Carbon Neutral

This strange white paste might not look like much, but it could not only solve the sand shortage, but make the cement manufacturing process absorb carbon dioxide instead of emitting it. Scientists grew this stuff out of seawater, electricity and CO2.

Researchers at UCLA have successfully devised a way to produce cement with 98% less CO2 emissions than traditional methods. The team achieved this by decomposing limestone to access calcium oxide (aka lime) without releasing carbon dioxide.

Hurtigruten Norway has released its concept of the eco-friendly cruise ship of tomorrow called Sea Zero that uses a raft of new technologies, including battery-powered propulsion and artificial intelligence, for zero-emission marine travel.

Concrete is one of the largest single sources of human-induced carbon dioxide emissions. Engineers at Washington State University have now developed a new method for making concrete that absorbs more carbon than it emits.

It's going to take decades to get aviation, shipping and long-haul transport down to zero emissions – but an interim solution is about to hit the market that can clean up big transport straight away, with no fleet changes – albeit in a strange way.

Australian architectural firm Whispering Smith's recently completed House A​ combines innovative, space saving design with carbon neutral credentials to create a blueprint for big living on a small footprint.

The CORE 9 prototype home is designed to not only be cost effective but also sustainably superior. It is part of one of Australia's first sustainable housing projects, which features 220 blocks of land where residents can only build a home that meets specific sustainable home design standards.

In a move that should give Lyft passengers that warm fuzzy feeling of helping the environment while getting from A to B, the ride-sharing company has announced that all its rides around the world will be carbon neutral – starting today.

The humble leaf, which collects sunlight and uses that energy to turn carbon dioxide into fuel for the plant, has inspired scientists. Researchers have developed a molecule that uses sunlight to convert the problematic carbon dioxide into carbon monoxide, which can then be stored as a fuel source.

The Bauhaus Barge has 25 square meters of PV panels on its side and top, which are said to provide enough free energy to power its motor, lighting and modern appliances.

Hahn Environmental CEO Allan Lear has pedaled over 1,600 km on his modified Stealth Bomber e-bike to set the longest distance traveled by an electric bike in a week.

The New Orleans Arcology Habitat (NOAH), is an arcology designed to house 40,000 residents along with all services and amenities that would allow them to live their entire lives within its walls if they so desired.
