Adaptation challenges and opportunities for the European energy system

This report explores the historical trends, most recent progress and projected future progress on climate change mitigation through reduced GHG emissions, renewable energy gains and improved energy efficiency. It builds upon data reported by the EU-27 Member States, five EEA member countries and nine Contracting Parties of the Energy Community.

Regional climate change and adaptation — The Alps facing the challenge of changing water resources

Drawing on the most recent knowledge of climate change impacts in the Alps and experiences across the region, this report analyses the risks that climate change presents to the region's water supply and quality, identifying needs, constraints, opportunities, policy levers and options for adaptation. It extracts policy guidance on adaptation practice and aims to assist regional and local stakeholders in developing robust adaptation strategies. The focus of the report is on water resources and related adaptation, rather than water-related extreme events like floods, avalanches, landslides or mudflows, which are already well covered by existing studies of climate change impacts in the Alps.

Sectoral shares of acidifying pollutants (SO2, NOx, NH3; energy and non-energy components) of total emissions, EEA-32. Values within the segments indicate the level of emissions (kt) emitted from each sector.

The emissions of acidifying pollutants (sulphur dioxide SO2, nitrogen oxides NOx and ammonia NH3) are each weighted by an acid equivalency factor prior to aggregation to represent their respective acidification potentials. The acid equivalency factors are given by: w(SO2) = 2/64 acid eq/g = 31.25 acid eq/kg, w(NOx) = 1/46 acid eq/g = 21.74 acid eq/kg and w(NH3) = 1/17 acid eq/g = 58.82 acid eq/kg.

Sectoral shares of primary and secondary particulate matter in total emissions, EEA-32

The graph includes the combined emissions of primary PM10 particles (particulate matter with a diameter of 10 μm or less, emitted directly into the atmosphere) and secondary particulate-forming pollutants (the fraction of sulphur dioxide, SO2, nitrogen oxides NOx and ammonia NH3 which, as a result of photo-chemical reactions in the atmosphere, transform into particulate matter with a diameter of 10μm or less). Emissions of the secondary particulate precursor species are weighted by a particle formation factor prior to aggregation: primary PM10 = 1, SO2 = 0.54, NOx = 0.88, and (NH3) = 0.64.

Sectoral shares of tropospheric ozone precursors (energy and non-energy components) in total emissions, EU-27.

The emissions of ozone precursors (NOx, NMVOC, CO and CH4) are each weighted by an ozone formation factor prior to aggregation to represent their respective ozone forming potentials. The relative impact of the combined contribution of NOx, NMVOC, CO and CH4 to ozone formation can be assessed based on their tropospheric ozone forming potentials (TOFP): nitrogen oxides 1.22, non-methane volatile organic compounds 1.0, carbon monoxide 0.11 and methane 0.014.

Selected oil and gas reserves

The bars show proved oil and natural gas reserves by country. Only countries with more than 20 billion barrels of oil are shown (top maps). Only countries with more than 3 billion cubic metres are shown (bottom maps).
