Our hands aren’t clean Global electricity consumption = 21,000 TWh 1 in 2016. Est. global energy consumption for data centers & enterprise networks alone was 245 TWh in 2016. 1 ICT networks (phones + computers) add another 220 TWh. 1 @a_meba Norway Iran IT sector USA China 100 200 300 6400 TWh 400 6300 … 4000 3900 3800 … 3700

Let’s simplify it a bit (Conservative) assumptions: ● The IT sector produces well over 110 Mt CO 2 equivalent every year.1 ● We can spend 20 years on offsetting a year’s emissions. ● A tree can absorb ½ ton of CO 2 in that time.2 ● we fit 100,000 trees in a km2. @a_meba

Not all cloud providers are the same @a_meba ● Some create efficient data centers with a PUE (Power Usage Effectiveness) way over the industry average.1 ● Some either use renewable energy or match actual energy demand with carbon-free supply. ● Some implement a circular economy and reuse server components. @a_meba
