We had a meeting regarding it. The incidents of stubble burning are very few now, and the level of pollution is still increasing. Scientists reported 2-3 factors for this. The first is that vehicle pollutions contribution is 36 per cent. The second factor is biomass burning. We made some major decisions after seeing this, Gopal Rai said.To control vehicle pollution, we issued the rules of GRAP 3. To control biomass burning, we have directed the related organisations to monitor this, especially. especially the MCD, Revenue, DDA, and NDMC, are being given this direction for the fires that are breaking out at various places in the parks, he added.
