"Pope Francis called them to "the grave ethical and moral responsibility to act without delay, in a manner as free as possible from political and economic pressures" in their efforts to combat climate change."

That is very good, and if followed would have cause some praise and criticism by almost everyone on all sides of the issues.  The phrase "free as possible from political and economic pressures" goes both ways. They should not be dictated and pressured by political and short term economic pressures, but they should not apply political and economic pressures to others.

I think a way forward is to:
- Identify practical conservation measures and energy saving products and methods
- Keep tabs on both technological developments in renewable energy processes and also high tech advances in low energy nuclear reaction developments, making these developments commonly known and advocating their adoption.
