Not all carbon-capture projects pay off—Research maps the pros and cons of each to find clear winners and losers
Capturing carbon dioxide from the air or industries and recycling it can sound like a win-win climate solution. The greenhouse gas stays out of the atmosphere where it can warm the planet, and it avoids the use of more fossil ...
