THE ASSESSMENT OF THE VIENNA CONVENTION FOR THE PROTECTION OF THE OZONE LAYER DEPLETION

Abstract

The Vienna Convention for the Protection of the Ozone Layer 1985 occupies a
foundational place in the development of modern international environmental law.
It emerged at a moment when scientific concern about anthropogenic damage to
the ozone layer had become compelling, yet the political conditions for a stringent
global control regime had not fully matured. The Convention was therefore drafted
as a framework treaty rather than as a directly prohibitory instrument. This article
argues that the Convention’s enduring significance lies in its constitutional and
institutional role: it created a legal platform for research, monitoring, cooperation,
information exchange, and later protocol-making. At the same time, its principal
weakness was its lack of immediate substantive obligations. It did not prescribe
quantified reductions, establish a robust compliance mechanism, impose trade
sanctions, or create a dedicated financial structure for implementation. A
comparative legal and policy analysis with the Montreal Protocol reveals that the
practical success of the ozone regime depended less on the Vienna Convention
standing alone than on the later hardening of obligations through protocol-based
controls, reporting duties, differentiated commitments, and technological and
financial support. The Convention should therefore be understood as both an
achievement and a limitation: an indispensable beginning, but not a sufficient legal
answer to ozone depletion.
