Evelyn and Ezra's Clause

Securing Net Zero in Planning Development Projects

Drafting resources to help local planning authorities gain confidence in requiring carbon neutral development as standard in their areas through policy, planning conditions and obligations. 

Jurisdiction: England & Wales

What this clause does

This clause helps infuse planning decisions with net zero and climate aligned considerations in order to incorporate sustainable practices and principles into development projects from an early stage of the project.


Mechanisms, suggested drafting solutions and resources

  1. Planning policy examples
  2. Planning obligation to secure a sustainability plan
  3. Planning condition or obligation to secure net zero development
  4. Whole lifecycle carbon assessments
  5. ‘Be Seen’ energy monitoring
  6. Carbon offset funds and planning obligations securing carbon offset contributions

1. Planning policy examples

Draft London Plan (draft (Intend to Publish) version Dec 2019) contains policy SI 2 Minimising greenhouse gas emissions (p414), which states major developments should be net zero-carbon in operation, follow the energy hierarchy (be lean, be clean, be green, be seen), include a detailed energy strategy, reduce beyond building regulations and if zero carbon cannot be met on site, provide offsite mitigation or a cash in lieu contribution. Requirement for certain development proposals to provide a whole life-cycle carbon emissions assessment (see point 4 below).

2. Planning obligation to secure a sustainability plan 

The Owner agrees:

1) Prior to Commencement of the Development, to agree the Sustainability Plan with the Local Planning Authority and appoint a nominated Sustainability Plan Coordinator(s) and notify the details of the Sustainability Plan Coordinator(s) to the Local Planning Authority.

2) To comply with the terms of the Sustainability Plan throughout the lifetime of the Development PROVIDED THAT any failure on the part of the Developer to comply with this provision which is due to acts, events or other circumstances beyond the reasonable control of the Developer shall not constitute a breach of this Agreement.

3) Not to allow Occupation of the 1st Dwelling on the Land until the Sustainability Plan Monitoring Fee has been paid to the Local Planning Authority.

4) Developers shall review the Sustainability Plan in accordance with the provisions of and timescales set out in the Sustainability Plan and to submit the results of such review(s) to the Local Planning Authority.

5) Following discussions with the Local Planning Authority, the Developer shall have regard to any reasonable recommendations made by the Local Planning Authority in relation to each review and incorporate, where reasonable, such recommendations.

3. Planning condition or obligation to secure net zero development [adapting Rory’s Clause and related definitions]

The Developer agrees:

3.1 Prior to commencement, to submit to the Local Planning Authority a plan to achieve all of the Net Zero Objectives (Net Zero Objectives Plan).

3.2 Not to Commence Development before the Local Planning Authority has approved the Net Zero Objectives Plan.

3.3 To comply with the Net Zero Objectives Plan subject to any amendments agreed in writing between the Local Planning Authority and the Developer.

4. Whole Life-Cycle Carbon assessments

‘Whole Life-Cycle Carbon (WLC) emissions are the carbon emissions resulting from the materials, construction and the use of a building over its entire life, including its demolition and disposal. A WLC assessment provides a true picture of a building’s carbon impact on the environment.’

5. ‘Be Seen’ energy monitoring

Monitoring of a development’s energy use during the first years of its life. This is to help understand (and reduce) the gap between a development’s theoretical energy use and its actual operational energy use.

6. Carbon offset funds and planning obligations securing carbon offset contributions

For guidance on how to set up a carbon offset fund and how the funds may be spent, see: Carbon Offset Funds, Greater London Authority guidance for London’s Local Planning Authorities on establishing carbon offset funds, Mayor of London, October 2018, available here (as at 28 July 2020).


Carbon Capture means the [technology for and] process of capturing, transporting and storing waste carbon dioxide.

Carbon Offset Contribution means the sum to be calculated in accordance with the Carbon Offset Contribution Formula as taken from the Local Planning Authority’s [insert Supplementary Planning Document reference] towards the provision of carbon offsetting projects within the Local Planning Authority’s administrative area.

[Example] Carbon Offset Contribution Formula means the following formula:

(a) x (b) x (c) 


(a) = carbon gap (residual tonnes of carbon)

(b) = price of carbon (£)

(c) = 30 years

Carbon Offsetting means the purchase of a quantity of carbon credits equal to the amount of Residual Emissions from a project that has been verified in accordance with [insert name of voluntary standard] or from a United Nations Framework Convention on Climate Change (UNFCCC) clean development mechanism (CDM) [or [successor/ equivalent] UNFCCC mechanism] project.

District Heating Scheme means a new or existing system for the distribution of heat and hot water to buildings on the Development.

Embodied Carbon means the Greenhouse Gases that are emitted through the production and delivery of building materials for and used in the Development.

EV means a vehicle that uses one or more electric motors for propulsion and obtains all its power from an electric battery.

EV Parking Spaces means spaces specifically designated for charging EVs through charge points or directly from the grid.

EV Substation Capacity means a substation with sufficient capacity to be able support the requirements of the EV Parking Spaces.

Greenhouse Gas (GHG) means gases that contribute to or accelerate the greenhouse effect by absorbing infrared radiation, including but not limited to: carbon dioxide, methane, nitrous oxide, sulphur hexafluoride, hydrofluorocarbons, perfluorocarbons and chlorofluorocarbons.

Hydrocarbons means principally oil, gas and coal or other fuel source derived from an organic compound made up of hydrogen and carbon.

Net Zero Objectives means obligations to:

a) maximise the proportion of Zero Carbon Housing on the Development;

b) use building materials with the lowest Embodied Carbon reasonably available;

c) maximise self-generation of renewable energy on the Development;

d) minimise the use of heating and hot water technologies that use Hydrocarbon fuels or produce Greenhouse Gases;

e) establish a Community Energy Programme to supply renewable energy to the Development;

f) maximise Carbon Capture at the Development;

g) use Carbon Offsetting for the Development as a last resort;

h) minimise the use of energy by the Development using ‘smart grid’, demand side energy management and other technologies;

i) prioritise the use of electricity from renewable energy sources over all other types of fuel on the Development;

Sustainability Plan means a plan to be agreed in writing with the Local Planning Authority which sets objectives to ensure the Development is constructed and maintained for the lifetime of the Development in a way that is sustainable (in accordance with paragraph 8 of the National Planning Policy Framework (as amended from time to time)) and where appropriate shall impose obligations on the Developer including (but not limited to) the following:

a) a recommendation for the Developer and any future landlords of the Development to use the most detailed version of the sustainable obligations set out in Schedule 6 of the Model Commercial Lease;

b) an obligation to monitor the usage of electric car charging points in any public/ common parking areas and to submit an annual report to the Local Planning Authority on the usage of the electric car charging points. Where the usage of the electric car charging points exceeds X hours per month, an obligation to provide additional electric car charging points to meet demand;

c) an obligation where possible to use renewable energy through on-site energy sources (such as solar or wind) or where it is not possible to use on-site renewable energy sources, an obligation to source renewable energy from energy suppliers;

d) an annual requirement to publish in the public domain 5-10 initiatives which are being promoted at the Property that support sustainable development (in accordance with paragraph 8 of the National Planning Policy Framework);
