1. Ask the lodge owner if they have a written policy regarding the environment and local people. If it’s not written down ("yeah, yeah, we do all that stuff") then it probably means there are not taking it seriously.
2. Ask them to describe the single contribution to conservation or local people that they are most proud of.
3. Ask them how they measure their contribution to conservation and local communities.
4. Ask the lodge owner how many local people they employ, what percentage this is of the total, and whether any are in management positions.
5. Ask them what they have specifically done to help protect the environment and support conservation, and which local charities they work with.
6. Ask them what percentage of products and services are sourced from within 25km of the lodge.
7. Ask them how they treat waste water (coral and other wildlife is being destroyed by Caribbean hotels pumping effluent out to sea, for example) and how they heat their building (solar is better than firewood, which can contribute to deforestation).
8. Ask them what information and advice is provided to tourists on local cultures and customs.
9. Ask them if they employ guides from the local community. Local guides not only provide unmatched insights into local cultures but are also aware of areas/behavior that might cause offence among local people.
10. Ask them for ideas on how you might get involved with local people and conservation in a worthwhile and rewarding way for you and the destination.
