![]() A metric ton (ton) is 10% more than a standard ton (2000 lb). Human activities emit about 40 gigatonnes (Gt), or 40 billion metric tons of carbon dioxide per year, into the Earth’s atmosphere. Blue Planet’s CEO, Brent Constantz, recently spoke to one of my finance classes, and below I’ll summarize some of the key points he made in his presentation. The Pittsburgh plant is owned and operated by the firm Blue Planet Systems. In this post, I want to share with readers what I recently learned about “making lemonade from lemons” while teaching climate finance to students at Santa Clara University, south of San Francisco. One indication of whether it might be possible on a large scale to make a difference in climate change includes the results of a pilot plant located in Pittsburgh, California, north of San Francisco. The lemonade in question includes the degree to which it may be possible to capture carbon dioxide from power plants burning fossil fuels, and to isolate the carbon dioxide captured within concrete in a way that is both sustainable and economical. ![]() However, there is a good chance of being able to take those lemons and make lemonade from them. Until now, the production of cement and concrete has been the real lime for the Earth’s climate. This is important because on a global basis, the industry that produces cement and concrete generates between 7 and 8% of annual carbon dioxide emissions. The production of cement and concrete has been and still is a major contributor to anthropogenic climate change.
