| description | <p>Global emissions of the ozone-depleting gas HCFC-141b (1,1-dichloro-1-fluoroethane, CH<span class="inline-formula"><sub>3</sub></span>CCl<span class="inline-formula"><sub>2</sub></span>F) derived from measurements of atmospheric mole fractions increased between 2017 and 2021 despite a fall in reported production and consumption of HCFC-141b for dispersive uses.
HCFC-141b is a controlled substance under the Montreal Protocol, and its phase-out is currently underway, after a peak in reported consumption and production in developing (Article 5) countries in 2013.
If reported production and consumption are correct, our study suggests that the 2017–2021 rise is due to an increase in emissions from the bank when appliances containing HCFC-141b reach the end of their life, or from production of HCFC-141b not reported for dispersive uses.
Regional emissions have been estimated between 2017–2020 for all regions where measurements have sufficient sensitivity to emissions.
This includes the regions of northwestern Europe, east Asia, the United States and Australia, where emissions decreased by a total of 2.3 <span class="inline-formula">±</span> 4.6 Gg yr<span class="inline-formula"><sup>−1</sup></span>, compared to a mean global increase of 3.0 <span class="inline-formula">±</span> 1.2 Gg yr<span class="inline-formula"><sup>−1</sup></span> over the same period.
Collectively these regions only account for around 30 % of global emissions in 2020.
We are not able to pinpoint the source regions or specific activities responsible for the recent global emission rise.</p> |
