First halocarbon emissions from India

July 20, 2019 | Filed under: Greenhouse gas measurements, Inverse modeling

Based on measurements we collected on the UK’s research aircraft in 2016, we have derived the first regional inverse modeling based estimates from India (Say et al., 2019). We show that CFCs are not in widespread use and there is a mix of HFC and HCFC usage, which is expected for an Article 5 country like India.

India’s 2016 halocarbon emissions derived from atmospheric measurements and the fraction of the global total.

Finally, we show that India was emitting HFC-23 in 2016, after funding from the Clean Development Mechanism ceased. This implies that if HCFC-22 manufacturers were abating HFC-23 emissions during the period of the CDM, some or all of the manufacturers resumed venting afterward. It will be interesting to see whether HFC-23 emissions are still continuing despite legislation in India that was announced in October 2016 that makes abatement mandatory.

India’s HFC-23 emissions from inventories and the estimates from our study in 2016.
