According to the Carbon Footprint Calculator in the OP's link, my family (me, wife, 9-year old daughter) has the following footprint:
I estimated the amount of energy we used for heating (10,000 kWh), based on our previous house (72 m2) in the Netherlands, even though our current apartment measures 45 m2 and has better insulation. Because we occasionally have family coming over, I added their travel footprint to ours, and for secondary I chose slightly worse options.
For the past couple of months we've been building a house, which takes quite a bit of energy, but we built with at least concrete as possible, and the house is made from wood which also stores CO2. As the house is supposed to be very energy efficient and has a 5 kWp solar array (which has produced 500 kWh so far), and we're planning to do a lot of gardening, I have hopes that the carbon footprint of House and Secondary will be reduced significantly.
We're also planning on cutting back on driving as much as possible. Even though our car is pretty efficient and uses CNG, 15,000 km per year is way too much. We're buying good bikes in a couple of months, possibly an electric bike for transports, and this should cut out most of our short trips. Our goal is to get the driving to 5000 km per year or less.
In short, this is where I would like us to go in the next 3 years:
