What is a high global warming potential?

High GWP GHGs make up a very small portion of the total greenhouse gas emissions. They are, however, very potent and long-lived, which magnifies their effect on warming. HFCs and PFCs are used as substitutes for the ozone-depleting chemicals that are now restricted under the Montreal Protocol of 1987.

What is the approximate global warming potential of HFC-134a?

Microsites menu

Species Chemical formula Global Warming Potential (Time Horizon)
HFC-134a CH2FCF3 1300
HFC-152a C2H4F2 140
HFC-143 C2H3F3 300
HFC-143a C2H3F3 3800

What is the global warming potential range of Hcfs?

HFCs were developed as alternatives to ozone depleting substances that are being phased-out under the Montreal Protocol. Unfortunately, HFCs have a global warming potential 1000 to 3000 times that of CO2, and their use has increased from almost nothing in 1990 to 1,100 million tonnes of CO2e in 2010.

How do you calculate global warming potential?

You calculate the carbon dioxide equivalent of a quantity of F gas by multiplying the mass of the gas (in tonnes), by the gas’ global warming potential (GWP)….Example calculation

  1. Mass (in tonnes) of F gas multiplied by GWP of F gas.
  2. = (10/1,000) * 3,922.
  3. = 39.2 tonnes CO2 equivalent.

Which one has the highest global warming potential?

Carbon dioxide
Carbon dioxide is used as the base for all the calculations, so its global warming potential is 1. 2 The higher the GWP, the more heat the specific gas can keep in the atmosphere….Table 1: High Global Warming Potential Gases.

Which country produces the most carbon dioxide?

The 20 countries that emitted the most carbon dioxide in 2018

Rank Country CO2 emissions (total)
1 China 10.06GT
2 United States 5.41GT
3 India 2.65GT
4 Russian Federation 1.71GT

Which causes global warming?

Global warming is an aspect of climate change, referring to the long-term rise of the planet’s temperatures. It is caused by increased concentrations of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, and farming.
