The primary full form of COP is Conference of the Parties in international diplomacy and climate summits, and Coefficient of Performance in thermodynamics and refrigeration engineering. In global environmental governance, COP is the supreme decision-making body of the United Nations Framework Convention on Climate Change (UNFCCC), where member nations negotiate worldwide treaties to mitigate global warming.
Quick Answer: COP = Conference of the Parties (UN Climate Summit) / Coefficient of Performance (Physics)
What is the full form of COP?
| Short Form | Primary Full Form | Field / Domain |

1. Conference of the Parties (COP): Global climate summits
Established under the United Nations Framework Convention on Climate Change (UNFCCC) adopted at the 1992 Earth Summit in Rio de Janeiro, COP convenes annually to assess global progress in combating climate change:
Landmark COP Summits in history:
- COP3 (Kyoto, Japan - 1997): Formulated the historic Kyoto Protocol, the first international treaty to set legally binding greenhouse gas emissions reduction targets for industrialized nations.
- COP21 (Paris, France - 2015): Adopted the landmark Paris Agreement, committing 196 nations to hold global average temperature increases well below 2 °C above pre-industrial levels, with efforts to limit it to 1.5 °C.
- COP26 (Glasgow, Scotland - 2021): Finalized the Glasgow Climate Pact, securing initial commitments to phase down unabated coal power and finalize the Paris Rulebook.
- COP28 (Dubai, UAE - 2023): Concluded the first Global Stocktake, producing an agreement signaling a transition away from fossil fuels in energy systems.
2. Coefficient of Performance (COP) in HVAC & thermodynamics
In physics and mechanical refrigeration, the Coefficient of Performance (COP) measures the thermodynamic efficiency of heat pumps, air conditioners, and refrigeration compressors:
COP = Desired Heat Output or Removed / Work Input (Electrical Energy)
- High efficiency: A modern residential heat pump with a COP of 3.5 delivers 3.5 kW of thermal heat into a room for every 1.0 kW of electrical power consumed, making heat pumps far more energy-efficient than traditional electrical resistance heaters (which have a maximum theoretical COP of 1.0).
3. Close of Play (COP) in business and cricket
In Commonwealth corporate workplaces (especially the United Kingdom, India, and Australia), COP designates an end-of-day deadline (5:00 PM local office time), originating from cricket where "close of play" marks the end of a match day's scheduled overs.
