Who are the major players in the recent environmental movement?

There isn’t one leader or organization speaking for the whole environmental movement. It is a loose mix of local campaigns, youth groups, Indigenous leaders, scientists and established nonprofits. The people most visible in the news may change, and the key voices often depend on the issue and region.

Some prominent people and groups

• Greta Thunberg and Fridays for Future: Thunberg helped draw international attention to youth climate strikes. Fridays for Future is a decentralized student-led movement, with organizers around the world shaping their own campaigns.
• Vanessa Nakate: The Ugandan climate activist has raised the profile of African climate voices and the unequal effects of climate change.
• Indigenous leaders and organizations: Activists such as Nemonte Nenquimo and Hindou Oumarou Ibrahim, alongside groups like the Indigenous Environmental Network, connect environmental protection with Indigenous rights, land and community sovereignty.
• Climate justice groups: Organizations including 350.org, the Sunrise Movement and the Climate Action Network organize campaigns and build pressure for policy changes. Greenpeace and Friends of the Earth also have long-running environmental campaigns.
• Scientists and communicators: Researchers such as Katharine Hayhoe help explain climate evidence and its local consequences, while contributing to public discussion and policy debate.

These are examples, not a definitive ranking. The movement also includes thousands of community groups working on issues such as pollution, biodiversity, water access and fossil fuel expansion. In many places, Indigenous-led environmental campaigns and local organizers are central, even when they receive less international media attention.
