On the CH4 and N2O emission inventory compiled by EDGAR and improved with the EPRTR data for the INGOS project

This report documents the EDGAR INGOS emission inventory for CH4 and N2O, as publicly made available on: http://edgar.jrc.ec.europa.eu/ingos/index.php?SECURE=123. The EDGAR INGOS CH4 and N2O emission inventory provides bottom‐up estimates of global anthropogenic CH4 and N2O emissions for the period 2000‐2010. The EDGAR InGOS product is an update of the EDGARv4.2FT2010 inventory, taking into account emissions reported as point sources by facilities under the European Pollutant Release and Transfer Register (EPRTR) for (1) power plants (N2O), (2) oil refineries (CH4 and N2O), (3) coal mining (CH4), (4) production of oil and gas (CH4), (5) chemicals production (inorganic, nitro‐fertilizers and other bulk chemicals) (N2O), industrial process and product use (N2O), (6) solid waste ‐ landfills (CH4), (7) industrial wastewater treatment (CH4 and N2O). In a first step gridmaps have been improved for the European region taking into account the geospatial data of the E‐PRTR database. In addition, for the last 4 years an option is given to select inventories solely based on officially reported emission data (for the categories covered by E‐PRTR), gapfilled with EDGARv4.2FT2010 for non‐reporting countries.JRC.H.2-Air and Climat

Effects of business-as-usual anthropogenic emissions on air quality.

The atmospheric chemistry general circulation model EMAC has been used to estimate the impact of anthropogenic emission changes on global and regional air quality in recent and future years (2005, 2010, 2025 and 2050). The emission scenario assumes that population and economic growth largely determine energy and food consumption and consequent pollution sources with the current technologies ("business as usual"). This scenario is chosen to show the effects of not implementing legislation to prevent additional climate change and growing air pollution, other than what is in place for the base year 2005, representing a pessimistic (but feasible) future. By comparing with recent observations, it is shown that the model reproduces the main features of regional air pollution distributions though with some imprecisions inherent to the coarse horizontal resolution (~100 km) and simplified bottom-up emission input. To identify possible future hot spots of poor air quality, a multi pollutant index (MPI), suited for global model output, has been applied. It appears that East and South Asia and the Middle East represent such hotspots due to very high pollutant concentrations, although a general increase of MPIs is observed in all populated regions in the Northern Hemisphere. In East Asia a range of pollutant gases and fine particulate matter (PM2.5) is projected to reach very high levels from 2005 onward, while in South Asia air pollution, including ozone, will grow rapidly towards the middle of the century. Around the Arabian Gulf, where natural PM2.5 concentrations are already high (desert dust), ozone levels are expected to increase strongly. The per capita MPI (PCMPI), which combines demographic and pollutants concentrations projections, shows that a rapidly increasing number of people worldwide will experience reduced air quality during the first half of the 21st century. Following the business as usual scenario, it is projected that air quality for the global average citizen in 2050 would be almost comparable to that for the average citizen in the East Asia in the year 2005, which underscores the need to pursue emission reductions.JRC.H.2-Air and Climat

Climate and Air Quality Impacts of Combined Climate Change and Air Pollution Policy Scenarios

