"Directive" means Directive 2003/87/EC of the European Parliament and of the Council of 13 October 2003 (OJ No. L275, 25 October 2003, p. 32) establishing a scheme for greenhouse gas emission allowance trading within the Community and amending Council Directive 96/61/EC of 24 September 1996 (OJ No. L257, 10 October 1996, p. 26);

"greenhouse gas emissions allowance" means—

(a) an allowance, permit, licence or right to emit during a specified period, a specified amount of carbon dioxide or any other greenhouse gas as defined in the Directive where such allowance, permit, licence or right is issued by a State or by an inter-governmental or supra-national institution pursuant to a scheme which—

(i) imposes limitations on the emission of such greenhouse gases, and

(ii) allows the transfer for value of such allowances, permits, licences or rights, or

(b) any right that is directly attributable to anything within paragraph (a).

(2) Subject to subsection (3), stamp duty shall not be chargeable under or by reference to any heading in Schedule 1 on an instrument for the sale, transfer or other disposition of a greenhouse gas emissions allowance.

(3) Where stamp duty is chargeable on an instrument under or by reference to any heading in Schedule 1 and part of the property concerned consists of a greenhouse gas emissions allowance—

(a) the consideration in respect of which stamp duty would otherwise be chargeable shall be apportioned, on such basis as is just and reasonable, as between the part of the property which consists of a greenhouse gas emissions allowance and the part which does not, and

(b) the instrument shall be chargeable only in respect of the consideration attributable to such of the property as is not a greenhouse gas emissions allowance.

(4) The amount or value of the consideration attributable to a greenhouse gas emissions allowance, shall be disregarded for the purposes of the statement provided for in paragraphs 7 to 14A of the heading "CONVEYANCE or TRANSFER on sale of any property other than stocks or marketable securities or a policy of insurance or a policy of life insurance" and any statement referred to in those paragraphs shall be construed accordingly.

(5) Where part of the property referred to in subsection (1) of section 45 consists of a greenhouse gas emissions allowance, that subsection shall have effect as if the words "in such manner as is just and reasonable" were substituted for "in such manner, as the parties think fit".

(6) Where part of the property referred to in subsection (3) of section 45 consists of a greenhouse gas emissions allowance and both or, as the case may be, all the relevant persons are connected with one another, that subsection shall have effect as if the words ", the consideration shall be apportioned in such manner as is just and reasonable, so that a distinct consideration for each separate part or parcel is set forth in the conveyance relating to such separate part or parcel, and such conveyance shall be charged with ad valorem duty in respect of such distinct consideration" were substituted for "for distinct parts of the consideration, then the conveyance of each separate part or parcel shall be charged with ad valorem duty in respect of the distinct part of the consideration specified in the conveyance".

(7) For the purposes of subsection (6), a person is a relevant person if that person is a person by or for whom the property is contracted to be purchased and the question of whether persons are connected with one another shall be construed in accordance with section 10 of the Taxes Consolidation Act 1997 and as if the reference to the Capital Gains Tax Acts in the definition of "relative" in that section was replaced by a reference to the Stamp Duties Consolidation Act 1999.

(8) Where subsection (5) or (6) applies, and the consideration is apportioned in a manner that is not just and reasonable, the conveyance relating to the separate part or parcel of property shall be chargeable with ad valorem duty as if the value of that separate part or parcel of property were substituted for the distinct consideration set forth in that conveyance.
