Whether forged by geological processes or laboratory techniques, diamonds are diamonds. Their unique properties mean they have applications that are not bling-related as well.
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.
A too rapid transition to a low-carbon economy would threaten financial stability. A slow transition would run the risk of exceeding irreversible ecological thresholds.
The carbon tax is an unpopular and deeply unequal measure. And Sweden, given as an example in this field, needs to be examined more closely.
Canada has made strides, but we're still far from being a climate leader. Budgeting our emissions would help bring us to the front of the pack.
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.
Tropical deforestation can release a huge amount of carbon into the atmosphere, contributing to climate change.
Less-toxic hair dye would be a great invention. But discounting the risks that come with nanoparticles could undermine other efforts to protect human health and environmental from their effects.
Canada has committed to cutting GHG emissions 30 per cent by 2030 from 2005 levels. Can Canada's oil capital lead the charge? New research shows it's within reach with bold actions on several fronts.
The world is made of tiny building blocks called 'elements'. Scientists have worked out how fast some elements change into other elements. That gives us a very big clue about how old the Earth is.
A scheme in Wales to introduce personal carbon accounts could point the way to reduce emissions.
Consistent carbon pricing is a key element in the fight against climate change.
While China launches its new energy market, Australia is still lagging behind in implementing a mechanism to control carbon emissions
Boron is the hidden ingredient in a lot of our technology. Get to know this plucky little element.
Can forests effectively remove carbon from the atmosphere?
It's like one great big distillery up there.
Compressed glassy carbon could be used to make better bulletproof vests or new types of electronics.
Pollution has increased carbon in our soils - which is good for climate change. But this carbon may not stay there for long.
On June 1, Donald Trump announced that he would take the US out of the Paris climate agreement because it was "unfair" to the US. An economic analysis indicates otherwise.
Global warming and carbon emissions, left unchecked, could cause rising sea levels and displace almost 200 million people. But we can still prevent the worst case scenario if we act now.
