Score Ratings

Our ratings are live updated scores from our primary research database. They are based on primary and secondary research across 23 categories - 17 negative categories and 6 positive ones (Company Ethos and Product Sustainability). Find out more about our ethical ratings


Score table

The score table shows simple numerical ratings out of 20 for each product. The higher the score, the more ethical the company.

Move the sliders to customise these scores. 

Click on a product name to see the stories behind the score (subscribers only). 


Full Scorecard

The Full Scorecard shows the 'black marks' for each product, by each of the 17 negative categories. The bigger the mark, the worse the score. So for example a big black circle under 'Worker Rights' shows that the company making this product has been severely criticised for worker abuses.

Scores start at 14.  A small circle means that half a mark is deducted, a large circle means that a full mark is deducted.

Marks are added in the positive categories of Company Ethos and the five Product Sustainability columns (O,F,E,S,A).  A small circle  means that half a mark is added, a large circle means that a full mark is added.

The Full Scorecard is only available to subscribers. Click on the More Detail link at the top of the score table to access it.

Best Buys

as of March/April 2011

As our ratings are constantly updated, it is possible that company ratings on the score table may have changed since this report was written.

Our Best Buy advice combines the total score on the corporate responsibility ranking table above with information from other areas of this report including: conflict minerals policy, supply chain workers' rights policies, elimination of PVC and BFRs and greener products.

Best Buys for desktops will be second hand where possible.

For new PCs, VeryPC, especially its Broadleaf range, and Aleutia are best. These are followed by the other low energy PC maker, Tranquil.

Next best will be the Dell Optiplex 980 range which cost around £600.

The cheaper Best Buy option is the ASUS Eee Box mini desktop models. They cost around £250.

Ethical issues in the market for desktop computers



Choosing a greener PC


Desktop computers can either have separate screens and keyboards or come as ‘All In Ones’ which combine the monitor into the same case as the computer, like the iMac. All In Ones are more portable than desktop computers but, like laptops, All In One computers are often characterized by a comparative lack of ‘upgradability’.


image: computer in ethical shopping guide



The top sellers


For desktops, about half of the UK market is in the hands of Dell, HP and Acer. Dell is the main supplier to households.

Despite having an almost tribal allegiance amongst its users, Apple products are not a big seller, perhaps because of their premium pricing (basic MacBook notebook starts at £867 from the Apple Store).


Climate footprint

Assessing the impacts of computer manufacture is a complicated thing and there is, unsurprisingly, some disagreement among different commentators. We currently favour the analysis of Mike Berners-Lee whose book about the carbon footprint of everything was published last year and therefore has the most up-to-date data.(2)

He explains that, even before you turn it on, a new iMac has the same carbon footprint as flying from Glasgow to Madrid and back.(2) That’s 720kg of greenhouse gases.(2)

Using the computer is a less significant factor. He says that the carbon footprint from use would equal the computer’s footprint from manufacture after 16,000 hours – that’s 10 hours every day for five years.

This is at odds with the EU Ecolabel’s life cycle analysis which states that energy consumed in use is the dominant factor.(1) The discrepancy is due, says Mike Berners-Lee, to the fact that the footprint of some of the complex processes has been missed out.(2) With the footprint from manufacture as the dominant factor, Mike Berners-Lee says it doesn’t make sense to buy a new, more efficient machine on carbon grounds. See ‘Reuse, repair...’ below for info about upgrading your existing machine.

But if you are choosing a new computer, it always makes sense to think about its power consumption.(2)



Low power consumption


The power consumption is largely dependent on what type of processor (CPU) is used in the machine. Our IT team, Open Plan IT, recommend you look out for low power processors such as the Intel Atom which also requires no fan so machines are virtually silent. The 'Thermal Design Power' is what you’re after. It ranges from about 4w for some of the Atoms and VIA processors to over 130w for some of the Pentium D models.

Our favourite website for checking power consumption of consumer electricals easily is Sust-it. 

When choosing a lower power machine aim for the best power consumption you can. As a guide, the following figures come from the sust-it website:

Desktop – power used when idle can range from 10W to 315W
Laptop – power used when idle can range from 5W to 22W
LED monitors – power used ‘in use’ ranges from 17W to 127W.



