We need to apply system level thinking to this problem, what is a strategy that will lead to zero (acceptable) emissions? We need to focus 100% on that strategy. I believe lifestyle changes based on moral arguments are a distraction due to the following reasons:
1. Its completely unrealistic to change behaviour at that scale
2. Even if successful the effect is only a minor delay, not an actual solution. Any gains due to consumption reductions is more than offset by growth.
3. Focusing on such things may be counterproductive. First by creating opposition to the entire climate change agenda, telling people to change their way of life makes them oppose it any way they can, including denying the problem completely. Secondly we need to stimulate demand for zero emission technologies, reducing consumption is counterproductive to that.
