This paper seeks to analyse the debate which has shaped Sweden's envir
onmental aid programme to Eastern Europe over the past four to five ye
ars, through focusing on two criteria: efficiency (both economic and e
nvironmental) and responsibility, Efficiency is used to refer to using
resources to obtain the maximum environmental benefit for resources e
xpended, Responsibility is examined here in terms of ultimate liabilit
y for the products or outcomes of aid given by one nation to another,
and how it affects the recipient nation's sovereignty. Do donors give
aid because they feel responsible on moral, historical or other ground
s? Long-range air pollution and cleaning up the Baltic Sea are used as
illustrative examples. The paper concludes by looking at the current
policy and practice of Sweden's environmental assistance to Eastern Eu
rope and how this has been influenced by the efficiency and responsibi
lity arguments.
