Proportional approval voting
Multiple-winner electoral system / From Wikipedia, the free encyclopedia
Proportional approval voting (PAV) is a proportional electoral system for multiwinner elections. It is a multiwinner approval method that extends the highest averages method of apportionment commonly used to calculate apportionments for party-list proportional representation.[1] However, PAV allows voters to support only the candidates they approve of, rather than being forced to approve or reject all candidates on a given party list.[2]

Not to be confused with sequential proportional approval voting, an approximation algorithm for proportional approval voting.
In PAV, voters cast approval ballots marking all candidates they approve of; each voter's ballot is then treated as if all candidates on the ballot were on their own "party list." Seats are then apportioned between candidates in a way that ensures all coalitions are represented proportionally.
