#47b - The Microsoft Azure dilemma with Holly and William Alpine - When enabled
emissions “offset” sustainability claims
October 29, 2024 • 38 MIN
They both went to this job interview to hone their skills, and got a dream job
at Microsoft! In its fast-growing and AI-pioneered Azure division. With a
romance on top of it… Yet several years later, they decided to both resign. Why?
On sustainability ground, and more specifically for the lack of support on
“enabled emissions” issues. Holly and Will Alpine are now the Bonnie & Clyde of
Azure and give us insider perspectives, in a nuanced and well-documented way, on
this “elephant in the room” about sustainability claims in all big tech
companies. In the final part of this 2-part episode, great insights were shared
on : 🤯 What is enabled carbon and why it offsets by far all Microsoft
achievements 😈 Devil is in the details from tailored solutions to
“carbon-neutral” oil company not following standard definitions of “net-zero” ✨
Can responsible AI principles really not mention anything about the environment?
⚖️ Why regulation will ultimately be needed ♀️✊ And … the Pussy Riot!

Velasco
March 12, 2024 • 52 MIN
🎙️In our latest episode, Hannah Smith, the COO of the Green Web Foundation, and

#31 - Estimating IT footprint: the ABB Motion case study with Fiona Leibundgut
and Thomas Mosser
January 30, 2024 • 54 MIN
How do we tackle the Green IT blind spot? 🏞️ In many big corporations, IT is
never number one, number two, even number three for GHG emission sources (and
other environmental factors). But everyone working in the digital sustainability
sector knows that, actually, little streams make big rivers with the digital
sector accouting for around 4% of global emissions. 📏 In this episode we
explore a very concrete case of measuring IT footprint in a massive corporation:
ABB Motion with Thomas Mosser (ABB) and Fiona Leibundgut (SparkIT Consulting).

scale, etc. And the insights shared can be used in smaller organisations as
well!
#30 - Can Digital Marketing be low-carbon? with Audrey Danthony and Diarmuid
Gill
December 19, 2023 • 59 MIN
0.9g of CO2e. It’s pretty ridiculous when you think about it. According, the
French SRI association this is the carbon footprint for a 10K prints digital
campaign with a 200k image. So not a big deal? Not that simple because we’re
talking about volumes in trillions per day here. So maybe it’s a good idea to
dive a little deeper on the environmental impact of digital marketing after all.
Hence we brought 2 experts in AdTech with a soft spot for Sustainability:
Diarmuid Gill is Criteo’s CTO since 2019 and has been in Digital Advertising for
more than 15 years. Audrey Danthony has also a long career in AdTech, she
started her first company, Oxeva, during the dot-com boom when she was still a
student at engineering school. And 2 years ago she pivoted and founded with 2
partners Impact+ with the aim of reducing Greenhouse Gas emissions in digital
advertising. ❤️ Subscribe, follow, like, ... stay connected the way you want to
