Description of work and role of participants
Task 8.1: Mitigation and policy options (lead: 19,14,2,15)
The task will distinguish between short term options and measures, that can be implemented more or less until ca.
2010 (e.g. traffic restrictions, city toll), medium term measures, that include changes of infrastructure and can thus
be implemented in 2020 and long term options to be used after 2030 – time horizon until 2050.
For the first two categories possible additional options and measures will be systematically collected, analyzed and
assessed – additional means additional to those measures that are already used in the baseline scenario. For this
purpose, existing evaluations of measures will be reviewed, such as the extensive set of recommendations by the
INTEGAIRE network and forthcoming evaluations of plans and programmes reported by EU Member States under
the AQ daughter directives. The assessment will include the estimation of potential/effect (emission reduction
achieved) and the costs. As well technical measures (changing emissions factors e.g. by using filters) as nontechnical
measures (that influence the behaviour resp. decisions) are covered. For non-technical measures, changes
in utility have to be included in the costs. Other advantages and disadvantages will be qualitatively stated. The
assessment will mainly be based on existing studies resp. analyses of measures.
The measures are then ranked according to their estimated efficiency: as measures often change emissions of more
than one pollutant and as a comparison across different impacts should be made, the estimation of the effectiveness
(costs per t of pollutant reduced) is not sufficient; thus the reduced emissions are weighted with the marginal
monetized avoided damages, results are the costs per € of damage avoided. Based on this efficiency criterion
measures are then combined to bundles of measures or ‘strategies’.
For these strategies, the changes in emissions (i.e. activities or emission factors) compared to the parameter values
in the baseline scenario are estimated and reported to WP 1, where the emission tools are used to estimate the
emissions, which are then delivered to WP 7 as input for the integrated assessment tools.
Costs and difference in impacts compared to the base line scenario will then be used to assess the cost benefit ratio
and the net present value of advantages of the strategies. Based on this, the options that policy has to initialize the
realization of the strategies will be analyzed and assessed. From the result, policy recommendations will be
developed.
In addition long term mitigation and policy options (for 2030 to 2050) including structural changes, e.g. shift of
industrial activities or living places to other areas are analysed; urban planning projects methodologies are used to
develop scenarios of possible evolutions of megacities (Paris, London, Rhine-Ruhr, Po Valley, Mexico City), i.e. a
qualitative description of the possible development of settlement structure and infrastructure and development of
assumptions about the effect of these scenarios on transport, energy supply and emissions of air pollutants.
Task 8.2: Interaction with megacities administration and other stakeholders (lead: 14, 19, 16, 4, 18, 2, 6)
Aims: to inform stakeholders about the aims and intermediate results of the project, to discuss results, to collect
available information.
Contact has been established and will be maintained with the following stakeholders:
The administrations of the megacities/agglomerations Paris, London, Rhine-Ruhr, Po Valley, Mexico-City; several
DGs of the European Commission; and the EUROCITIES network.
The contact is first established via individual visits of the contact partners, that are allocated to each stake holder
(Paris: 6, London: 18, Po Valley: 4, Rhine-Ruhr: 19, Mexico-City: 2, EUROCITIES: 14, EC: 14/19). In these visits,
the project is presented and information about emission data (together with WP1), about scenarios on the future
development of the cities and their emissions, about analyses of the potential and costs of abatement measures,
about experience with air pollution and GHG reduction strategies already implemented and planned and about plans
about future abatement strategies and their effect is systematically collected. The information is translated,
transformed into a given structure and provided to Task 8.1.
