I've been thinking for a while how to keep myself motivated in efforts to improve the environment. I'm going to try and post once a week with something I've done for the environment that week.

It could be anything: writing a letter to a politician, fixing a performance problem in some software, planting a tree. It'll probably be small, but hopefully it'll be something.

Feel free to ignore (filter by hashtag), or to pick up on the ideas. It's mostly for my own motivation.

#EnvironmentThisWeek

This week I finally finished off insulating the loft of my house, bumping its insulation depth from 250 to 400mm.

It's a job I started a long time ago and kept putting off because it's itchy. It's actually fine with a decent face mask and gloves though. The heat loss through the loft is now down to about 4W per degree difference in temperature between inside and outside (U-value 0.11W/m²K), which is good.

#EnvironmentThisWeek

This week I planted 11 horse chestnut trees somewhere locally to me. I’ve been growing them in pots for 2 years, from seed (nut??) and now they’re about 20cm tall they’re ready to plant out. It took about 2 minutes per tree.

#EnvironmentThisWeek

This week I spoke to my county councillor about cycling provision and protected bike lanes on some of the busier roads near me. The conversation wasn't anything new, but useful to keep things on the radar.

Better cycling provision is important for modal shift away from private car use.

#EnvironmentThisWeek

This week I didn't manage to do anything for the environment, as I was doing DIY all week.

Part of what I was doing was increasing shading on the south side of my house, to reduce overheating in summer. I guess that's climate-change-adjacent. I added a small lean-to roof over a door/window.

#EnvironmentThisWeek

This week (erm, last week), I wrote to my local councillors about light pollution, asking if they could more widely adopt dark skies lighting principles as part of planning policy.

https://www.friendsofthelakedistrict.org.uk/lighting-policy

This would reduce energy consumption, give insects and birds better sleep, and give us better sleep too.

The advice/policies for this are quite well developed now, so should be straightforward to adopt. Let’s see if there’s the political bandwidth.

#EnvironmentThisWeek #LightPollution

Light Policy and Guidance

Cumbria Good Lighting Technical Advice Note To conserve and enhance our dark skies and contribute to a net reduction in light pollution across Cumbria, it is vital that we are all informed and empowered to make good lighting choices when planning new development or installing new or replacement lighting.  As part of the Dark Skies Cumbria Project, Friends of the Lake District, together with Dark Source Lighting Design Studio and in conjunction with the relevant local planning authorities, has produced a Good Lighting Technical Advice Note (the TAN) covering Cumbria, the whole Yorkshire Dales National Park and also the Lancashire part of the Arnside & Silverdale National Landscape. On completion in Summer 2023, the TAN won both Platinum and Green Build Back Better Awards. It has also been shortlisted for a Royal Town Planning Institute award.  The TAN provides technical lighting guidance to planners, appli­cants, architects, developers, electricians, property owners, communities and lighting professionals to support them in applying relevant local and national planning policies and good lighting principles when submitting or assessing plan­ning applications or other applications (such as Notifications of Intent and Listed Building) and in making good lighting choices when installing new or replacing existing lighting outside of the planning process.  The guidance covers:  The importance of Dark Skies to Cumbria;  The 8 Good lighting principles;  Positive lighting outcomes delivered through getting lighting right;  Different forms of light pollution and their impacts;  The role of the TAN in the planning process;  The planning and lighting design process;  What good practice looks like through visuals and examples;  Relevant background information in technical appendices, including a Glossary, ‘Understanding Light’ and reference/further reading list. Supporting Documents: Technical Advice Note (TAN) - Full Version (Issuu) Technical Advice Note (TAN) - Summary Version (pdf) Eight Basic Good Lighting Principles (pdf) Eight Basic Good Lighting Principles (print friendly pdf)

Friends of the Lake District

This week (er, last week again, I need to get more prompt with these toots) I collected several hundred grams of plastic litter from a local moorland and organised car sharing for a holiday with my friends.

