Sweden has an opt out system, but still has very low participation: https://www.bbc.com/news/health-41199918

I don't know where BBC got that information, but it is very wrong. It's entirely opt-in.

You need to either:

1) Register your wishes with the National Board of Health and Welfare

2) Fill in a donor card and carry it in your wallet

3) Notify next of kin/will etc

Upon your death you need to be pronounced dead twice with at least 2 hours apart, sometimes after a brain scan.

The low participation is indeed true, but according to a 2010 poll, 83% Swedes were positive to organ donation, but very few register as such.

Edit: Actually the participation doesn't seem that low [1].

From my understanding (although second-hand), the law theoretically describes an opt-out system, but this is (due to legal uncertainty about the details?) not acted on by the healthcare system, which instead relies on explicit consent.

For "low participation", do you mean that the majoritiy of population actively opted out?

How is the decision to opt out made?
