We've tracked the growing environmental impact of cryptocurrencies like Bitcoin since 2013. We've focused on cryptocurrency mining's GHG footprint, which has grown to equal that of large cities. Now, we learn that cryptocurrency transactions have a large footprint, as well.

IEEE Spectrum reported in October 2019 that researchers at the Federal Polytechnic School of Lausanne in Switzerland estimate that each Bitcoin transaction generates an estimated 300 kilograms. (Bitcoin transactions frequently exceed 300K/day.) "...Bitcoin broadcasts messages to its entire network to get everyone to confirm each transaction. In order for blockchains to reach consensus on the validity of all transactions, users must execute complex, energy-intensive computing 'proof of work' tasks." The researchers developed this estimate while working on a new algorithm to confirm transactions that could reduce the footprint to only a few grams per transaction.

The "C" in Green ICT is Communications. Green America reports that, "The four largest companies – AT&T, Verizon, Sprint and T-Mobile – collectively use more than 30 million MWh of electric power each year. AT&T and Verizon, the two leading US companies in the industry, have a combined electricity usage that could power 2.6 million homes for a year...A large portion of this energy (90%) powers wireless access networks, towers and other infrastructure allowing cell phone users to access data and connect nationwide." Here's how telecoms are doing from a Green ICT perspective.

Researchers and businesses are advancing innovative ideas with potential for mainstream Green ICT. These range from products and services available today to futuristic concepts for tomorrow. The latest is Dell's gold recycling program, including the creation of jewelry from motherboard gold.

The number of Green ICT conferences and workshops to decline, now to only half as many as in 2013. They have almost disappeared from North America and Asia/Pacific, with Europe hosting over half. The good news is that we listed one in Africa and one in the Middle East.

Energy efficiency is becoming more important to supercomputers, as ever more powerful machines consume ever more energy. Japan and the United States lead energy-efficient supercomputing. (A liquid immersion ExaScaler module of the top machine - Shoubu system B - is pictured to the left.)

The most recent update on global e-waste from a consortium of international organizations gives us new data about the problem's scope and grow. Per-capita e-waste growth is slowing, the overall amount is growing with the world's population.

The issues around the use of metals in e-devices is more complicated than just the matter of conflict minerals. A recent report suggests devices might be more sustainable if they used more plastics and less metals.

Our latest update is about a missed opportunity for Green ICT purchasing. Click on the 'education' tag and you'll see more examples of Green ICT being applied educational institutions of all levels around the world..

Location is becoming increasingly important to the sustainability of ICT facilities. We've been tracking activities which try to leverage geographic features for greener operations. This article focuses on Europe and Asia. (Another focuses on North America.) Our latest update highlights the relationship between renewable energy availability and overall desirability for siting data centers.
