It sounds like you are well-informed on this issue. I'd like to ask you more about it but I can't seem to find any kind of private messaging functionality on HN and you don't have an email address in your profile :O
I'm wondering who the key players are, what is currently being done, whether there's opportunity for public pressure to influence any of the actors, etc.
I'm sure they have a much better assessment than I could ever make of the worst performers, the biggest players, and the key organizations to target to bring change. Not to mention that if they have campaigns running/planned it would be nice to coordinate with what it sounds like your organization is doing. Annisa Rahmawati (@AnisaHijauDamai) was representing them at this years RSPO european roundtable two weeks ago.
The WWF is also very involved with the RSPO and Palm Oil. Good luck!
