I wrote a medium post after AWS re:Invent 2022 summarizing the (lack of) news and all the talks related to Sustainability. The lack of progress on Scope 3 carbon reporting was picked up by Computer Weekly and the result was a statement from AWS that they are “working on it”. Google Cloud and Microsoft Azure released Scope 3 data in 2021. In their annual sustainability report in July 2023 AWS did update their list of sustainable regions to highlight 19 regions that are 100% sustainable — using an annual local market methodology for scope 1 and 2.

There hasn’t been any other visible progress, and most of the people I used to work with on sustainability have now left Amazon. For re:Invent 2021 my team (but mostly Elise Greve) persuaded the re:Invent organizers to include Sustainability as a track code, and that was repeated for 2022 and now for 2023. I reported on the keynotes and announcements in real time using the #reinvent tag via my @adrianco@mastodon.social account, and as I get a chance to watch the track sessions, I’ll update this post with my thoughts. I’ve added all the videos I could find, but they are still being posted so some are missing and I’ll check again later.

Energy Project Updates

AWS are targeting 100% in-region renewable energy by 2025 and were at 90% globally in 2022. This is an annual net energy market methodology, and I’ve talked elsewhere about exactly what that means and how that compares with other cloud vendors. Their policy is a good one and they are investing at a very high level, as the largest commercial purchaser of renewable energy globally:

We aim to have 100% of the electricity that we use to be attributable to renewable energy sources. We contract renewable power from utility-scale wind and solar projects that add clean energy to the grid. Many of these projects are enabled by long-term contracts such as power purchase agreements for large projects in the same energy grids as our electricity use.

The AWS list of energy projects was quietly updated just before re:Invent, to add a bunch more, but it wasn’t mentioned in the conference keynotes. The AWS Energy team was represented by Abhishek Sharma’s SUS101 talk (video embedded in the list of talks below) that provided the basic AWS messaging, largely unchanged from when my team created it in 2021. He updated the Amazon public committed renewable energy generation project total from last year’s “over 20GW” to “over 26GW”, and reported good progress on the water usage commitment they made last year. The projects on the website aren’t a complete list, as I’ve heard that there are some that never get announced, and they are a mixture of rooftop solar and utility scale solar, wind and battery, distributed over Amazon retail, Amazon devices, and AWS. I’ve extracted the underlying data from the Amazon map display that includes rooftop solar etc, and the public AWS utility scale energy capacity list adds up to over 18GW, with excellent global coverage. The difference between 18GW and 26GW is capacity dedicated to non-AWS parts of Amazon, which is growing rapidly as the delivery fleet and fulfillment centers decarbonize. Amazon has more capacity over-all and much better global PPA coverage, including Japan, Korea, Indonesia, India and China, than Google Cloud and Microsoft Azure, who have very few PPAs in Asia. The projects are tagged by date, and some are coming online in future years. AWS policy states that they may buy unbundled renewable energy credits on the open market, and in particular in locations where they have a committed project that isn’t online yet. I think this is a good policy for limited use of RECs. I plotted the AWS capacity over time, which shows the rapid ramp up in delivered capacity and future commitments over the years:

Keynotes

Peter deSantis did a Monday evening technology keynote that usually has most of the sustainability related content in it. I expected an update on their water sustainability program that was announced last year, and a new number for the amount of private purchase agreement (PPA) power that Amazon has under contract. Peter had sustainability as an issue on one of his slides but didn’t mention or announce anything.

The main keynote by Adam Selipsky spent a lot of time on generative AI, but also didn’t have any mention of sustainability topics.

Werner’s keynote talked about sustainability, but only from the viewpoint of using cost as a proxy for optimization. This is pretty weak, as a dollar of CPU and a dollar of storage have very different carbon profiles, and customers need better ways to model and estimate actual carbon data in real time. There was a lot more more useful carbon optimization information in Steffen Grunwald’s SUS302 talk.

Some of my favorite people at AWS, VPs Bill Vass, Francessca Vasquez and David Brown gave Innovation keynote talks that are worth watching.

Sustainability Track Sessions and Workshops

What follows are the catalog descriptions of the talks, after I’ve watched each of the videos I’ll update this post with my own commentary.
