A formal ‘carbon budget’ alongside the traditional financial budget for construction projects, to incentivise industry participants to reduce GHG emissions through use of more sustainable materials.
Why use this?
To set a carbon budget for construction projects governed by JCT Design & Build Contract 2016 and reduce greenhouse gas emissions by incentivising parties to adopt more sustainable practices and materials.

Carbon Budget means the aggregate of [value] tonnes of Carbon Dioxide Equivalent of Greenhouse Gas Emissions permitted for the construction of the Works as set out in Appendix [X].
Carbon Offsetting means the purchase of a quantity of carbon credits equal to the amount of the Residual Emissions from the Works that has been verified in accordance with [insert name of voluntary standard].
Carbon Dioxide Equivalent (CO2e or CO2eq) means a unit of measurement that is used to standardise the climate effects of various Greenhouse Gases.
Greenhouse Gases (“GHG” or “GHGs”) means the natural and anthropogenic gases which trap thermal radiation in the earth’s atmosphere and as specified in Annex A to the Kyoto Protocol to the United Nations Framework Convention on Climate Change (UNFCCC) or otherwise specified by the UNFCCC, and which currently include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3).
Greenhouse Gas Emissions (“GHG Emissions”) means emissions of Greenhouse Gases over a specified area and period of time, each expressed as a total in units of carbon dioxide equivalent (CO2e) [and calculated in accordance with the GHG Protocol Corporate Accounting and Reporting Standard or such other equivalent and generally recognised greenhouse gas emission calculation methodology].
Prohibited Materials means any material, substance, product, process, technique or combination of the same which, by its nature or application:
.1 contravenes any British Standard or EU equivalent;
.2 contravenes the recommendations of the British Council for Offices’ publication Good Practice in the Selection of Construction Materials (2011) (as may be amended or updated from time to time);
.3 would unnecessarily increase the total GHG Emissions of the Works because their embodied GHG Emissions cannot be reduced by Carbon Offsetting; or there is an alternative material or good which meets the standards of the Contract with fewer embodied GHG Emissions; or
.4 is generally considered to be deleterious or harmful to the environment within the building design professions.*
* [Drafting note: While this definition is not used in this clause, the term it is used in the JCT D&B Contract and should be amended accordingly so other contractual provisions support this clause.]
Residual Emissions means the Greenhouse Gas Emissions that are emitted after all reasonable efforts have been made to reduce emissions.
Additional Clauses for use with JCT Design & Build Contract 2016
Climate Impact of Materials
2.1A.1 The Contractor shall provide to the Employer as soon as possible, but in any event within ten (10) days of such a request being made, all information that the Employer reasonably requests regarding the climate impacts, including the total embodied GHG Emissions, of the supply and use of materials and goods which are selected or used in carrying out the Works.
2.1A.2 The Contractor confirms that the total embodied GHG Emissions in the materials and goods used to construct the Works and GHG Emissions emitted in the construction of the Works shall not exceed the Carbon Budget.
2.1A.3 In selecting materials and goods for use in the Works, the Contractor shall:
.1 prior to the commencement of the Works, provide a list of the intended manufacturers and suppliers to the Employer’s Agent along with the climate impacts of the transportation of the same to the Site as against the Carbon Budget;
.2 liaise with the Employer’s Agent with regards to the list of intended manufacturers and suppliers and shall have due regard to the representations of the Employer’s Agent with regards to the same;
.3 [use best endeavours to ensure that the materials and goods are sourced from manufacturers and suppliers located as close to the Site as reasonably practicable;]
.4 update the Employer’s Agent, on a monthly basis, with the actual climate impacts of the transportation of the materials and goods to the Site to date by reference to the levels set out in the list and the projected impact of the same for the remainder of the Works assessed against the Carbon Budget.
2.1A.4 If the Carbon Budget of the Works (excluding Changes issued in accordance with clause 3.9.1) is exceeded due to a breach by the Contractor of its obligations under this [Clause: Climate Impact of Materials], then liquidated damages at the rate of £[X] per tonne of Carbon Dioxide Equivalent of Greenhouse Gas over and above the Carbon Budget, shall be due and payable from the Contractor to the Employer. To avoid doubt, liquidated damages payable under this [Clause 4] represent the reasonable commercial concerns of the Employer and its costs of [offsetting the excess GHG Emissions/ remedying an equivalent breach of the development funding agreement].
2.1A.1 The Contractor is required to carry out the Works so that the Carbon Budget is not exceeded.
2.1A.2 The Contractor is required to provide monthly management information on its ongoing compliance with [Clause 1] to enable the Employer to assess the progress of the Works towards meeting the Carbon Budget and provide input to the Contractor on further progress.
2.1A.3 If the Carbon Budget of the Works (excluding Changes issued in accordance with clause 3.9.1) is exceeded due to a breach by the Contractor of its obligations under this [Clause 3], then liquidated damages at the rate of £[X] per tonne of Carbon Dioxide Equivalent of Greenhouse Gas over and above the Carbon Budget, shall be due and payable from the Contractor to the Employer. To avoid doubt, liquidated damages payable under this [Clause 3] represent the reasonable commercial concerns of the Employer and its costs of [offsetting the excess GHG Emissions/ remedying an equivalent breach of the development funding agreement].
