Methane, the Silent Killer

Why is methane a big deal?

Methane is a powerful greenhouse gas—86 times more potent than carbon dioxide over a 20-year period. It’s responsible for a third of global warming to date and is accelerating the climate crisis, pushing us toward dangerous temperature increases. Methane emissions are driving extreme weather events, threatening our lives, livelihoods, communities, and Queensland’s iconic natural wonders.

But there’s hope. Methane’s short-term potency means we have an opportunity to act quickly. If we cut methane emissions today, we could prevent nearly 0.3°C of global warming by 2045—making a tangible impact in our lifetime. Reducing methane is one of the fastest, most effective ways to fight climate change and help keep global temperatures within the 1.5°C limit we urgently need to stay safe.

Why does methane matter in Queensland?

When people think of methane, they often imagine cow burps or agricultural sources. But in Queensland, the real threat comes from coal and gas mining. These industries are some of the state’s largest and fastest-growing sources of methane emissions, predicted to become the biggest contributors by the end of the decade.

Methane isn’t just fueling climate disasters like floods and heatwaves—it’s also worsening air quality and putting our health at risk. Communities near the Bowen Basin and beyond are facing more respiratory issues, while farmers are struggling as methane-driven climate changes make it harder to grow crops and raise livestock. Meanwhile, corporations are profiting while everyday Queenslanders bear the brunt of the fallout.

What can be done about it?

The fastest way to cut methane in Queensland is to stop new coal and gas projects. But we must also tackle the methane leaks from existing mines. Proven technologies, such as methane capture and reduction systems, are already in use worldwide—and they could make a real difference here.

Right now, Queensland’s coal mines are releasing vast amounts of methane with little oversight. Weak regulations and poor monitoring allow corporations to avoid accountability. We need better tracking and stricter regulations to hold polluters responsible and curb their emissions.
