                                                              are given below.

            To strengthen our commitment towards climate             Dedusting system in bagging plant
            change, we have also undertaken a few initiatives to
            measure emissions other than those pertaining to    Use of efficient prill bucket to reduce urea dust
            the plant. We also conducted a preliminary study to
            understand the GHG benefits of extensive green      Natural draft prilling tower with extra height to
            cover in and around the Chambal plants complex.              contain urea dust emissions
