Gaël Duez (00:03 )
Hello everyone, welcome to Green IO. I'm Gael Duez and in this podcast we empower responsible technologists to build a greener digital world, one byte at a time. Twice a month on a Tuesday, our guests from across the globe share insights, tools and alternative approaches enabling people within the tech sector and beyond to boost digital sustainability.

This episode is a special one brought to you in partnership with Architect Tomorrow. These nine interviews were recorded live from Green IO London a week ago by Oliver Cronk, who I warmly thank for his collaboration. The sound quality isn't as good as you have been used to, but the quality of the guest is as good as ever. Enjoy the episode.

Gail, hi. Welcome to Green IO London, your conference that you put on all around the world. So I guess, you know, we wanted to recreate hopefully a little bit more professionally what we did last year. Hopefully with better audio, fingers crossed. Hence audio mic.

Speaker 2 (01:03 )
Pretty an amazing job last year.

Speaker 1 (01:05 )
So if you've not checked out last year's, can go and have a look at last year's. But yeah, what we wanted to do was give a little bit of a summary of what happened today at Green IO. So perhaps for those that are new to the Green IO brand and concept and thing, podcast, community, can you give everyone a quick summary? ⁓

Speaker 2 (01:20 )
Well, basically Green IO was created to connect responsible technologists. That really the main, I would say, North Star, even if I don't like that much single metrics, they can be very misleading, but the mission is there, like connect responsible technologists. And it all started with a podcast where I wanted people doing things in the green IT field. So really focusing on how to reduce my environmental footprint as a technologist, not focusing that much on the other part, which is how can I bring technology to do good things in the world because I believe that there are a lot of great materials, resources, podcasts, conferences, show, whatever about this, there is not that many shows and resources for technology saying, know, I'm every day at the office or behind my desk, what can I do? I want to reduce the environmental footprint, what can I do? And I realize that people in different line of works, whether they're design, ops, obviously, dev, et cetera, et cetera, things but they were not necessarily aware of what each other were doing and it's also happened across countries and even continents so it was like okay let's share the news and this is how the podcast was created and then two years ago, yeah two years ago now, I had the opportunity to partner with API Days who has been very committed in the field of sustainability, inclusivity, etc etc but all this I would say human centered and planet centered ⁓ fights and they offered me the opportunity to create my own conference within the big API Days conference and I said okay yes because I'm still a strong believer that in-person meeting is crucial. And the philosophy of these conferences were really based on three values, respect the planet, respect science, respect people. And what we do for this is we bring an international perspective, cross-disciplinary perspective. We connect people as much as we can because we do this meeting in person. And we respectfully agree to disagree. And that's really something that matters.
last year in London, I don't know if you remembered, you had on stage Mark Butcher saying that basically some tech companies were bullshitting, greenwashing, et cetera. You know Mark, old man yelling at the cloud. And a few talks later, one of these big tech company was explaining its own perspective and it was done respectfully. And so people in the room can have a healthy debate and understand, okay, I understand Mark's point of view, I understand this tech company point of view, I make my own opinion, but without yelling at each other, without this stupidness of a social media bubble and all of this.

Speaker 1 (03:59 )
Yeah, that in-person sort of communication is very important for that, isn't it? It's easy to get sort of, almost take away the human aspect of communication when it's online. But I mean, so look, Gael, you've taken this conference now all around the world. What is it about London and perhaps today that you're most looking forward to on the agenda?

Speaker 2 (04:13 )
I think we've been blessed to have, despite I wouldn't say communication embargo, but communication strict

requirements from their top management. A lot of the government's people joining, so we follow their rules, like there will be no Q &A, no interviews, no recordings, but they did the effort to come and to share what the civil servants have done in the UK. And to be honest, except for France, I didn't see that level of commitment anywhere around the world. think the UK folks are leading the charge when it comes to providing access

sustainable IT services for the population. They're very into it and I think we will have like maybe 50, 60, if not 100 participants coming from the civil sector. And that's great because my main goal is that when the average techie joining, not maybe Green IO, but like API Days or Generation AI conference or any other conference, when they see a Green IO conference, they might be curious

they might attend one talk and if this talk is the government saying we've done something when he or she comes back in the office and say hey boss you know I think we should do something about green up I think we should do something about sustainable design if the boss pushes back and say wow

that's green stuff, that's Greenpeace talking, we're doing business here. they know, actually the government has done it, or this big corporation has done it, or NHS has done it. Suddenly, it creates a lot of credibility and it can change the momentum internally.

Speaker 1 (05:52 )
Great. And so look, this episode, a special episode of Architect Tomorrow in collaboration with Green IO will give a bit of a... you so much No worries. I love this conference and I love what you do. It's amazing. And so hopefully this episode will give people a flavor of what was discussed. Clearly we probably can't cover much on the government side for those reasons that you just described, but I really hope there that people find this is a good introduction to Green IO and then they go and discover more.

Speaker 2 (06:15 )
would say that

will have lot of people doing GreenOps on a daily basis, achieving things. But I think this year seems especially interesting because it's good for the planet, good for business, question mark. And the question mark is important here. And this is all the juice of a green IO. Because we will have both people achieving great things with GreenOps,

Speaker 1 (06:33 )
Okay.

Speaker 2 (06:37 )
that's good to start. A journey needs to start. It needs to start in an accessible way. If you want to reach the star from day one, obviously it's a recipe to disaster. my point is, I think tomorrow what we will see is this dialogue between, this is what you can do on day one, but don't fool yourself. Don't fall in the

of greenwashing by pretending that because you started
