Japanese environment minister Shinjiro Koizumi: Japan has just raised its target for reducing carbon emissions from 26 per cent to 46 per cent (by 2030 from 2013 levels). But how was this figure arrived at, environment minister Shinjiro Koizumi was asked? Through a careful analysis of the threat and a realistic assessment of what could be achieved, taking all relevant factors into consideration? Well, er no, according to Koizumi, the number 46 just appeared to him in ‘silhouette’ in a sort of vision.
Shinjiro Koizumi, son of former prime minister Junichiro Koizumi, made the comments in an interview with the TV station TBS last weekend. The interviewer, despite her face mask, was clearly stunned by the revelation that the country’s emission target did not appear to have any scientific basis. She asked the minister to confirm what he had said; and he did.
- 'Particulate aerosol pollution reductions...led to an increase in surface radiative forcing'
It has been assumed COVID lockdowns and their associated reductions in human CO2 emissions would be a “step in the right direction” with regard to climate change mitigation. But a new study finds the particulate (aerosol) pollution reductions from less industrial and transportation activity in Europe during the months of March to May (2020) actually led to an increase in surface radiative forcing ~65 times greater than from business-as-usual CO2 emissions.
