In this article, I focus on carbon capture and storage (CCS), a controversial climate change mitigation technology that operates by collecting carbon dioxide from point sources and depositing it in underground locations, such as depleting oil reservoirs. Specifically, I investigate the ways in which...

Carbon Dioxide or CO2 is a greenhouse gas that is natural and harmless in small quantities, but as levels rise it can affect productivity and sleep. Most commonly produced indoors by the air we exhale, CO2 levels concentrate indoors with less ventilation....
Carbon dioxide (or CO2) is a colourless and odourless naturally occurring gas in the earth’s atmosphere which is made up of one carbon atom and two oxygen atoms. As a greenhouse gas (GHG), it traps heat, making sure the planet isn’t uninhabitably cold. However, fast rising levels of...
