EU legislation has led to improvements in air quality, with the percentage of urban citizens exposed to pollutant levels above standards set to protect human health falling between 2000 and 2019. However, poor air quality remains a problem: in 2019, 21% of citizens were exposed to O 3 and 10% to PM 10 levels above EU standards. This is mainly because of emissions from transport and buildings, but also from agriculture and industry. Without radical changes to mobility, energy and food systems and industry, it is unlikely that air quality targets will be met in the near future.
Historical greenhouse gas emissions from the EU buildings sector show a decreasing trend since 2005. This is the result of the implementation of higher standards for new buildings, measures to increase energy efficiency in existing buildings (e.g. through changing of heating systems, thermal insulation and more efficient heating systems), measures to decarbonise the electricity sector but also warmer temperatures. These reductions were partly offset by the increase in dwellings and by a larger average floor area in buildings. The trend in reducing emissions is expected to continue in the future, but a very strong increase in the renovation rate is needed to meet the overall EU 2030 emissions target.
Through its land use, land use change and forestry (LULUCF) activities, the EU currently removes a net total of 249 Mt CO 2 e from the atmosphere every year, equivalent to 7% of its annual greenhouse gas emissions. The sector will play a crucial role in helping the EU achieve net zero emissions by 2050. Doing so will require reversing the current decreasing trend of the EU's carbon sink . According to national projections from EU Member States, current measures in place will not be sufficient to achieve this, with an average removal of 200 Mt CO 2 e per year in 2030. However, implementing the national measures currently at planning stage could increase the current EU carbon sink by 3%.
Greenhouse gas emissions from the agriculture sector are covered by national annual emission targets. Between 2005 and 2019, the EU’s agriculture emissions remained stable. Current national projections only foresee a modest decline of 2% by 2030, compared with 2005 levels, and a 5% reduction with the implementation of currently planned measures. This projected progress remains largely insufficient and highlights the need for further action if Member States are to reach their binding annual targets and the EU its climate neutrality goal by 2050.
The Covid-19 pandemic had a profound impact on energy consumption in the European Union. In 2020, the EU’s primary energy consumption (for all energy uses) experienced a historical drop following 2 years of moderate reductions. Final energy consumption (by end users) also saw a significant decrease, albeit less pronounced. This contributed to the EU meeting their 2020 energy efficiency targets for both primary and final energy consumption. A rebound must be avoided; and long-term reductions remain necessary to achieve the EU’s energy and climate objectives for 2030 and 2050.
With a 21.3% share of energy consumed from renewable sources in 2020, the EU has reached its headline target (20%) for 2020, according to EEA early estimates. This success builds upon years of consistent work by all Member States, even if national progress is uneven. The exceptional circumstances of 2020, marked by disruptions in all economic sectors due to the pandemic, have facilitated meeting the renewable energy target by lowering total energy consumption. An unprecedented transformation in the energy system will still be necessary to meet the 32% renewable energy target set for 2030.
In 2019, the EU was not on track to meet its target to reduce the greenhouse gas emission intensity of fuels sold for road transport to 6% below 2010 levels by 2020. Between 2010 and 2019, emission intensity decreased by 4.3%, mostly due to the increased use of biofuels. Finland and Sweden are the only Member States whose emission intensities decreased by more than 6%, with the Netherlands reporting a 5.8% reduction in 2019. If the indirect land use change (ILUC) effects of biofuel production are considered, the emission intensity of fuels sold in the EU also decreased between 2018 and 2019, due to the limited substitution of oil crops as feedstocks by sugars.
The share of energy from renewable sources used for transport in the EU increased from under 2% in 2005 to almost 9% in 2019. Preliminary EEA data indicate that in 2020, this increased further to 10.1%. This suggests that collectively the EU countries reached the 10% target for share of energy from renewable sources in all forms of transport. However, EEA preliminary estimates show that this target was actually achieved by less than half of EU Member States.
Greenhouse gas emissions in the EU decreased by 31% between 1990 and 2020 — exceeding the EU’s 2020 target by 11 percentage points. This overshoot was propelled by steep emission cuts in 2019 and 2020. While the cut in 2019 was strongly driven by fossil fuel price effects and policy measures, the decline in 2020 was additionally related to the Covid-19 pandemic. EU greenhouse gas emissions are expected to further decline until 2030. Member States have not yet realigned their ambitions to the new net 55% reduction target for 2030, and the further implementation of impactful policies and measures will be important to bring the new 2030 target within reach.
EU greenhouse gas emissions covered by national reduction targets decreased by 15% between 2005 and 2020, which is significantly more than the 10% reduction foreseen in the Effort Sharing Decision (ESD). These reductions were largely driven by improvements in energy efficiency and the switch to less carbon intensive fuels, including renewable energy. Preliminary emissions data for 2020 show that 21 EU Member States are expected to be below their national emission targets for that year. Six Member States are expected to have emissions above their 2020 target levels, despite the effects of the measures to address the pandemic.
