Teleworking: calculate your impact reductions

Teleworking allows you to act in favor of the ecological transition. By reducing the number of home-work commute with your vehicle, you reduce your pollutant emissions (such as fine particles) and your greenhouse gas emissions (such as CO₂ ).

Through this reduction in emissions, you save money as an individual (reduced fuel consumption) as well as for the community (reduced impact of local pollution on health and the environment).

What is the difference between pollutant emissions and greenhouse gas emissions ?

Atmospheric pollutants are substances that can accumulate in ambient air in concentrations high enough to threaten human and animal health, or damage vegetation and structures. Pollutants can be of natural origin (volcanoes, pollens...) or result from human activities (road traffic, urban heating, agriculture, industrial processes...).

Greenhouse gases (GHG) are substances that retain part of the solar radiation reflected by the earth. Thus, their accumulation in the atmosphere results in an increase in global temperature. GHGs can be of natural origin (water vapor, photosynthesis, animal emissions, etc.) or from human activities (thermal power stations, road transport, etc.).

This simulator is completely free and anonymous. No data is stored or sold to third parties.

Only Airea uses your data for calculation purposes.

Carbon dioxide (CO₂) :

CO2

VOC:

VOC

Nitrogen dioxide (NO₂):

NO2

Carbon dioxide (CO₂) is a non-toxic gas for human health with ubiquitous concentrations in ambient air. It is the main greenhouse gas in its natural state (along with water vapor). It is emitted by humans during the combustion of fossil fuels (industry, road traffic, etc.) and contributes to global warming (particularly stable, its lifetime in the atmosphere is around 100 years). Global concentrations have been rising steadily since pre-industrial times, and now stand at around 416 ppm.

The family of volatile organic compounds (VOCs) contains many pollutants including unburned hydrocarbons. Their emissions come mainly from incomplete fuel combustion and evaporation. These compounds are mainly emitted by gasoline engines, but the introduction of catalytic converters since the early 1990s (Euro 1 standard) and processes for limiting fuel evaporation have gradually reduced emissions from these vehicles. Once emitted in the exhaust, VOCs contribute to the formation of ozone and fine particles in the ambient air. Some of these compounds are also harmful to health (benzene is classified as a known human carcinogen by the IARC).

Nitrogen dioxide (NO₂) is mainly emitted by road traffic. This compound is mostly emitted by diesel engines. Despite the lowering of emission thresholds as Euro standards evolved, measurements in real-life conditions showed that these emissions stagnated until the appearance of Euro 6 vehicles. In major French conurbations, NO₂ concentrations exceed regulatory thresholds and WHO recommendations. This pollutant has short-term and long-term effects on health (respiratory system).

Particulate Matter (PM₁₀-PM₁):

Methane (CH₄):

CH4

Carbon monoxide (CO) :

Methane (CH₄) is a greenhouse gas with a high global warming potential (about 25 times greater than CO₂). Despite its lower emissions than CO₂, it is thus the second-largest contributor to global warming according to the World Meteorological Organization (WMO). In addition, CH₄ emissions also have an indirect impact on air quality as a precursor to ozone (O₃).

Particulate matter (PM) is emitted from vehicle exhausts (incomplete combustion of fuels, etc.) but also from non-exhaust sources (road wear from passing vehicles, tire and brake pad wear). Particles emitted in the exhaust have a small particle size (aerodynamic diameter less than 2.5 µm) while non-exhaust emissions are larger (PM2.5-PM10 fraction). Historically, the highest particle emissions have come from diesel engines (diesel particles classified as carcinogenic to humans by the IARC in 2012), but these have been falling sharply since the introduction of particulate filters (Euro 3 and higher standards). Since the Euro 6 standard, regardless of the type of engine (gasoline or diesel), vehicles emit mainly ultra-fine particles, which can only be counted by number (and not by mass) but these are not taken into account in this calculator, as there is as yet no a reliable emission factor for this parameter.

Carbon monoxide (CO) emissions result from the incomplete combustion of fuels. CO can accumulate to toxic concentrations when emitted indoors (around 100 deaths per year in France), but its concentrations in outdoor air are well below health thresholds.

Nitrous oxide (N₂O) :

N2O

Ammonia (NH3) :

NH3

Sulfur dioxide (SO₂) :

SO2

Nitrous oxide (N₂O) is a greenhouse gas emitted overwhelmingly by the agricultural and industrial sectors. Vehicles have also been emitting N₂O since the advent of catalytic converter exhaust systems. Although nitrous oxide emissions from road traffic are marginal, they are taken into account because N₂O is a powerful greenhouse gas with a global warming potential (GWP) around 310 times higher than CO₂. It therefore contributes, along with CO₂ and CH₄, to global warming. In addition, N₂O contributes to the phenomenon of destruction of the ozone layer.

Ammonia (NH₃) is a pollutant emitted 98% by the agricultural sector. However, road traffic is also an emitter of NH₃, mainly by gasoline-powered vehicles. This pollutant presents a major health and environmental challenge, as it is involved on the one hand in acidification and eutrophication of environments, and on the other, in the degradation of air quality (formation of secondary aerosols). The independent NGO ICCT therefore recommends that an emissions threshold for NH₃ should henceforth be taken into account for the new Euro standards.

Initially, sulphur dioxide (SO₂) emitted from vehicle exhaust was mainly linked to the oxidation of sulphur contained in road fuels, particularly for diesel engines. SO₂ emissions from road traffic have nevertheless been significantly reduced since the 1990s by desulfurizing fuels to optimise the operation of post-treatment systems (catalysts, DPF).

Air pollution has a cost for society. The cost in € per ton of a pollutant is evaluated in various scientific programs and studies, based on elements such as :

The impact on public health (costs of hospitalizations, deaths, etc.)
The impact on the environment (reduced biodiversity, drop in agricultural yields, deterioration of buildings, etc.)
The economic impact (lower productivity due to sick leave, etc.)
