The phrase "a system of emissions" is correct and usable in written English.
It can be used when discussing frameworks or structures related to the release of substances, typically in environmental or regulatory contexts.
Example: "The government has implemented a new policy aimed at reducing a system of emissions from industrial sources to improve air quality."
Alternatives: "an emissions framework" or "a framework for emissions".
LONDON — Europe, which led the world in creating a system of emission permits to combat greenhouse-gas emissions, dealt a potential death blow to that system on Tuesday.
In these pages Mr. Pooley deftly explicates the political maneuvering surrounding the controversial concept of "cap and trade" (a mandatory and declining limit on carbon emissions, combined with a system of tradable emissions permits) and does a suspenseful job of recounting the walk-up to last year's extremely close vote in the House (219 to 212), passing a climate change bill.
It does not explicitly recommend a cap-and-trade system, but says that such a system of tradable emissions permits would give industry more flexibility in meeting an emissions target or budget.
At the heart of attempts to curb carbon dioxide emissions are two related proposals: taxation of those emissions and a system of tradable emission permits, also known as cap and trade.
Even some early devotees of a system of tradable emissions permits believe that it will not work for carbon dioxide, by definition a planetary problem.
What has caught on instead is a variant that most economists consider more or less equivalent: a system of tradable emissions permits, a k a cap and trade.
For example, instead of fossil fuels alone being required, the introduction of a system of carbon emissions permits brings in a new type of property required to make and supply a product, in addition to the fossil fuels themselves.
In exchange, developing countries including China and India, agreed in principle to a transparent system of emissions reporting so the world could see whether all governments were meeting voluntary targets.
The rules would also allow manufacturers that exceeded the limits to pool their emissions with less-polluting manufacturers — a provision that could create the basis for an industrywide system of emissions trading.
Cap-and-trade, a system of controlling carbon emissions by putting a price on them and therefore creating economic incentives for businesses to cut energy use — and for investors to back new businesses creating energy from renewable sources — was abandoned by Congress in 2009, leaving the regional group and the California system to forge new markets on their own.
