what is the name of Grand Paris?

The good old formula metro, work, sleep always sums up the main concerns of the residents of Ile-de-France. Transport remains the black spot for improvement for the inhabitants of the Greater Paris metropolis.

During the round table “Is it still possible to travel cheaper and to pollute less? “, David Belliard, deputy (EELV) of the mayor of Paris in charge of transforming public space, transport, mobility, the highway code and the roads asked the central question: how do you get out of the car? citing the thousands of deaths from air pollution and the ravages of driving alone (one person, one car).

According to him, the solution involves mixed use (on foot, by bicycle, carpooling, car sharing). At RATP, Sophie Mazoué, Director of CSR, also highlighted the environmental benefits of public transport. Metro and RER users emit 50 times less CO2 than motorists.

“We are committed to halving our greenhouse gas emissions within ten years,” says Sophie Mazoué.

RATP will also convert its 4,800 buses to bio electric and CNG (natural gas for vehicles), an investment of € 4 billion.

Total Energies offers this type of green fuel but also relies on electricity with the construction of a gigafactory batteries with Stellantis and Mercedes.

“We are about to install charging stations, such as the 2,300 Vélib ‘stations, and provide them with carbon-free energy,” specifies Isabelle Patrier, director of France.

What to do against forced mobility?

With the arrival of winter and the energy crisis, it is important to cultivate sobriety.

“We have to ask ourselves about our energy consumption. The argument is to smoothly evolve the price increase “ points out Bertrand De Singly, customer director of the Île-de-France territory for GRDF. He offers to lower the speed, as on the device, and the mass, so go on a bike.

“What to do against forced mobility, which affects millions of residents in Ile-de-France? asks David Belliard: “We are 30 years behind on the rail network because we have invested little in daily public transport and we are paying the price. We need a Marshall Plan ”.

MaaS, this digital intermodality tool can be a solution: “We have implemented these devices in Annemasse, Brest and Angers and developed the Bonjour RATP application to promote multimodality” describes Sophie Mazoué.

Hydrogen for captive fleets like taxis and the river are two options to explore, says Isabelle Patrier (Total): “ we are on an energy mix and a decarbonisation of uses “. The Renewable Energy Acceleration Bill intended to catch up with France in wind and solar power should help.

The labor revolution is underway

Between teleworking and “major resignations”, the pandemic has changed the ways of working in urban areas.

“It has damaged the already tenuous link between fatigue, work and salary. The new generations no longer have the same relationship to work with, “says Emmanuelle Duez, founder of The Boson Project.

Greater Paris Metropolis is adapting to structural changes such as teleworking, which has gone from 4 to 30% of employees, carrying out actions on digital, third-party jobs and housing.

“The backbone of our actions is diversity and innovation,” explains Eric Cesari, vice president of the Métropole du Grand Paris.

“Sociologically, work allows us to exist in society” insists Montasser Jabrane, Founder and CEO of HandyCatch, who partnered with Havas to recruit a world first in the metaverse.

“This has raised questions of self-acceptance, particularly for people in priority neighborhoods and for people with disabilities. Now we want to become phygital ”.

Did the business districts survive?

As the metaverse is still in its infancy, office buildings are still a favorite place to work in Île-de-France. How to report employees, especially young people?

“You have to put five components together. A desirable office, which uses hotel codes. An office perceived as healthy (air, water, materials). A modular office because the flex office is practical. A service office (laundry on site) and finally a frugal office with the Ecowatt charter of commitments ”lists Éric Groven, head of the real estate department of Retail Banking in France at Société Générale.

Companies must sign a generational pact with the younger generations: “It forces them to ask themselves the question of their usefulness” analyzes Emmanuel Duez, for whom “Real estate must prove its sobriety”.

Did business districts like La Défense survive? “In fact, it is constantly evolving. But we need agility in the regulations “ says Éric Cesari, for whom the business district has a future if we relax “Our French colbertism”.

As for Éric Groven (Sogeprom), he underlines the desire of the defense administrators to make it the first post-carbon business district by 2030: “A seven-hectare urban park will open shortly and Paris La Défense will dedicate 360 ​​million euros to the renovation of public spaces. With the Grand Paris Express, La Défense will become very central ”.

The housing crisis, ecological and social emergency

The last sensitive topic for every inhabitant of Paris and its region: housing. The Greater Paris law enacted twelve years ago sets the number of new homes per year at 70,000. A bet that is far from being held according to Marc Villand, President and CEO of Interconstruction and President of the Federation of Ile-de-France real estate developers:

“We have seen a collapse in housing production since 2019. We have a supply and demand crisis. Prices are rising due to the increase in the cost of materials and land and banking problems ”.

Blame the mayors?

“No. The system is simply no longer adequate to the challenges of the region which weighs 2% of the national territory but 18% of the population, 31% of GDP, with 50,000 more inhabitants per year and 1 hour and a half of transport. on average “.

The promoter is asking for a global digital PLU in the Île-de-France region.

Delivery times too long

One week before the HLM congress in Lyon, social housing is at the center of attention: what solution to offer social owners with the 2% increase in the livret A tariff which will cost them two billion euros?

“There will be an impact, but this increase subsides over time, with loan terms ranging from 50 to 80 years. And the IRL (rental benchmark index) will increase by 3.5% “, replies Richard Curnier, regional director of Ile-de-France of the Banque des Territoires.

Too long delivery times for accommodation are also a problem.

“Construction is the only industry that has not undergone a revolution. The delays are getting longer and longer. We have to tackle new builds and renovations, ”says Sophie Meynet, general manager of the residential real estate division of GA Smart Building, an off-site construction specialist.

In this process, the 2D method consists in the prefabrication of concrete floors and walls (walls) in the factory. With the 3D method they are assembled in the factory with all the trades then taken to the construction site. Advantage: less transport and energy consumption and shorter delivery times.

An obese urban planning code

Olivier Tyl, President of the Versailles Interdepartmental Chamber of Notaries, recalls that building permits are issued every six years, which is the length of a mayor’s mandate, and that planning permits are long and complex. Result: The license window is quite short.

“It is always difficult to make the population outside the dense zone understand that it is necessary to build and that the model of the pavilion with a garden will no longer be sustainable everywhere” thinks Olivier Tyl. Without forgetting an Urban Planning Code “in a situation of obesity”.

Convincing mayors to build is not easy according to Stéphane Aubay, president of GreenCity Immobilier.

“Greater Paris Metropolis is fortunate to have sustained economic activity that attracts new populations. But local residents don’t really understand this change in their urban landscape, which needs to be made acceptable to them. “

Without forgetting to respect all the new environmental standards. “ZAN (zero net artificialization of soils by 2050) will be a brake. And the economic situation is getting tighter with prices that have become unsustainable “, admits Marc Villand, who announces an” extremely difficult “situation on the way.” The urgency is there: we can no longer do as before. construction “, concludes Sophie Meynet. An industrialization of the act of building that remains to be done.
