Carbon Performance Clauses

Jessica's Clause

Include climate metrics for performance in all contracts. Provide a mechanism akin to liquidated damages for breaches with negative climate impacts, in the form of mandatory donations to non-profits.

Skip to clause

Why use this?

Currently the carbon costs of producing goods or delivering services are not usually specified in contracts and, therefore, there is no incentive to reduce carbon emissions.

Here, the supplier warrants it will meet certain targets for the climate and environmental impacts of delivering the goods or services under the agreement. If breached, the supplier must pay a climate remediation fee to a selected environmental charity.

How it promotes a net zero future

Cascading environmental clauses which provide a remedy for breaches that impact a purchaser’s GHG targets - and therefore cause negative climate impacts - should increase the speed of transition to net zero.

The clause


[Note: Agreement to contain recital below in addition to the other recitals relevant to the Agreement. The recital below should be viewed as a starting point for a sustainability recital. Expanding the Recital to address and memorialise sustainability commitments should be considered.] 

The parties acknowledge that the performance of this Agreement will result in certain climate [and ecological] impacts, including the emission of greenhouse gases.

1. Climate and Ecological Impacts Under this Agreement

Each party agrees to use all reasonable endeavours, and cooperate in good faith with the other party and its contractors, to minimise as far as reasonably practicable the quantity of greenhouse gas emissions related to this Agreement.

2. Climate Reporting and Warranties

[Note: The parties should agree a mechanism for measuring their climate and environmental impacts under this Agreement. The warranties below should be adjusted accordingly. These could also be used as warranties in M&A transaction documents.]

2.1 The Supplier agrees to:

2.1.1 provide the first Annual Emissions Report within [twelve (12)] months after the start date of this Agreement and each other Annual Emissions Report no later than forty (40) Business Days after the applicable Emissions Report Date; [and]

2.1.2 measure and calculate its Total Emissions in accordance with the GHG Reporting Standard[, and ensure that they are verified each year by an Independent Third Party before being provided to the Customer]*; [and]

2.1.3 [insert other climate performance metric as relevant to the performance of this Agreement].

2.2 The Supplier represents and warrants that:

2.2.1 all Annual Emissions Reports provided to the Customer are in all material respects complete, accurate and not misleading; and

2.2.2. it will not commit any Climate Breach during the term of the Agreement.

[*Note in relation to 2.1.2: Before including third party verification requirement, determine if appropriate for the supplier in question in light of the supplier’s size.]

3. Climate Remediation Fee

3.1 Without prejudice to any other claims, rights or remedies under this Agreement, the parties agree that, in respect of any breach of the warranties set out in clause 2.2, damages payable by the Supplier to the Customer would not be an appropriate remedy in the wider context of damage to the climate, the environment and the Customer’s reputation (all of which the Supplier accepts for the purpose of this Agreement as being losses incurred by the Customer). Without prejudice to the Customer’s right to damages, the Supplier agrees to pay the Climate Remediation Fee as set out in this clause 3.

3.2 The parties agree that any Climate Remediation Fee payable under this Agreement to provide compensation for damage caused by the Supplier’s Climate Breach is reasonable and proportionate to the legitimate interests of the Customer in mitigating, setting off, counteracting, and repairing that damage (and preventing future damage), in part reflecting its public commitments to [reduce greenhouse gas emissions]. Each Party agrees that it has been properly advised regarding the negotiation of this Agreement, and in particular regarding the inclusion of the Climate Remediation Fee as a remedy for Climate Breaches.

3.3 If the Customer identifies or suspects a Climate Breach the Customer may serve a Climate Remediation Notice on the Supplier at any time within twenty (20) Business Days of [the occurrence of such breach / becoming aware of such breach], whichever is later.

3.4 Upon receipt of a Climate Remediation Notice, the Supplier will promptly investigate the matter and if the Supplier is unable to mitigate the relevant Climate Breach to the Customer’s reasonable satisfaction within thirty (30) Business Days of receipt of the notice pay the applicable Climate Remediation Fee to the Appointed Beneficiary within fifteen (15) Business Days of the Supplier’s failure to cure the relevant Climate Breach.

(iii) any other material breach of Clause 2;

Climate Remediation Fee” means:

(i) in respect of clause (i) of the definition of Climate Breach, an amount equal to the cost of carbon credits that must be purchased to offset each metric ton of CO2e that Total Emissions exceed the Emissions Reduction Target; and
