Air pollution commitments

Despite recurring air quality problems, pollutant emissions are decreasing. However, the limits for concentrations in ambient air of NO2, particles (PM10) and ozone are still not respected everywhere in France, especially in large urban areas and when atmospheric conditions keep from dispersing pollutants or increase their formation. Thus, pollution episodes regularly occur in winter and spring in terms of particles and in summer for ozone. Due in particular to non-compliance with the concentration limit values ​​for PM10 and NO2, the European Commission has moreover launched infringement proceedings against France and the latter has been brought before the European Court of Justice for its excessively high concentrations of NO2 in 12 cities. However, the inventory results show pollutant emissions falling between 1990 and 2017. In particular, the emissions of ozone precursors fell sharply between 1990 and 2017 according to the latest results for 2018: -59% for NOx (including NO2), -75% for NMVOC, -74% for CO and – 20% for CH4. PM10 and PM2.5 emissions also decreased by 54% and 62% respectively over the same period. Generally speaking, reductions in emissions of this sort are detected all over Europe.

Pollutant emissions in France – where are we now ?

Emission decrease of particulate matter and acidification, eutrophication and ozone precursors

Despite recurring air quality problems, and in particular episodes of particulate matter and ozone pollution, it was observed that the emissions of particles (PM10, PM2.5, PM1) and acidification, eutrophication and ozone precursor pollutants (in particular NOx and NMVOC) have been declining since 1990. Annual emissions for France in a whole are therefore not a good indicator of the evolution of local and occasional concentrations but remain a key element in political decision-making and the implementation of reduction measures at both national and local levels.

-75% to -99,5% emission reductions

Emissions of most heavy metals (zinc, cadmium, mercury, nickel, chromium, lead) and persistent organic pollutants (PCB, PCDD-F, HCB) have decreased by more than 75% since 1990, with reductions greater than 95% (PCDD-F, Cr, Pb, HCB).

Warning: difference between emissions and concentrations

Citepa estimates pollutant emissions (total estimated quantities, at national level and on an annual basis) and not the concentrations in the ambient air (quantities measured by air volume, local). Air quality does not depend only on the emissions of primary pollutants (those estimated by Citepa), but also other phenomena, in particular meteorological: transport and dispersion by wind and rain, deposits, chemical reactions (such as the formation of secondary particles from primary pollutants in the gaseous state (NOx and NH3 in particular, VOCs) , formation of ozone from precursors favored by solar radiation and high temperatures), topography, resuspension of particles already emitted, etc. Thus the air quality at a point results from local emissions, emissions transported over more or less long distances depending on pollutants, meteorology and atmospheric chemical reactions. Air quality, assessed in terms of concentrations, is monitored by regional Approved Air Quality Surveillance Associations (AASQA).

 

Does France meet its pollutant emission targets ?

NEC-2 & PREPA Directive

NOX (2010 ceiling: NEC-1)  not met 

Period covered: 2010   |  Ceiling to be reached: 810 kt in 2010  |  Actual emissions: 1 077 kt  in 2010 (937 kt with the same method of calculating emissions as during the development of the NEC-1 Directive)

more

The 2010 NOx emission limit was not respected in 2010: emissions did not fall below this limit until 2017 (807 kt). As the ceiling was set in absolute value, it is necessary to take into account the difference in estimation method between when this ceiling was set and today’s estimate. Thus, if we estimate the NOx emissions in the same way as at the time [so-called adjusted emissions], then this ceiling was reached in 2014 (749 kt).

 

NOx (2020 ceiling: NEC-2, PREPA)  in progress 

Period covered: 2020   |  Ceiling to be reached: 710 kt NOX in 2020 (-50% compared to 2005)  |  Actual emissions: 807 kt in 2017

more

The targets defined in the NEC-2 Directive are as follows: -50% in 2020 (base 2005) and -69% from 2030 (base 2005). PREPA adds an intermediate target of -60% for the period 2025-2029. To achieve reductions in 2020, NOx emissions must drop from 807 kt in 2017 to 710 kt in 2020, i.e. decrease by 97 kt in 3 years, corresponding to an annual decrease of -32 kt/year. Since 2010, emissions have experienced an annual decrease of -39 kt/year. If this rate of decline continues, the 2020 ceiling can be reached.

 

NH3 (2010 ceiling: NEC-1)  met 

Period covered: 2010   |  Ceiling to be reached: 780 kt in 2010  |  Actual emissions: 604 kt  in 2010

more

The ceiling of 780 kt to be respected in 2010 was in fact respected from the start of the period, since emissions never exceeded the historical maximum of 664 kt in 1987. They have gradually decreased over a certain period but have stagnated around 600 kt / year since 2005.

 

NH3 (2020 ceiling: NEC-2, PREPA)  in progress 

Period covered: 2020   |  Ceiling to be reached: 581 kt NH3 en 2020 (-4% compared to 2005)  |  Actual emissions: 606 kt NH3 in 2017

more

The targets defined in the NEC-2 Directive are as follows: -4% in 2020 (base 2005) and -13% from 2030 (base 2005). PREPA adds an intermediate target of -8% for the period 2025-2029.  To reach the target in 2020, NH3 emissions must drop from 606 kt in 2017 to 581 kt in 2020, either decrease by 25 kt in 3 years, or an annual decrease of -8.3 kt/year. However, since 2005, emissions have stagnated at around 600 kt / year since 2005. Achieving the 2020 target requires a steady decline in NH3 emissions from 2017 to 2020.

 

NMVOC (2010 ceiling: NEC-1)  met 

Period covered: 2010   |  Target to be reached: 1 050 kt in 2010  |  Actual emissions: 817 kt in 2010

more

The limit of 1 050 kt to be respected in 2010 was actually respected from 2007 (with 966 kt).

