I was inspired to blog about my new car by a post on the BBC Ethical Man blog that @monkchips just tweeted. The slight irony is that the post is about how the author had his lovely Saab taken away to see if he could make it in the world without a car. And I’m about to tell you about my lovely new Citroen C1, which I bought so that I don’t have to catch the bus any more.

Typing that hurts slightly because I used to be so smug that we were a one-car household.

We (Tony and I) live in a village, and I work in another village. Public transport from villages in Hampshire to the cities isn’t that great; public transport between villages is worse. For a while, one of us would take the other to work but after trying both permutations of that arrangement, the fact that the two workplaces were pretty much opposite directions made the effort fairly pointless (in some ways was probably even a bit less green than if we’d each driven in separate cars because whoever was driving would end up in the morning rushhour traffic after dropping the other at work). For a while it worked with Tony catching the bus and me driving the car to my work – though this probably wasn’t ideal in terms of greenness because I was the only one in the car.

So, next, I was fortunate in that a couple of friends (who are also colleagues) car-shared their way past the end of my road every day and offered to include me in the arrangement too. That worked for a few months until a house-move by the driver meant that he would now be driving in the opposite direction from work to pick me up. So I finally tried the bus that ran through our village.

That was January 2007. Nearly two um three years later, I’ve finally given in and got a car. I did mandate to myself that it had to be rated at at least 60 miles to the gallon, and be as close to 100g/km carbon emissions as possible. Aside from a momentary wavering when I met Martin’s rather lovely Lotus Elise, I am proud to say that I stuck to that requirement (partly by telling everyone I knew so that I couldn’t slide out of it!) with my new 3.5yr-old C1 (60miles to the gallon; 109g/km). And it’s great – despite being a 1.0 engine, it’s only teeny so it’s very nippy.

So why did I give up the smugness of ‘being green’? Mostly (without boring you with joys of working across timezones) because I just couldn’t attend cross-timezone meetings and still get home by bus some days any more.

So how green am I now? Well, I really don’t know. I suspect that, in hindsight, the most ‘green’ arrangement I’ve tried was when I car-shared. When I was catching the bus, I wasn’t actually catching it every day because I did also get ad hoc lifts from friends too but bus was definitely my default transport for those two years. I’m actually not convinced that I was especially green for about 50% of the buses I caught – in terms of numbers of people on the bus, as the Ethical Man suggests. I have no evidence for this but I think the lift-sharing was probably greener.

So, I should/will probably start giving lifts to people who live on the way to work as long as my travelling times fit with theirs. Maybe I could/should continue getting lifts some days (and leave my own car at home) as I did before. I’ll have to see how it goes…

On a final, positive note, travelling with other people (whether by car or bus) is actually quite good fun and useful. On the bus, there’s a small community of regulars who usually say hello and notice when you’ve not been there for a while. Which is really nice, and I’ll miss that. Sharing lifts (or catching the bus with someone from work) is also really good because it gives me chance to catch up with the other person and find out what’s going on on their projects. It’s also been really valuable for doing reading or thinking. And it makes you get up on time and leave work on time.

Last year, after getting a Nintendo Wii, I wrote a post about its energy consumption and Nintendo’s place in Greenpeace’s electronics company rankings.

Greenpeace have updated their rankings…and Nintendo still holds bottom place. Pleased to see that Samsung and Nokia are still doing well (I have a Nokia phone and Samsung laptop and TV – part of my reason for going with Samsung was their green and ethical reputation).

I recently booked a transatlantic return flight for Tony and me with Virgin Atlantic. When you view your booking details on the Virgin website, they include a link to their carbon offsetting scheme.

A while ago, I wrote a blog post (Carbon off-setting) in which I described my current view (or near lack of) of carbon off-setting schemes. When I booked the Virgin flights, I didn’t immediately go for the carbon off-setting option because it pointed to a company I’d not heard of and, in a world of dodgy carbon off-setting schemes, how do I know they’re any different?

So I did a bit of research. I remember last year the UK Government (specifically Defra) identified four carbon off-setting companies that were kind of recommended but kind of not. Which is a reflection of the state of confusion customers are in. While I used Climate Care last year because that’s what The Co-op uses (and, apparently, The Guardian too), Climate Care isn’t one of the companies on Defra’s list, which means that it doesn’t meet Defra’s guidelines. But are Defra’s guidelines really that good?

I came across an interesting article in The Guardian from last summer. At the end of the article, it mentions a not-for-profit Gold Standard method which accredits carbon off-setting projects (renewable energy and energy efficiency projects with sustainable development benefits). This rang a bell with what I’d seen on the Virgin website.

Virgin Atlantic have set up a scheme with myclimate, a Swiss not-for-profit foundation, that customers can use to offset their flights. myclimate have several projects, including some that have already achieved accreditation by the Gold Standard, which is supported by several groups, including Greenpeace.

