Commuters in downtown Barcelona have been able to ride the bus for free this week. There’s just one catch: this mini-bus has no one at the wheel.
The bus pulls away from the stop with its passengers on its own, brakes before changing lanes and eases down one of Barcelona’s most fashionable boulevards.
Renault is testing a new driverless mini-bus in Barcelona this week. The autonomous vehicle is running on a 2.2-km (1.3-mile) circular route with four stops in the center of the Spanish city. Adventurous commuters can jump on free of charge, The Associated Press reported.
The French carmaker has teamed up with WeRide, a company specializing in autonomous vehicles, to make the prototype. It unveiled the driverless bus at the French Open venue last year, but now it is testing it on the open road in Barcelona. It also has testing projects going in Valence, France, and at the Zurich airport.
Pau Cugat was one of the curious to step aboard for a short ride along Passeig de Gracia boulevard.
“We just passed by a regular, combustion-engine city bus, and I thought, ‘Look, there is a bus of the past, and right behind it you have the bus of the future,’” the 18-year-old student said.
Driverless taxis and buses are being tried out by companies in other cities, from San Francisco to Tokyo.
But Renault’s initiative comes as Europe generally lags behind the United States and China in driverless vehicle technology, where companies are fiercely competing to get ahead.
“The US is doing a lot of experimentation with autonomous vehicles, the same thing in China,” Patrick Vergelas, head of Renault's autonomous mobility projects, told The Associated Press. “Until now we don’t have a lot in fact in Europe. And this is why we want to show that this works and prepare Europe to this route in public transportation.”
The electric bus can run for 120 kilometers without a recharge and reach 40 kilometers per hour (25 mph). It is equipped with 10 cameras and eight lidars (sensor arrays) to help it navigate the streets filled with cars, motorbikes and pedestrians. The company says the bus is able to drive safely on a given course through a busy downtown like that of bustling Barcelona.
Carlos Santos, of Renault’s autonomous driving group, said that he has seen all types of reactions from riders.
“We’ve seen a lot of behaviors of people. Some of them were smiling, (while) other people just start crying, taking photographs or even try to open the doors," Santos said before he insisted that the bus ride was a safe one.
Barcelona's city officials said that they have had no reports of accidents caused by the experimental bus.

‘More and Faster’: UN Calls to Shrink Buildings’ Carbon Footprint

Countries must move rapidly to slash CO2 emissions from homes, offices, shops and other buildings -- a sector that accounts for a third of global greenhouse gas pollution, the United Nations said Monday.

Carbon dioxide emissions from the building sector rose around five percent in the last decade when they should have fallen 28 percent, according to a new report by the United Nations Environment Program (UNEP).

It said emissions had plateaued since 2023 as climate policies began to have an impact, particularly green building standards, the use of renewable energy and electrified heating and cooling.

But the building sector still consumes 32 percent of the world's energy and contributes 34 percent of CO2 emissions, the report found.

"The buildings where we work, shop and live account for a third of global emissions and a third of global waste," said Inger Andersen, Executive Director of UNEP.

"The good news is that government actions are working. But we must do more and do it faster."

She called on nations to include targets to "rapidly cut emissions from buildings and construction" in their climate plans.

The report said that while most of the countries that signed up to the 2015 Paris climate deal -- nearly 200 have signed -- mention the sector, so far only 19 countries have sufficiently detailed goals in their national carbon cutting plans.

The report said that as of 2023, important metrics like energy-related emissions and the adoption of renewable energy "remain well below required progress rates".

That means that countries, businesses and homeowners now need to dramatically pick up the pace to meet the 2030 emissions reduction targets.

- 'Critical challenge' -

Direct and indirect CO2 emissions will now need to fall more than 10 percent per year, more than double the originally envisaged pace.

The rollout of renewables is a similar story.

The share of renewables like solar and wind in final energy consumption rose by only 4.5 percentage points since 2015, well behind the goal of nearly 18 percentage points.

That now needs to accelerate by a factor of seven to meet this decade's goal of tripling renewable energy use worldwide, UNEP said.

The report urged countries to accelerate the roll-out of renewable technologies and increase the share of renewables in the final energy mix to 46 percent by 2030 -- a rise of around 18 percent.

It also called on policymakers to increase energy efficiency retrofits to include better design, insulation and the use of renewables and heat pumps.

More work also needs to be done to improve the sustainability of materials like steel and cement, whose manufacture accounts for nearly a fifth of all emissions from the building sector.

But the report did say that circular construction practices were increasing in some areas, with recycled materials accounting for 18 percent of construction inputs in Europe.

The authors urged all major greenhouse gas emitters to take action by introducing zero-carbon building energy codes by 2028, and called on other countries to create and tighten their regulations within the next 10 years.

The report highlighted positive national policies from China, France, Germany, Mexico and South Africa among others.

But it said financing remained a "critical challenge".

In 2023, it found that global investment in energy efficiency in buildings fell seven percent from a year earlier to $270 billion, driven by higher borrowing costs and the winding back of government support programs, notably in Europe.

Those investments now need to double -- to $522 billion -- by 2030, it said.
