Cement production makes more CO2 than all the trucks in the world

Low-carbon geopolymer cement can reduce CO2 by up to 90 percent. But it costs three times as much as the usual cement and nobody is buying it.

CO2 levels just reached the highest level in human history

For the first time since humans existed on earth, carbon dioxide has exceeded 415 parts per million.

Scientists turn carbon dioxide back into coal

Scientists have harnessed liquid metals to turn carbon dioxide back into solid coal, in research that offers an alternative pathway for safely and permanently removing the greenhouse gas from our atmosphere.

Greenhouse gas levels reach record highs, UN says

Average concentrations of carbon dioxide hit new highs of 405.5 parts per million (ppm) in 2017, up from 403.3 ppm in 2016 and 400.1 ppm in 2015, levels not seen for millions of years.

Cities With The Biggest Carbon Footprints

According to the latest study by the Norwegian researchers - Seoul (South Korea), Guangzhou (China) and New York City leads the world in its global carbon footprint.

Higher CO2 levels may lead to decreased nutrients in rice

Scientists have discovered that increased levels of atmospheric carbon dioxide may lead to lesser amounts of nutrients, such as essential B vitamins, in rice.

18-year old invents cheaper CO2 capture tech

18-year-old Ethan Novek's carbon dioxide (CO2) capture technology stands out from the rest because it could capture CO2 at about $10 per metric ton – around 85 percent less than the industry standard.

Greenhouse gas concentrations surge to new record

Over the last 800,000 years, pre-industrial atmospheric CO2 content remained below 280 ppm, but it has now risen to the 2016 global average of 403.3 ppm.

Rising temperatures are curbing ocean’s capacity to store carbon

Study finds large amounts of carbon dioxide, equivalent to yearly U.K. emissions, remain in surface waters.

World’s first commercial carbon-sucking plant goes live in Zurich

A company has unveiled the world’s first Direct Air Capture (DAC) commercial plant on top of a waste recovery facility in Zurich, Switzerland.

Explained: Greenhouse gases

Carbon dioxide isn't the only one that matters, and the gases vary widely in potency and duration.

'New Era of Climate Change Reality,' WMO Warns

With atmospheric carbon dioxide concentrations having reached 400 ppm 2015 and with no signs of them abating in 2016 the World Meteorological Organization (WMO) said that "a new era of climate change reality" is upon us.

Scientists just accidentally discovered a process that turns CO2 directly into ethanol

If scientists can figure out how to convert atmospheric carbon dioxide into fuel - and do it at an industrial scale - it would, quite literally, change the world.

Engineered Bacteria Uses Sunlight to Turn CO2 Emissions into Methane

Scientists have engineered a bacterium that can take carbon dioxide from the air and turn it into fuel in a single enzymatic step.

How to make plastic from CO2 and plants

A novel way to make plastic from carbon dioxide (CO2) and inedible plant material could provide a low-carbon alternative to plastic bottles.
