Don’t forget – where your cloud apps are hosted helps determine their carbon footprint

Back in July of this year (2011), the Carbon Disclosure Project (CDP), in conjunction with Verdantix, released a report titled Cloud Computing – The IT Solution for the 21st Century [PDF warning] which erroneously claims Cloud Computing is Green. Shortly after it was released, I wrote a long post outlining exactly where the report was flawed. I also contacted the CDP directly outlining my concerns to them and pointing them to the blog post.

Then, a couple of weeks back, when preparing my slides for my Cloud Computing’s Green Potential talk for the Cepis and Hepis Green IT conference in Athens, I discovered that Verdantix and the CDP had published

a new report [PDF] on the business and environmental benefits of cloud computing in France and the UK

Unfortunately, not only does the new report make the same mistakes as the original one, but it further compounds those errors with an even more fundamental one.

Let me explain.

In the key assumptions section of the report it talks about the metric tons of CO2/kWh in both the UK and French electricity grids (0.000521 tonnes and 0.000088 tonnes respectively). It uses these figures to extrapolate the savings in both France and the UK for companies migrating their applications to cloud computing.

So? You say. Sounds reasonable to me.

Well, the issue is that they didn’t do any work to identify where applications migrated to the cloud would be hosted. The implication being that UK applications migrated to the cloud, will be hosted on UK cloud infrastructure and French IT applications will be migrated to French hosted cloud infrastructure. In fact this would be a highly unusual scenario.

A quick look at where most cloud hosting takes place shows that the vast majority of it is occurring in the US, with quite a lot happening in Singapore with a lesser amount in Europe (and that split between Ireland, Germany, UK, etc. but almost none in France – Ireland is underestimated in the list as it doesn’t include Microsoft which has a significant Cloud hosting facility in Dublin which it is now expanding or Google’s Dublin facility)…

HP’s shrinking wallflower attitude may not be Sustainable!

HP CEO Léo Apotheker addressing the HP Summit
So I wrote a post the other day entitled Have HP’s senior executives lost interest in Sustainability? after attending a HP event in San Francisco. It was a little unfair because I concentrated on the lack of mentions of Sustainability by senior management on the first day of the event while leaving out the fact that I had interesting discussions with people involved in sustainability initiatives within HP the following day.

One of those I talked to at the event, Deb Lyons, was concerned enough by my piece that she went to the trouble of emailing me some of HP’s more impressive Green initiatives:

  1. HP published a fascinating paper [PDF] to quantify the carbon savings associated with switching from analog to digital printing and came up with a savings of somewhere between 114-251 MMtCO2 eq per annum (MMt CO2 is million metric tonnes of CO2) – similar to the savings which would be achieved by a broad implementation of lighting automation or extensive implementation of telecommuting!
  2. When printing is absolutely necessary, HP have comprehensive paper conservation and sourcing policies which include “a goal that 40 percent or more of the HP branded paper sold will be Forest Stewardship Council (FSC) certified or have more than 30 percent post-consumer waste content by the end of 2011″, an Eco Printing Assessment for customers and a reduction of paper shipped “in the box”
  3. While HP has yet to release its 2010 CSR report, its 2009 one is online and, in fairness, it is one of the better CSR reports produced by a tech co. (though it has a long way to go to catch-up to SAP’s 2010 Sustainability Report, which was released this morning!).
  4. I referenced the fact in my previous post that HP is becoming a devices company (between desktops, laptops, and more recently tablets and smartphones) so it is heartening to see HP have comprehensive policies around sourcing conflict minerals in Africa
  5. and finally, HP announced the other day that it had exceeded…

SAP’s Palo Alto energy efficiency and CO2 reductions

Cisco Telepresence

As mentioned previously, I was in Santa Clara and Palo Alto last week for a couple of SAP events.

At these events SAP shared some of its carbon reduction policies and strategies.

According to SAP Chief Sustainability Officer Peter Graf, the greatest bang for buck SAP is achieving comes from the deployment of telepresence suites. With video conferencing technologies SAP is saving €655 per ton of CO2 saved. This is hardly surprising given Cisco themselves claim to have saved $790m in travel expenditure from their telepresence deployments!

Other initiatives SAP mentioned were the installation of 650 solar panels on the roof of building 2 which provides for around 5-6% of SAP’s Palo Alto energy needs. This means that on sunny days, the SAP Palo Alto data centre can go completely off-grid. The power from the solar panels is not converted to AC at any point – instead it is fed directly into the data centre as DC – thereby avoiding the normal losses incurred in the conversion from DC->AC->DC for computer equipment. Partnerships with OSISoft and Sentilla ensure that their data centre runs at optimum efficiency.

SAP also rolled out 337 LED lighting systems. These replaced fluorescent lighting tubes and because the replacement LED lights are extremely long-life, as well as low energy, there are savings on maintenance as well as electricity consumption.

Coulomb electric vehicle charging station at SAP HQ in Palo Alto

SAP has placed 16 Coulomb level two electric vehicle charging stations around the car parks in its facility. These will allow employees who purchase electric vehicles to charge their cars free of charge (no pun!) while they are at work. SAP has committed to going guarantor on leases for any employees who plan to purchase electric vehicles. We were told to watch out for a big announcement from SAP in January in the electric vehicle space!
