PROTOCOL TO THE 1979  
          CONVENTION ON LONG-RANGE TRANSBOUNDARY AIR POLLUTION  
                                  ON  
      THE REDUCTION OF SULPHUR EMISSIONS OR THEIR TRANSBOUNDARY FLUXES  
                     BY AT LEAST 30 PER CENT (1985) 

ENTERED INTO FORCE: 2 September 1987 

The Parties, 

Determined to implement the Convention on Long-range Transboundary Air 
Pollution, 

Concerned that the present emissions of air pollutants are causing 
widespread damage, in exposed parts of Europe and North America, to 
natural resources of vital environmental and economic importance, such as 
forests, soils and waters, and to materials (including historical 
monuments) and, under certain circumstances, have harmful effects on 
human health, 

Aware of the fact that the predominant sources of air pollution 
contributing to the acidification of the environment are the combustion 
of fossil fuels for energy production, and the main technological 
processes in various industrial sectors, as well as transport, which lead 
to emissions of sulfur dioxide, nitrogen oxides, and other pollutants. 

Considering that high priority should be given to reducing sulfur 
emissions, which will have positive results environmentally, on the 
overall economic situation and on human health, 

Recalling the decision of the United Nations Economic Commission for 
Europe (ECE) at its thirty-ninth session. which stresses the urgency of 
intensifying efforts to arrive at coordinated national strategies and 
policies in the ECE region to reduce sulfur emissions effectively at 
national levels, 

Recalling the recognition by the Executive Body for the Convention at its 
first session of the need to decrease effectively the total annual 
emissions of sulfur compounds or their transboundary fluxes by 1993-1995, 
using 1980 levels as the basis for calculations of reductions, 

Recalling that the Multilateral Conference on the Causes and Prevention 
of Damage to Forests and Water by Air Pollution in Europe (Munich, 24-27 
June 1984) had requested that the Executive Body for the Convention, as a 
matter of highest priority, adopt a proposal for a specific agreement on 
the reduction of annual national sulfur emissions or their transboundary 
fluxes by 1993 at the latest, 

Noting that a number of Contracting Parties to the Convention have 
decided to implement reductions of their national annual sulfur emissions 
or their transboundary fluxes by at least 30 percent as soon as possible 
and at the latest by 1993, using 1980 levels as the basis for calculation 
of reductions, 

Recognizing, on the other hand, that some Contracting Parties to the 
Convention, while not signing the present Protocol at the time of its 
opening for signature, will nevertheless contribute significantly to the 
reduction of transboundary air pollution, or will continue to make 
efforts to control sulfur emissions, as stated in the document annexed to 
the report of the Executive Body at its third session, 

Have agreed as follows: 

                              Article 1 

                             Definitions 

For the purposes of the present Protocol,

Pollution, adopted in Geneva on 13 November 1979; 

2. "EMEP" means the Cooperative Programme for Monitoring and Evaluation 
of the Long-range Transmission of Air Pollutants in Europe; 

3. "Executive Body" means the Executive Body for the Convention 
constituted under article 10, paragraph 1 of the Convention; 

4. "Geographical scope of EMEP" means the area defined in article 1, 
paragraph 4 of the Protocol to the 1979 Convention on Long-range 
Transboundary Air Pollution on Long-term Financing of the Cooperative 
Programme for Monitoring and Evaluation of the Long-range Transmission of 
Air Pollutants in Europe (EMEP), adopted in Geneva on 28 September 1984;

                              Article 2 

                          Basic provisions 

The Parties shall reduce their national annual sulfur emissions or their 
transboundary fluxes by at least 30 per cent as soon as possible and at 
the latest by 1993, using 1980 levels as the basis for calculation of 
reductions. 

                              Article 3 

                         Further reductions 

The Parties recognize the need for each of them to study at the national 
level the necessity for further reductions, beyond those referred to in 
article 2, of sulfur emissions or their transboundary fluxes when 
environmental conditions warrant. 

                              Article 4 

                    Reporting of annual emissions 

Each Party shall provide annually to the Executive Body its levels of 
national annual sulfur emissions, and the basis upon which they have been 
calculated. 

                              Article 5 

                 Calculations of transboundary fluxes 

EMEP shall in good time before the annual meetings of the Executive Body 
provide to the Executive Body calculations of sulfur budgets and also of 
transboundary fluxes and depositions of sulfur compounds for each 
previous year within the geographical scope of EMEP, utilizing 
appropriate models. In areas outside the geographical scope of EMEP, 
models appropriate to the particular circumstances of Parties therein 
shall be used. 

                              Article 6 

           National programmes, policies and strategies 

The Parties shall, within the framework of the Convention, develop 
without undue delay national programmes, policies and strategies which 
shall serve as a means of reducing sulfur emissions or their 
transboundary fluxes, by at least 30 per cent as soon as possible and at 
the latest by 1993, and shall report thereon as well as on progress 
towards achieving the goal to the Executive Body.
