Several years ago, my employer was constantly talking about Net Zero/Carbon Neutral so was talking about reducing energy costs and planting trees. I think part of it is just “smoke and mirrors” as they were shutting down some data centres but then moving it to the Cloud, so the servers are still there, it’s just someone else’s problem.
The other aspect of why it’s all nonsense is how they always talk about using AI for everything but this is notorious for increasing energy usage.
I think it’s just the usual virtue-signalling propaganda.
We should all be aware that sustainability is high on our agenda! Living in an increasingly digitised world and working in the technology industry, I feel we should all be mindful of how much of an impact our digital activity has on the world we live in.
from UNICEF: Five tips for reducing your digital footprint.
Did you know that a typical year of incoming emails adds 136 kg of emissions to a person’s carbon footprint, or the equivalent of driving 320 kms in an average car. Digital pollution is the greenhouse gases that come from building, delivering, and using digital technology. It makes up 4 per cent of the world’s global greenhouse emissions – double that of the global aviation industry – and this number is growing exponentially as our way of working and living becomes increasingly digital.
Topics we have been exploring:
- Reduce energy consumption of devices – Energy is the dominant contributor to climate change, accounting for around 60 per cent of total global greenhouse gas emissions.
- Do we all shut down our laptops when not in use for long periods of time?
- Should we make sure we close programs that we aren’t using?
- Could we consider reducing the screen brightness?
- Do we always leave devices plugged in at full charge? It might be better instead to charge for short and regular intervals as this also increases the battery life.
- Reduce our use of email – As the above quote highlights emails contribute massively to digital waste.
- We shared tips of how to reduce emails –
- Do we need to ‘reply all’?
- Do we need to send an email at all? Could internal conversations be held on Teams instead?
- Could we make use of emoji reactions for internal responses?
- Does the email need an attachment, or could we use a link to a shared online file instead?
- We looked at ways to reduce emails in our inbox and make it easier to tidy up.
- Do we have lots of emails that could be deleted? It’s possible to set filters to sort specific types of emails into folders and use auto-archiving settings to delete them at specific time intervals. This is particularly useful for our team where we have lots of automated emails which we don’t need to store for long periods of time. Creating rules to automatically delete these would make it easier for us to manage.
- If emails need to be kept, could these be archived? This may be useful if they don’t need to be accessed often. Storing them elsewhere may mean less energy is used when loading Outlook and searching through emails. There are auto-archiving features to make this simple and less time consuming too.
- Do we always unsubscribe from any emails we don’t need or want? The safest way to do this is to log in and adjust notification settings on your account e.g. unwanted reminders and adjusting Teams settings. When discussing this topic, it is worth reminding everyone to always be vigilant of the potential for any email to be a phishing attempt and not to risk clicking on any links from unknown senders.
- Clean up old files – Data that are stored online take space on servers that require energy to be active 24/7.
“Whether it’s meeting our net zero targets, creating an inclusive working environment, or having strong and ethical governance practices – sustainability in all its forms helps drive us forward as a business and forms a key part of our strategy.”
We were encouraged to set a personal objective for the year based on Sustainability.
Suggestions include:
- reducing your carbon footprint (through e.g. reducing your business travel or digital footprint)
- volunteering with your local community using your paid volunteering days
- championing equity and inclusion in your role, ensuring accessibility is considered in any output or practice
- becoming an active member of an employee-led group or the Sustainability Community of Practice’
Even the Software Development process is sustainable. Really, it’s just more corporate buzzwords and meaningless jargon.
Sustainable Software Development lifecycle
There is a comprehensive reference architecture on Confluence covering account structures, principles, application architecture, data architecture, security architecture, standards & templates, sustainability, app launch, EDA and more.
The tech strategy and architectural runway is fully documented on Confluence covering all core technology and platform services, components and enablers. It is future proofed and covers all investment case technology needs, and product roadmaps.
Environmental Sustainability is close to my heart and is a critical strategy as we work towards Carbon Net Zero by 2040.
Closing Thoughts
I think the claim to be Carbon Neutral is mostly virtue-signalling and although they might come up with some schemes to reduce carbon emissions, it will mostly just be a box-ticking exercise and can just move the problems elsewhere. So the field staff may well have electric cars, and most people work from home. But since we aren’t just heating a single office, but hundreds of homes now; then we probably are using more energy overall. Then everyone is using AI for simple communication.
