This startup turns CO2 into jet fuel and plastics
The impressive Bay Area-based startup, Twelve, is on a mission to replace petrochemicals at a large scale so that it can significantly slash global energy emissions—something that we urgently need to do for our species’ survival. Converting CO2 into something useful How will they do it? Read More...
Europe’s first biorefinery uses algae to make jet biofuel
The global aviation industry is responsible for more than 2 percent of human-produced carbon dioxide emissions. To put a dent in that statistic, scientists have been actively searching for cost-effective and eco-friendly aviation fuels derived from natural resources. In recent years, microalgae Read More...
City trees may trap more CO2 than we thought
It’s becoming common knowledge at this point that trees greatly benefit cities and the people that call them home. City trees and urban green areas regulate temperature, improve mental health and reduce loneliness for urbanites, clean the air and even reduce crime rates. Our tall, green friends Read More...
Healthier soil means healthier food
We’ve written in the past about regenerative agriculture and how it benefits the planet. It’s a simple system of farming that involves plowing less, using cover crops, and diversifying to create healthier soil. The practice has made products that are 100 percent carbon negative, and it has Read More...
This system takes CO2 from the air by taking it from the sea
The world over, researchers and scientists are looking for effective and economical ways to pull CO2 out of the air to mitigate the effects of climate change. There are many promising solutions out there, but the amount of CO2 that needs to be withdrawn is substantial and the process of pulling it Read More...
Four ways to clean your house plants
Cleaning your plants may seem trivial, but there is scientific support behind keeping your leafy friends squeaky clean. The stomata and chlorophyll of plants, which absorb carbon dioxide and help perform photosynthesis, can be clogged and blocked by dirt and dust. Cleaning your plants helps ensure Read More...
This Kenyan community regrew its forest
At The Optimist Daily, we love stories fighting deforestation or spurring reforestation. Forests are our friends. They host myriad wildlife, foster ecological diversity, consume carbon dioxide, and breathe out oxygen. They also do a lot of heavy lifting when it comes to reducing floods. In Read More...
This bacteria "eats" carbon emissions and makes useful chemicals
Scientists at LanzaTech in Illinois have engineered some exciting new bacteria that actually transform carbon dioxide into ethanol and isopropanol, compounds used in paint remover and hand sanitizer. Michael Köpke and his colleagues went on a hunt for strains of the ethanol-producing bacterium, Read More...
This startup uses electrochemistry to capture carbon
A tricky part of carbon capture technology is the energy required to pull it off. Many critics, while agreeing on the need to pull carbon dioxide out of the air, say that existing technologies might produce more emissions than they remove. Now, startups are getting creative to optimize carbon Read More...
Submarine to explore the underside of Greenland’s glaciers in a first
Scientists are desperately trying to save the world’s glaciers. As they hold a large amount of water and carbon dioxide, it is essential that we slow the demise of these structures for the climate's sake. We’ve previously written about a group using special mountain blankets on Mount Titlis Read More...
