This workshop aims at gathering researchers and developers from the fields of Internet of Things, Pervasive, Ubiquitous Computing and Green ICT to discuss the possibilities of new applications and services which decrease the carbon footprint of IoT, and which exploit IoT to reduce the carbon footprint of our society.

The evolution of ICT has led to the diffusion of wireless personal devices, such as smart mobile phones, personal computers and wearable devices, designed to operate over the Internet. This, together with the exponential growth of the number of interconnected devices is leading towards the commonly called Internet of Things (IoT).

Presently, a large share of the total energy consumption of the Internet takes place at the edge. This share is increasing with the progressive deployment of the IoT, which is reshaping the edge of the network, and which in the near future is bound to generate the large majority of traffic on the Internet.

Though usually small and not power hungry, the sheer number of the devices composing the IoT will make them the highest contributors to total energy consumption in the ICT sector.

For meeting the challenge of a greener Internet, therefore, a greener IoT is fundamental. This involves elaboration of new approaches at the device level (energy efficient, energy proportional devices) as well as at the system level (algorithms for energy efficient network services as well as application layers services provisioning).

On the other side, the pervasiveness of sensing and computing capabilities in IoT is enabling a wealth of new applications for energy efficient management in almost all domains of human activity, from transportations to lighting, from waste management to the smart grid.
