One big problem with plastics is that they’re largely made of petroleum. Sourcing bio-polymers from plants and bacteria has some big benefits – and the technology is starting to take off.

The idea of a renewable energy transition is exciting. It opens up space to think about enhancing democracy and decolonization.
Woody plants’ cover has increased across large swathes of the continent in the past three decades.
Urban trees are literally made with the help of human breath – they turn the carbon dioxide we breathe out into the building blocks of plant growth. So your local trees have a piece of you inside them.
Technology exists to capture carbon dioxide from the atmosphere but it has a big cost.
New research has suggested a fresh way to account for greenhouse gases with different lifetimes in the atmosphere.
In an increasingly urban world, trees can make a major difference. One study found that, for every dollar invested in planting, megacities saw a $2.50 return on their investment.
New research finds more CO₂ can actually make most plants smaller in the long-term - but the story for crops isn’t so simple.
Until now, the international shipping industry has been excluded from the Paris Agreement and the Kyoto Protocol, despite its major contribution to global emissions.
AGL has announced plans to use coal to make hydrogen fuel at its Loy Yang A station in Victoria’s Latrobe Valley. Wait, isn’t coal made of carbon, not hydrogen? Yes, but here’s how the process works.
In the future, traps for mosquito that spread the dengue and chikungunya virus could be made from the carbon dioxide in human breathe as well as body odour.
Ocean acidification poses an increasing threat to the sediments that form the framework of coral reefs - within around 30 years, these carbonate sands may no longer be able to form.
It may be just as well the UK government scrapped its previous carbon capture competition.
Consistent carbon pricing is a key element in the fight against climate change.
It’s not all bad news at Bonn – with low carbon precincts, living infrastructure and urban networks, cities are leading the charge against climate change.
As delegates meet in Bonn for the latest rounds of climate talks, civil society, NGOs, cities, regional governments and businesses, are stepping up to work together toward climate goals.
The CO2 we produce when we put up buildings is large and virtually unregulated.
Canada ratified the Paris agreement on climate change, but it hasn’t yet filled the leadership void left by the United States. Time is running out.
Global greenhouse gas levels have hit their highest point in at least 3 million years, according to new figures from the World Meteorological Organisation.
New data from a NASA satellite show in unprecedented detail the flow of carbon dioxide into the atmosphere. Future satellites should even be able to detect the signatures of individual power stations.
