EDGAR - What's new

The EDGAR v4.3.2_VOC_SPEC global speciated NMVOC emissions dataset.

Non-methane volatile organic compounds (NMVOC) include a large number of chemical species differing for their chemical composition and properties. The disaggregation of total NMVOC emissions into species is thus required to better model ozone and secondary organic aerosols formation. Region- and sector-specific NMVOC speciation profiles are here developed and applied to the EDGARv4.3.2 database covering the years 1970-2012, with the same sector resolution as the total NMVOC. The complete documentation on the speciation profiles and on the methodology used can be found in Huang et al. (2017).

Trends in Global CO2 Emissions.
by J.G.J. Olivier, G. Janssens-Maenhout, M. Muntean,. J.H.A.W. Peters, November 2016

2015, the year of the landmark Paris Agreement was remarkable. Not only was 2015 the hottest year since records began in 1880, but top emitter China started to curb carbon dioxide (CO2) emissions. As a result, global CO2 emissions from fossil fuel combustion and cement production and other processes decreased in 2015 by 0.1% compared to 2014. China (with 29% share in global total) and the United States (with 14% share) gave an example by effectively reducing their CO2 emissions by 0.7% and 2.6%, respectively, in 2015 compared to 2014. Also emissions in the Russian Federation (5% share) and Japan (3.5% share) decreased by 3.4% and 2.2%, respectively. However, the European Union (EU-28) (10% share) and India (7% share) report increases of 1.3% and 5.1%, respectively. Taking into account the uncertainty in the trend we conclude that in 2015 global CO2 emissions for these sources have stalled. Since global population growth is 1.2% per year, stalling of global emissions means per definition a 1.2% decrease in global per capita CO2 emissions from 5.0 ton CO2/cap in 2014 to 4.9 ton CO2/cap in 2015. On a global scale, the slowdown in emissions since 2012 has lasted for four years now and also reflects structural changes in the global economy, such as improvements in energy efficiency and in the energy mix in major emitting countries, as anticipated in previous CO2 reports of Olivier et al. (2015, 2014). However, further mitigation of fossil-fuel use is called for to achieve the large absolute decreases in global greenhouse gas emissions that are necessary to meet the Paris Agreement's goal to keep global warming to well below 2degC. The reductions needed to meet this target are still achievable through further deployment of mitigation measures, provided that the deployment is implemented both at large scale and fast. The Clean Energy Package, proposed by the European Commission on 30th November 2016 is a good example in this direction.

The Covenant of Mayors: GHG Emissions Achievements and Projections
by A. Kona, G. Melica, A. Iancu, B. Koffi, P. Zancanella, S. Rivas Calvete, P. Bertoldi, G. Janssens-Maenhout, F. Monforti-Ferrario, November 2016
presented at the Energy for cities event at COP22 by P. Bertoldi (European Commission, JRC)

This JRC report assesses the success of the 8-yr old Covenant of Mayors initiative. After the adoption of the EU Climate and Energy Package (updated under COM/2015/080), the European Commission launched in 2008 the Covenant of Mayors initiative as a way to endorse and support the efforts deployed by local authorities in the implementation of sustainable energy policies. The Energy DG of the European Commission extended end last year the mandate to cover not only mitigation but also adaptation and the time horizon to 2030 (in line with EU’s 2030 climate and energy package) and renamed the initiative as the Covenant of Mayors for Climate and Energy. In September 2016 already 213 million citizens are covered by a city that adhered to the initiative, which proves the successful outreach to local authorities at various levels (from municipalities to regions and provinces), nonprofit organizations and networks. The minimum mitigation target of 20% greenhouse gases emission reduction by 2020 was, in September 2016, already overcommitted with 7% point by 5910 signatories (representing 204.01 million citizens) that set an overall reduction target of 27%.

Also the 1 Gigaton Coalition lists CoM as one of the success stories in their report "Renewable energy and energy efficiency in developing countries: contributions to reducing global emissions", released on 3 November 2016. Followup is foreseen with a methodological workshop at COP22 on 17th November.