#EnvironmentThisWeek

This week (ha, last week) I continued the conversation with my local councillor about light pollution, and he gave me several contacts to get in touch with about some policy proposals

#EnvironmentThisWeek #LightPollution

This week I did a point to point running race and organised to get back to the start by public transport. (Most people arrange to have a friend drive and collect them.) The train ride back to the start was very scenic and relaxing.

#EnvironmentThisWeek #PublicTransport

This week (well, this weekend, which is ending for me now as I type this on a train) I combined cycling and trains to get across the country to see some friends. Everyone else who came drove. I got some work done on the train, and some good exercise and fresh air on the 200km of cycling. It took a while though.

I’ll try and do something more interesting for the environment in coming weeks. I realise these updates are boring.

#EnvironmentThisWeek #PublicTransport

This weekend I sorted out all the mixed rubbish from our weekend away of 8 people. 10g had to go to landfill, the rest (about 3kg) could be recycled or composted.

I’ve lost the link, but last time I looked this up I think the emissions from landfill were on the order of 1kgCO2e/kg of waste

#EnvironmentThisWeek #composting #recycling

This week, due to continued dry weather in the UK, my plants needed watering. I watered them from water butts (and have been doing for weeks now). I’ve got 300l of capacity, and it’s now almost empty because of this extended period of dry weather.

If you’re in England, you can likely get discounts on water butts from your water supplier. (For example, https://www.savewatersavemoney.co.uk/products/garden)

Last week, I managed to spend a bit of time at work pushing forward some performance improvements to software. Not big improvements, but improvements nonetheless.

#EnvironmentThisWeek

Last week, I car shared to a local fell race one evening. Meant a slightly longer travel time, but far lower emissions and much less parking congestion. This should be the default.

#EnvironmentThisWeek #fellrunning

Last week, I started the process of getting environment statistics recorded for #GUADEC2025. For the past few years the sysadmins have kindly recorded server usage data (for streaming, remote participation, etc.) and the organisers have kindly included travel questions in the post-conference questionnaire.

This data has been valuable to quantify the #GNOME project’s environmental footprint, and comparing it between years (and different models of conference organisation).

#EnvironmentThisWeek

Last weekend, I helped a friend replace the fixed anchors in a local cave, as they were loose. We could have just put new anchors next to the old ones, and saved a lot of time, but instead we drilled out the old ones and re-used the holes to resin in the new ones. This avoided damaging the surrounding rock further than it already is.

#EnvironmentThisWeek #caving

This week I took some old laptops and tablets off some friends, in order to wipe and reuse/recycle/strip them for components, to get more life out of them. I haven’t assessed what state they’re in yet, but hopefully a few of them can have a second life in someone else’s hands.

#EnvironmentThisWeek #reuse

This week I replaced the tap nozzles in a building I help maintain with Neoperl low-flow aerator ones. Same efficacy for washing your hands, but about half the water usage.

(Also, several days early in posting this! Might make up for some of the times I’ve been late.)

#EnvironmentThisWeek #WaterUsage

This week I repaired a kitchen cooker extractor hood where the motor had died. One new motor needed, but most of the hood could stay in place.

#EnvironmentThisWeek #repair

This week (ha, I’m early again!) I spent a few hours removing Himalayan balsam from a local area before it sets seed and smothers out more other plants.

Had a few nice chats with people who went past and asked what I was doing.

#EnvironmentThisWeek #HimalayanBalsam #InvasivePlants

This week just gone I did more balsam removal. That might be all I do for the next week or two, trying to get as much as possible before it sets seed.

#EnvironmentThisWeek #HimalayanBalsam #InvasivePlants

This week just gone I litterpicked two old foil helium balloons from a moorland, at 500masl. They float away from whatever party/funeral they’re at, slowly lose buoyancy, and come to rest on a moorland fence ready to spread plastic everywhere.

#EnvironmentThisWeek #litter #moorland

This week I repaired a second-hand belt sander; all it needed was a couple of replacement bearings, which were very standard. Avoided this going to landfill.

#EnvironmentThisWeek

This week I repotted about 50 oak saplings I’ve been growing, as they’ve now outgrown their tiny pots and are off to big plant pot land.

Hopefully maybe half of them will be ready to plant out in the big scary world this autumn. We’ll have to see.

