Main sources of $\ce{CO2}$ emission to the atmosphere

What are the main sources of $\ce{CO2}$ emission to the atmosphere? I know that the answer would probably be from the electricity sector and transportation but wouldn't most of the carbon dioxide produced from power plant be captured and stored by the CCS technology? Is it because not all the plants has the CCS technology to capture the $\ce{CO2}$? Or are there any scenario where CCS technology cannot be used e.g cars?

• It seems like you are assuming most power plants have CCS. Quite the opposite. see globalcarbonproject.org and en.wikipedia.org/wiki/… – farrenthorpe Sep 2 '15 at 17:19
• Do you know the reason why? Is it because of the cost? – Innocent98 Sep 3 '15 at 2:59
• There are many reasons... first of all your production goes down due to the increased energy cost of trapping CO2 and converting to liquid. Second there aren't many places that are sited where CO2 could be injected underground safely. Third, it's a new technology still being developed... mainly it is used as a test project. Fourth, there is a lot of animosity because it isn't considered a viable climate solution by many people. – farrenthorpe Sep 6 '15 at 19:24
