Historic Global Greenhouse gas emission Agreement signed in Kigali

A historic global climate deal was reached in Kigali, Rwanda at the Twenty-Eighth Meeting of the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer (MOP28).

The so called Kigali Amendment which amends the 1987 Montreal Protocol aims to phase out Hydrofluorocarbons (HFCs), a family of potent greenhouse gases by the late 2040s.

Under Kigali Amendment, in all 197 countries, including India have agreed to a timeline to reduce the use of HFCs by roughly 85% of their baselines by 2045.

What are Hydrofluorocarbons (HFCs)?

  • HFCs are a family of greenhouse gases (GHGs) that are largely used in refrigerants in home, car air-conditioners and air sprays etc.
  • These factory-made gases had replaced CFCs under the 1987 Montreal Protocol to protect Earth’s fragile protective Ozone layer and heal the ozone hole over the Antartica.

Why they are harmful?

  • In recent times, it was found that HFCs have several thousand times capacity in retaining heat in the atmosphere compared to carbon dioxide (CO2), a potent GHG.
  • Thus, it can be said that HFCs have helped ozone layer but exacerbated global warming.
  • Currently, HFCs are currently the world’s fastest GHGs, with emissions increasing by up to 10% each year.

What is significance of the Kigali Amendment?

  • The Kigali Amendment amends the 1987 Montreal Protocol that was designed to close growing ozone hole in by banning ozone-depleting coolants like chlorofluorocarbons (CFCs).
  • Thus, amended Montreal Protocol which was initially conceived only to plug gases that were destroying the ozone layer now includes HFCs responsible for global warming.
  • This move will help to prevent a potential 0.5 degree Celsius rise in global temperature by the end of the century.
  • The Kigali Agreement or amended Montreal Protocol for HFCs reduction will be binding on countries from 2019.
  • It also has provisions for penalties for non-compliance. Under it, developed countries will also provide enhanced funding support estimated at billions of dollars globally.
  • The exact amount of additional funding from developed countries will be agreed at the next Meeting of the Parties in Montreal in 2017.

Different timelines under Kigali Amendment

  • All signatory countries have been divided into three groups with different timelines to go about reductions of HFCs.
  • First group: It includes richest countries like US and those in European Union (EU). They will freeze production and consumption of HFCs by 2018. They will reduce them to about 15% of 2012 levels by 2036.
  • Second group: It includes countries like China, Brazil and all of Africa etc. They will freeze HFC use by 2024 and cut it to 20% of 2021 levels by 2045.
  • Third group: It includes countries India, Pakistan, Pakistan, Iran, Saudi Arabia etc. They will be freezing HFC use by 2028 and reducing it to about 15% of 2025 levels by 2047.

How it is different from Paris agreement?

  • The Paris agreement which will come into force by 2020 is not legally binding on countries to cut their emissions.
  • The Kigali Amendment is considered absolutely vital for reaching the Paris Agreement target of keeping global temperature rise to below 2-degree Celsius compared to pre-industrial times.

India to eliminate use of HFC-23 by 2030

India has decided to eliminate use of HFC-23, a greenhouse gas (GHG) that harms the ozone layer by 2030. With this, India, is taking the lead on tackling climate change.

It was announced during the 28th Meeting of the Parties to the Montreal Protocol at Kigali in Rwanda. In this meeting, final negotiations are taking place to substantially reduce the use of HFCs (hydrofluorocarbons) by 2030.

Key Facts

  • The elimination will potentially check emissions of HFC-23 equivalent to 100 million tonnes of CO2 over the next 15 years.
  • Indian companies will not be compensated for the costs involved in ensuring that these gases are not released.
  • This move is considered as a major break away from the concept of financial assistance for every action on environment in which India earlier had shown the lead.

What is HFC-23?

HFC-23 is a by-product of HCFC-22 (Hydrochloroflurocarbon-22), which is used in industrial refrigeration. It is a potent greenhouse gas (GHG) with global warming potential of 14,800 times more than that of CO2.

What is Montreal Protocol?

  • The Montreal Protocol, is an international treaty designed to protect the ozone layer. It came into force in 1989.
  • It aims at reducing the production and consumption of ozone depleting substances (ODS) in order to protect the earth’s fragile ozone layer.
  • It has been ratified by 197 parties making it universally ratified protocol in United Nations history.
  • It is also highly successful international arrangement, as it has phased-out more than 95% of the ODS so far in its main mandate less than 30 years of its existence.
