Dear Hr-Saloni,
"Human Rights" is a far wider and comprehensive subject. While framing the constitution for the country, the framers of the constitution have ensured that human rights are intrinsic to it. The constitutional safeguards ensure that the legislative bodies do not pass a single bill that is violative of human rights. Therefore, adherence to the various laws of the land in itself is sufficient, and there is no need for a private limited company to design a policy over and above these laws.
Your second query is on the policy on the environment. If you adhere to the rules and regulations of the pollution control board of your state, it will take care of the environment. Nevertheless, going beyond these rules and regulations, a few companies have gone beyond and have adopted green practices. Their aim is to take measures to reduce carbon emission and global warming. However, you have not mentioned the nature of your industry, what your finished product or service is, why the need for the policy was felt and so on. Sans this information, how can the average member of this forum, who knows nothing about your company provide the suggestions?
Thanks,
Dinesh Divekar
