Literally, low carbon means lower greenhouse gas emissions. In addition, low carbon is now synonymous with environmental protection, which can be extended to recycling, energy saving and emission reduction. Nowadays, the concept of low-carbon life has attracted more and more attention. After the Copenhagen Climate Conference, the 20 10 Shanghai World Expo also put forward a low-carbon slogan. Many buildings, designs and concepts revolve around the slogan of low carbon, trying to create a harmonious and natural environment. Besides the World Expo, there are many other activities with the theme of low-carbon life. For example, Gymboree's low-carbon caravan in early education achieves the purpose of environmental protection by replacing reusable items in the baby's daily life, while BMW's low-carbon first-year name-seeking activities and advocating the concept of scientific and technological environmental protection are all very good low-carbon activities. In a sense, low-carbon life is not only a fashion, but also the necessity of the development of human civilization to a certain stage and the only way to strive for a better tomorrow.
