German engineers have developed a process that turns algae into a carbon-sequestering replacement for steel and concrete that is as climate friendly as it is strong.

It isn’t too late to limit average global warming to 1.5°C without resorting to geoengineering, and deploying geoengineering technologies such as carbon capture storage (CCS) and solar radiation management (SRM) would be counterproductive and dangerously irresponsible, according to panelists at an April 25 webinar.

Solar and wind energy displace roughly 35 times as much carbon dioxide each year as carbon capture and storage (CCS) has sequestered in its entire history, DeSmog Blog reports, citing a new analysis by CleanTechnica.

Squamish, B.C.-based Carbon Engineering has received billionaire backing from Silicon Valley investors, netting US$68 million to build its first commercial-scale Direct Air Capture (DAC) facility to pull carbon dioxide out of the atmosphere.

The United Nations and Saudi Arabia were tagged as the biggest offenders late last week after the United Nations Environment Assembly (UNEA), under pressure from high-emitting countries, failed to make any progress on a plan to look into the risks of geoengineering technologies and address the need for stricter controls over their development.

Switzerland wants the world to talk about if and how to use untested technology that tampers with nature to slow climate change—and will ask the United Nations’ environment arm to take the lead. Geoengineering techniques that reflect away sun rays and suck carbon from the atmosphere have long been talked about as last-resort solutions to stem ...

The urgency and scope of the climate crisis are being needlessly exploited to drive fringe ideas like carbon dioxide removal (CDR) and solar radiation management (SRM) from the margins to the mainstream, according to a hard-hitting report issued last week by the Washington-based Center for International Environmental Law and Berlin’s Heinrich Böell Foundation.

Tropical staple trees rank #14 on Drawdown’s list of climate solutions. This option could eliminate 20.19 gigatons of atmospheric carbon dioxide at a cost of $US120.1 billion, producing savings of $627 billion.

Public support for different methods of removing carbon dioxide from the atmosphere depends in part on the extent to which they’re seen to tamper with nature, a group of four researchers concludes in a new paper.

One of the countless side discussions at this year’s United Nations climate change conference in Katowice, Poland focused on the growing acceptance that some method of capturing carbon dioxide—from the atmosphere, or at the point where it’s first emitted—will be necessary to keep average global warming within 1.5°C.

There’s no sign that the North American fossil industries’ attempts to develop viable carbon capture and storage (CCS) technology are paying off, and less justification than ever to keep up the effort, the Institute for Energy Economics and Financial Analysis concludes in a report released last month.

The 2.6-gigawatt Drax biomass- and coal-fired generating station in the United Kingdom is aiming for carbon-negative status with the launch of a carbon capture and storage (CCS) pilot project, a first of its kind in Europe.

Direct air capture (DAC) techniques to pull carbon dioxide out of the atmosphere may be on the cusp of the same drastic cost reductions that have brought solar, wind, and battery storage into the mainstream over the last decade, according to the chair of a recent U.S. expert panel on negative emission technologies.

The falling cost of renewable energy and energy storage, combined with the flexibility of Direct Air Capture (DAC) as a “negative emissions” option for sucking carbon dioxide out of the atmosphere, could point to a major opportunity to drive down carbon pollution and get climate change under control, according to a new paper in the ...

The UN published a summary on the science of 1.5°C global warming on Monday. It’s a big deal.