#EnvironmentThisWeek

This week (well, last week) I took the bus to go camping for the weekend, even though taking the car would have been easier. Got to read a book on the bus and generally have a much more relaxed time.

#EnvironmentThisWeek

This week (ahead of schedule!) I fixed the dodgy right-click button in my mouse with a new microswitch, rather than getting a new mouse.

#EnvironmentThisWeek #repair

This week I provided feedback (OK, complaints) about news coverage given to different political parties in one article, and about how to cool a house down in another article.

If you’re going to write an article about drilling for oil, maybe don’t put the quote from the Green party right at the bottom.

If you’re going to cool a house, there are much less energy intensive ways to do it than air conditioning.

#EnvironmentThisWeek

Last week I fixed a dodgy connection in some small consumer electronics (a night light) which meant it would otherwise have been thrown away.

#EnvironmentThisWeek

Last week I spent a few hours planning for increased water storage capacity (both potable and grey) for a remote building which has suffered from drought on its spring fed water supply in recent years.

#EnvironmentThisWeek #ClimateChange

Last week I had a friend stay over so we could go to a fell race together, allowing him to get there by public transport. It helped as the parking field for the race was small and quite slippery. I still could have done better at lift sharing though (two spare spaces in the car).

#EnvironmentThisWeek #FellRunning

This week I persuaded some friends to borrow or hire a decent quality tool rather than buy a cheap one for one week of work (and it inevitably get binned afterwards).

#EnvironmentThisWeek #tools

This week I did all my baking for the week during a 2h period of super-low-carbon electricity in the UK’s grid (due to windy weather). Low embodied carbon cakes, and also free electricity 🥳

#EnvironmentThisWeek

I’m quite behind on this. On the week of 2025-10-06, I was doing building work all week, so didn’t do much for the environment. We did experiment with lime plaster, though, which is a common heritage building material, so tangentially environment-related. It took ages to dry.

#EnvironmentThisWeek #LimePlaster

On the week of 2025-10-13 I sorted out the rubbish from a large party, ending up with 99% recycling, and (literally) a handful of stuff to go to landfill.

#EnvironmentThisWeek

This week I’m going to Northern Ireland, but taking the short ferry (from Cairnryan) rather than the long one (means lower carbon emissions from ferrying), getting to the ferry by train, and taking my bike for getting around when I’m there.

I think that’s pretty much the lowest carbon way to get to NI, and it should be good exercise

#EnvironmentThisWeek

This week is basically the same as last week: I’m travelling around (sort of on holiday) by bus and foot. Decided not to bring my bike in the end; too rainy to be fun for the time I have.

#EnvironmentThisWeek

This week I chose to have a parcel delivered to a local shop for collection, rather than my door. Reduces the miles for the delivery vans, and forces me to go out for a nice 15min walk to pick it up. Win win.

#EnvironmentThisWeek

Last week I car shared to two fell races, and combined one of those trips with a visit to several shops and the recycling centre to reduce my traffic miles. Small things.

#EnvironmentThisWeek

This week I planned out tree planting for this planting season, and got hold of some tree whips in preparation. Not very much, but some progress.

Despaired at COP for a bit.

Donated some money to Yorkshire Dales Millennium Trust for tree planting, as they have a double donation week. https://donate.biggive.org/campaign/a05WS000008zzWbYAI

#EnvironmentThisWeek

Let it Grow – Big Give

Double your donation for woodlands during #NationalTreeWeek and make twice the impact on the environment this Christmas! We need your help to create and care for our wonderful woodlands in the Yorkshire Dales. Give a lasting gift to nature and let it grow for generations.…

This week was similarly unproductive, mostly due to having a cold. Moved some 2-year old saplings out to a sheltered spot near where they’ll get planted so they have some time to adapt to the weather there, but that was it.

#EnvironmentThisWeek #TreePlanting

This week I planted out the 200 tree whips on a blissfully nice morning. Good to get outside after having a cold.

#EnvironmentThisWeek #TreePlanting

This week I arranged several in-person meetings to all happen in the same place on the same day, saving about 60 miles of travel.