Using less energy


The amount of energy a computer uses is dependent on what the computer is doing. If you are playing games with graphics, charging or streaming video, then your processor will be working hard and be using more electricity than if you are just running a word processing program. But even when the machine is just turned on or ‘idle’, it could be using up to 100KW/h.(3) Computers apparently can use energy when connected to the power supply even when turned off, so it’s worth unplugging them at the end of the day or turning them off at the wall.(2) To minimise energy use the advice is to make full use of the computer’s power management tools (found in the Control Panel in Windows operating systems) so that it powers down and ‘hibernates’ when not in use.



Low energy desktop computers


According to VeryPC, the current typical desktop PC on the market consumes an average of around 115 watts. Three manufacturers of desktops in this report, VeryPC, Aleutia and Tranquil make computers that use less than 30 watts. They only make the base units so you’d need to buy a monitor, keyboard and mouse separately. Tranquil and Aleutia desktops are customisable so their price depends on your specifications.

VeryPC’s BroadLeaf PCs are BFR and PVC free and are Energy Saving Trust recommended. The basic model for home users, the Broadleaf BL43-H-i530 uses 24 watts when idling and costs about £600. It comes with a five year warranty as standard and comes with Windows operating systems.

Aleutia’s solar friendly PCs can run on a 12v DC battery. Its Di5 Core i5 PC is suitable for home use, consumes about 20 watts when idling and can come loaded with the Ubuntu open source operating system. It costs about £650 and has a one year warranty as standard. It can be bought on the Aleutia website.

An equivalent Tranquil PC model to the VeryPC Broadleaf (the ixLi 3 Power PC ) costs around £600 and consumes under 30 watts when idling. It has a one year warranty as standard and comes with a choice of Windows operating systems. You can buy it from the Tranquil website.




Sustainable products


There are now a number of competing certification schemes for more sustainable PCs. We outline each one briefly below. Greenpeace’s electronics campaigns (explained in more detail above) also rate highly a number of models which have achieved the most in harmful chemicals reduction.

Ethical Consumer has given extra Product Sustainability marks on its ratings tables to some of these models. We show below under 'Green Desktops' the specific models for each brand which have received these recommendations and why. We have included those models which were listed in January 2011. But be aware that not all manufacturers’ models are available in all countries and manufacturers discontinue models and bring out new ones all the time.

For our Best Buy recommendations we checked the availability of these green models and have not included ones which do not seem to be on sale anywhere. Those that were only available in e.g. the USA are thus indicated.



Energy Star

Energy Star is a voluntary US government energy efficiency program. The US equivalent of Which?, Consumer Reports, has criticised the Energy Star criteria as being too weak. About 25% of products in a category should qualify but many more than that usually meet the standards. Plus, manufacturers test their own products for compliance with the standards and there is no independent verification.

The Energy Star 5.0 standard recommends over 1,000 models of monitors and desktops and over 3,700 laptops – too many to list here. The TCO and EPEAT labels below use the Energy Star energy consumption criteria.



Energy Saving Trust

A UK government energy efficiency program, an Energy Saving Trust Recommended desktop computer will use around 40% less energy in a year than an average new computer.



EU Ecolabel

The criteria cover the life cycle of the product from manufacture to disposal and include energy use, limits on the use of hazardous materials and recyclability of the product.




TCO is a widely respected international eco-label developed by a Swedish trade union. It is a voluntary scheme which is third party verified. It uses Energy Star criteria for energy consumption, and a wide range of specific criteria for different products including limits on toxic chemicals and design for recycling. The TCO certification system also requires that the brand owner actively promotes social responsibility. It has a ‘Certified Edge’ label for those products it feels are at the cutting edge of environmental innovation.





