Yes and no. I feel that not doing certain things is a very simple thing to "do" things - and I appreciate simplicity.
For example, I would probably prefer getting rid of half of the cars and trying to find ways so that people do not need to move that much, if they do not want to (for example making all possibly remote remote work actually remote) - as opposed to making all cars electric.
I do not own a car, I do not fly, I buy clothes used or new just once a year. My newest smartphone I bought five years ago (and I just bought a new battery for $10, so I can use it for five more years). My utility company stats says my energy consumption is overall very low. I eat meat once a month. I try to own as few things as possible. I try to write and deploy code in energy efficient languages (Go, Rust, C, ...) [1]. I self host some services on my arm board that consumes 0.79W when idle.
I do not feel, that it makes a large dent, but I feel that I'm way ahead what the average person does in order to reduce their environmental footprint.
Also, I do not feel I'm cutting myself short and I still depend on many of the niceties of modern civilization - but, I'd also be happier, if my footprint would be even lower.
Just a thought: Is it mostly select statements that your colleagues write? Because if they do, they might not fear accidentally altering the data. I found that new programmers can get confused by the difference between things that are immutable and those that aren't.
