Arctic tundra now emits planet-warming pollution, federal report finds
Arctic tundra, which has stored carbon for thousands of years, has now become a source of planet-warming pollution.
Striving for a sustainable Lifestyle
Residential and commercial buildings account for almost a third of U.S. greenhouse gas emissions.
Scientists say they’ve found a way to recycle cement from demolished concrete buildings.
A world-first study has found enzymes from the prickly paddy melon weed can create a sustainable alternative to cement.
The Lower Sioux tribe in Minnesota is pioneering the country’s first integrated hempcrete operation, transforming industrially-grown hemp into a construction material for sustainable, healthy housing. This initiative, unique in the U.S., also aims to tackle the tribe’s critical shortage of jobs and housing, while acting as a model for other Indigenous tribes.
A team of experts from EPFL, ETH Zurich, and Archiplein has developed a new type of non-reinforced concrete from stone offcuts. Using methods found in historical archives, the team reduced their use of carbon-intensive cement. They built and tested six load-bearing walls using recovered stone-quarry waste and three types of mortar-based binders.
Concrete is the second most widely used material on Earth, behind only water. But concrete has also historically been detrimental to our environment.
One of the consequences of rising CO2 levels in our atmosphere is that levels also rise proportionately in the ocean, harming wildlife and changing ecosystems.
