Climate and tire pressure can have a big impact on fuel economy. Along with the driver's style and route.
The Element is no longer available in the US, but I don't know about the rest of the world. The CR-V is one of Honda's bread and butter models, and the averages here are going to include newer ones with all the latest tech for efficiency.
2011 was the last year for the Element. The squared off back end is bad for aerodynamics, and it appears to weight about 200 pounds more than the CR-V. These explain how the CR-V gets better EPA ratings. The Element was available with a manual, which does mean better control for fuel economy though.

What is your daily drive like? If lower speed roads, or mostly traffic, the difference in city ratings is close enough that I wouldn't worry about the fuel economy between the models. If highways, the CR-V gets a bigger advantage. If snow is only a one or two times a year occurance, stick to the FWD for the fuel savings.
Did you track fuel economy for your current car? We can calculate some estimates for the Honda's from its data.
