In 2020 Spain declared a national climate emergency. As mobility plays a big role in producing greenhouse gas emissions, Madrid and Barcelona are testing blockchain technology in transport services, while Valencia is studying innovative solar-powered e-ink displays in multimodal hubs

If computers transmitted data using photons instead of electrons, they would perform better and devour less power. European researchers are now studying a new light-emitting alloy of silicon and germanium to obtain photonic chips, which can revolutionise computing

Lowering consumption is not as simple as introducing a new gadget. Besides implementing innovative technologies, it is necessary to stimulate an end-user behavioural change. And cognitive sciences can support energy conservation attitudes

The Covid-19 emergency is trialling our technologies, infrastructure and laws. In this context the EU has released a common toolbox for contact tracing apps to support gradual lifting of confinement measures. From the frantic race against time to fight off the coronavirus, we will inherit scientific and technological knowledge that could make our cities smarter and better equipped to face such global crisis in the future

The coronavirus emergency won’t affect the timeline of the EU’s Green Deal. This is despite some fossil-fuel-reliant countries asking the Commission to put its flagship policy on hold, even if they stand to benefit most from the Deal's Just Transition Fund

Global warming has brought about a more responsible attitude towards water consumption. A cutting edge airborne technology can save water lost through leaks while reducing energy use and carbon emissions

Researchers are trying to investigate whether the human body has specific odours a person feels happy or sad. The aim is to develop a dispenser that can spray substances able to help patients suffering from phobias and depression

Energy policy is obviously gender neutral. But should it be so?

New technologies have offered a low cost and easy way to travel, but most tourist cities are failing to keep pace with managing the increased visitor flows. However, the same ICT sector is now being called on to deliver smart solutions to deal with overtourism and avoid the congestion of city centres
