The EIA claims these "are not isolated incidents but common practice throughout the industry".
Traders and buyers of CFC-11 in China told the EIA that it is used in the majority of China's rigid PU foam sector.
A few months ago, there were reports that while the ozone layer was recovering all over the world, researchers were able to still find some traces of risky CFC which at the time was reported to be coming out of East Asia.
Several companies also referred to the ease with which CFC-11 could be exported in the pre-blended polyol compound used to make the foams, it added.
The foreign ministry told AFP on Monday that China had made "tremendous contributions" to achieving the aims of the Montreal Protocol.
A new survey by the Environmental Investigations Agency (EIA) has found that China is at least partially responsible for the mysterious spike of atmospheric levels of chlorofluorocarbons (CFCs), heat-trapping substances that have been banned worldwide for years.
CFCs were commonly used from the 1930's in aerosols, solvents and refrigerants without any knowledge of the dangers to the environment.
The mystery of the excessive amounts of banned CFC-11 (tricholorofluromethane) in the atmosphere seems to have been solved.
Yuan, Aussie hit as USA threatens more tariffs on China
Mr Trump has threatened to tax $550bn (£415bn) in Chinese products - exceeding America's total imports from China a year ago . Some U.S. business groups and lawmakers from Trump's own Republican Party were critical of the escalating tariffs.
The Chinese government is yet to respond to these allegations, but will address this matter soon, according to the NY Times.
"An immediate and effective clampdown of the illegal use of CFC-11 in China is critical to ensuring the recovery of the ozone layer", it says.
"CFC-11 is also a super global warmer, making this a serious threat for our climate as well", he added. What we've uncovered is a systemic problem, not isolated incidents. "We want them to clamp down but it's supremely important for them to carry out a comprehensive investigation into the sector".
EIA is releasing the report in advance of the Open-Ended Working Group of the Montreal Protocol meeting in Vienna from 11-14 July, where the issue of the rogue CFC-11 emissions is likely to be high on the agenda.
They went to Kigali, Rwanda, to eliminate hydrofluorocarbons (HFCs) and take 0.5C out of future global warming, and the 170 countries that successfully negotiated an amendment to the Montreal protocol treaty agreed to get rid of 90% of them. In fact, the Montreal Protocol is considered the world's most successful environmental agreement, mainly because it gives countries financial assistance for substitution.
In May this year, Nature magazine released a study showing that the reduction of banned chlorofluorcarbons (CFCs) which contribute to the destruction of the ozone layer has slowed by nearly half, indicating that someone, somewhere was producing the chemical.
One seller of CFC-11 estimated that 70% of China's domestic sales used the illegal gas.
Brent crude fell $2.10, or 2.7 percent, to a low of $76.76 before recovering slightly to $77.20, down $1.66, by 1208 GMT. Isolating Iran could sideline millions of barrels of oil per day from a market with little spare capacity left.
President Xi, the president of China, is taking a much longer view than Trump because China's presidency doesn't have term limits. Wansleben added that China also needed to change its positions in many areas, "but there's definitely more room for improvement".
The keys she turned in belonged to a Nissan Infiniti rather than a Sentra, leaving the manager "slightly confused", said police. The owner said he had ducked into Walmart and returned to find his auto missing from the parking lot, according to police.
The Netanyahu government is detemined to keep fighters loyal to Assad and to Iran out of the Syrian Golan border area near Israel. Russia, another top key ally of Assad, has warned it would be unrealistic to expect Iran to fully withdraw from the country.
The tubes will be handed off to the rocket which will then blast off and hopefully make its way back to Earth. NASA and ESA signed a letter of intent in April 2018 to pursue a Mars Sample Return mission.
The country's gross domestic product (GDP) surged to $2.597 trillion at the end of 2017, compared to France's $2.582 trillion. The US topped the list, with a GDP of $19.390 trillion, followed by China, which had a GDP of $12.237 trillion.
The officer in charge at Kolkata's Girish Park police station has accepted the complaint which is yet to be verified. It is one of the dialogues mouthed by Gaitonde that prompted 37-year-old Rajiv Sinha to type his complaint.
He credited Trump, saying North Atlantic Treaty Organisation countries are investing more on defense because of his leadership. At the pre-summit breakfast meeting he launched straight back to his theme.
