VOICED: An EU vote is a green vote, campaigners say

The Green Party advocates for the Lisbon Treaty, emphasizing its role in combating climate change. They highlight Europe's leadership in global climate efforts and stress the importance of a unified European Union to strengthen negotiating power. Despite these arguments, some voters in Dublin are not primarily motivated by environmental concerns. The Green Party hopes that those who care about the environment will support the Treaty, but the outcome remains uncertain until after the vote.
