How to reach ESG goals ?
Hi ,
Like many companies we have an ambitious goal to reach reach net-zero GHG emissions by 2040. Without no surprise to anyone datacenters , campus and branches do contribute to a big chunk of these GHG emissions.
I would like to hear about your creative solutions to reduce energy consomption !
Port schedules to turn off APs during the night ? Weekends ?
Remove unused/dormant switches
Optimization of stacks ( eg : a stack of 5 switches could be moved/transformed to a stack of 4 switches )

The ones you @RaphaelL are already likely familiar with and using already:
1. Turn off APs at night/weekends
2. Turn off/disable unused ports
3. Turn off PoE for ports NOT being used
Beyond that, I too would be interested in what others are doing!

In the past I've swapped out PCs for Chromebooks and thin client terminals.
A more modern trend could be to use SharePoint365 instead of on premises file servers along with lots of SaaS. However that's just moving the problem elsewhere...
I have also swapped Intel Xeon servers for AMD Epyc as they used a lot less power along with replacing hybrid SANs with Pure flash arrays.
On the Meraki side moving stacks from dual PSU MS models to C9300s with power stacking and therefore fewer PSUs could help.

Consolidation and rationalisation. Currently working on a project where I’m looking to remove nearly 30-35% of the switching estate due to underutilisation. Complete waste but has been left to run like this for years.

I'm not an employee of Cisco/Meraki. My posts are based on Meraki best practice and what has worked for me in the field.

Also look at WiserWatts from CAE to see what they’ve been doing in this space.
reach out to @Alisdair, @Alisdair85 if you want to learn more. Not sure why theres two profiles.

We are on the same boat. We used to have large stacks per floor ( 7-8 switches ) back in the days every user had a desktop. Now with everyone on laptops and physical Cisco phones removed many many many of our switches are dormant.

Thanks for the tag @DarrenOC! 🙂
@RaphaelL I'm happy to support a conversation here, no costs involved as it's just an area I'm passionate about and keen to support others to drive an environmental impact change. This is a topic ('sustainable networking') and R&D space that my dev team and I have been driving hard focus on for coming up to 4 years and developed productised Meraki API integrated solutions to make the process easy with a focus on four use cases, but also plugging gaps in the Meraki platform (and anomalies in usage data) to enable better support with automated energy management and reporting.
I agree with you both, from the analysis of nearly 400 customer network environments that one of our platforms reports on every 24 hours shows a clear trend regarding ports utilisation, nearly all have at least 1/3 to 2/3 of an underutilised Campus/Branch environment, some into the 10's thousands of switchports, but its great to see many starting to make changes by using the data we provide at no cost so they can make informed rationalisation/consolidation decisions, like the below from a popular global brand across thier offices over the past few months - removing 1,000+ unused ports...
On powering down PoE devices, I did an exciting post on this on Friday below, we are powering down over 10,000 PoE devices each night which is saving close to 200,000 kWh this year.

Below is a collection of different content pieces from this past year that I’ve either done with Cisco Marketing or authored.
Cisco joint collaborations over the last 12 months in the Cisco ‘sustainable networking’ space:
- Wrexham Council - Rethinking IT infrastructure to reduce cost and carbon emissions across 70 schools
- Cambridgeshire County Council / ICT Service - Cisco partners with Cambridgeshire schools to make their classrooms more sustainable
- Cisco ISG Schools Sustainability webinar with IT Leader from Wrexham Council: ‘Helping schools achieve their sustainability goals and save money, with Cisco Meraki’.
My content:
- WiserWatts solution overview
- Short Whitepaper for the Education Sector - ‘Policy-driven energy management for sustainable schools: How to reduce energy waste in your school or college.’
- 5 carbon-reduction tips for a sustainable and efficient workplace
- Smart strategies to cut business running costs and streamline your operations
- Short Whitepaper: 'Moving away from an always on culture'
- Achieving Digital Transformation and sustainability goals simultaneously

Oops, forgot one:
- set MS AD GPO for client PCs to sleep after X min of inactivity. Servers are not part of this energy saving process.

We've gone 100% work from home. No more people using vehicles to go to work and back each day. No more office.
