Climate change stem from increasing greenhouse gases such as carbon dioxide are the result of emissions from fossil fuel combustion, tropical land clearing and natural process. To offset those gases, CO2 emissions are being limited through engineering controls or storing carbon through biological controls. The concept of carbon credits came into existence as a result of increasing awareness of the need for controlling emission and formed under the “Kyoto Protocol” is an international agreement linked to the UNFCCC. To make the “Kyoto Protocol” more effective, the concept of Carbon Credits was introduced. Carbon Credit is like a Permit that allows an entity to emit a specified amount of greenhouse gases. One credit is equal to 1 tonne of CO2 reduced. It introduces a new form of commerce: the carbon trade is a new economic activity involves the buying and selling of “environmental services” including the removal of greenhouse gases from the atmosphere. Carbon credits are currently trading for $9.5 to $10 per metric ton. There are six exchanges trading in carbon allowances. JI and CDM are the two project-based mechanisms which feed the carbon market. Currently there are about 227 upcoming manufacturing/public utility projects in India whereas the global requirement is 350-500 million tons of additional carbon credits. Countries not only invest in new technologies & heavy machinery in order to reduce their emissions but they can just pay a minimal amount & get a carbon emission certificate for their emissions.

Amidinothiocarbamides and their derivatives possess various pharmaceutical, industrial, medicinal and agricultural values1-4. Intraction of different thiocarbamides and substituted cyanamides were carried out to synthesised respective substituted thiocarbamides, bis-foramidino sulphide, amidinothiocarbamides (salt) and their derivatives.5-8 Amidinothiocarbamides and their derivatives were successfully cyclised into respective Hector’s bases, thiadiazines, dithiazines, thiadiazolidines, s-triazines and pyrimidines by using different reagent and different reaction conditions. 9-14 So it was thought interesting to synthesis yet new series of 1,3-bis (Nsubstitutedamidinothiocarbamido)- thiocarbamides.(2) which may posses different pharmaceutical, industrial, medicinal, agricultural important which may be further cyclise to synthesis yet new series of 5 and 6 membered hetercyclic compounds.The structure of all these compounds were established on the basis of elemental analysis ,IR and PMR spectral data.

Density, speed of sound and viscosity have been measured for binary liquid mixture containing o-anisidine + amyl acetate over the entire composition range at temperatures 303.15, 308.15, 313.15 and 318.15 K and at atmospheric pressure. By using these values various parameters like adiabatic compressibility (β), free volume (V), free length (Lf), internal pressure (π) and their excess values have been calculated. The intermolecular interactions and structural effects are analyzed on the basis of the measured and derived properties.
