- LCA is used to study the impact on a product.
- LCA is one of the exhibitions at this year's fair.
- LCA can help manufacturing industries decrease carbon release a lot.
- LCA advises industrial customers to focus on the initial investment. Now, answer this question: Read the following article and answer the question. Article: "Developed and developing nations can learn from each other seeking a low-carbon economy. In terms of energy saving and green economy, China doesn't _ developed nations," said Zhou Changyi, director of the energy saving department of the Ministry of Industry and Information Technology. "While we can learn many aspects from developed nations, they also should learn something from us, such as water conservation," Zhou said in a speech during the new Path of China's Industrialization forum at the ongoing China International Industry Fair. He said industrialized nations and China are dealing with different issues to fight climate change. The United Kingdom, for example, is concerned about transport, buildings and new energy in reducing carbon emissions. For China, the most urgent task is how to realize new type of industrialization and avoid mistakes that other countries made when they industrialized. Swiss power and automation technology group ABB called for a stronger focus on product life-cycle assessment, or LCA, which is used to study the environmental impact of a product from the research and manufacturing stage through its usage and recycling. Tobias Becker, head of ABB' s process automation division for North Asia and China, said LCA is an effective tool in helping manufacturing industries to reduce carbon emissions. LCA shows that industrial customers should focus on a product's environmental impact throughout its life-cycle instead of on its initial investment. Richard Hausmann, North East Asia CEO of Siemens, said, "The color of future industrialization is green. " The Germany company recently announces that it wants to receive orders worth more than 6 billion Euros ( US 8. 8 billion) for intelligent power networks, Smart Grid, over the next five years. Siemens has set a 20 percent market share target for the global smart grid business. A smart grid delivers electricity from suppliers to consumers using digital technology, advanced sensors specialized computers that save energy, reduce costs and...

Article: During the school year many parents take on the role of driver as they drive their children from one lesson to another .Understandably so. Many of us want our children to have a little taste of everything, from organized sports to music, dance and more. But we can overdo it, leaving our children feeling a little burnt out, and according to parent educator Diane Loisie ,it's their school work which suffers the most. "After school, if they're busy in a number of sporting events, besides they need to do their homework, then the time they'll feel sleepy is in the classroom. Your child needs free time. So if you're filling up that after school time, then it's during the day that they're going to be taking a break." Professor Claire McDermott agrees that there's a lot to be gained from sometimes putting those scheduled lessons and activities away. "Relaxing time is important for children. It's time just to do the things they want to do. A child can go up to their room, or they can play around. It doesn't look like productive time; parents certainly wouldn't be saying 'Wow, are they ever learning things now?' But this relaxing time gives both the body and the brain just a wonderful chance to relax after a day. It helps a child prepare for sleep, but it also helps to understand the learning that's gone on that day." It's hard to prevent signing our kids up for some activities and lessons. After all, many of us want our children to have a head start in life and the chance to join in great activities in the arts or sports is a part of that. However, Loisie feels that in the long run most children feel better with just a few key activities because it gives them an opportunity to master them. "When we get our children in too many activities because we want our children to experience everything, then what we're doing is setting them up not to be good at one thing or gaining a skill." So choose your children's activities wisely. It may be one of the best things you've ever done for your kids... and for the family drivers!
