P1:水泥二氧化碳排量大及其原理
P2:水泥三巨头承诺减排,但是水泥需求的稳固增加,the industry’s environmental headaches are only likely to grow.
P3:水泥三巨头承诺减排量
P4:The cuts come in three main areas
-Efficiency
-Fuel substitution
-Additivied mixture
P5: 对应P4三点的局限性
-效率提升空间不大
-燃烧废物产生毒气
-building codes limit the extent to which cement can be diluted with additives.
P6:另一局限性these measures yield only marginal benefits
-需求的增长比减排速度快,排放总量还是在增加
-举例Lafarge,削减富裕国家的排放量,同时扩大新兴国家市场
P7:Cement firms see no way to alter the basic chemistry of cement-making
-carbon capture
-stronger and more flexible varieties of cement and concrete
Bruno观点:使用miracle product来提高能源利用率,并且从城市建筑和规划上减少对水泥的需求
P8:David观点:the industry will ultimately need to come up with a substitute for cement
举例Lafont在实验室敦促科研 |
