Cách giảm thiểu dấu chân carbon

bật điều hòa thấp, dùng đồ điện tử lâu hơn, lốp xe bơm đúng...
Dear Dan,

I’m very environmentally conscious (ý thức về môi trường) and try to minimize (giảm thiểu) my carbon footprint wherever possible. Working from home (làm ở nhà) has been wonderful for many reasons. I’m especially happy to see fewer people driving. Do you have any other suggestions for how we can curb our environmental impact while confined to our homes?

When we think of addressing big problems, such as environmental impact (tác động môi trường), it’s natural to look for big solutions, such as driving less, at the expense of multiple, smaller solutions that can add up over time. We tend to overlook easy things we can do that seem small or whose effects are not immediately clear.

For example, think about the carbon footprint associated with something as small as Internet usage. The electricity that powers data centers accounts for about 1% of global energy demand—and that figure does not even include these facilities’ land and water use. Video transmission is the biggest problem. A group of researchers studied the impact of online streaming and video-conferencing. They found that if a person streamed at high quality for four hours a day, switching to standard definition would reduce that person’s monthly carbon footprint by the same degree as reducing driving by 93 miles a month.

Of course, video streaming is just one example. Lots of small actions, such as turning the thermostat down a bit, keeping electronics for longer and making sure our tire pressure is set correctly can also make a difference, and we should consider these when we think about the changes we can make.
