Researchers from the Institute of Advanced Sustainability Studies and Karlsruhe Institute of Technology have developed a process that extracts the energy content of methane, in the form hydrogen, without producing carbon dioxide.

NASA has analyzed 14 years worth of data collected by its TIMED satellite, revealing a surprisingly fast increase in carbon dioxide levels in the upper atmosphere. The stats also reveal that the gas is more localized to the Northern Hemisphere than predicted by climate models.

A new study has revealed that during the period in which the red planet's distinctive valleys supposedly formed, the Martian atmosphere may have already been too depleted to maintain the free-running water that it is believed to have carved out the geological features.

Scientists have created a hybrid system of bacteria and semiconducting nanowires that take water, sunlight and carbon dioxide and turn them into the building blocks of biodegradable plastics, pharmaceutical drugs and even biofuel.

In order to minimize the amount of greenhouse gases entering the atmosphere, scientists have studied materials that could be used to capture excess CO2. Unfortunately, not all of them are cheap or easy to produce. That said, researchers now believe that humble clay could do the job just fine.

Many technologies developed for capturing carbon dioxide emissions have a limitation – in order to reclaim the captured CO2, a considerable amount of energy is needed. Now, however, scientists have developed a new carbon-capture material that requires far less energy in order to give up its payload.

An engine powered by frozen carbon dioxide holds the potential to use the natural resources found on Mars to supply the on-going energy requirements of future long-term missions or attempts at colonization of the planet.

Carbon sequestration may not, according to researchers at MIT, be the panacea that some had hoped. A recent study has found that far less carbon dioxide than the ideal prediction of 90 percent may be turned into rock when sequestered.

As one of our most relied upon construction materials, concrete makes a significant contribution to our overall carbon emissions. By altering the quantities of materials used in this process, scientists have uncovered a method of cement mixing that could reduce these emissions by more than half.
