Climate Risk Sharing Provisions

Iris' Clause

Amendments and additions to standard Force Majeure agreements to ensure contracting parties work together to balance financial risks and avoid unintended adverse environmental and social issues.

Skip to clause

Why use this?

Contracting parties will not want to take the risk of known and foreseeable events such as global pandemics and climate change.

This clause has been drafted for a supply contract. However, the principles of “Climate Risk Sharing” can be applied to a variety of contractual agreements.

In effect this creates an orderly transition to a new normal for contractual risk assessment based on balancing financial obligations and the environmental and social impact.

How it promotes a net zero future

The proposed clauses will ensure that the parties take a fair share of risk. This should:

- make the supply chain more resilient as it enables both parties to stay in business and pay staff if impacted;

- make transactions work in the new context;

- give certainty to what would happen if climate change impacts affect a counterparty; and

- ensure that if parties are affected by Force Majeure events, they work together to minimise the impact on the climate and the environment.

Additional Definitions 

Adverse Climate Outcome (ACO): where non-performance of an affected obligation, or the enforcement of this clause [FORCE MAJEURE] in relation to that non-performance, directly leads to:

a) reduced air quality;

b) an increase in Greenhouse Gas Emissions;

c) dumping of stock that was created using natural capital;

d) wasted Embedded Carbon; or


Adverse Social Outcome (ASO): where non-performance of an affected obligation, or the enforcement of this clause [FORCE MAJEURE] in relation to that non-performance, directly leads to:

a) the insolvency of a party;

b) redundancies over and above [x];

c) an increase in poverty, deprivation or hunger; or

Climate Risk Sharing

  1. Climate Risk Co-operation

1.1 The parties agree and acknowledge that this Agreement is of significant commercial value to each of the parties and that neither party should bear the entire risk of a Climate Change Event or Pandemic occurring.

1.2 If a party is prevented from performing its obligations under this Agreement due to a Climate Change Event or Pandemic, the party shall as soon as reasonably practicable after the start of the Period of Disruption [or earlier date], notify the other party and provide a reasonably detailed summary of:

(a) Its understanding of the existence, location and nature of the Climate Change Event or Pandemic; and

(b) how the Climate Change Event or Pandemic has prevented and will continue to prevent it from performing its obligations under the agreement.

1.3 If a party gives notice under clause 1.2, the parties will work together, in good faith, [using reasonable efforts] to [promptly]:

(a) prevent the occurrence, or minimise the impacts, of any related ACO or ASO;

(b) ensure that each party’s Disruption Liquidity Ratio is maintained in accordance with clause 2;

(c) mitigate wasted Embedded Carbon in accordance with clause 3; and

(d) mitigate the effects of the Climate Change Event or Pandemic on performance of this Agreement and reduce the Period of Disruption, in each case to the extent it is safe to do so and will not cause an ACO or ASO.

  1. Maintaining Climate Liquidity Ratios to avoid ASO

2.1 During the Period of Disruption, the parties will prepare weekly Disruption Liquidity Ratios [on an open book basis OR supported by reports of independent accountants] (in the format set out in this Agreement or otherwise agreed by the parties in writing) and share these with the other party. [no later than the last business day of the applicable week.]

2.2 If a party’s Disruption Liquidity Ratio is less that [X], the parties’ Finance Directors shall discuss in good faith an amendment to the payment terms under this agreement by a reasonable additional period (up to a maximum of [NUMBER] days) to assist each party to maintain an Operating Cash Flow sufficient to meet its Current Liabilities and therefore avoid any ASO that could be caused by cash flow problems.

2.3 If a party does not to provide its Disruption Liquidity Ratio in accordance with clause 2.1, that party is deemed to have a Disruption Liquidity Ratio above the figure stated in clause 2.2.

  1. Carbon mitigation to avoid ACO

3.1 In the event of a Climate Change Event or Pandemic, the parties acknowledge that the Embedded Carbon in the [Products/Services] might be wasted where the [Products/Services] are manufactured but not delivered, or delivered but not used.

3.2 To avoid an ACO from wasted Embedded Carbon resulting from a Climate Change Event or Pandemic, either party may by written notice to the other party request that it:

(a) stops providing the affected [Products/Services] during the Period of Disruption without terminating this agreement;

(b) offers to sell the affected [Products/Services] to other customers and provide a corresponding payment discount to the notifying party; or

(c) reuse, resell or recycle the [Products or their constituent parts OR the input materials allocated to the Services] and provide a corresponding payment discount to the notifying party; or

(d) donate the [Products or their constituent parts OR the input materials allocated to the Services] to an agreed community project, social enterprise or other charitable cause.

3.3 If a party receives a notice under clause 3.2, it will consider the request in that notice within [NUMBER] days and shall only reject the request to the extent that:

(a) it will have a materially disproportionate effect on that party compared to comparable businesses in its sector; or

(b) other steps can be taken to avoid the ACO from wasted Embedded Carbon.
