Australia's States Are Racing to Go Green—But Not Together

Australia is trying to shift away from fossil fuels and move toward renewable energy. The catch: each state is doing it on its own timeline and in its own way. A new report from the OECD, an international organization that studies economic policy, found that different states have made wildly different promises about when they'll reach "net zero"—the point where they stop adding greenhouse gases to the atmosphere. Some are years ahead of others, and they're using completely different strategies to get there.

This patchwork of approaches reveals a bigger problem: the federal government hasn't stepped in to coordinate these efforts or set clear national standards. Instead, states are filling the gaps themselves, which works in some places but creates confusion elsewhere.

Some States Are Winning, Others Are Just Starting

Tasmania has already made remarkable progress. The island state has run entirely on renewable electricity since 2020, powered mostly by hydroelectric dams built decades ago. That puts it far ahead of the pack.

The Australian Capital Territory has been even more ambitious, committing to net zero by 2045—earlier than most other states. New South Wales, the most populous state, is aiming for 2050 but has promised to cut emissions in half by 2030 compared to 2005 levels. Western Australia is taking a different tack: it plans to shut down all its coal-fired power plants by 2030, one of the fastest coal phase-outs anywhere in the world.

These differences aren't random. Tasmania could move quickly because it already had hydroelectric infrastructure in place. Western Australia is retiring coal partly because its aging coal plants are becoming too expensive to maintain anyway. New South Wales faces a tougher puzzle—it has to replace coal while keeping the lights on for Australia's biggest city.

The Federal Government Fell Behind

Here's where things get messy. The Australian government announced its electric vehicle strategy in May 2023, but states had already started their own EV programs two years earlier. The federal government's rules on vehicle emissions came out even later, in August 2022, suggesting they were catching up to what states were already doing rather than leading the way.

This lag matters because electric vehicles need more of certain rare materials—lithium, cobalt, and others—than gas-powered cars do. So do solar panels and wind turbines. Australia has lots of these materials in the ground, but without a coordinated national plan, the country isn't taking full advantage. There's no joined-up strategy connecting mining these materials to actually making batteries and renewable equipment here at home.

The broader context here is that state-by-state action can drive innovation and move things faster in some cases. But it also risks creating a fragmented market where different states have different rules, making life harder for businesses and consumers who operate across borders.

The Problem With Going It Alone

The critical minerals issue points to something bigger: some challenges simply cannot be solved by one state acting alone. China currently dominates the processing of rare earth minerals and battery materials worldwide, which means Australia's renewable energy plans depend on supply chains the country doesn't control. Western Australia's plan to shut down coal plants by 2030 relies on battery storage technology that comes mostly from Asia.

Tasmania's renewable electricity success offers another cautionary tale. The state achieves 100% renewables partly because it can send power through underwater cables to mainland Australia's electricity grid during times of shortage. This kind of infrastructure links different states together—you can't plan it state by state.

This situation echoes something that happened in Australia in the 1990s with telecommunications. States initially pursued their own digital infrastructure strategies, which sped things up in some places but created inefficiencies in others. Eventually, Australia realized it needed a national framework. Climate policy is heading down the same path right now.

Missing Pieces That Only the Federal Government Can Fix

Electric vehicle charging stations illustrate the problem clearly. If each state builds its own charging network with its own payment systems, someone driving across state borders might find incompatible chargers or dead zones where no chargers exist. Australia is huge compared to European countries, with long distances between cities, so these gaps matter more here than elsewhere.

As more states add wind and solar power, the electricity grid itself faces new challenges. South Australia experienced state-wide blackouts during extreme weather in 2016, which showed what can go wrong when a state adds too much renewable power without enough backup storage or transmission lines to handle it. As other states retire coal and add renewables, these grid stability questions will only get bigger—and they need answers at the national level, not just the state level.

The minerals issue also demands federal involvement. Trade deals, mining approvals, and decisions about building battery factories need to happen at the national level. States can't negotiate those on their own.

What Happens Next Matters

Australia's federal system—where power is split between national and state governments—does have an advantage: states can test new ideas and show what works. Tasmania's renewable success and Western Australia's rapid coal phase-out prove states can act boldly on climate.

But the current gaps between state ambitions and federal coordination pose a real risk. The question facing Australia right now is whether the different state efforts will eventually line up around shared national standards, or whether the country will end up with a patchwork that slows the whole transition down. The next few years, as 2030 targets get closer, will show whether Australia can pull this together or whether states end up working at cross-purposes.
