Celebrating the 25 years of The Montreal Protocol

Despite all the gloom and doom of current events, there are reasons to celebrate, and to hope as the Montreal Protocol turned 25. This was at the time – and it still is – a huge success on environmental and climate issues. Indeed, the World Bank noted that ” The Montreal Protocol, by controlling the consumption … Read more

HFCs rising use could accelerate global warming

To CleanTechies : ” The increased use of hydrofluorocarbons (HFCs) in the production of refrigerators, air conditioners, and other products could play a significant role in accelerating global warming “

The United Nations Environmental Program (UNEP) study notes that the projected emissions of HFCs by 2050 could equal nine billion tons of carbon dioxide — or about one-third of current CO2 emissions.

HFCs were introduced in the 1990s to replace chlorofluorocarbons (CFCs), which were a threat to  the ozone layer. So, this was a good idea with a strong downside.

The hole in the ozone layer starts diminishing

According to the UNEP : ” International efforts to protect the ozone layer are a success and have stopped additional ozone losses and contributed to mitigating the greenhouse effect.”

I believe we should capitalize on the success governments around the world achieved in 1987. We should do something for the 25th anniversary and go further with a global agreement on greenhouse gases emissions.

The Montreal Protocol cut emissions in an important way but a more targeted action is needed soon on other air pollutants like carbon dioxide and methane…

The motivating example of the Montreal Protocol

ozone-layerIn 1988 was signed the Montreal Protocol, which restricted the use of CFC – ChloroFluoroCarbons – gases that harm the ozone layer, our sole protection against UV rays.

To the NASA this was a tremendous success as large troubles have been avoided. Without this success, our world could suffer of massive DNA mutations induced by massive UV radiations.

If 193 countries signed a treaty to avoid this, could they do the same 20 years later to avoid climate change, biodiversity loss or oceans pollution. I want to believe we can !
