There's so much in here, and it honestly doesn't really matter to me. The only question I really care about: what are you willing to give up if you believe golf has an impact on climate change?
Apologies for putting so much in there that doesn't matter LOL. You've been bouncing back and forth between asking people specifics about what they've done or would be willing to do, and making big statements about the scientific community.
If you want to swing the pendulum back to the former, I'm not at all sure that golf has that much of an impact on climate change, but certainly as a game that takes up a lot of land there is a responsibility to be a good steward. Water usage especially in arid areas should be a concern. I'm probably not a great example for what to give up as it relates to golf, because I barely play golf anymore.
The travel (as Alex mentioned) is something that all of us could be more mindful of - travelling for golf is probably more of a concern than actually playing the game. It's easy for us all to say we've traveled less over the past couple of years thanks to COVID, but I haven't flown in over two years and I plan to do less of it both for work and personal travel. But given the amount of fuel used by a typical commercial flight, and that an estimated 80-85% of the world's population has never taken even one flight, flying around the globe simply to hit a ball around a field is a energy-consuming luxury that we could cut back on.
As far as other actions, I installed solar panels on my home five years ago. Yes I know it takes resources to build solar panels. They provide about 93% of the power for my home. Next steps would be a solar water heater and setting up a rainwater harvester, I'm looking into those.
I've been a vegetarian for 12 years. The carbon footprint for meat production compared to grain is eye-opening. There are other reasons I became vegetarian but lowering my carbon footprint is one of them, especially because we try to eat local and in-season as much as possible.
I work from home entirely, no commuting anymore. Not sure that avoiding sitting in traffic really counts as a sacrifice! I do have three kids, which is probably not the best thing for using fewer resources, but we bike them to school about 60% of the time.
Reducing consumption of single-use plastics, composting, adjusting the thermostat seasonally, etc. all make a difference. Pretty much everyone on this board is big time first world so it's really hard to not consume more than our share but it's also not that hard to reduce your footprint.
