European Commission (EC) President Jean-Claude Juncker on Friday said that the G20 needs to issue a strong declaration about climate change in its summit, which is set to kick off later in the day in this Japanese city.

Juncker made the statement after being asked in a press conference over his expectations for the final declaration over climate change set to be signed by G20 leaders during the two-day meet, reports Efe news.

“We need a strong declaration on climate change,” said Juncker, recalling the debacle in this regard in the last G20 summit in Buenos Aires in December.

In that meeting, the members of the group agreed on a document supporting the fulfilment of the Paris Agreement against climate change, although the US abstained from signing the declaration after President Donald Trump’s administration had earlier unilaterally withdrawn from the 2015 climate change deal signed in the French capital.

The possible opposition of the United States makes it difficult for the G20 to agree on a more substantial text, making it likely that the declaration would be limited to supporting the Paris Agreement, according to official sources from Japan, which currently holds the rotating chairmanship of the group.

Both Juncker and European Council President Donald Tusk said that the delegations were still working on the final draft of the declaration and hoped to make further progress.

Meanwhile, a group of environmental activists on Thursday protested outside a coal plant in the Japanese city of Kobe with an inflatable balloon effigy of Japanese Prime Minister Shinzo Abe, as a show of opposition against his policies of promoting and funding coal power plants.

New automotive technology that promises enhanced fuel efficiency may have a serious downside, including significant climate and public health impacts, a new study suggests.

The gasoline direct injection (GDI) engine is one of the most prominent technologies car manufacturers adopted to achieve the fuel economy and carbon dioxide emission goals established in 2012 by the US Environmental Protection Agency.

While this technology is credited with boosting fuel efficiency and reducing CO2 emissions, GDI engines produce more black carbon aerosols than traditional port fuel injection engines, according to the study published in the journal Environmental Science and Technology.

“Even though emissions from gasoline vehicles constitute a small fraction of the black carbon in the atmosphere, the vehicle emissions are concentrated in regions with high population densities, which magnifies their effect,” said study researcher Rawad Saleh, Assistant Professor at University of Georgia in the US.

The market share of GDI-equipped vehicles increased from 2.3 per cent in model year 2008 to 51 per cent in model year 2018. The EPA projects 93 per cent of vehicles in the US will be equipped with GDI engines by 2025. According to the study, researchers predicts the increase in black carbon emissions from GDI-powered vehicles will fuel climate warming in urban areas of the US that significantly exceeds the cooling associated with a reduction in CO2.

In addition, they believe the shift will nearly double the premature mortality rate associated with vehicle emissions, from 855 deaths annually to 1,599. The researchers estimate the annual social cost of these premature deaths at $5.95 billion. The increase of black carbon is an unintended consequence of the shift to GDI-equipped vehicles that some scientists suspected was based on experimental data, according to the researcher.

“This study is the first to place these experimental findings in a complex modeling framework to investigate the trade-off between CO2 reduction and an increase in black carbon,” Slah said. While previous research has reported the shift to GDI engines will result in net benefits for the global climate, the researchers said that these benefits are rather small and can only be realized on timescales of decades.

Meanwhile, the negative impact of black carbon can be felt instantaneously, they added.

“Our research shows the climate trade-off is much different on the regional scale, especially in areas with high vehicle densities. In these regions, the climate burden induced by the increase in black carbon dominates over the climate benefits of the reduction in CO2,” said Saleh. (IANS)
