Objective:
At the scale of 50 years, we postulate that emissions and the activities, processes, and infrastructure associated with them, are pliant – that is, they are adaptable. Rather than trying to predict how emissions will change in the future and what impact they will have on future air quality (and hoping that the impact is beneficial), we propose a method in which we define a desirable air quality state and then derive the emissions and activity profiles required to achieve it. Our objectives then are threefold: 1) to develop and apply at the regional community scale a reasonable method for defining one or more desirable future air quality states; 2) to develop and demonstrate an “inverse” approach that utilizes the future desired air quality to derive the emissions, activities, processes, and infrastructure that are needed to achieve the desired future; and 3) to identify the types and amounts of land use modifications, technology advancements, and other changes that will be required to transform or morph the present emissions scenario into the future desired emissions scenario.
Progress Summary:
During this third project year, refinements were added to the economic based approach for defining the desirable future air quality state enabling more variations on the original objective. While it is maintained that none of these proposed future air quality states are necessarily representative of the actual future population’s desire, collectively they may suggest a bounded range of consensus. As these scenarios are propagated through the inverse model to derive the necessary emissions profiles, they will provide us some indication of the sensitivity of the approach to the input future state. Ensuring that the inverse model itself was correctly functioning and that it was developed and deployed in such a way so as to be sufficiently flexible for exploring a range of different air quality objectives was the primary focus of the project team over the last year. Major development and evaluation is now complete. A set of future air quality scenarios have been identified for production runs which will kick off the third and final phase of the project. In preparation for the final phase of the project, we conducted analyses that compared urban form metrics to emissions at the highest resolution available in the air quality model. This sets the stage for being able to connect future model derived emissions with real, tangible land use and transportation characteristics. Results and derivative works from Phases I and II were presented at numerous conferences and symposia, and especially directed towards stakeholders in Georgia.
Future Activities:
With the major development work of Phases I and II now complete, the final project year will be dedicated to completing the third objective in which emissions are related to specific types of neighborhoods and communities, and the amenities and characteristics inherent to them that fit within the constraints of those emissions. As noted in this report, the chief challenge at this point is finding common ground between the emissions estimated by the inverse air quality modeling and the SMARTRAQ database. Once this link is established, it is relatively straight forward to identify the physical characteristics that must be present in order that the desired air quality is realized. Further, with that final link established, we can move into a “production” mode and contemplate outcomes based on the several different future air quality scenarios described in this report. Finally, we will continue the process of communicating results and methods to others in the community.
