Last week I had the pleasure of interviewing Christopher Ong, Vice President Business Development, First Choice & GoGreen for DHL Asia Pacific , Eastern Europe, Middle East and Africa. The express division has cut its emissions by 19%, an impressive achievement given the large size of DHL. Globally DHL employs around half a million people.

How has it achieved these savings?

Firstly the chairman identified that it was important for the company to reduce its emissions, as part of being a good corporate citizen.
Secondly, it set a carbon reduction target, of globally reducing emissions by 30% per kg delivered, by 2015.

Third it put in place a measurement and tracking system. Unlike many organisations which centralise their data collection for the purpose of tracking emissions, DHL developed a system where the data entry is decentralised system.

Fourth it got staff using the system. Initially it was hard to motivate staff to do this. However with strong management support, monthly data entry into the system is now the norm. Each month each facility fills in a on-line questionnaire, entering in information such as the litres of diesel used. This only takes a few minutes.

Fifth, graphs and reports from the system are printed out at each facility, and put on the facility noticeboard where they are prominent to staff and drivers.

Sixth, it has fostered competition, encouraged ideas that reduced energy consumption, and empowered staff to take actions to reduce their energy use. For example, in their facilities in Singapore DHL now practices “lights off at lunchtime”, an idea suggested by a staff member.

Chris highlighted the fact that saving energy saves money, and that the Global Financial Crisis has actually accelerated their savings.  He said that their total savings to date of 19,000,000 kgs have come from lots of people each saving a few kgs each day. Financial savings so far total ten million euros. His advice to other organisations:

1. Be able to measure your emissions accurately.
2. Give power to the people on the ground. Give them the information they need – what their emissions are now, what they were, how much they have saved. The results can be very immediate, and this reinforces what more can be done.

DHL provide a inspiring example for other organisations to follow. This good news interview with Christopher Ong can be found at http://carbonetix.com.au/wwx/good-news-interviews.

After a $100 million smart grid trial in July this year, the Australian Government released the Australia smart grid guideline on the 30^th September.

“With this investment, Australia will showcase the world’s best practice when it comes to investing in smart grid technologies, helping industry get on with the job of rolling out these technologies and supporting clean energy jobs,” Mr. Garrett said.

The potential benefits of a full smart grid implementation are dramatic. Some studies have suggested that savings of between 10% and 25% in electricity demand are achievable.

In contrast, the USA Department of Energy delayed to reveal the smart grid standards last month. “Basically because the development of smart grids is a larger task than the electricity utilities can handle. There is also a lack of understanding and willingness by them to investigate how to best form partnerships with the rest of the industry.” Paul Budde posted.

This has not slowed some big names to rush into the market including Microsoft, Google, IBM, Cisco and AT&T, who are all eager to rock and roll.

My concern is the communication ability of smart grid and smart meters. At present, the meters only store 30 minute intervals of data and transmit the data bi-monthly or quarterly. If Australia has to replace all the electricity meters again after 5 years, who would pay for it?

What smart grids will Australia get? We will just have to wait and see!

You may have come across this news item a couple of months ago but it is worth taking another look. Although, the study was conducted by a major spam-ware corporation, it is clear that junk e-mails have a huge carbon footprint.

Anything powered by electricity emits greenhouse gases. Recently research was conducted in the US to find out the amount of energy needed to transmit, process and filter spam globally. The results were startling. According to the ‘Carbon Footprint of Spam’ report the average greenhouse gas emission of a single spam message is 0.3 grams of CO2. Is this a lot? Well, if you multiply this by the number of spam sent annually it translates into a huge figure.

It is estimated that there are 62 trillion junk e-mails sent each year. In terms of energy this equals to the energy needed to drive a car around the planet 1.6 million times. If looking at the electricity needed to power these spam it equals to 33 billion kWh. This amount of electricity could power 2.4 million homes for a year! Spam-related emissions for all e-mail users around the world in 2008 totalled 17 million tons of CO2 or about the same as the emissions produced by 3.1 million passenger cars. That’s 0.2% of the total global emissions.

The report found that about 85 to 91% of all e-mails globally is spam. Nearly 80% of the spam-related GHG emissions came from the energy used by the PC users viewing, deleting and searching for legitimate e-mails amongst the junk e-mails. But spam filtering itself accounts for about 16% of spam-related energy use. To view and trash a piece of spam takes about 3 seconds.

If every inbox were protected by spam filters, organisations and individuals could reduce today’s spam energy by 75% or by 25 billion kWh per year. This would save the same amount of greenhouse emissions as produced by 2.3 million cars. In late 2008 a major source of online spam was taken off line and global spam volumes dropped by 70%. However, there are always new ones to take its place.

This 8 minute video shows how Linfox is going about reducing its carbon emissions. What stands out for me in this video is the broad commitment across the organisation to cutting greenhouse gas emissions. Use it to help inspire a similar commitment in your organisation.

Reflecting on my interviews with various leaders in the energy efficiency space there are five things you must have to successfully reduce energy use and carbon emissions.

First you need leadership commitment.

Second you need a measurement and monitoring system. Whether you are a school (listen to Hannah Lewis, Westernport Secondary College, which has halved its energy use in the last four years) or a major corporation such as Wesfarmers, you must be able to track your progress.

Third you need more than one person active and driving the program. Witness Linfox, where a few programmers voluntarily took on the extra project of building a carbon tracking tool.

Fourth you need a well informed plan as to what you need to do. An energy audit by experienced energy efficiency engineers will provide this.

Fifth, you need investment. Money is needed to get the savings. The money could be spent on people (eg the driver training undertaken by LinfoX) or technology (eg lighting upgrades at Darebin City Council and Newcastle City Council, or the new paint plant at Toyota). 

Do this and with time you’ll have a self-funding system that will continue to reduce your energy use and carbon footprint.
