In my everyday life，I am on an ongoing journey to figure out different ways to reduce my carbon footprint on the planet.A carbon footprint is the measure of influence our activities have on the environment，in particular climate change.It is calculated by the amount of greenhouse gas we produce in our daily lives.Fortunately，nowadays it is much easier to make eco-friendly lifestyle choices than，let's say，20 years ago.But one question has been on my mind a lot lately：is it better to buy new eco-friendly products or used traditionally produced goods？
After doing some research，I have decided that some things are better new and others are better used.Let me try to explain.
A carbon footprint is made up of two parts，the primary footprint and the secondary footprint.The primary footprint is a measure of our direct emissions （排放） of carbon dioxide （CO2） from the burning of fuels，including household energy consumption and transportation.The secondary footprint is a measure of the indirect CO2 emissions from the whole lifecycle of products we use-those related to their production and breakdown.
Based on this understanding，we have a good deal of control and responsibility over our carbon footprint.Things like dishes，clothes and furniture fall into the "secondary footprint" group，so less is more and we can focus on finding used goods to avoid the added production.However，for the car and the other appliances （設(shè)備） that we need we can go with new，energy-saving models.I heard somewhere that electronics and appliances give off 90% of their carbon footprint after they leave the factory.So it seems most reasonable to go for the energy-saving models.The main concern here is the amount of energy that goes into the making of new products and whether or not that extra carbon is worth the footprint the product will make once it gets to you.

C．Buying new but cheap clothes.
D．Buying new wooden furniture.
（4）"The footprint" underlined in the last sentence refers to the CO2 produced in AA.
