New Emission Norms of Tractors: Deadline extended till October 2021

The central government has extended the deadline of the TREM Stage-IV emission norms. These norms for tractors were scheduled to be applicable from October 2020. Now, the government of India has extended the deadline to October 1, 2021.

Key Facts

  • The ministry of road transport and highways has amended the Central Motor Vehicles Rules, 1989 on September 30, 2020 in order to accommodate the extension.
  • The request for extension was made by the ministry of agriculture, tractor manufacturers and agriculture associations.
  • The amendment also provides a separate emission norms for the agricultural machinery including the power tillers, tractors, harvesters and construction vehicles.
  • These norms has also changed the nomenclature of the emission norms of tractors and other equipment from Bharat State (CEM/TREM) IV and Bharat State (CEV/TREM)-V to TREM Stage IV and TREM Stage V.
  • TREM stands for Transport Emergency and CEV stands for Construction Equipment Vehicle.

Background

The first standard for agricultural tractor that is Bharat (TREM) Stage I was implemented in 1999.  The Bharat (TREM) Stage III A was adopted later to harmonise agricultural tractors and construction machinery under engine category. The Bharat Stage (CEV/Trem) IV was adopted in 2018 for emission standards for engines to be used in construction and agricultural equipment.

Bharat (CEV/TREM) Stage IV

The BS IV standards are aligned with European Union Stage IV standards. Under the norms,

  •  Engines equipped with Selective Catalytic Reduction (SCR) should meet the ammonia emission limit of 25 ppm for engines operating at less than 56 KW while the engines operating at more than 56 KW meet ammonia emission of 10 ppm.
  • Particulate Matter emitted by the engines should be 0.025 gram per KWhr which is irrespective of their power.
  • Emitted Carbon Monoxide should be 5.0 g/KWhr for engines having power less than 130 KW while for engines with power greater than 3.5 g/KWhr should be 3.5.
  • Also, these vehicles should pass the Non-road Steady State Cycle(NRSC) test and  Non-road Transient Cycle(NRTC) test.