#EnvironmentThisWeek

This week infracost.io released an implementation of a feature I requested to show carbon emissions from your cloud service usage. 🥳

https://www.infracost.io/blog/shifting-carbon-impact-left/

While I’m no longer in a position to make use of this, hopefully others are! I’m going to claim this for my #EnvironmentThisWeek even if I did make the initial feature request a few years ago 😅 — making feature suggestions for the environment does work.

InfraCarbon: Carbon Impact Visibility in Pull Requests

InfraCarbon shows the carbon impact of infrastructure changes directly in pull requests, alongside cost data, using trusted emissions data from Greenpixie.

This week I fixed holes and rips in several items of clothing. Maybe took an hour in total but has hopefully added a few more years to them.

#EnvironmentThisWeek

This week I did the same: fixed some rips in some running shoes using a speedy-stitch awl. Satisfyingly chonky thread.

#EnvironmentThisWeek

This week I fixed some holes in some socks, repatriated some lost property from a caving weekend, and sorted out 5kg of mixed rubbish and recycling from it too.

#EnvironmentThisWeek

This week I arranged installing a smart meter, which should show half hourly electricity consumption and hence help people reduce it. Arranging the installation was relatively straightforward

#EnvironmentThisWeek

This week I car shared to a fell race again. Not an exciting #EnvironmentThisWeek but still fewer cars on the road and less energy spent on moving them.

And we had a good natter on the way.

#EnvironmentThisWeek

This week I checked on some of the tree whips I planted earlier this season. Some of them had grown leaves briefly! Encouraging.

#EnvironmentThisWeek

This week I did bought two second hand kettles for a place I help maintain, to replace broken ones, rather than getting new ones.

The broken ones couldn’t be fixed (kettles are definitely not built to be repaired), but there are thankfully plenty of second hand ones in great condition.

#EnvironmentThisWeek

Last week (quite late with this one) I wrote to the FCC about proposed light pollution satellites: https://mastodon.social/@pwithnall/116065919158849340

#EnvironmentThisWeek

This week I finished upgrading the windows on my house to be triple glazed, for better insulation (and airtightness). I had quite a bit of help from friends. Worth it.

#EnvironmentThisWeek

This week (last week) I sorted out a bootful of building work waste from the previous week, for recycling. None of it went to landfill in the end, and maybe 5% of it had to go to waste-for-energy.

#EnvironmentThisWeek

This week I did more car sharing to various events, and advised some friends on insulation/airtightness improvements to their house.

#EnvironmentThisWeek

This (last) week I made some enquiries with my council about dark skies in planning policy.

#EnvironmentThisWeek

This week I did some more car sharing and blocked up some draughts in a building I help maintain, to reduce its heating bills.

#EnvironmentThisWeek

This week I redistributed some left over building materials from a few projects, to avoid them going to waste.

#EnvironmentThisWeek

@pwithnall pics or it didn’t happen.
(Actually curious to see a usable repair on running shoes. Haven’t been particularly lucky when I tried that in the past.)
@afranke Here we go (posed with the speedy-stitch). The thread is 3-filament waxed polyester. It’s particularly important to use a thread which won’t rot (cotton will rot). The wax makes it easier to work with and gives some extra protection to the thread once the repair is complete. The knot for each repair is on the inside to try and protect it (but don’t make the knot too big or it’ll irritate your foot).
@afranke For repairs on other clothing (typically caving gear) with this technique and thread, I have sometimes coated the repaired area in SeamGrip+WP glue after stitching to add extra protection against abrasion.
@pwithnall
I see. Sadly the main ways my shoes break is either when the outsole comes off (and haven’t had much success glueing it back), or the fabric at the back of the shoe where the ankle meets the shoe tears off and reveals the hard part underneath. Sometimes holes at the toe, then sewing might work.

@pwithnall I wonder whether (un)productive really is the term you ought to use for what you meant here, when productivity (and capitalism) is the reason you’re trying to do what you're trying to do in the first place. I get what you mean by unproductive, but it somehow feels inappropriate.
