It is difficult to get reliable data on how long we hold onto the 24 billion edge devices attached to the global ICT infrastructure. Diverse device types and cultural practices complicate the issue. So do changing purchase and lease plans. Here is our latest calculation on the average in-service life of a mobile device and a look at how unused devices are piling up in UK homes.

The availability of tablets suitable for Green ICT purchasing has declined percipitously over the past year. We could identify only three manufacturers offer one model each. The sluggish global market for tablets may account for manufacturers' lack of interest in certifying new models.

A full update of this survey is planned for later in the year. In the meantime, we are noting an achievement by USA carrier Sprint.

The January 2019 Consumer Electronic Show (CES) gave a Sustainability and Eco-design award to the LG 55E9 55-inch E9 OLED 4K TV. CES noted the model was "...made of eco-friendly and recyclable materials including natural glass."

The LG 55E9 is not listed in the EPEAT Televisions Registry, but the listed LG models are all registered as 'Silver' or 'Bronze'.

In fact, the entire EPEAT Televisions Registry is still disappointing. There are no Gold units for the United States and only 158 Silver, mostly from Samsung.

Scandinavia's Nordic Ecolabel (Svanen) registry lists 88 models, up a little from last year. Samsung makes 78 models; the others are from Philips.

No televisions were recognized in the United States Environmental Protection Agency's Champion Award category of the 2018 Sustainable Materials Management (SMM) Electronics Challenge.

The US ENERGY STAR program looks only at energy efficiency and not other sustainability factors. The program uses a metric called Total Energy Consumption (TEC).

There were only four models rated at 50 TEC or less this year, less than half as many as a year ago. Apple TV, with two of the four models, is by far and away the most efficient, helped by its very low stand-by power consumption.

The European Union has a program for STB energy efficiency and we've listed the manufacturers that signed its Code of Conduct. There are also three European STB models that received the German Ecolabel.

Research suggests that design decisions are the dominant factor in the sustainability of e-gear.

We have counted ~25 billion devices attached to our global ICT infrastructure. Many of these are Internet-of-Things (IoT) devices. IoT has all the Green ICT issues of any tech segment. How many IoT devices will we see deployed in the next coming years? It is instructive to see how forecasts have been becoming more conservative.

Our latest update looks at the potential value of the e-waste recycling market and at the challenges nanoscale ICT poses to realizing that potential.

How much gear is attached our global ICT infrastructure? Our 2017 inventory counts almost over 24 billion 'edge' items, The latest update to these counts is consumer Internet of Things (IoT).
