Option 1 (Organisation)
Net Negative is a state where Scope 1, 2 and 3 Greenhouse Gases [sequestered] [removed from the atmosphere] [absorbed by the [processes] [activities]] [of [name of party]] are greater than the Scope 1,2 and 3 Greenhouse Gases emitted [by [name of party]].
Option 2 (Product)
Net Negative is a state where there is a net [sequestration] [removal] [absorption] effect from either production or total lifecycle impact of a product leading to negative Scope 1, 2 and 3 Greenhouse Gas Emissions.
Net Negative means that the aggregate of [a party’s] [the Company’s] actions to reduce its GHG Emissions and remove them from the atmosphere exceeds its unabated GHG Emissions.
Option 4 (Activity/ Technology)
For All Options
The amount of Scope 1, 2 and 3 Greenhouse Gases [sequestered] [removed from the atmosphere] [absorbed by the [processes] [activities]] must be measured using a standardized method of measuring and quantification to be agreed between the parties.
Net Negative Amount
Net Negative Amount means the amount to be paid by the [party/ies] where Net Negative is achieved by [date].
Several drafting options are included as the term “Carbon Negative” or “Net Negative” is currently not widely used. The term “Net Negative” is used to ensure that all greenhouse gases, and not just carbon dioxide, are covered in the definition.
There is not yet an agreed methodology for calculating if a product or activity is Net Negative in the same way as there is for Carbon Neutral. Which definition to use will depend on the subject and purpose of the clause being drafted. Issues to consider include:
- Are you requiring an entity to be Net Negative?
- Is an entity committing to be Net Negative?
- Do you require an entity to only use Net Negative technology or to produce a Net Negative product?
On a global scale, removals of Greenhouse Gases should be consistent with the mitigation pathways that would limit global warming to 1.5°C, with little to no overshoot. See IPCC Special Report on Global Warming of 1.5 ºC, Summary for Policymakers, Part C Emission Pathways and System Transitions Consistent with 1.5°C Global Warming.
The technology or activity used to remove Greenhouse Gases from the atmosphere must have a degree of permanence. Protocols or rules relevant to the area and project also need to be developed and documented to ensure the quality of removals. Reliable and independent auditors should validate and verify the measurements.
Note that the term “Carbon Positive” is used by some organisations instead of Carbon Negative to avoid the use of the word negative when describing their work to reduce their GHG emissions.
Supply chain clauses, national climate laws, green leases (where the premises being leased are to be carbon negative), project finance documents (e.g. loan, guarantee and recourse agreements, engineering, procurement and construction contracts), policy documents.
