#CitizensInititives / #GovernmentPetitions force governments to respond to political issues.
Switching.social recommends using CIs instead of commercial petition sites such as change.org.
You can find a list of CIs here:

In some countries, gathering enough signatures on a CI automatically triggers a debate in parliament, which can potentially lead to changes in law. For example, same-sex marriage in Finland was legalised through a CI.