Towards a European Operational Observing System to Monitor Fossil CO2 emissions, by P. Ciais, D. Crisp, H.A.C. Denier van der Gon, R. Engelen, M. Heimann, G. Janssens-Maenhout, P. Rayner, M. Scholze, reviewed by P. Bergamaschi, M. Dowell, G. Broquet, F. Chevallier, B. Pinty, H. Zunker, October 2015
presented at the EarthInfo event of UNFCCC at COP22 by B. Pinty (European Commission, JRC - DG GROW)

This European Commission (EC, DG GROW - JRC) report spells out the ingredients for a European CO2 Space programme under the Copernicus framework. It provides the roadmap for a European integrated observation system dedicated to the monitoring of fossil CO2 emissions using independent atmospheric observations. The CO2 monitoring system comprises: (1) atmospheric CO2 measurements obtained from dedicated space-borne sensors, complemented by in-situ networks, which together allow for the separation of fossil CO2 emissions from natural fluxes, (2) the operational provision of bottom-up fossil CO2 emission maps, at high spatial and temporal resolution, and near-real-time updates, (3) an operational data-assimilation system, which will integrate atmospheric measurements with bottom-up information into consistent and accurate estimates of fossil CO2 emissions and their trends. In followup of the identified current and future scientific and technical capacities, the EC (DG GROW/ Copernicus) established CO2 Monitoring Task Forces, with ESA (Earth Observation Programme) to advise on the pre-operational implementation of a space component and with JRC to set-up a specific European verification system with an operational data infrastructure for monitoring anthropogenic CO2 emissions. The ultimate goal for the EC is to enable an observation system to monitor global anthropogenic GHG emissions with operational and internationally coordinated capabilities likely to be available in the 2030s.

Forty years of improvements in European air quality: regional policy-industry interactions with global impacts

The EDGARv4.3.1 (Emissions Database for Global Atmospheric Research) global anthropogenic emissions inventory of gaseous (SO2, NOx, CO, non-methane volatile organic compounds and NH3) and particulate (PM10, PM2.5, black and organic carbon) air pollutants for the period 1970–2010 is used to develop retrospective air pollution emissions scenarios to quantify the roles and contributions of changes in energy consumption and efficiency, technology progress and end-of-pipe emission reduction measures and their resulting impact on health and crop yields at European and global scale. The reference EDGARv4.3.1 emissions include observed and reported changes in activity data, fuel consumption and air pollution abatement technologies over the past 4 decades, combined with Tier 1 and region-specific Tier 2 emission factors. Two further retrospective scenarios assess the interplay of policy and industry. The highest emission STAG_TECH scenario assesses the impact of the technology and end-of-pipe reduction measures in the European Union, by considering historical fuel consumption, along with a stagnation of technology with constant emission factors since 1970, and assuming no further abatement measures and improvement imposed by European emission standards. The lowest emission STAG_ENERGY scenario evaluates the impact of increased fuel consumption by considering unchanged energy consumption since the year 1970, but assuming the technological development, end-of-pipe reductions, fuel mix and energy efficiency of 2010. Our scenario analysis focuses on the three most important and most regulated sectors (power generation, manufacturing industry and road transport), which are subject to multi-pollutant European Union Air Quality regulations. Stagnation of technology and air pollution reduction measures at 1970 levels would have led to 129% (or factor 2.3) higher SO2, 71% higher NOx and 69% higher PM2.5emissions in Europe (EU27), demonstrating the large role that technology has played in reducing emissions in 2010. However, stagnation of energy consumption at 1970 levels, but with 2010 fuel mix and energy efficiency, and assuming current (year 2010) technology and emission control standards, would have lowered today's NOx emissions by ca. 38%, SO2 by 50% and PM2.5 by 12% in Europe. A reduced-form chemical transport model is applied to calculate regional and global levels of aerosol and ozone concentrations and to assess the associated impact of air quality improvements on human health and crop yield loss, showing substantial impacts of EU technologies and standards inside as well as outside Europe. We assess that the interplay of policy and technological advance in Europe had substantial benefits in Europe, but also led to an important improvement of particulate matter air quality in other parts of the world.