EPEAT (Electronic Product Environmental Assessment Tool) is managed and operated by the Green Electronics Council, a US NGO. The label covers criteria for design, production, energy and materials use and recycling with ongoing independent verification of manufacturer claims after registration. EPEAT evaluates electronic products in relation to 51 total environmental criteria, 23 required criteria and 28 optional criteria. Products are then ranked by EPEAT according to three tiers of environmental performance – Bronze, Silver, and Gold. To achieve the Gold standard, products must meet all 23 required criteria plus at least 75% of the optional criteria. Most criteria deal with the environmental impact of the product and include meeting the Energy Star standard for energy use. But corporate performance criteria are also included.

US greener electronics campaign group, the Electronics Takeback Coalition, says that EPEAT is weak in many areas. Ethical Consumer has awarded and extra half mark for models meeting the EPEAT gold standard.

PVC and BFR free products

According to Greenpeace, some brominated flame retardants (BFRs), used in circuit boards and plastic casings, do not break down easily and build up in the environment. Long-term exposure can lead to impaired learning and memory functions. They can also interfere with thyroid and oestrogen hormone systems and exposure in the womb has been linked to behavioural problems.

PVC is a plastic used in some electronics products and for insulation on wires and cables. Chlorinated dioxins and furans are released when PVC is produced or disposed of by incineration. These chemicals are highly persistent in the environment and many are toxic even in very low concentrations.

Greenpeace has been campaigning on these issues since 2004 (see above) and its list of PVC and BFR free models is integrated into our recommendations below.



Green Desktops

Currently only the following VeryPC Broadleaf models of desktop are Energy Saving Trust Recommended: BL32-B-E53, BL32-B-E84, BL32-E-E53, BL32-E-E74, BL32-H-E53, BL43-B-i530, BL43-B-i661, BL43-Bp-i661, BL43-E-i530, BL43-E-i66, BL43-H-i530, BL43-H-i661, BL43-Hx-i661

Only ASUS has applied for and been awarded the EU Ecolabel for the following mini desktops which should be available in the UK: Mini desktops – ASUS Eee BOX models B208, B203, EB1002, B201, B202, B204, B206, EB1006

Only one company has applied for certification and met the criteria of TCO Certified Desktops 3: the Dell OptiPlex 980 range of desktops. They cost from £619 on the Dell UK website.

EPEAT Gold Label: Apple – 9 Macs, HP Compaq – 18 desktops, Lenovo – 21 ThinkCentre desktops.

Reuse, repair...


Because of the significant carbon footprint of making a computer, ideally the life of a computer should be extended by as much as possible. Re-using a computer can save up to 20% more energy than recycling.(1)

Repairing and upgrading is much easier with a desktop rather than a portable computer (because in the latter, most components are on the motherboard rather than separate). But even a laptop can have its memory or RAM upgraded (one of the most important upgrades you can do to a computer, according to our IT team at Open Plan IT). You can even do this yourself. Find out on the website how much memory your computer can take.

Another option is to buy second hand. Plenty of machines are available since a lot of offices and households replace their computers every two years.(1) You might be able to find some of the models listed in this buyers’ guide. Many computer retailers and manufacturers now sell second hand, reconditioned machines with warranties.

If you don’t want your old computer, you could donate it to a local organisation or charity. They all have minimum specifications for the equipment they will accept so check online.

Computer Aid International is a charity which provides refurbished computers for reuse in education, health, agriculture and not-for-profit organisations in developing countries. You can donate online.

Recycle IT! is a Community Interest Company providing training, paid work experience and real jobs for homeless and other long term unemployed people. They donate computers to charities and voluntary groups in the UK and abroad.

Computers for African Schools is a charity run by volunteers which provides computers to schools in southern Africa free of charge.

Donate a PC is a free ‘matchmaking’ service for individuals and organisations to donate un-needed hardware to UK charities, not-for-profit organisations and educational establishments.

There is also the option of donating it to another individual through sites such as Freecycle.



... recycle


And finally, if you can’t upgrade, repair or donate then you’ll have to recycle. The EU Waste Electrical and Electronic Equipment (WEEE) directive places a responsibility on computer manufacturers and retailers to provide or contribute to ‘takeback’ facilities.

