Carbon Dioxide

Concrete is the most widely used building material in the world, but it comes at a huge environmental cost. Engineers in Japan have developed a new technique to make concrete by recycling waste concrete and combining it with captured carbon dioxide.

A company at the cutting edge of carbon capture technology has outlined its vision to use Australia's vast, open spaces and abundant sunlight to power millions of modular systems that would collect millions of tons of CO2 each year.

Carbon dioxide in the atmosphere attracts most of the attention in environmental concerns, but much of that ends up in oceans, making them more acidic. Now scientists have created nanojars that can easily capture this and other pollutants from water.

Climate change can feel inevitable, but we’ve stepped up to the challenge before. New modeling shows how bad things would be if CFCs hadn’t been banned decades ago – depleted ozone would've increased UV exposure and stopped plants capturing carbon.

According to a new report issued by the United Nations' Intergovernmental Panel on Climate Change (IPCC), human-caused climate change will have dire consequences over the next 20 years.

Carbon dioxide may finally get its chance to become a solution in the climate crisis. Italy's Energy Dome says its CO2 batteries will store energy at less than half the cost of lithium "big batteries," while also being very responsive to load demand.

Something is making methane on Saturn’s moon Enceladus. A new study has found that methane levels detected from the icy moon are far higher than can be explained by known geochemical processes – but they are consistent with microbes.

Researchers have created a new alloy made up of not two, but five different metals, and put it to work as a catalyst. The 2D material was able to convert carbon dioxide into carbon monoxide, potentially helping to turn the greenhouse gas into fuels.

In many countries, long, dark winters limit the amount of solar energy that can be generated for much of the year. That's where the Underground Sun Conversion system comes in, as it's intended to use sunlight to help produce natural gas underground.

We have seen some interesting developments around what's known as self-healing concrete that repairs its own cracks, and scientists have now demonstrated an exciting new form of this that makes use of an enzyme found in human blood.

Scientists measuring concentrations of CO2 in the atmosphere at the Mauna Loa Atmospheric Baseline Observatory have reported the highest levels on record, and ones not see on Earth in more than four million years.

Have you ever wondered how many bubbles there are in your Friday knockoff beer? No? Well scientists apparently have, and in a new study they’ve finally answered the question nobody’s been asking, with a vague “a lot, we guess.”
