CNG is safe, as clean as Euro-VI compliant diesel

BRAND NEW DELHI: NGO Centre with regard to Science and Environment offers critically analyzed a Authorities of Scientific and Commercial Research study, jointly carried out by Indian native Institute of Petroleum and also the University of Alberta, upon presence of pollution-causing nanoparticles in CNG and diesel powered bus exhausts.

This was according to claims made by M To Garg, director general associated with CSIR, who had recently discussed the findings of the study-that the number of nanoparticles released through CNG buses is greater than that from diesel busses but the mass of nanoparticles emitted from CNG chartering is relatively lower.

CSE's evaluation, however , reveals that the CSIR study findings are different from exactly what Garg's briefing may have communicated. Garg had been referring to nanoparticle emissions from an Indian CNG bus and a Canada-made diesel-powered bus meeting advanced ALL OF US tier-II standards. US tier-II norms are tighter compared to Euro VI norms.

CSE accessed the draft research by CSIR only to discover that CNG buses performed method better than diesel on just about all pollution parameters-including nanoparticles. CNG's performance is close to or even better than Euro VI release standards for diesel which are yet to be implemented within India.

"This motivated strategy against CNG buses inside India will harm not just the CNG bus program that has given enormous public well-being benefits but also jeopardize the actual policy decision to leapfrog emissions standards to Dinar VI by 2020 to slice dangerous diesel emissions. The federal government of India is pulling its feet in encounter of strong opposition through the diesel industry, " CSE's statement issued on Mon said.

The study involved performing emission tests on 2 Indian CNG buses as well as two diesel buses (when they were mobile)-one of a Canadian make that meets PEOPLE tier II standards when you have advanced particulate filters and also another an Indian diesel engine bus without any filter or perhaps diesel trap.

The results revealed that nanoparticle emissions coming from Indian diesel buses had been 600 to 2, 000 times more than those from your CNG bus. But when the particular CNG bus was in contrast to the Canadian diesel tour bus with particulate matter tiger traps and advanced nitrogen oxides control meeting US tier-II standard, the study found nanoparticle levels for CNG to become 12-40 times higher. The actual Indian diesel bus without having particulate matter trap had been found emitting 28, 000 times more nanoparticles when compared to Canadian bus.

CSE features that CNG performed far better on other pollution variables as well-carbon monoxide, non-methane hydrocarbons and nitrogen oxides. Both CO and NMHC emissions from CNG vehicles in use are close to the restrict values of Euro MIRE norms.

"CSIR should have released a red flag immediately along with urged the government to leapfrog to Euro VI emissions standards for diesel. Nanoparticles, being of 0. one micrometres in width, are twenty five times smaller than PM2. five and go directly into typically the bloodstream. In conjunction with PM2. a few and PM1, they trigger irreparable damage. PM2. your five is already the fifth biggest killer in India, inch a CSE researcher additional.

Anumita Roy Chowdhury, mind of CSE's Clean Air advertising campaign, said, "CSIR has disregarded to mention the serious health danger associated with diesel emissions. It is currently well known that WHO has figured diesel exhaust is a human being carcinogen and is in the exact same class as tobacco because of its strong link with chest cancer. "

In its statement on August 8, depending on interviews with Garg along with other experts, TOI highlighted which CNG is far cleanser than non-low sulphur diesel-engined. Its nanoparticle numbers, although, can be marginally higher than that will in emissions from low-sulphur diesel vehicles meeting European V/VI norms.
