+ | In the Fuel Combustion category, **Road Transport (NFR 1.A.3.b)** is responsible for about three quarters of the 1990 Fuel Combustion emissions, with **Passenger Cars (NFR 1.A.3.b i)** emitting nearly all of it. Reductions of about 95% in those categories between 1990 and 2021 are mainly due to increasingly stricter regulations, | ||
Furthermore the implementation of the Technical Instruction on Air Quality Control (TA-Luft 2002), to decreases in emissions from **petrol storage and from fuelling of motor vehicles (1.B.2.a.v)** - as a result of implementation of the 20th and 21st Ordinances on the Execution of the Federal Immission Control Act (BImSchV) - and to reduced petrol consumption play a major role in the reduction of NMVOC emissions within the category **Fugitive Emissions from fossil fuels (NRF 1.B.2)**. | Furthermore the implementation of the Technical Instruction on Air Quality Control (TA-Luft 2002), to decreases in emissions from **petrol storage and from fuelling of motor vehicles (1.B.2.a.v)** - as a result of implementation of the 20th and 21st Ordinances on the Execution of the Federal Immission Control Act (BImSchV) - and to reduced petrol consumption play a major role in the reduction of NMVOC emissions within the category **Fugitive Emissions from fossil fuels (NRF 1.B.2)**. | ||
