Could artificial trees be part of the climate change solution?
In the fight against climate change, trees are an ally. They suck in carbon dioxide, reducing the harmful greenhouse gases. But there’s a problem: we’re asking them to work overtime. Trees can’t absorb enough of the carbon dioxide humanity is throwing at them unless we turn every inch of Read More...
Using technology to keep carbon emissions in check
The Paris agreement to curb climate change calls for a dramatic shift away from fossil fuels and the greenhouse gasses they emit, especially carbon dioxide. Switching to renewable energy helps but that won't happen fast enough to keep temperatures from rising to dangerous levels. That's why Read More...
Why we shouldn't forget about carbon capture and storage
The climate conference in Paris showed us there is massive momentum these days to reduce carbon emissions. That's great. But there's less talk about another, more controversial solution: removing carbon from the air, by storing it, and using it to generate other ingredients. The world's largest Read More...
Converting carbon dioxide into alternative fuels with underwater solar cells
Stanford engineers are looking beneath the waves for a way to turn greenhouse gas emissions into something useful. The engineers have built energy-efficient, corrosion-protected underwater solar cells that produce energy to create a chemical reaction that converts greenhouse gases into “solar Read More...
France to spend billions on African renewable energy projects
France plans to spend billions of euros in renewable energy and other environmental projects in its former west African colonies and across Africa over the next five years, President François Hollande said on Tuesday. Africa produces little of the greenhouse gases such as carbon dioxide, produced Read More...
Washington project ensures forest stores carbon for decades
Half a small forest still standing near Mount Rainier faced clear-cutting before an effort in Washington state saved the decades-old trees and allowed Microsoft to help finance the project to offset its carbon footprint. The effort by two environmental groups keeps 520 acres of Douglas fir and Read More...
How community rights can prevent deforestation
This article is published in collaboration with Trust.org (Thomson Reuters Foundation). Ensuring rainforest communities have secure land rights can reduce deforestation and land-use conflicts and prevent tens of millions of tonnes of carbon dioxide emissions each year, new research shows. The World Read More...
Making green fuels, no fossils required
Using solar or wind power to produce carbon-based fuels, which are commonly called fossil fuels, might seem like a self-defeating approach to making a greener world. But when the starting material is carbon dioxide, which can be dragged out of the air, the approach is as green as it gets. The Read More...
What are the health benefits of renewable energy choices?
This video breaks down the science behind our paper on the health benefits of a low carbon energy policy, and explores how renewable energy is good for our health. Generating electricity from low-carbon energy sources and cutting energy demand reduces the need for fossil fuel power generation, Read More...
The world's first commercial carbon capture plant will turn pollution into cash
If we can efficiently capture CO2 from the air, that would solve a lot of problems. By next summer, the world's first commercial plant that captures carbon dioxide directly from air will begin operation in Switzerland. A handful of other startups are working on similar technology, but Climeworks AG Read More...