This report describes an assessment of the co-benefits for air pollution of recently developed climate mitigation scenarios that inform the European Union policy making. The climate mitigation scenarios were obtained with the POLES equilibrium model for a business-as-usual and greenhouse gas reduction case. In the present work, these scenarios were expanded to air pollution emissions. The resulting set of global -spatially and sector disaggregated- air pollution emissions were evaluated with the global chemistry transport model TM5, to calculate levels of particulate matter and ozone. Subsequently, air pollution impacts on human health, ecosystems and climate were evaluated. The resulting set of four scenarios thus reflect various combinations of worldwide air pollution and climate policies: BAU (¿no further climate and air pollution policies since the 2000 base-year¿); CARB (¿climate policy only¿), BAP (¿no further climate policy, but progressive air pollution policies, to address worldwide increasing levels of air pollution) and CAP (¿combination of ambitious climate and air pollution policies¿). The implementation of a global climate policy (CARB) has substantial co-benefits for reducing air pollutant emissions. Compared to BAU, in 2050 global emissions of SO2 are reduced by ca. 75 %, NOx by 55 %, CO (40 %) and other pollutants VOC, OC and BC) about 25% %. These emission reductions result from cleaner technologies and decreased fuel demand, and correspond to a CO2 emission reduction of more than 60 %. Advanced air pollution abatement technologies can obtain similar air pollutant reductions ranging between 35 % (NOx), 45 % (OC, BC), 60 % (SO2) and 70% (CO), however in this case the CO2 emissions reach unabated levels of 55 Pg CO2/yr. The combined air pollution and climate policy case (CAP) further reduces BAP air pollution emissions by 10-30 %. Noticeable are the decreases of methane emissions by ca. 60 %, which have important impacts on ozone air quality and climate. The environmental benefits of the emission reductions are substantial. In 2050, average global life expectancy increases by 3.2 months/person for BAP (compared to BAU) and further increases by 3.7 to 6.9 months/person if additionally climate policies are introduced (CAP). Compared to 2000, only the CAP scenario leads to global improvement of life-expectancy (by about 3 months/person), while all other scenarios lead to higher particulate concentration and lower life expectancies, mainly driven by pollution developments in South and East Asia. These improvements in CAP are due to decreasing concentrations of primary (OC, BC) and secondary (SO4, NO3) aerosol. This work shows that combining air pollution and climate policies is in some regions the only way to stabilize or decrease the levels of air pollution and reducing impacts on human health. The global average life expectancy, however, masks large regional differences: e.g. current and future levels of air pollution in Asia are much larger than in Europe or the United States. Crop losses due to ozone are reduced by 4.7 % by implementing progressive air pollution policies, and could be reduced by another 2 %, by introducing additional climate policies. Climate policies target at limiting long-term (2100) climate change. On the intermediate time-scales (2030-2050), however, there might be important trade-offs to be considered in climate and air pollution policies, since reducing particulate matter and precursor (especially sulfur) emissions, are likely to lead to a net positive radiative forcing and a warming of climate. Since reductions of particulate matter and ozone are necessary to protect human health and vegetation, combined air pollution and climate policies are more beneficial for both climate and air pollution than stand-alone policies. There is scope to preferentially mitigate emissions of Black Carbon and methane, which is beneficial for climate and human health.JRC.DDG.H.2-Climate chang

Copernicus and Earth observation in support of EU policies

The Copernicus programme for Earth observation represents a big investment by the EU, justified by expected returns in public governance and private business. Copernicus is user and policy driven, and provides cross-domain products and services with a full free and open data policy and where possible taking up new technologies and research. This study has made a survey of the extent that Copernicus is used to support policy making in the European Commission, also assessing the perspectives for increased uptake. Also other Earth observation data and information has been looked at. An extensive use of the services is observed for policies monitoring landuse, climatic and environmental conditions, and this is expected to increase further with e.g. the new Common Agricultural Policy and the Land Use, Land-Use Change and Forestry Regulation. Information of the Climate Change Service on optimal land-use targeting specific human activities, harnessing the beneficial opportunities of climate change, provides policy makers with a new set of adaptation measures. While air quality measures can be monitored by the atmosphere service, the marine service provides input to the information system for marine knowledge. The emergency service supports disaster risk reduction measures and a resilient build-up of society. Security is of increasing importance where land and water resources are at the origin of conflict and migration. Several lines of action have been identified to improve uptake: Increasing engagement within the policy Directorates-General, fostering feedback loops between the end-users and Copernicus services, Increasing communication, information and training, setting standards and guaranteeing quality controls, enabling full integration of different datasets. The Copernicus programme brings a unique opportunity to the EU for being a global player, addressing SDGs and International Conventions because of its a long-term sustained commitment and strong international dimension. No such space programme is currently available elsewhere.JRC.D.6-Knowledge for Sustainable Development and Food Securit
