Comment no approach to measure carbon footprint? (Score 1) 302
Yes and no.
Various research and commercial projects are working on assessing environmental effects caused by commercial products and services in consideration of their whole lifetime, namely Life-Cycle Assessment (LCA). 'Environmental effects' here include resource consumption, carbon emission and other aspects of the production in every phase (e.g. factory installation, factory running, transportation and so on). Some researchers defined a framework to conduct an LCA in a systematic way so that the product or service is scientifically assessed and compared with equivalent product or service.
However, little efforts are done on assessing a company, not its products and services. This is probably because there is no fair way to compare companies. If you sum up all carbon emissions caused by all products/services of Google and GM, of course GM is much more to be blamed, but is it a fair comparison? Google and GM plays a very different role in our society, their products can't be replaced each other. The key of LCA is to compare 'equivalent' products. Are there 'equivalent' companies on the earth? No!
I don't agree with the tone that carbon footprint is not comprehensively measured, but agree that attributing environmental effects to companies makes no sense; it's currently used just for advocating a few specific companies with less emissions by their nature. Unfair.

an evidence that my country, Japan, shouldn't introduce DST. Japan is again considering to introduce DST even though we already concluded it won't work in Japan for cultural/geometrical reasons decades ago.
Pro claims that it's good for environment, but I haven't seen a single scientific evidence to support it. Con, like me, complains that DST will definitely confuse people and IT systems!
