The XPrize foundation has today launched a new US$10 million competition geared towards preserving the world's rainforests, a process that begins with building new technologies to help us better appreciate what they have to offer.

Greenhouse gases like methane and nitrous oxide can be worse than carbon dioxide. Now, a new study has found that we’re releasing more N2O into the atmosphere than we thought, which may weaken our already-strained efforts to combat climate change.

A growing cohort of small companies are working to offer products that make eating when we’re out and about a less wasteful affair, the latest of which offers a durable set of cutlery that snaps together for easy carry.

Scientists have uncovered an unfortunate feedback loop that could make things worse for the climate. According to a new study, ocean acidification seems to increase the amount of nitrous oxide, a potent greenhouse gas, that’s released into the air.

In what is being hailed as a historic moment for the island nation of five million people, New Zealand’s parliament has passed new legislation that commits the country to a carbon neutral economy by 2050.

A new report declaring a climate emergency has been signed by thousands of scientists. But it remains hopeful, outlining six steps we can take to mitigate the worst effects of climate change – provided we act sooner rather than later.

Disassembling electronics into their various components for recycling is a laborious process, and involves the use of eco-unfriendly solvents. Now, however, scientists have developed a magnetically-deactivated glue that could address these problems.

The burning of agricultural waste and the methane that's burped up by cows are two major sources of greenhouse gases. An experimental new type of animal feed, however, is aimed at reducing both the burning and the burps.

Concrete is made of a combination of cement, an aggregate such as gravel, and water. If that mixture dries too fast, then cracks can form within it as it cures. Now, however, scientists have determined that the use of coal-ash spheres can help keep that from happening.

Researchers at MIT have developed a new method for pulling carbon dioxide out of a chimney flue at a power plant or even just ambient air. The new device is a specialized battery that absorbs CO2 while charging, then releases it for industrial use.

With its huge barriers now successfully collecting trash from the Great Pacific Garbage Patch, the Ocean Cleanup Project is heading upstream to tackle the issue closer to the source with "The Interceptor," a system to pull waste from rivers.

In the chemical-production industry, energy-intensive processes are constantly being used to remove unwanted molecules from liquids. It now looks like much of that energy could be saved, however, by utilizing filters made from plastic bottles.