Householders can:
• Ask a retailer if they'll take products back. PC retailers must provide free takeback facilities for customers to return old equipment for recycling whenever a replacement item is purchased. Some, such as the chain PC World, will accept old electronics in-store for recycling and reuse if you're buying a similar product.
• Take old computers to their local civic amenity site (visit to find your nearest recycle bank)
• Arrange for their local authority to collect the equipment (some local authorities provide a free collection service and others charge)
• Arrange for an electrical retailer delivering new equipment to take away the old equipment

E-waste is routinely exported by developed countries to developing ones, often in violation of international law, mainly because it is cheaper to recycle waste in developing countries. In 2003, in the UK alone, at least 23,000 metric tonnes of undeclared or 'grey' market electronic waste was illegally shipped to the Far East, India, Africa and China. In developing countries, there are few controls over the handling of the hazardous chemicals in e-waste. Recycling is done by hand in scrap yards, often by children. This issue was covered in more detail in our Buyers' Guide to Digital Cameras in EC124 (May 2010).

Reference 1 A Good Life – Leo Hickman, 2008




A complex machine for the digital age


The personal computer sits triumphant at the apex of modern consumer capitalism. It is probably the most complex single item that most of us have in our homes. More than two thousand materials are used in the production of the microchip alone – just one of the many components in each machine.(1) Each of these materials – many of them toxic – will have been mined or processed somewhere on the planet by other businesses.

Trying to make ethical decisions amidst all this complexity is a daunting task. Fortunately, in the four years since Ethical Consumer last looked at the computer industry, the number of civil society organisations working to address these issues has increased considerably. Whilst people are still a long way from being able to systematically measure and manage all the impacts of personal computer (PC) manufacture, campaigners have at least identified and focused their energies on the most urgent areas.

All this civil society activity appears to be having some effect – with transparency and reporting on social responsibility issues improving (albeit inconsistently) across the sector. Apple is perhaps the best example of this. The brilliant but spoilt child of computer manufacture had built a reputation of disdain for the general trend towards corporate social responsibility. However, as a result of high profile campaigning this has changed over the last few years, and its transparency – though still idiosyncratic – is now amongst the best. These changes, whilst welcome, are not the same as saying that the industry is, in any sense, humane or sustainable yet. 

The second point to be made is that, although regulatory and consumer interventions are helping to drive a reduction in the impact of each PC, there is a trend towards more than one PC in each household. Even if we halve the impact of use, if we more than double the number we have, then the overall impact is growing rather than falling.




Cultural pessimism?

“Perhaps the most disturbing environmental impact of computers, however, is the way they displace reality. Instead of the infinitely complex and genuine world of animals, plants and human beings, we are presented with a rarified and simplified virtual world that, however fascinating, is illusory...The hours and days spent on the computer are hours and days subtracted from our real lives – from real love and real adventure, and also from real heartache and real sorrow. Not only are they unreal; our computer lives are not the ones we dreamed of. When we think of the lives we really want to live, when we picture our heroes, we don’t imagine them spending their days sitting at a computer. Nor when we come to die will many of us look back and regret that we didn’t spend more of our time staring at a video screen.”

John Nolt, Professor in the Philosophy Department at the University of Tennessee, Knoxville.(2)

Profoundly impacting almost all aspects of work and leisure, the way people spend their waking hours has been transformed by the PC revolution in as little as twenty years. There is inevitably, and properly, some concern about where all this is leading. The New York Times reflected on a report that the “average person spends 8.5 hours a day in front of a screen” and the Daily Telegraph in the UK worried that “Children spend 7 hours 38 minutes a day online”.(3)However, it is a mistake to ignore the actual activities going on. If one person’s 8 hours were broken down, they might look like this: 2 hours spent reading/learning; 1 hour spent shopping; 3 hours spent working/selling; 2 hours chatting with friends or playing. Looked at this way, it doesn’t look too different to what humans have been doing for hundreds of years.

And the advantages of doing all this on computers are profound in that they allow us to have far more varied and complex interactions with people around us. On a remote Scottish island, for example, I can in theory communicate instantly with individuals all over the globe, either individually or with hundreds at a time – all in a very controlled and safe environment. There is actually very little real cultural pessimism around concerning computer use – and hundreds more people going online every day.

