Theonila Roka Matbob
Theonila Roka Matbob led a successful campaign that compelled Rio Tinto, the world’s second-largest mining company, to sign a landmark memorandum of understanding in November 2024 to address environmental and social devastation caused by its long-dormant Panguna mine. Despite having abandoned the site 35 years earlier after a social uprising against the mine, the company formally acknowledged the wide range of harms the mine has caused and has begun a collaborative remediation process that aims to address urgent risks and establish a long-term remedy mechanism.
Carlos Mallo Molina
Carlos Mallo Molina helped lead a sophisticated, global campaign to prevent the construction of Fonsalía Port, a massive recreational boat and ferry terminal that threatened a biodiverse 170,000-acre marine protected area in the Canary Islands. Proposed to be built on the island of Tenerife, the port would have destroyed vital habitat for endangered sea turtles, whales, and sharks. In October 2021, because of the campaign, the Canary Islands government officially canceled the port project. In lieu of the port, Carlos is now realizing his vision for a world-class marine conservation and education center—the first of its kind in the Canary Islands.
Murrawah Maroochy Johnson
Murrawah Maroochy Johnson blocked development of the Waratah coal mine, which would have accelerated climate change in Queensland, destroyed the nearly 20,000-acre Bimblebox Nature Refuge, added 1.58 billion tons of CO2 to the atmosphere over its lifetime, and threatened Indigenous rights and culture. Murrawah’s case, which overcame a 2023 appeal, set a precedent that enables other First Nations people to challenge coal projects by linking climate change to human and Indigenous rights.
Delima Silalahi
Delima Silalahi led a campaign to secure legal stewardship of 17,824 acres of tropical forest land for six Indigenous communities in North Sumatra. Her community’s activism reclaimed this territory from a pulp and paper company that had partially converted it into a monoculture, non-native, industrial eucalyptus plantation. The six communities have begun restoring the forests, creating valuable carbon sinks of biodiverse Indonesian tropical forest.
Julien Vincent
Julien Vincent led a successful grassroots campaign to defund coal in Australia, a major coal exporter, culminating in commitments from the nation’s four largest banks to end funding for coal projects by 2030. Because of Julien’s activism, Australia’s major insurance companies have also agreed to cease underwriting new coal projects. His organizing has produced a challenging financial landscape for the Australian coal industry, a significant step toward reducing fossil fuels that hasten climate change.
Kimiko Hirata
After the Fukushima Daiichi nuclear disaster of 2011, Japan was forced to move away from nuclear power and, in its place, embraced coal as a major energy source. Over the past several years, Kimiko Hirata’s grassroots campaign led to the cancellation of 13 coal power plants (7GW or 7,030MW) in Japan. These coal plants would have released more than 1.6 billion tons of CO2 over their lifetimes. The carbon impact of Hirata’s activism is the equivalent of taking 7.5 million passenger cars off the road every year for 40 years.
