Past and Future non-CO2 emissions for IPCC AR5

Résumé

We will discuss the recently created emission datasets that will be used in the AR5 (Assessment Report 5) of the IPCC (Intergovernmental Panel on Climate Change) report under preparation. These emissions will be used as boundary conditions for the air quality simulations from 1850 to about 2030, as well as to calculate the concentrations which will be used in the coupled earth-system models used in the climate simulations done over the 1850-2300 period. Emissions of gaseous and particulate species (i.e. aerosols, aerosol precursors, ozone precursors and ozone-destroying agents) from anthropogenic activities and biomass burning have been defined over the full period, using the 2000 dataset for harmonization of the past and current 1850-2000 emissions with the future emissions determined by the Integrated Assessment Models (IAMs). We will describe the methodology used to create the historical emissions using a variety of existing datasets. An evaluation and harmonization across different emission datasets and different periods has been achieved. Based on this evaluation, one dataset was selected for each emission sector for each compound. A methodology was defined in order to harmonize these different datasets over different regions, and ensure a good consistency of the datasets over the full period. A gridding methodology was also defined, and emissions at a 0.5x0.5 resolution are provided. Future emissions are generated by integrated assessment models. These projections are calibrated to the consensus year 2000 inventory and are consistent with the four underlying 21st century "representative concentration pathways" (RCPs) and their associated economic, energy, and land-use changes. We will also present the various ways such datasets are made available to the community.
