Our initiatives to become a more climate friendly family

The climate is debated eagerly and ideas to cut down CO2 emissions are constantly suggested. I have during a period of 3 years been reading about, what we as citizens can do on our own. It took me some time to get started, but during 2018 we did start on this as a family. All listed here can be taken as inspiration:

1. All bulbs have been replaced by savers.
2. Old dryer with high power consumption has been replaced by secondhand dryer with low power consumption.
3. We only eat meat once per week.
4. We have taken a decision to only buy secondhand, when possible.
5. We've planed vacation in 2019 not requiring a flight for transportation.
6. We've started sorting our trash. Yes it is a requirement in our municipality, but we are doing a little extra also making sure that plastic bags and hard plastic objects are delivered for reuse. 

What have you done?