You can be cynical about an air travel company providing this kind of service – obviously it’s great for their image – but it does look as if Virgin have spent a fair amount of effort on it. They even provide a page explaining how Virgin calculates the carbon emissions of their customers (we’re travelling Economy – hence my titular smugness).

So, having read around a bit about the Gold Standard method of assessing projects’ effectiveness, I decided to go with Virgin and myclimate’s service. And I’ll probably use myclimate in future too (although there are other companies and not-for-profits that have Gold Standard-accredited projects as well).

I’ve finally just got round to carbon off-setting our flights for this year. I did do it a year or so ago but after that I read in New Internationalist magazine about the down-sides of carbon off-setting, I was less eager to just go throwing money at some company to asuage my carbon guilt and felt I should do a bit more research.

While doing some filing just now, I found the latest issue of The Co-operative Membership magazine, which has an article about The Co-operative Bank and its ethical policy. The Co-operative Bank apparently uses the Climate Care scheme to off-set its carbon footprint of things like business flights. I figure that The Co-operative Bank is probably a reasonably reliable role-model in such things so I decided to just get on with it and calculate how much carbon I contributed to the world by flying this year.

I’m sticking to personal flights here and not counting my return flights to the US at Easter for business. I need to look into what IBM’s eco policy is for such things.

So, sticking to personal flights, I think I’ve done pretty badly this year in terms of the number of flights I’ve made. Tony and I went on holiday to Paxos, a Greek island, in May, which involved return flights to Corfu. Also, I flew from Southampton to Glasgow for a wedding in June, although I virtuously caught the train back (I couldn’t take the day off work to get the train both ways). And Tony and I have another three flights between us between Southampton and Edinburgh for another wedding. On the plus side, we went to Brussels for a weekend in February using the Eurostar both ways – which was not only greener but actually quicker and more pleasant in my opinion.

According to the Climate Care calculator, all that comes to the grand total of £8.96. Which doesn’t seem very much but I guess that’s because they’re all fairly short-haul flights. I can’t remember how much CO2 that was but I’ll get my PDF certificate within 5 days to remind me.

So do I feel less guilty about my flights? I’m not sure. I don’t think so. I still feel it was an excessive number of flights to take – especially when it is actually possible to catch trains to Scotland (although the 7.5+ hours it takes each way from Southampton does cause problems if you’re going just for the weekend). I try to imagine what I’d have done if low-cost internal flights weren’t available. I guess I’d have either taken more holiday from work or just not gone to the weddings. I don’t think the availability of carbon off-setting would have featured very heavily in my decision. My reason for catching the train home when I went to the wedding in Glasgow was that I wanted to try to be at least a bit greener. I’m quite happy to sit on a train for an afternoon with a book, and it was actually cheaper to catch the train than to fly. I actually wouldn’t mind paying a little more to catch the train than fly so I felt a bit smug that I’d proved wrong all the people who claim that flying is cheaper than other forms of transport to travel long-distance in the UK. I’ve recently discovered, in travelling more frequently between Southampton and Lancashire, that you can actually get pretty good train deals if you book far enough in advance.

So, my position on carbon off-setting isn’t cut and dried. I think I see carbon off-setting as the last resort, after trying to find greener methods of travelling. I like to think that I’m making a bit of an effort in that (catching the train and Eurostar when it’s possible) but I know it’s not really as big an effort as it could be yet.

Last week, we replaced our old, 1970s Baxi back boiler with a brand-new shiny Worcester-Bosch condensing combi boiler. And thanks to the willingness of Sean Lidden, the boiler man who scaled our roof to install the vertical vent, the new boiler fits neatly into our roof-space storeroom.

When we first looked into it last year, we thought it would have to be mounted on an external wall. As we live in a narrow mid-terrace cottage, we don’t have a huge expanse of convenient external wall on which to unobstrusively mount a boiler. At best, we’d figured it would have to go in the computer cupboard (aka the server rack), which wasn’t really that ideal.

I guess it depends on the make/model of boiler but this is the make that Sean has used before because it’s easy to maintain and get parts, I think, and, for us, being able to vent it through the roof is definitely the best option. And being able to control the heating using a wireless thermostat/control means that we don’t have to make the trip upstairs just to override the timer settings.

So I worked at home for three days while it was all being installed. On the first day I had no heating or water (hot or cold) but a neighbour kindly lent me a key to use her facilities; after that, we had cold mains water but no heating or hot water. It was bliss on Friday evening being able to run the hot tap, and on Saturday morning have a hot shower.

The upshot is that we no longer have a hot water tank (and hence no airing cupboard), we have no cold water tank or header tank in the storeroom, and we have no ugly 1970s outset gas fire stuck to the chimneybreast. We have yet to decide what to put in the hole that the fire and boiler left behind but in the meantime, we can admire the pretty 1970s lime-green wallpaper that we discovered behind some formerly boxed-in pipes in the living-room:
