Key trends and drivers in greenhouse gas emissions in the EU in 2015 and over the past 25 years

Briefing Published 01 Jun 2017 Last modified 27 Jun 2017
​This briefing summarises the main findings of the EU’s 2017 greenhouse gas (GHG) inventory submission under the United Nations Framework Convention on Climate Change (UNFCCC) and of the EEA’s analysis of GHG emission trends in the EU between 1990 and 2015. It is underpinned by a more in-depth EEA report analysing the major factors behind changes in GHG emissions in the EU: Analysis of key trends and drivers in greenhouse gas emissions in the EU between 1990 and 2015.
Key trends and drivers in greenhouse gas emissions in the EU in 2015 and over the past 25 years
  • EU GHG emissions increased by 0.5 % in 2015 compared with 2014, following a 4 % decrease the previous year. This increase can be attributed mainly to road transport and the residential sector. Road transport emissions increased for the second year in a row.
  • Over a 25 year period (1990-2015), the EU reduced its GHG emissions by 24 %[1]. This decrease was a combined result of policies (e.g. more renewables and energy efficiency, and less use of coal compared to other fossil fuels), economic factors (e.g. recession and a more service-oriented economy) and climatic conditions (e.g. overall milder winters).

GHG emissions up in 2015 because of road transport and the residential sector

In 2015, total GHG emissions increased by 23 million tonnes (+ 0.5 %) compared with 2014, to reach 4 310 million tonnes of carbon dioxide equivalent (MtCO2e). It was the first increase since 2010 and although modest, it followed a 4 % decrease in 2014 and came alongside an increase in GDP of 2.2 %, the largest GDP increase since the economic crisis began in the second half of 2008. Overall, in 2015, GHG emissions and economic growth continued their two-decade long, uninterrupted decoupling trend.

Spain, Italy and the Netherlands accounted for the largest increases in GHG emissions, in absolute terms, in the EU in 2015, while a very large decrease took place in the United Kingdom (Figure 1).

Total energy consumption (and energy-related emissions) increased overall in 2015, driven by an increased use of natural gas and crude oil. But the reduced use of solid fuels (for the third consecutive year) and the sustained increase in the use of renewables, particularly biomass, wind and solar, offset otherwise higher emissions. Electricity production from hydro and nuclear energy declined in 2015.

The increase in energy use and related emissions was triggered by a higher demand for heat from the residential and commercial sectors, as a result of slightly-colder winter conditions in Europe during 2015 compared with 2014. The year 2014 was the hottest year on record in Europe and the second hottest worldwide, whereas 2015 was the hottest year worldwide and the second hottest in Europe.

Road transport demand, and subsequently road transport GHG emissions, increased for the second year in a row, confirming the upward trend in emissions that started in 2014. In 2015, these emissions accounted for 20 % of total GHG emissions, up 1.6 % over 2014. This increase can be attributed mainly to higher diesel consumption in passenger cars, but also in heavy- and light-duty vehicles.

Neither road transportation nor the residential sectors are covered by the EU emissions trading system (ETS), which explains why overall net emissions increased in spite of the reduction in EU ETS emissions the same year. In fact, ETS emissions for stationary installations decreased by 0.7 %, whereas emissions from the non-trading sectors increased by 1.4 % in 2015.

Despite this increase in emissions in 2015, the carbon intensity of the EU energy system decreased, because of the increased shares of renewables and gas relative to coal in the fuel mix. The EU economy was also less energy intensive overall, as demonstrated by the fact that total energy consumption increased less rapidly than gross domestic product (GDP). The improvement in energy intensity was largely driven by lower transformation losses and better energy efficiency.

Perhaps one of the most positive developments in 2015 was the decrease in emissions from refrigeration and air conditioning, which has halted the almost exponential increase of hydrofluorocarbon (HFC) emissions since 1990. Spain was mostly responsible for this decrease.

EU reduces GHG emissions by 24 % in 25 years

Total GHG emissions in the EU (excluding LULUCF) decreased by 1 337 million tonnes between 1990 and 2015 (an overall reduction of 23.7 %). They reached their lowest level during this period in 2014 before increasing slightly in 2015 to 4 308 MtCO2e. The reduction amounts to 22.1 % compared with 1990 if emissions from international aviation are included. There has been a progressive decoupling of GDP and GHG emissions since 1990, with an increase in GDP of about 50 % alongside a decrease in emissions of almost 24 % over the period.

The reduction in greenhouse gas emissions over these 25 years can be put down to a variety of factors, including:

  • the effects of a number of policies (both EU and country-specific), including key agricultural and environmental policies in the 1990s, and climate and energy policies in the 2000s. These include, among others:
    • the growing use of energy from renewable sources, in particular the strong increase in the use of biomass for energy purposes,
    • the use of less carbon intensive fossil fuels (e.g. switch from coal to gas), and
    • improvements in energy efficiency;
  • structural changes in the economy;
  • the effects of economic recession;
  • the milder winters experienced in Europe on average since 1990, which has reduced the demand for energy to heat households.

GHG emissions decreased in the majority of sectors between 1990 and 2015, with the notable exception of transport, and refrigeration and air conditioning (Figure 2). The largest emission reductions were related to energy use in sectors such as manufacturing industries and construction, electricity and heat production, and residential combustion. The largest decrease in emissions in relative terms was in waste management (through reduced and better controlled landfilling).

Almost all EU Member States reduced their emissions compared with 1990 and thus contributed to the overall positive EU performance (Figure 3). The United Kingdom and Germany accounted for about 48 % of the total net reduction in the EU over the past 25 years. The main reasons for the favourable trend in Germany were an increase in the efficiency of power and heating plants, and the economic restructuring of the five new Länder after the German reunification, particularly in the iron and steel sector. Lower GHG emissions in the United Kingdom were primarily the result of liberalising energy markets and the subsequent fuel switch from oil and coal to gas in electricity production.

Footnote

[1] The figures included in this briefing exclude emissions from international aviation. Total GHG emissions reported under the UNFCCC, exclude net emissions from the land use and forestry sectors, as well as emissions from international aviation and shipping. However, the EU GHG emission targets include emissions from international aviation. If these are taken into account, the GHG reduction compared to 1990 is 22 %.

Global and European temperature Global and European temperature According to three different observational records of global average annual near-surface (land and ocean) temperature, the last decade (2006–2015) was 0.83 to 0.89 °C warmer than the pre-industrial average, which makes it the warmest decade on record. Of the 16 warmest years on record, 15 have occurred since 2000. The year 2015 was the warmest on record, around 1 °C warmer than the pre-industrial level, followed by 2014. The average annual temperature for the European land area for the last decade (2006–2015) was around 1.5 °C above the pre-industrial level, which makes it the warmest decade on record. Moreover, 2014 and 2015 were jointly the warmest years in Europe since instrumental records began. Climate models project further increases in global average temperature over the 21st century (for the period 2081–2100 relative to 1986–2005) of between 0.3 and 1.7 °C for the lowest emissions scenario (RCP2.6) and between 2.6 and 4.8 °C for the highest emissions scenario (RCP8.5). All UNFCCC member countries have agreed on the long-term goal of keeping the increase in global average temperature to well below 2 °C compared with pre-industrial levels and have agreed to aim to limit the increase to 1.5 °C. For the three highest of the four RCPs, global average temperature increase is projected to exceed 2 °C compared with pre-industrial levels by 2050. Annual average land temperature over Europe is projected to increase by the end of this century (2071–2100 relative to 1971–2000) in the range of 1 to 4.5 °C under RCP4.5 and 2.5 to 5.5 °C under RCP8.5, which is more than the projected global average increase. The strongest warming is projected across north-eastern Europe and Scandinavia in winter and southern Europe in summer. The number of warm days (those exceeding the 90th percentile threshold of a baseline period) have almost doubled since 1960 across the European land area. Europe has experienced several extreme heat waves since 2000 (2003, 2006, 2007, 2010, 2014 and 2015). Under a high emissions scenario (RCP8.5), very extreme heat waves as strong as these or even stronger are projected to occur as often as every two years in the second half of the 21st century. The impacts will be particularly strong in southern Europe.
