I live rurally so a car is essential but we only have one and use cycles for local journeys.
I also wfh so have reduced commute. My DH cycles to local station for his commute to work.
I switch off shower between shampoo applications to reduce water use, and have water butts in the garden for my plants. Also have solar water tubes.
I keep bees and salvage beeswax to make candles after honey extraction.
I grow my own fruit and veg and shop locally when my garden isn’t producing anything and for meat, cheese, eggs and milk. 3-4 meat free days per week. Compost all peelings etc. Eat all the food made or bought, even if that means not eating something we fancy. Bulk cooking to reduce energy usage. Bake own bread and cakes.
Dry washing outside but I do iron as I hate creased clothes. I also sew and knit and if something can’t be mended, the fabric gets used for something else. Men’s shirts produce great baby and toddler clothes and the buttons match.
I do have wood burner as power supply to house is dodgy and I have a health condition which means I can’t be cold. But I keep central heating turned to 18c - when it works. And the wood for the burner is from our land.
I don’t need sanpro any more but would have used reusable if I’d known about it when younger. I did use terry nappies with my DCs when they were little.
We try not to fly much but our jobs require it from time to time. Now my DD has moved back to UK, my personal flights will be kept to a minimum - perhaps one every two years to visit other relatives.
My hobby is playing in a brass band. So we use old music and never require amps to ensure our audiences hear us. 
Only things I won’t give up is my highlights and good shampoo. My preferred one doesn’t come in a shampoo bar.
