Hydrogen fuel cells are a promising renewable energy technology that converts hydrogen into electricity through a chemical reaction with oxygen, producing only water as a byproduct. They offer high efficiency and zero emissions, making them ideal for applications in transportation, stationary power generation, and energy storage. By utilizing renewable sources to produce hydrogen, fuel cells can play a pivotal role in reducing dependence on fossil fuels and combating climate change.

Plastic waste is a growing crisis in Indonesia, with 3.2 million tons produced annually, and up to 1.29 million tons ending up in the ocean. The linear economy accelerates this issue by encouraging use and discard practices. A circular economy promotes reuse, recycling, and sustainability, offering a viable solution. By integrating innovation and community efforts, Indonesia can reduce waste, conserve resources, and drive sustainable change. Let's get to know some local innovations in pursuing this circular economy!

Often overlooked, kitchen waste significantly contributes to the climate crisis. As organic waste decomposes, it releases methane (CH₄)—a potent greenhouse gas. Indonesia generates 92,600 tons of waste daily, with 39.2% being organic, much of which ends up in landfills, increasing emissions. Sustainable waste management—through composting, eco-enzymes, and circular economy solutions—can help reduce environmental impact. Let’s turn waste into value for a greener future!

The global ecological and climate crisis continues to worsen coastal environmental damage, such as shoreline abrasion threatening areas like Derawan Island. Uncontrolled exploitation of natural resources and unsustainable infrastructure development have disrupted ecological balance. Structural mitigation, such as seawalls, presents ecological and economic limitations. As a more sustainable solution, Nature-Based Solutions (NbS), like mangrove restoration, offer ecological and social benefits. Successful restoration depends on cross-sector collaboration and active involvement of local communities as part of a multifunctional adaptive strategy.

Indonesia is home to six of the world’s seven sea turtle species nesting regularly along the southern coast of Yogyakarta. Each species holds a different conservation status, ranging from Vulnerable to Critically Endangered, underscoring the urgency of protection efforts. Conservation patrols, egg relocation, and habitat monitoring led by local communities and organizations are vital to increase hatching success and safeguard these ancient species. With their crucial ecological roles—from maintaining seagrass beds to controlling jellyfish populations—every hatchling that survives contributes to the resilience of Indonesia’s marine ecosystems and supports sustainable coastal livelihoods.

Coral reefs are vital marine ecosystems that support high biodiversity and provide essential benefits for coastal communities, yet they are increasingly threatened by climate change and destructive human activities such as indiscriminate anchoring that damages reef structures and disrupts fisheries, tourism, and food security. An effective solution to prevent this damage is the use of mooring buoys, environmentally friendly fixed anchoring points that have proven successful in protecting reefs in busy marine tourism areas for ocean conservation and sustainable coastal economies.

Often misunderstood, climate ambition is not a barrier to development—it’s a strategic asset for Indonesia’s future. This year’s NZS 2025 carries the theme: “Raising Indonesia's Game: Staying Climate-Focused in Times of Great Distraction”, emphasizing that bold climate action is key to achieving the Indonesia Emas 2045 vision. Staying committed to Net Zero means investing in resilience, innovation, and long-term prosperity. Let’s keep climate at the center of our national journey.

The energy transition through electric vehicles is often seen as a solution to the climate crisis, yet it still relies on fossil fuels in production, energy supply, and underlying economic systems. At the same time, the rise of green consumerism has encouraged greenwashing, such as “zero emission” claims that ignore the full product life cycle. This creates incomplete public perceptions and risks reducing the transition to mere branding. Therefore, transparency and comprehensive evaluation are essential to ensure electric vehicles truly contribute to climate change mitigation.

Agriculture plays a paradoxical role in the climate crisis, contributing 21–37% of global greenhouse gas emissions while remaining highly vulnerable to its impacts. In Indonesia, where over 90% of farms are managed by smallholders with limited resources, climate events such as the 2023 El Niño have exposed the fragility of the food system. This article highlights FAO SDG Indicator 2.4.1 as a key framework for sustainable agriculture, emphasizing that farmer welfare is essential to achieving long-term sustainability.

Biodiversity is increasingly recognized as a critical foundation for both environmental sustainability and long-term business resilience. As biodiversity loss accelerates due to resource exploitation, land-use change, pollution, and climate change, companies face growing risks to supply chains, operations, and economic performance. In response, many businesses are adopting Corporate Biodiversity Strategies that integrate biodiversity considerations into decision-making, risk management, and sustainability initiatives.