There are three real disadvantages though. The first is the sustainability of all this activity – the subject of moving global production onto a more sustainable path through our buying choices is the main focus of this report.

The second disadvantage is that there is emerging evidence that the sedentary nature of all this online interaction may (unsurprisingly) have negative health effects. A recent publication in the Journal of the American College of Cardiology found that spending more than four hour a day of leisure time in front of a TV or computer increased the risk of hospitalisation from heart disease twofold.(4)




The digital divide


The third disadvantage is that, as more and more human activity migrates online, the potential inequalities in society become more extreme. There are three main areas of concern here. A recent UK study showed that 25% of households had no PC and 29% no internet connection. This corresponded to 2 million children without internet access in an age where the correlation between owning home PCs and good educational qualifications were rising.(5)

The second social group where there are clear disadvantages in an increasingly online culture is older people. When we raised this issue in our email (!) newsletter recently, Rose Stockwell explained her position:

“Both my 90 year old parents run their lives, with increasing difficulty, without computers. Their banks keep telling them they can run their accounts online and get text messages on their mobile phones updating them on things. Additionally the banks are talking about no longer having cheque books...This is just a taste of the number of people telling them to do things online, which of course they cannot.
Mum gets frustrated because so often the alternative is to ring a number which inevitably leads to 10 minutes of listening to options – many of which mean nothing to her. And to add insult to injury I heard someone suggesting the other day that perhaps grandchildren or children could use their computers to do things for the grandparents. However, some things – like money – are often private.I think it is essential that all services remain able to use non-computer as well as computer systems, both for older people and for the times when there are power cuts and hacking or other disruptions.”

The third area of growing inequality is between rich western consumers and people in the Global South. At least 1.1 billion people are too poor to have access to this kind of technology.




Shifting power


As we mentioned above, computers are popular partly because they have increased the potential for human interactions exponentially. Indeed, amongst the pessimistic headlines in the Daily Telegraph recently we also discovered that: “Half of young people claim they are happiest online”.(6)

Most common though are commentators who point out how computing and the internet have shifted the balance of power significantly from big companies to ordinary consumers and, on occasion, to the civil society organisations which operate on their behalf.

Recent attention has focussed on, for example, the organisation of direct actions against tax avoidance by UK Uncut on Facebook. Others have pointed to the success of the global email campaign specialist Avaaz – which has won campaigns on issues as diverse as corruption in Brazil and the persecution of homosexuality in Uganda. Indeed, Ethical Consumer itself is an organisation which would not have been possible without the PC. Even before the internet, PCs were central to building our databases of companies, producing our publications and managing our customer lists.




Collective buying


The final key to making consumer culture more sustainable lies in the hands of businesses and governments by looking at their own purchasing of computer equipment. The EPEAT standard, mandatory for procurement of IT by all US government departments, is credited with driving better energy efficiency generally in the sector (EPEAT is covered in more detail below).

The European workers’ rights campaign group SOMO (covered below), is also doing work around procurement. It has a website at which gives some examples of best practice in IT purchasing amongst European cities such as Zurich and Stuttgart.

There are also a range of activities around the digital divide. One from Practical Action is an annual No-Tech Day which asks people to give up their gadgets for one day to think what life is like for people in the developing world. It is due to take place in June this year. I wonder how many of us will attempt this? And of those that do, how many will succeed?




Company behind the brand


Dixons Retail plc, the UK’s largest electronics retailer is an out of town centre shopping centre giant that owns Curry’s and PC World.(8) Advent Computers is the own brand of PCs for PC World, Currys and Dixons Online. Headquartered in Hertfordshire, it has subsidiaries in tax havens including Gibraltar and the Isle of Man. No publicly available information on policies such as the use of toxic chemicals and sourcing from the Democratic Republic of Congo (DRC) could be found. 

The Fujitsu Group failed to achieve a top score for environmental reporting as it only had its carbon emissions data verified by a third party. The company has a Nanotechnology Research Centre, for which it loses half a mark in the Pollution and Toxics category. It has been criticised for poor working conditions at supplier companies in China and Thailand.(1) According to the company’s website it supplies IT services and solutions to the Ministry of Defence and national security agencies.
