'LIFE-CYCLE ANALYSIS'
56. One aspect of Integrated Product Policy which
gave rise to some concern amongst witnesses was the use of 'life-cycle
analysis' (LCA). The consultation paper Consumer Products and
the Environment says, "The Government believes that environmental
policies about products should be taken on the basis of sound
science."[92]
We agree. However, as the consultation paper goes on to point
out, "this principle is rarely as straightforward as it sounds
in the case of products."[93]
LCA is perhaps the most thorough and scientific way of assessing
where the most serious environmental impacts of a product occur,
and therefore what measures should be taken to address them. However,
it is important that the effort put into such assessment is proportional
to the gains for the environment which can be made as a result.
Sainsbury's gave us the example of the application they had made
of formal life-cycle analysis to fresh and long-life milk packaging.
This, they said, was "a very cumbersome, time consuming and
expensive tool for decision making. In retrospect the final recommendations
could have been identifiedin rough termsfrom an
analysis of the summary data as available at the start of the
project."[94]
57. It is therefore important that LCA be used with
common sense. Dr Berkhout of SPRU said, "we would stress
much less the scientific precision of the analysis of the environmental
impacts and resource use of product systems than the formulation
of a process by which some form of analysis is provided. Sometimes
that can be as simple as a back-of-the-envelope calculation."[95]
Similarly, Sainsbury's concluded that 'life-cycle thinking' was
a more cost and time-effective approach than full life-cycle analysis.[96]
Scientific analysis is important in assessing priorities for action:
as Dr Berkhout told us, "The question facing policy-makers
and producers is: what is the alternative? The alternative is
prejudice. Clearly, one will make wrong decisions if one always
accepts common wisdoms about the environmental impacts of different
product systems. One needs science and a rigorous framework to
try to understand the environmental impact of behaviour through
the consumption of products."[97]
However, it is our conclusion that life-cycle analysis should
be used with an understanding that it is only a means to an end:
that end being the identification of the priorities for action
towards more sustainable patterns of consumption. As such, it
may be appropriate to use simplified versions of the approach
for products where the environmental characteristics or implications
are clear-cut.
58. As part of the effort to educate consumers towards
more sustainable patterns of consumption and as a safeguard on
their accuracy, we recommend that, wherever possible, details
of life-cycle assessments be made publicly available. This
will help to make consumers more aware of the effect of the products
they buy on the environment, will open such analyses to debate
and scrutiny and should help to disseminate best practice.
59. A final point about product policy is that moving
towards 'sustainable patterns of consumption' means taking account
not just of environmental issues, but also of social and ethical
ones. In this context we welcome the recent report of the Trade
and Industry Committee on Ethical Trading. The Body Shop noted
that "in the context of the EU ecolabel, the various expert
groups and the competent bodies singularly failed to develop an
LCA methodology which would adequately reflect societal values
in the process of developing label criteria".[98]
B&Q said, "We do not have confidence in 'life-cycle assessment'.
It places too much emphasis on energy and aspects of the product's
life-cycle which can be measured numerically. You cannot measure
child labour, but it is the key issue with rugs."[99]
We commend the inclusion of a note on 'social and ethical dimensions'
in the Government's consultation paper on consumer products and
the environment. We further hope that these issues will be directly
addressed within the context of policies on consumer products.
