Foreword by the Secretary-General of the United Nations
By the late igj~osa, ir pollution had become the main environmental problem facing many countries
in Europe and North America, harming people’s health and damaging historic buildings and
monuments. Acid rain, brought on by contamination of the air, was taking a particularly heavy toll,
killing forests and lakes even in remote places far from industrial facilities.
In 1979,t he Member States of the UN Economic Commission for Europe adopted the Convention on
Long-range Transboundary Air Pollution. Negotiated under UNECE’s auspices, the Convention was the
first international environmental agreement to address this threat to human health and well-being.
After 25 years of international cooperation, its Parties are reaping the benefits of the cuts in air
pollution that they have made in compliance with the Convention’s provisions.
It is not just the people of Europe and North America who are benefiting. Other regions are keen to
emulate the successful combination of sound science and ambitious policy-making that underpins the
Convention, and adapt it to their particular needs. In addition, some of the Convention’s work, for
instance on persistent organic pollutants such as DDT and dioxins, has been used as a model for
worldwide environmental agreements.
The Convention has also galvanized action within UNECE. Since the Convention’s adoption, the
Commission has become a prolific environmental-lawmaking forum. It has negotiated four more
regional environmental conventions, covering international rivers and lakes, industrial accidents,
environmental impact assessment and public participation. All four have entered into force and are
contributing to making sustainable development a reality.
On the 25th anniversary ofthe Convention’s adoption, I congratulate all the stakeholders on the
achievements of the past quarter century, and encourage them to continue their efforts to find
innovative approaches to protecting the purity of the air we breathe.

Foreword by the Executive Secretary of the United Nations Economic
Commission for Europe
For 25 years the UNECE Convention on Long-range Transboundary Air Pollution has been one ofthe
main means of protecting public health and the environment from the harmful effects of air pollution
across the UNECE region.
With its eight protocols, the Convention has developed comprehensive and strong commitments
covering all major pollutants. It has thus significantly improved the air we breathe. For example,
compared to 1980,s ulphur emissions in Europe are down by 60 per cent while in Canada and the
United States they are almost halved. However, we still have much to do, in particular to meet the goals
set for the pollutants which migrate and affect millions of people living in cities throughout the world.
Over the past quarter of a century the politics of Europe has changed. These changes have not altered
the political willingness of member States to work together under the convention. On the contrary,
the countries of the region increasingly share the conviction that further cooperation is needed to
combat air pollution, as its impact on both human health and the future of the planet is a major
preoccupation of public opinion.
The Convention and its protocols have set targets and defined legislative and other measures required
for meeting them. A major challenge now is to implement these measures effectively, in particular in
South-East Europe, Eastern Europe, the Caucasus and Central Asia, where countries need special
support, as their industries develop and road traffc expands. I therefore welcome the Convention’s
increasing emphasis on protecting people and their environment in these subregions.
For its part, the UNECE secretariat will spare no effort in providing continued support for the work
that the Parties to the Convention will undertake in the future.
I wish to congratulate all the stakeholders on the achievements of the past 25 years and look forward
to further successes in meeting the challenges ahead, which, in many ways, are even more complex
than those we have dealt with since the adoption of the Convention.

Preface
This book, like the Convention on Long-rangeT ransboundary Air Pollution and its protocols, has been
an international cooperative effort. The teams of authors have revisited the history of acid rain and air
pollution in the UNECE region, an area that extends from the United States and Canada in the West to
Central Asia in the East. But the Convention is not just history; the book also considers its future.
The memories, perceptions and reflections of the contributors have been brought together here to
mark the 25th anniversary of the Convention. The contributors were or still are involved in the work of
the Convention as government officials, members United Nations staff, national experts from
institutes and universities or representatives of international NCOs.
Nearly 60 authors and other contributors have collaborated on this book, each with experience in one
or more areas of the work under the Convention. They have contributed to the book in a private
capacity so the views expressed are their own.
Without any exception, all who were asked were eager to contribute. We realize that no doubt others
would have been equally willing; however, we hope that they will understand the limits to our ability to
coordinate such a large number of contributors. Even so, the enthusiastic support given by the
authors made it a pleasure for us as editors, assisted by the UNECE secretariat, to complete our task.
It was hard work but enjoyable.
This book pays tribute to all our colleagues, past and present, who have helped to develop the
Convention and its protocols and move from the ‘Fruits of the Cold War’ to ‘Blue Skies Forever’.
