berceau de ma famille maternelle, accroché à la montagne au-dessus du Golfe de Porto, classé au Patrimoine de l’Humanité par l’UNESCO – un village d’une centaine d’habitants à l’année, sans commerce autre qu’ambulant depuis plusieurs décennies, et qui a la chance d’avoir encore un café (pas ouvert en continu) et un café-auberge qui déploie des efforts admirables pour accueillir les randonneurs du GR20, proposer une restauration de terroir et déployer une animation culturelle toute l’année (avec un cinéma qui sert aussi de salle de spectacle ou de concert). L’été m’y ramène chaque année et ce n’est pas un hasard – car les lieux que nous avons traversés nous habitent bien plus qu’on ne le pense, et ne nous quittent jamais vraiment quand nous les quittons.

Over the last decade and a half, Copenhagen has adapted its infrastructure to a wetter future, overhauling critical components of its urban design and infrastructure to transform itself into a “sponge city,” writes Paul Hockenos in a piece in Yale Environment 360.

As Spain takes a breath after yet another brutal summer heatwave, with temperatures above 40C in many parts of the country, the residents of the sherry-making town of Jerez de la Frontera have come up with a novel way to keep the streets cool.
Green canopies of grapevines festoon the town, reducing street-level temperatures by as much as 8C. “We’re planting vines in the old city because we hope that in two or three years we’ll be able to brag that this has put an end to stifling temperatures,” said Jesús Rodríguez, president of Los Emparrados, a group of residents who aim to beautify and green the city’s streets.
Qui dans la société doit payer les coûts d'une aggravation du changement climatique et de ses évènements extrêmes ? Quels mécanismes de solidarité à l'égard des plus exposés ou des plus vulnérables ? Comment financer et déclencher les actions de prévention pertinentes ? Quels rôles de l'Etat et du secteur assurantiel ? Ce rapport du Haut-commissariat à la Stratégie et au Plan est le fruit d’un travail original ayant mobilisé un groupe de travail pluridisciplinaire pendant près de deux ans.

The project is a direct response to the ever-pressing global need to tackle the climate crisis through the lens of culture: it is born from the conviction that culture, especially in the form of cinema, has the power to engage with one of the most critical challenges of our time: environmental sustainability.

IN A NUTSHELL:
Despite claims that eating locally is the most important factor in making sustainable food choices, production is what generates the majority of food related emissions, not transport.

Since June 2025, three billboards in the borough of St Werburghs have been half demolished. One is now nothing more than a rusty frame, whilst the other still sport ads slowly peeling and fading. We never liked these billboards but this is a whole other level.

In a quiet corner of Vienna’s well-to-do 18th district, Jana is explaining how her assembly of wooden decking and planters is bringing a bit of greenery to the area. “There’s not a single tree on this whole street – it’s just parking spaces on both sides.”
This is a grätzloase, or neighbourhood oasis – a miniature park tucked into the side of the road. With the blessing of the city hall, more than 100 of them have sprung up across Vienna. The scheme has been growing since 2015, and its proponents say it’s struck a rare balance for urban projects: cheap, community-driven and appreciated by local people.
