Carbon dioxide traps the heat in the atmosphere of Venus and prevents it from escaping in to space (Venus contains a great amount of Co2 in its atmosphere). That's why, Venus is known as the hottest planet in the Solar System.
Both Mars and Venus have atmosphere made mostly of carbon dioxide. The atmosphere of Venus is much denser.
Venus
The atmosphere of Venus is mostly composed of carbon dioxide (CO2), with trace amounts of nitrogen and sulfuric acid droplets.

CO2
Mostly made of Carbon Dioxide(Co2).
Venus has a thick atmosphere composed mainly of carbon dioxide (CO2), along with trace amounts of other gases like nitrogen and sulfur dioxide. This dense atmosphere creates a strong greenhouse effect that traps heat and leads to extremely high surface temperatures on Venus.
Venus has the most carbon dioxide atmosphere among the planets in our solar system, with over 96% of its atmosphere composed of CO2.
It has a very thick atmosphere of Methane and CO2.
There isn't a lot of CO, but there is a lot of CO2 (carbon dioxide).
Too much CO2 makes the Earth warm up. On Venus the atmosphere is 93% CO2 and the temperature is 400-500 degrees.
No, Mercury is the closest to the sun, yet venus is hotter than mercury because there is more Co2 in the atmosphere.
