Best-case scenario, how much are we locked into?

Set aside the politics. If by some miracle we turned off carbon emissions immediately, how would the climate respond?
Ice cores are a window into the past hundreds of thousands of years.

The current rise in atmospheric carbon dioxide levels is unprecedented in the past 800,000 years. As our video explains, ice cores track human changes to the atmosphere that are far beyond natural.
Australia is falling far behind other countries in improving car pollution. ,

Australia’s road emissions have plateaued – last year showed the smallest reduction on record.
When we look at the latest car models we want fast cars, all-terrain cars or cars to fit the whole family. What about an environmentally friendly car?

The Australian market is awash with highly polluting cars. But there are a couple of key resources to help you find the best vehicle that fits your needs.

Diesel engines have been demonised for their emissions but the technology has already cleaned up its act.

Engineers are hoping to iron out a century-old technology that could reduce shipping emissions.
An emissions cap could save Australians up to A$500 each year in fuel costs.

The Australian government is considering a cap on car emissions, and the savings in fuel and health costs mean there’s no reason to delay.
Australia’s universities are great at green innovation, but not so good at going low-carbon themselves.

University research has shown us how urgently we need to reduce greenhouse emissions. Yet only three Australian universities have followed through by committing unequivocally to cutting carbon.

The Law and Justice party are making a grab for the Polish capital, by making it massive, but ultimately residents may pay the price.
If carbon regulations restrict how much a company can pollute where it’s located, it could move operations (and jobs) to another country – with no reduction in emissions.

Two environmental policy experts offer a more politically palatable way to lower carbon emissions – based on consumption, not conventional regulation.
The rise of renewable energy is one reason the world is shifting away from coal.

Global emissions from fossil fuels have stalled. That puts us in the right place to keep warming below 2°C, but there’s plenty of work still to be done.
New coal power technology can’t meet Australia’s climate targets alone.

As Australia’s energy debate heats up, some politicians are calling for cleaner and more efficient coal power stations to reduce greenhouse gas emissions.
Can coal be part of Australia’s efforts to reduce greenhouse gas emissions?

The idea of clean coal has been around for 40 years, but remains a pipe dream.
Cancelled flights might be your worst nightmare, but imagine a world with no flights.

With little hope of finding alternatives to jet fuel, we need to seriously consider a world without flying.

Why is everyone talking about ‘emissions intensity’ schemes this week?
Different foods have different amounts of greenhouse gases embedded in their production.

The food we eat is responsible for almost a third of our global carbon footprint.

Extreme wet years are getting wetter and more common. This means Australia’s terrestrial ecosystems will play a larger role in the global carbon cycle.
Australia’s National Electricity Market brings power to millions of people.

Australia’s electricity and climate agendas aren’t on the same page.
Electric cars are one of the keys to long-term decarbonisation.
