Estimated impact of different factors on the reduction in emissions of NOx from public electricity and heat production between 1990 and 2008, EEA-32: The chart shows the estimated contributions of the various factors that have affected emissions from public electricity and heat production (including public thermal power stations, nuclear power stations, hydro power plants and wind plants).

CO2 emissions per m2 for space heating: The graph compares by country the level of CO2 emissions for space heating per m2 for 2 years : 1990 and 2008 (direct and indirect emissions). 1990 and 2008 data are climate corrected against each country’s long-term average climate, whereas the last series is climate corrected and scaled against the EU long-term average climate to account for temperature differences between countries.

Variation of CO2 emissions in transport (EU-27): The figure shows the variation of CO2 emissions in transport for EU-27. CO2 emissions for total transport can be split into 2 explanatory effects: an activity effet illustared by an increase in traffic of passengers and freight, CO2 savings due to the reduction in the specific emissions of vehicles per unit of traffic

Reducing speed limits on motorways: how good is it for the environment?: Lower speed limits on motorways are generally associated with road safety. But several European countries are now debating whether they also benefit the environment and, if so, how much. There is no simple way of measuring the environmental benefits of lower speed limits but several factors clearly play a key role.

Annual European Union greenhouse gas inventory 1990–2009 and inventory report 2011: This report is the annual submission of the greenhouse gas inventory of the European Union to the United Nations Framework Convention on Climate Change and the Kyoto Protocol. It presents greenhouse gas emissions between 1990 and 2009 for EU-27, EU-15, individual Member States and economic sector.

Variation of CO2 emissions from transport (EU-27): The figure shows the variation of CO2 emission from transport, EU-27 level CO2 represent around 99% of the sector’s greenhouse gas emissions. Emissions from international air transport are not included in countries’ emissions (UNFCCC methodology).

Recession and renewables cut greenhouse emissions in 2009: Greenhouse gas emissions decreased very sharply in 2009, by 7.1 % in the EU-27 and 6.9 % in the EU-15. These most recent results, compiled by the European Environment Agency (EEA), confirm estimates made by the EEA last year. This decrease was largely the result of the economic recession of 2009, but also sustained strong growth in renewable energy.

CO2 intensity of heat and electricity generation (ENER 002) - Assessment DRAFT created Aug 2011: Renewable energy contributed significantly to reduction in CO 2 intensity of the energy sector. In 2008, renewables contributed 10% in final energy consumption (see ENER28). Adding biomass to the traditional fossil fuel mix reduced the amount of CO 2 (electricity-only) emitted per KWh electricity produced by 8% in 2008. Combining fossil fuels, nuclear and renewables led to a reduction of 44% in CO 2 (electricity-only) emissions per KWh electricity produced in 2008. Between 1992 and 2008, g CO 2 emission per kWh of electricity and heat output decreased by 17% within the EU27 compared to the USA and China, where g CO 2 emissions per kWh decreased by 6% and 5% respectively. However, looking at the global trend CO 2 emissions per kWh have increased by 8%.

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.

Overall change in emissions of acidifying substances by country, 1990-2007: The graph shows the change in emissions of acidifying pollutants (sulphur dioxide SO2, nitrogen oxides NOx and ammonia NH3) 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.
