Etymology of “Environmental Policy”
Environmental primarily refers to the ecological dimension (ecosystems), but also to the social dimension (quality of life) and to
the economic dimension (resource management).
Policy can be defined as a "course of actions or principles adopted or proposed by a government, party, business or
individual”. Thus, environmental policy focuses on problems arising from human impact on the environment, which retroacts onto human society by having a (negative) impact on human values such as good
health or the 'clean and green' environment.

The Science-Policy Loop It is a multi-step process:
• Discovery of health issues related to the use of hazardous substances or/and its release to the environment by human activities (i.e., Minamata (1953-1960), Niigata (1960-1965); Ul Hac (1956); Iraq (1956-1960) contaminated fish and seeds grain).
• Evaluation of DRIVERS acting on environment and human health / human welfare.
• Evaluation of EXPOSURE patterns for wildlife species and humans. • Evaluation of SOCIO-ECONOMIC CONSEQUENCES. • Risk assessment Scale of IMPACT (local regional global). • First policy development Policy Implementation & Geographical
Scale (i.e., country, continental, global) • Evaluation of Benefits & Costs • Review of the Policy Improve its effectiveness • Science-Policy Loop iterations

Why Anthropogenic Emissions Shall Be Regulated
- Emissions from Natural Sources/Processes cannot be regulated/controlled whereas the Anthropogenic ones can be.
- Depending on the latitude and time of the year, Natural sources release mostly Hg(0), whereas Anthropogenic sources may release all Hg species in % that depends on the source type;
- With the exception of Volcanoes, natural sources are primarily diffuse/areal sources whereas anthropogenic sources are primarily point sources different impact areas;
- Emissions from natural sources/processes are strongly dependent on meteorological conditions (time of the year) and latitudes whereas Emissions from anthropogenic sources are not;

Key Policy-Relevant Science Questions from ……
Individuals, NGOs;
Governments, regulatory bodies and business sectors at Country level;
Regulatory bodies at regional level (i.e., USA, Canada, Japan, EU, Asia, ….);
Regulatory bodies at global scale (i.e.,: UNEP Governing Council UNECE-LRTAP Task Force on HTAP OSPAR, HELCOM, Basel, Rotterdam, ACAP, MAP, ….
International Programs: GEO, GEF, UNIDO, UNEP, UNDP
UNECE-LRTAP TF HTAP Policy-Relevant Science Questions
How does the intercontinental or hemispheric transport affect deposition patterns in the NH ?
Is it possible to characterize source-receptor relationship taking into account the various mechanisms affecting its cycle (emission-chemistry-deposition-reemission) and the spatial scale (local-to-regional-to-global) ?
Are emission inventories consistent with observations ? Is the contribution of natural sources well characterized ? Is the assumption of steady-state still valid ? What about the
temporal variation of the residence time of different Hg compounds ? Besides speciated Hg measurements, what other key
measurements do we need to improve our models capabilities ? How deposition loads would change in the next 20-50 years if a
50% reduction will occur in Hg emissions ? How future changes in ozone and aerosol concentrations will
affect Hg fate and transport ?
Main steps of the “Mercury Policy Process”
2001 UNEP GC at its 21st session: need for a global assessment of mercury recognized
2003 Study “GMA Report“, prepared by UNEP presented to the GC at its 22nd session. GC agreed for further international action on mercury
2005 UNEP GC at its 23rd session called for Mercury Partnerships between governments and stakeholders: Five Partnership Areas were identified
UNEP F&T published “Dynamics of mercury pollution on regional and global scales” Springer, USA (Pirrone and Mahaffey, Eds.) 2005
UNEP GC at its 24th session: “two-track “ approach based on voluntary actions and on the path to LBI. An overarching framework for strengthening
UNEP Global Mercury Programme partnerships was developed 2007
AMAP and UNEP published “"The Global Atmospheric Mercury Assessment: Sources, Emissions and Transport” 2008
UNEP F&T published “Mercury Fate and Transport in the Global Atmosphere: Emissions, Measurements and Models” Springer, USA
(Pirrone and Mason, Eds.) 2008-2009
UNEP GC at its 25th session: agreed on an Intergovernmental Negotiating Committee (INC) to prepare a legally binding instrument
on mercury 2009
INC’s work started in 2010 and will end in 2013 2010-2013
INC’s goal is to complete the negotiations before the 27th regular session of the
GC/Global Ministerial Environment Forum in 2013

A Global Mercury Observation System able to provide continuous information on mercury concentrations and fluxes in and between the atmospheric, marine, freshwater and terrestrial ecosystems.
Validated regional and global scale atmospheric and marine models as well as socio-economic models
An International Observatory with the mandate to provide support to Policy Makers in the implementation of strategies and best practices to: Reduce the use of mercury for many industrial and commercial
applications and practices; Promote a safe storage of excess mercury at country or regional level; Support the implementation and future verification of the LBI (or Treaty
or Convention) at regional and continental scales; Run scenario analysis of different reduction strategies in order to meet
the requirements of international legislation on mercury pollution control and monitoring.
