Sustainability statement
Summa Networks is committed to sustainability from the ground up — it is an energy-efficient company by design. The telecom industry represents 3% of global energy consumption and carbon footprint. Within that, while the Radio Access Network (RAN) accounts for approximately 73% of energy consumption in telecom networks, the Mobile Core — where Summa Networks operates — represents only 0.06% of the energy consumption within the telecom sector.
When it comes to our energy-efficient software production, we design and develop our solutions in ways that optimise hardware and energy resource usage — implementing efficient algorithms, optimising code, and responsibly utilising system resources, all of which reduce the burden on hardware equipment and minimise energy consumption.
We focus on producing software that minimises resource consumption — including CPU, memory and disk usage — ensuring efficient operations while reducing environmental impact.
With no physical office, we prioritise remote work — reducing our carbon footprint, minimising commuting emissions, alleviating traffic congestion and air pollution, and promoting a healthier work-life balance.
We use cloud services for our processes, our internal servers are located in data centres with green certification, and all our code resides in secure cloud systems where we rely on green initiatives by Hyperscalers.
