“低碳生活”虽然是个新概念,提出的却是世界可持续发展的老问题,它反映了人类因气候变化而对未来产生的担忧,世界对此问题的共识日益增多。人类意识到生产和消费过程中出现的过量碳排放是形成气候问题的重要因素之一,因而要减少碳排放就要相应优化和约束某些消费和生产活动。 Although the “low-carbon life” is a new concept, what it proposes is the old problem of sustainable development in the world. It reflects the concern people have over the future due to climate change. The consensus on this issue in the world is increasing day by day. Human beings are aware that excess carbon emissions in production and consumption are one of the important factors that cause climate problems. Therefore, to reduce carbon emissions, some consumption and production activities should be optimized and constrained accordingly.
