What Is BS6 Phase 2?

Are you curious to know what is BS6 phase 2? You have come to the right place as I am going to tell you everything about BS6 phase 2 in a very simple explanation. Without further discussion let’s begin to know what is BS6 phase 2?

In a world grappling with climate change and pollution concerns, environmental regulations have become more stringent to reduce harmful emissions and improve air quality. In India, the Bharat Stage 6 (BS6) emission standards, also known as BS6 Phase 2, have been introduced as a significant step forward in curbing vehicular pollution. This blog will explore what BS6 Phase 2 is, its significance, and the impact it has on the automotive industry and the environment.

What Is BS6 Phase 2?

BS6, which stands for Bharat Stage 6, is an emission standard introduced in India to regulate the permissible limits of pollutants emitted by internal combustion engine vehicles, primarily those using gasoline and diesel as fuels. BS6 Phase 2 is the second phase of the implementation of these stricter emission standards, building upon the foundation set by BS6 Phase 1.

Key Features Of BS6 Phase 2:

  1. Lower Emission Limits: BS6 Phase 2 introduces even more stringent emission limits compared to Phase 1. This means that vehicles must emit significantly fewer pollutants, such as carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), and particulate matter (PM).
  2. On-Board Diagnostics (OBD): OBD systems are mandated in BS6 Phase 2 vehicles. These systems continuously monitor the performance of the vehicle’s emission control components, making it easier to detect and rectify malfunctions that could increase emissions.
  3. Real-World Driving Emissions (RDE): BS6 Phase 2 includes RDE testing, which assesses vehicle emissions under real-world driving conditions, ensuring that vehicles perform well in actual usage, not just in controlled laboratory settings.
  4. Introduction of CNG Vehicles: Under BS6 Phase 2, there is a push for more eco-friendly Compressed Natural Gas (CNG) vehicles, which produce fewer emissions and reduce the environmental impact of transportation.
  5. Improved Fuel Quality: To complement the stricter emissions standards, cleaner and higher-quality fuels are required, making a significant difference in reducing vehicle emissions.

Significance Of BS6 Phase 2

  1. Improved Air Quality: The primary goal of BS6 Phase 2 is to significantly reduce harmful emissions from vehicles, leading to better air quality. Lower emissions of NOx and PM are especially crucial as they are linked to respiratory and cardiovascular diseases.
  2. Climate Impact: Lower emissions also have a positive impact on greenhouse gases, contributing to India’s commitment to reduce its carbon footprint.
  3. Public Health: Reduced air pollution means improved public health. BS6 Phase 2 standards are expected to decrease the number of premature deaths and cases of respiratory illnesses caused by air pollution.
  4. Technological Advancements: The implementation of BS6 Phase 2 has encouraged the automotive industry to develop more efficient and cleaner engine technologies, promoting innovation in the sector.

Challenges And Impact On The Automotive Industry

While BS6 Phase 2 standards are a positive development for the environment and public health, they present challenges for the automotive industry. Meeting these stricter standards requires significant investments in research and development to develop cleaner and more efficient engine technologies. As a result, it has led to an increase in the cost of vehicles.


BS6 Phase 2 represents a pivotal moment in India’s efforts to combat air pollution and reduce its environmental impact. By setting more stringent emission standards and promoting the use of cleaner fuels, it significantly contributes to improving air quality, public health, and India’s commitment to addressing climate change. While it poses challenges to the automotive industry, it also fosters innovation and technological advancement. Ultimately, the adoption of BS6 Phase 2 emission standards is a vital step towards a cleaner, healthier, and more sustainable future for India.