Greenhouse gas emissions from the EU’s transport sector increased steadily between 2013 and 2019, a trend that diverges significantly from those in other sectors during that period. Preliminary estimates for 2020 indicate a substantial drop in transport emissions, due to decreased activity during the Covid-19 pandemic. It is anticipated that transport emissions will rebound after 2020. National projections compiled by the EEA indicate that even with measures currently planned in the Member States, domestic transport emissions will only drop below their 1990 level in 2029. International transport emissions (aviation and maritime) are projected to continue increasing.
The greenhouse gas emission intensity of power generation in the EU has been continuously decreasing over the last three decades: generating 1 kilowatt hour in 2020 emitted, on average, half as much CO 2 as in 1990. Policies have been playing an important role in driving this shift towards less carbon-intensive energy sources, in particular those addressing climate change, renewable energy supply and efficient energy use, and industrial emissions. The Covid-19 pandemic hardly affected electricity use in 2020, but the continued growth of renewable electricity caused a further drop in the greenhouse gas emission intensity of electricity generation.
Heavy metals accumulate in ecosystems and damage human health. In line with the EU’s commitments under the Air Convention, specific legislation led to reductions in emissions of heavy metals across Europe from 1990 levels. Between 2005 and 2019, emissions have continued to decline, with lead emissions decreasing by 44%, mercury emissions by 45% and cadmium emissions by 33% across the EU-27 Member States. In 2019, Germany, Italy and Poland contributed most to heavy metal emissions in the EU.
The air pollutants ammonia (NH 3 ), non-methane volatile organic compounds (NMVOCs), nitrogen oxides (NO X ), fine particulate matter (PM) and sulphur oxides (SO X ) damage human health and the environment, so reducing their emissions is a priority of both EU and international air quality legislation. Since 2005, emissions of all five pollutants have declined and, by 2012, the emission ceilings set for NH 3 , NMVOCs, NO X and SO X had been met. However, based on progress so far, it is clear that more effort, particularly in the transport, energy and agriculture sectors, is essential if the EU is to fulfil longer term reduction commitments.
In 2020, the EU continued to actively phase out ozone-depleting substances (ODS), in line with its commitment under the Montreal Protocol. Data for 2020 show that consumption of ODS in the EU remained negative (-2,023 metric tonnes), meaning that more substances were destroyed or exported than were produced or imported. The EU´s consumption of these substances has been negative since 2012. For more information and data reported by companies under the Ozone Regulation, see the online ODS data viewer .
The Water Framework Directive aims to achieve good status for all rivers, lakes and transitional and coastal waters in the EU. Achieving good ecological status for surface waters is critical to this. According to countries’ second river basin management plans, good ecological status had been achieved for around 40% of surface waters (rivers, lakes and transitional and coastal waters) by 2015. However, these plans show only limited improvement in ecological status since the first plans were published in 2009, with ecological status remaining similar for most water bodies.
Ocean surface pH declined from 8.2 to below 8.1 over the industrial era as a result of an increase in atmospheric CO 2 concentrations. This decline corresponds to an increase in oceanic acidity of about 30%. Reductions in surface water pH are observed across the global ocean. Ocean acidification has impacts on marine organisms and has already affected the deep ocean, particularly at high latitudes. Models project further ocean acidification worldwide. The target under United Nations Sustainable Development Goal 14.3 is to minimise the impacts of this by 2030.
The waste recycling rate — the proportion of waste generated that is recycled — is growing in the EU-27, indicating progress towards using more waste as a resource and achieving a circular economy. The rate of progress is slowing down, however, with little improvement over the past 5 years. Achieving a more circular economy requires a faster rate of progress, as the amount of waste recycled is still less than half of total waste generated. Specific waste streams show varying recycling rates, ranging from 66% for packaging waste to 39% for electrical and electronic waste.
All European seas have warmed considerably since 1870, particularly since the late 1970s. During the period for which comprehensive data are available (1981-2018), sea surface temperature increased by between 0.2 °C, in the North Atlantic, and 0.5 °C, in the Black Sea, per decade. This increase is projected to continue, although more slowly than that of air temperature over land. The frequency and magnitude of marine heatwaves has also increased significantly globally and in European seas and is projected to continue, with increasing impacts on ecosystems and climate expected.
Climate change has increased forest fire risk across Europe. Even so, the burnt area of the Mediterranean region has decreased slightly since 1980, indicating that fire control efforts have been effective. However, in recent years, forest fires have affected regions in central and northern Europe not typically prone to fires, and, in 2018, more countries suffered large fires than ever before, coinciding with record droughts and heatwaves. An expansion of fire-prone areas and longer fire seasons are projected in most European regions, so additional adaptation measures are needed.
