What is a Carbon Footprint?
A carbon footprint is the amount of greenhouse gases—primarily carbon dioxide—released into the atmosphere by a particular human activity. A carbon footprint can be a broad meaasure or be applied to the actions of an individual, a family, an event, an organization, or even an entire nation. It is usually measured as tons of CO2 emitted per year, a number that can be supplemented by tons of CO2-equivalent gases, including methane, nitrous oxide, and other greenhouse gases.

1. Listen and read
1. Listen and read
Mai:
Nam, I read yesterday that we all have carbon footprint.
Nam:
Well, we all have footprints- we make them with our feet.
Mai:
Ha ha, I know that. But this kind of footprint is about the negative effect we have on the environment.
Nam:
Right, it’s in the news a lot these days.
Mai:
So our footprint is bigger when we use energy that produces carbon dioxide. That’s bad for the environment.
Nam:
So it’s better to have a smaller footprint, right?
Mai:
Right, Nam. Non-renewable energy sources like coal, natural gas, and oil produce a lot of carbon dioxide. Those sources are going to run out soon too.
Nam:
So, they are different to wind, hydro, and solar?
Mai:
Yes, they’re all sources of energy too, but they’re renewable. That means we can’t use them all up – they will last forever.
Nam:
Do you have a big carbon footprint, Mai?
Mai:
Mine’s small. I recycle the products I use and I go everywhere by bike. We have solar panels on our roof at home to catch the sun’s energy, too.
Nam:
Oh no! I think my footprint is big, and not just because of these big shoes!

Mai:
Nam, mình đã đọc vào hôm qua rằng tất cả chúng ta có một dấu chân carbon mới.
Nam:
À, tất cả chúng ta đều có dấu chân - chúng ta tạo ra nó với bàn chân chúng ta!
Mai:
Ha ha, mình biết. Nhưng loại dấu chân này là về hiệu ứng xấu mà chúng ta tác động lên môi trường.
Nam:
Đúng rồi, nó nằm trong tin tức nhiều ngày nay.
Mai:
Vậy nên dấu chân của chúng ta to hơn khi chúng ta sử dụng năng lượng tạo ra khí CO2. Điều đó thật xấu cho môi trường.
Nam:
Vậy thì tốt hơn là có một dấu chân carbon nhỏ hơn, phải không?
Mai:
Đúng rồi Nam. Năng lượng không tái tạo được như than, khí tự nhiên, và dầu sản xuất nhiều CO2. Những nguồn này sẽ sớm cạn kiệt.
Nam:
Vậy, chúng khác với gió, nước, năng lượng mặt trời phải không?
Mai:
Đúng thế, chúng cũng là tất cả các nguồn năng lượng. Nhưng chúng có thể tái chế. Điều đó có nghĩa là chúng ta không thể dùng hết chúng - chúng sẽ kéo dài mãi mãi.
Nam:
Bạn có một dấu chân carbon lớn phải không Mai?
Mai:
Của mình thì nhỏ. Mình đã tái chế những sản phẩm mà mình dùng và mình đi đến mọi nơi bằng xe đạp. Chúng mình có tấm pin mặt trời trên mái nhà để đón năng lượng mặt trời.
Nam:
Ồ không! Mình nghĩ dấu chân của mình lớn, và không chỉ bởi vì những đôi giày này!
