Description
Technical field
Measuring method more particularly to a kind of measuring and calculating side of textile carbon emission the present invention relates to a kind of product carbon emission
Method.
Background technology
As global warming exacerbation and extreme climate take place frequently, develop low-carbon economy and circular economy has become common recognition.
2009, China disclosed the target for reducing carbon emission：Until the year two thousand twenty, per GDP CO2 emission declined than 2005
40%~45%.In order to reach the target of carbon emission reduction, science and accurately to calculate carbon emission amount be the first step.
China is the world's largest textile producing country, and energy consumption is high in textile manufacture, carbon emission amount is big, because
The calculating of this textile carbon emission is particularly important China's carbon emission reduction action.Since domestic textile type is various, the energy
It shares that phenomenon is universal with material, substantially increases the difficulty and workload of the calculating of textile carbon emission.And according to existing
Some product carbon emission computational methods only calculate the carbon for setting the production section caused by reserved energy of the product in the production line
Discharge, and the attached production system in addition to production line is had ignored, such as lighting system, air-conditioning system, warehouse logistics system are at this
The carbon emission of the public input part of enterprise during production causes the carbon emission calculated value of production cycle not comprehensive, inaccurate, respectively
The carbon emission calculated value of product is relatively low.
Invention content
The object of the present invention is to provide a kind of measuring methods for textile carbon emission, are existed by calculating single textile
The carbon-based industry footprint of entire production cycle, the carbon of carbon emission, the public input part of enterprise including production line production and processing part
Discharge；Using yield disassembly principle, the proportionate relationship of product yield and public input amount are connected, i.e. yield and total output
Ratio be equal to the ratio of input amount and total input amount, enterprise's input amount during production single textile is calculated, so as to calculate
The carbon emission of public input part during the product is produced, the carbon emission of production section and common portion is stacked up, is calculated
Certain total carbon emissions of weaving single product in the production cycle calculates incomplete defect to solve existing textile industry carbon emission, subtracts
Few error improves the science of textile industry carbon emission amount calculating.
The characteristics of by analyzing textile enterprise, it is contemplated that during production and processing, the energy and the material of textile enterprise share
The phenomenon that common scenario, in addition also have attached production system in addition to production line, such as lighting system, air-conditioning system, warehouse object
The public input such as streaming system, therefore the carbon emission of enterprise's common portion is contemplated that during calculating carbon emission.It is managed based on industrial carbon footprint
By method《GHG-Protocol-Chinese》, provided by the present invention for the measuring method of textile carbon emission, it is divided into measuring and calculating
The carbon emission of the public input part of carbon emission and measuring and calculating enterprise of textile production processing part.

Compared with prior art, the present invention the phenomenon that energy for textile enterprise is shared with material common scenario,
It proposes yield disassembly principle, public the dividing of input amount of enterprise when producing and processing is avoided because ignoring public portion during measuring and calculating
The problem of results of measuring is not comprehensive caused by the carbon emission divided, and numerical value is relatively low, and the carbon emission for calculating production section is basis
The electric power data and heating power data that the equipment that various textile production processing actually utilize is consumed, thus by cogeneration units
The carbon emission of power consumption and the carbon emission of heating power consumption calculate rather than carbon emission is simple respectively during to producing this kind of product
Being attributed to electric power, unilaterally consumption or heating power unilaterally consume generation, and results of measuring is more scientific and reasonable.
