Benefits of greeNsort®

Get huge money, time, hardware, energy and CO2 savings by switching to lean greeNsort® algorithms.


Why using greeNsort®?

Elementary building blocks of computing are far from being perfect. They waste lots of memory. They waste unnecessary operations in nearly every step.


How does greeNsort® work?

greeNsort® makes computing smart again: by using less memory and removing these unnecessary operations you obtain the same results faster.


greeNsort® is risk-free, quick and cheap!

greeNsort® has successfully developed sustainable algorithms over the last 10 years. A relevant fraction of the greeNsort® savings can be realized just by pluging-in these algorithms into the central sorting libraries of the 15 most important programming languages.


greeNsort® provides huge savings!

The annual worldwide savings potential of greeNsort® algorithms is 51.3 TWh resp. 30.3 MtCO2e, this corresponds to 4.3 large-scale power plants1 or a public value of 7.1 Billion EUR.2


greeNsort® needs support!

If you are a government, a foundation, a cloud-provider or a private philanthropic sponsor looking for a climate-protection-investment-opportunity with an extremely good ROI: please see Next Steps.

If you are able to help with coding or in a position to influence standard libraries please see Actions.
