Individually, reducing the carbon emissions you are directly responsible for (either by using greener tech or just reducing consumption) and planting some trees is basically the best you can do directly. This kind of tech, if it does become a good solution, will be a large industrial process, not something it makes sense to operate individually. And of course the best thing to do is continue to advocate for action politically, even though it may be hard to count exactly how much of a difference you are making there.