 

NMVOC (2020 ceiling: NEC-2, PREPA)  already met 

Period covered: 2020   |  Target to be reached: 670 kt in 2020 (-43% compared to 2005)  |  Actual emissions: 612 kt in 2017

more

The targets defined in the NEC-2 Directive are as follows: -43% in 2020 (base 2005) and -52% from 2030 (base 2005). PREPA adds an intermediate target of -47% for the period 2025-2029. The 2020 target (670 kt) has already been reached in 2014 (661 kt). PREPA’s intermediate objective, 623 kt for 2025-2029, has also already been reached. To reach the 2030 target of 564 kt, emissions must fall further by 48 kt between 2017 and 2030, i.e. an average decrease of around 4 kt/year. In recent years, emissions have decreased from -10 kt to -30 kt/year. 

 

PM2,5 (2020 ceiling: NEC-2, PREPA)  already met 

Period covered: 2020   |  Target to be reached: 190 kt in 2020 (-27% compared to 2005)  |  Actual emissions: 164 kt in 2017

more

PM2.5 were not covered by NEC-1. The reductions defined in the NEC-2 Directive are as follows: -27% in 2020 (base 2005) and -57% from 2030 (base 2005). PREPA adds an intermediate target of -42% for the period 2025-2029.  The 2020 ceiling has already been reached: fine particle emissions must therefore not increase for the following years. This is unlikely as emissions have been falling steadily since 1990.

 

Convention on Long-Range Transboundary Air Pollution (CLRTAP)

Helsinki Protocol (SO2)  met 

Period covered: 1993  |  Reduction to be achieved: 1276 kt SO2 in 1993 (-60% compared to 1980)  |  Actual emissions: 1087 kt SO2 in 1993

more

The first sulphur Protocol, signed in Helsinki on 8 July 1985, came into force on 2 September 1987. France’s target was to reduce its emissions by 30% from 1980 to 1993. France had also undertaken to reduce its emissions by 60%, following the example of twelve States committing to emission reductions of at least 50%. The target of -30% and the voluntary target of -60% have been achieved as emissions have decreased by -66%.

 

Oslo Protocol (SO2)  met 

Period covered: 2000, 2005, 2010  |  Reduction to be achieved: 868, 770 and then 737 kt  SO2  (in 2000, 2005 and 2010)  |  Actual emissions: 626, 460 and then 278 kt (in 2000, 2005 and 2010)

more

The second sulphur Protocol, signed in Oslo on 14 June 1994, came into force on 5 August 1998. The new target for France was a further gradual reduction in emissions (868 kt in 2000, 770 kt in 2005 and 737 kt in 2010). The ceilings set have been very largely respected by France.

Since 1990, the drop in SO2 emissions in the various sectors can be explained by: the reduction in fossil energy consumption due to the implementation of the nuclear power program and the development of renewable energies; the implementation of energy saving actions; the progress made by manufacturers through the use of less sulfur-containing fuels and the improvement of the energy efficiency of installations. In addition to these reductions, various regulatory provisions on the sulfur content in fuels have been added, reinforcing the decrease observed.

 

Sofia Protocol (NOX)  not met 

Period covered: 1994, 1998  |  Reduction to be achieved: 1 881 and then 1 418 kt  (1994 and then 1998)  |  Actual emissions: 1 836 puis 1726 kt (1994 and then 1998)

more

The first target of the Protocol has been met

The NOx Protocol, signed in Sofia on 1 November 1988, came into force on 14 February 1991. France’s target was to stabilize its emissions from 1987 to 1994. The actual emissions in 1994, 1836 kt, are, to within 45 kt, below this ceiling which should not be exceeded.

Voluntary target not met

France made an additional commitment to reduce its emissions by 30% from 1980 to 1998. The actual emissions in 1998, 1726 kt, exceed this voluntary commitment by 308 kt. It was not until 2006 to reach an emission level lower than this commitment.

 

Geneva Protocol (NMVOC)  met 

Period covered: 1999 |  Reduction to be achieved: 1 756 kt  (-30% compared to 1988)  |  Actual emissions: 1 750 kt in 1999

more

The COV Protocol, signed in Geneva on 18 November 1991, came into force on 29 September 1997. Biogenic sources (natural sources) are excluded from this commitment.  France agreed to reduce its emissions by 30% from 1988 to 1999. This target was reached within 6 kt. NMVOCs emissions are in continuous decline since 1980, with an average rate of around -70 kt/year in the 1990s, -100 kt/year in the 2000s, -20 kt/year in the years 2010.

NMVOC – target 2020 (Göteborg-2)  already met 

Period covered: 2020  |  Ceiling to be reached: 670 kt (-43% compared to 2005)  Actual emissions: 612 kt in 2017

 

Other targets

Minamata Convention (Hg – mercury)

This target does not directly aim to reduce emissions but the manufacture, import and export of mercury-based products.

more

The Minamata Convention on Mercury was formally adopted on October 10, 2013 under the aegis of UN Environment (formerly UNEP) and entered into force in 2017. It is aimed at, inter alia, reducing mercury atmospheric emissions originating from five stationary source categories: coal electricity production plants, coal powered industrial boilers, non-ferrous metals smelting, waste incineration plants, cement plants. After ratification by EU as economic integration regional organization and seven of its 28 Member States (Bulgaria, Denmark, Hungary, Malta, Netherlands, Romania and Sweden) mid-May 2017, the Convention entered into force on 16 August 2017. France ratified it on 15 June 2017.
