Ask HN: Does Europe Need a YC?

I see this being questioned by UK and Europe investors quite a bit. Does Europe needs a YC?Maybe, but first, a mentality shift might be needed...Instead of my inbox blowing up talking to lots of VCs, I’d rather to a few. Ones who have real-world experience. Someone who can actually add value, drawing on a portfolio of companies that offer traction, feedback, and support early on. Someone...

Market-based vs. location-based carbon accounting strikes again!

Does the market-based approach let Google claim lower emissions? If they’ve bought offsets or RECs, but it doesn’t reflect the actual grid mix at the time a prompt runs.

Location-based numbers give a truer picture of real-world emissions.

Apparently the internet frowns upon asking for upvotes directly.

So instead, here’s an interesting data point: shifting your CI/CD jobs to greener regions can cut emissions by up to 90%. If that’s worth an upvote somewhere,

I’ll let you decide where to click it ;)

Would love to hear your thoughts, especially if you've made region-level decisions for training infrastructure. I know it’s rare to find devs with hands-on experience here, but if you're one of them, your insights would be gold.
Saw some pretty eye-opening research from Verisk Maplecroft about rising climate risks for global data centres. Thought it was worth bringing here since a lot of us depend on multi-region infrastructure without really tracking these risks.

Key points from the report:

- Over 50% of the top 100 data centre hubs already face high heat and water stress risks. - By 2040, nearly 75% will be in extreme heat zones, with major jumps in cooling demand and operating costs. - Cooling already makes up ~40% of total data centre power usage, and that’s expected to increase sharply. - A typical mid-sized DC burns through 1.4 million litres of water per day for cooling. With rising temps, that’s going to get worse. - By 2030, more than half of these hubs will also be in high water stress areas, meaning not just cost issues but also risks of outages, or even political blowback from local communities.

Thought-starter:

Is anyone here factoring in environmental stress when designing multi-region failover or disaster recovery setups? Right now, most of us optimise for latency and cost, but it feels like these environmental risks are going to creep into operational reliability decisions, especially with regulatory pressures increasing too.

Tools like CarbonRunner.io that route workloads based on both carbon intensity and water stress data, turning off regions with unsustainable risk factors. Curious if anyone else is doing something similar or if this is still too early-stage for most teams.

We cut CI emissions by up to 90% – by choosing where code runs

We’ve been experimenting with running CI/CD jobs multi-cloud, across AWS, Azure, and GCP — but with a twist: each job gets routed to the lowest-carbon region available at the time (among other weightings like latency, performance, and provider preferences).There’s a surprising amount of variability between cloud regions. Some run on hydro, nuclear, or wind — others are still coal- or gas-heavy....

I've got a few questions about CI/CD-land and wondered if you could help.

This website is carbon-aware, changing its features based on live grid intensity.
