Well done so far.
Electric car doesn’t have to cost a fortune- if you’re not too fussed with range then second hand they start at 5-7k. Worth looking at getting one longer term- they eventually pay for themselves when you consider you never have to pay for petrol! We love ours and it costs pennies to run.
In the meantime try and reduce car journeys depending on where you live. Consider walking/cycling or public transport if further. If you are a two car family could you cope with one? I was sceptical but we’ve coped ok with one for 10 years now.
We have solar panels on the roof-
Not for electricity but they are connected to the gas and heat our hot water april- October and sunny days in between. Cost a few k but again they have now paid for themselves through a lower gas bill. If you are staying put for a few years def worth looking into.
Like you I can’t do vegan but quite easy to eat meat free most days a week. Beef is by far the most un-environmentally friendly meat so try and reduce that as much as you can.
I’m not sure about the who gives a crap
Toilet paper but we use regular Sainsbury’s recycled which is cheap and fine.
I’m not ready to give up flying but haven’t for two years and actively consider alternatives. In my opinion flying once a year on a family holiday is ok (dh disagrees) but doing lots of flights per year to exotic places is irresponsible. Train travel to the continent is fab.
Eco egg and water butts are good ideas. Eco egg so easy and cheap. However I’m not sure it would handle nappies. But you could use it for general laundry fine. I also use ecover stuff but I don’t think it is as friendly as all that- owned by SC johnson which are ethically dubious. Independent eco-shops have better alternatives -ours has a massive refillable thing which we visit once a month or so- but I freely admit that you want to be able to source stuff easily. Worth seeing if there is a zero-waste/eco shop locally where you can buy stuff in bulk and massively reduce packaging waste. This will come to supermarkets eventually.
But the biggie is probably making sure your house as well insulated as it can be. A shockingly high percentage of energy is wasted because people don’t insulate homes properly.
And also just talking to other families about what you are doing and why.
