The ZED scheme encourages the MSME sector to manufacture products with zero defect and zero effect on the environment. This can lead to: Assured customers, Reduced wastage, Increased productivity, Expanded markets, Energy savings.
The Ministry of MSME also provides support to MSMEs under the ZED certification scheme. This includes:
•Financial assistance for testing, quality, and product certification
•Subsidy on handholding support
•Subsidy on technology up gradation for zero effect solutions
MSMEs that submit a ZED certificate receive a 25% concession on processing fees. The government also provides up to Rs 5 lakh per MSME for handholding and consultancy support to help them move towards ZED solutions.

A cloudburst is a natural phenomenon that involves a sudden, heavy downpour of rain over a small area, usually within 20–30 square kilometers. Cloudbursts are defined by the amount of rainfall, with the India Meteorological Department (IMD) classifying 100 mm of rain as a cloudburst in one hour. Cloudbursts can also be accompanied by hail and thunder.
Cloudbursts are a type of geo-hydrological hazard that can cause erosion and inundation, resulting in significant losses. They often occur in high-altitude regions, such as hills and mountains, due to low-pressure areas that form at the top of mountains. These low-pressure areas accumulate clouds with great force, resulting in orographic precipitation.
In India, cloudbursts are generally observed in the Himalayan region. For example, a cloudburst triggered by heavy rains caused one person to drown and four others to go missing in the Himachal Pradesh landslide.
Lightning can heat the air it passes through to 50,000 degrees Fahrenheit, which is five times hotter than the surface of the sun. The intense electrical current from a lightning strike causes the air around it to heat up instantly. This causes the air molecules to expand explosively. The air then rapidly cools and contracts immediately after the flash.
