Final Version of Global Critical Minerals Treaty Stripped of Traceability Measures (Mongabay)

At the seventh U.N. Environment Assembly in December 2025, Colombia and Oman jointly proposed a legally binding international treaty to create traceability and due diligence mechanisms across global mineral supply chains. Their proposal faced resistance from multiple countries including Saudi Arabia, Russia, Iran, Chile, and Uganda, and ultimately resulted in a watered-down nonbinding resolution on mineral governance that excluded traceability provisions entirely.

Multilateralism is under threat, as many global powers increasingly choose to center their security priorities around defense and economic competition over international cooperation. This shift toward short-term national interests risks undermining progress on joint challenges, including climate change, peace and justice. What will be lost if the climate security agenda becomes a battlefield of competing interests? How can peacebuilding and development actors respond?

Indonesia produces more than half of the world’s nickel output – a critical component in batteries for four- and two-wheel electric vehicles (EVs). Mostly Chinese-owned smelters work around the clock in Sulawesi to process the nickel ore and ship it across the globe. Indonesia’s resource nationalism – the government policy banning ore exports and forcing domestic processing appears to have worked well – but only in the upstream segment of the supply chains.

Community Forests Are the Frontline of a Minerals Race in the DRC (Mongabay) 

In the Democratic Republic of Congo’s copper-cobalt belt, local communities are establishing community forest concessions to secure land titles and prevent eviction by mining companies. Sparked by previous displacement incidents, these concessions allow communities to hold up to 50,000 hectares in perpetuity. This region holds approximately 70% of the world’s cobalt reserves, which has attracted intense competition from Chinese companies, the United States, and the DRC state-owned Gécamines to obtain minerals essential to high-tech, weapons, and clean energy industries. Between 2001 and 2024, 1.38 million hectares of tree cover in Lualaba and Haut-Katanga provinces were lost due to mining activities.

Race for Copper Damages Protected Region in Colombia (Mongabay)

As Colombia looks to meet the growing demand for strategic minerals, activists working in the department of Choco allege that the country’s only industrial copper mine is harming both the environment and a local community. The El Roble copper mine has operated since 1990 at the base of a valley crossed by the Atrato River, but its acquisition by Canadian multinational Atico Mining in 2013 has meant that daily production has doubled from 400 to 1,000 metric tons over the past 12 years. El Roble also lacks the environmental license required by Colombia’s Mining Code, and continues to operate under a less stringent 1987 environmental management plan, which activists say omits required environmental impact studies.

Deforestation and Flooding Turns Fallen Timber into Projectiles in Indonesia (The New York Times) 

When Cyclone Senyar struck in late November, its death toll numbered 800 people across Indonesia, Malaysia, and Thailand. The Indonesian island of Sumatra saw a particular sort of damage as the storm unleashed sixteen inches of rain in parts of the island, wiped out four villages, and triggered flash floods and landslides. Decades of razing and converting natural forests into palm oil plantations, pulpwood farms, and gold mines drastically increased the region’s vulnerability to floods and landslides to the point that timber was transformed into projectiles that destroyed residences and infrastructure.

Nickel Mining Threat to New Raja Ampat UNESCO Biosphere Reserve (Mongabay) 

When Indonesia’s Raja Ampat archipelago received a UNESCO Biosphere Reserve designation on September 27, 2025, the new designation adding to the status it won as a Global Geopark in 2023. Yet this dual honor highlighting the archipelago’s exceptional biodiversity is now under threat from intense pressure from global demand for nickel for electric vehicle batteries that is challenging the reserve’s conservation goals.

Mexico’s Mercury Boom is Poisoning People and the Environment (Associated Press)

In Mexico’s Sierra Gorda mountains, soaring international gold prices also have created a mercury boom. Since 2011, mercury prices have skyrocketed from $20 per kilogram to between $240 and $350 per kilogram today. Most of Mexico’s mercury is trafficked to Colombia, Bolivia, and Peru for use in illegal Amazon gold mining operations that contaminate rivers and ecosystems. Yet the country’s adoption of a 2017 UN convention banning mercury mining and exports also allows artisanal mines to operate until 2032.
