Personal choice is only about 5% of the change needed to mitigate climate change. Individuals can not choose most things, such as steel and cement and plastic production, they can't enact a carbon tax, they can't close down coal plants or raise capital for nuclear or renewables. Can individuals educate millions of women in the third world or change how refrigerants are managed? Look at drawdown.org, you will see the majority of reductions will be on elected officials and corporations.
The most developed world individuals can do, as you say, is reduce their own footprint in minimal ways and VOTE!!
