Initiatives have been taken to develop an extensive inventory of greenhouse gases (GHG) emission sources in Delhi. However, there is a need to integrate the emission of air pollutants and GHG, which may have significant overlap and may require a common strategy to mitigate these emissions.

Patents and other intellectual property such as know-how are a complex issue for policy makers and civil society experts, especially considering the large number of patents involved and the sensitivity and confidentiality around licensing agreements. This paper does not attempt to offer a solution to the patent debate.

The use of hydrofluorocarbons (HFCs) is expected to rapidly rise in the coming decades unless more is done to curb their growth.

Hydrofluorocarbons (HFCs) are often used as substitutes for ozone-depleting substances (ODSs) in various sectors, including refrigeration, air-conditioning, aerosols, fire extinguishers, and foam blowing.

To understand the impediments that IPR poses for a successful phase-down of HFCs in developing countries, Centre for Science and Environment (CSE) and Council for Scientific and Industrial Research-Unit for Research and Development Information Products (CSIR-URDIP) carried out a study of the number and nature of patents filed in India around the

IIn 1987, the Montreal Protocol phased out the use of chlorofluorocarbons (CFCs), an ozone-depleting substance (ODS) used as coolants in refrigeration and air conditioning. Unfortunately, the chemicals increasingly being deployed in their place, hydrofluorocarbons (HFCs) are themselves exceptionally potent greenhouse gases.
