Smart Air Quality Policies for a Better Climate: A Regional Analysis.
Abstract, Goldschmidt 2013, 25-30 August 2013, Florence, Italy
Abstract
Feedbacks of climate policies on air quality (co-benefits as well as trade-offs) are now being recognized and introduced in optimization schemes for air quality policy development. However, also air quality policies can have consequences for climate. Some pollutants are contributing to warming (black carbon (BC), O3), others are cooling (SO4, NO3, organic carbon). Air quality policies are commonly designed without taking into account possible feedbacks on climate, although there is a potential for smart air quality policies that lead to a win-win situation for both climate and air quality.
In this work we evaluate the local and regional benefits of a portfolio of 16 climate-friendly, region-specific air quality measures that were identified in the frame of a recent UNEPWHO assessment [1] [2]. These measures go beyond the baseline of current legislation and provide a global potential for 0.5K temperature reduction in the coming decades. A first group of measures addresses the reduction of CH4 emissions (with associated benefits for reduced background ozone), a second group targets BC (with additional benefits for O3 for those sectors where NOx and NMVOC are co-emitted species). The portfolio of measures was designed in order to yield a maximal climate benefit worldwide, but the measures also generate clear local and regional air quality and crop production benefits which may help to incentivise the implementation. This local and regional aspect was not explored in the UNEP assessments.
In our analysis we apply a global source-receptor model with a relatively high regional resolution (global coverage with 56 regions) to each of the measures. As a result we provide a region-specific ranking of the most relevant measures in terms of local and regional benefits.
