工业领域的重要性
Importance of Industrial Sector
• 全球范围内，工业领域占全球总能耗和与之相关的CO2排放量的
37%。
Globally, the industrial sector accounts for 37% of energy use
and energy-related CO2 emissions
• 这一比重在发展中国家更高，因为这些国家的基础设施建设和城
市化进程对工业原料的需求更大。
Share is higher in developing countries, where infrastructure
construction and urbanization places heavy demands on
industrial materials
• 取决于定义的不同，中国的工业领域占了全国总能耗的60%到
70%。
Depending upon how it is defined, industrial sector in China
accounts for 60% to 70% of all energy consumption

环境挑战
The Environmental Challenge
• 大规模的工业生产和高能耗造成了严重的环境污染
High levels of industrial production and energy use can
have serious environmental consequences including:
• 空气污染 air pollution
• 水污染 water pollution
• 工业废物 industrial waste
• 温室气体排放带来的全球气候的变暖
greenhouse gas emissions contributing to global
warming
• 不挖掘提高能效的潜力也相当于造成经济损失
Untapped potential energy efficiency improvements also
represent economic losses
• 能效的提高将减少污染物的排放和节约成本。
Improved energy efficiency will reduce many of these
emissions and save money
5
如何降低工业能耗
How to Reduce Industrial Energy Use
• 转向能耗较低的产业 Shift to Less-Intensive Industries
— 在工业化阶段，这一措施难以执行 Difficult during
industrialization phase
— 中国已是“世界工厂” China is “world’s factory”
• 改善工业基础 Improve Industrial Base
— 新设施：设计标准（执行力是关键）
— New facilities: design standards (enforcement is important)
— 现有设施：更新老旧的，低效的设备，淘汰效率最低的设备设施
— Existing facilities: replace old, inefficient equipment, close down
most inefficient facilities
• 所需条件：Requires:
— 新的，高效的技术 New, efficient technologies
• 可从国外引进或运用国内技术 Import or produce domestically
— 创新的，有效的政策和方案
— Innovative and effective policies and programs

•
这比预期要好，是因为工业领域低估了他们能够通过提高能耗实现的减排量。
Sectors did better than expected because industry underestimated what they could
achieve via energy efficiency
•
工业能够实现每年节约8亿3千2百万美元，是因为达到了英国气候变化协议的目标。此外，
还有通过气候变化税所实现的节能。
Industry is saving over $832 M/year on the energy it has not bought as a result of meeting
the CCA targets, in addition to the savings on the Climate Change Levy itself
