3 The direct emissions of work-related travel on Church business will be included, but this is not subject to faculty jurisdiction. Matters that are not proposed to be in scope at present but may be brought into scope at some point before 2030 are wider and also not subject to faculty jurisdiction, such as emissions from farming and management of Church lands, upstream emissions from items purchased and downstream emissions from waste disposal, and emissions from email use and data storage and from Church investments other than those controlled by the Church Commissioners, who have their own ethical and environmental investment policies.

8 Re St Paul, Addlestone [2020] ECC Gui 1.

9 The case Re St Alkmund, Duffield [2013] Fam 158, a decision by the Court of the Arches, sets out the authoritative test that chancellors must apply when considering proposed changes to church buildings.

10 In a suitable case, other ‘environmental’ public benefits such as clean air from electric-vehicle charging posts, biodiversity from tree planting and locally grown food may also be relevant, as well as carbon emissions reduction.

11 Re St Mary, Moseley [2011] Cardinal Ch (Birmingham).

12 For example, Gloucester DAC have published a sustainability policy and their sustainability adviser offers free advice to churches. See <https://www.gloucester.anglican.org/wp-content/uploads/2020/02/DAC-Environmental-Policy-2020.pdf>, accessed 20 October 2020.

13 Usually an architect or buildings surveyor. ‘Quinquennial inspector’ is used as a shorthand hereafter.

14 Specialist advice must be taken if considering insulation of historic buildings to ensure that the proposals do not cause additional problems, particularly with damp.

15 By encouraging the preparation for change to take place before the boiler breaks, and perhaps by having a supply of plug-in electric heaters or heated cushions to lend out in emergencies. Emergency faculties may be obtained very quickly once the replacement is identified.

16 For example, the Royal Institute of British Architects declared a climate emergency in June 2019 and committed to developing an Ethics and Sustainable Development Action Plan, so is likely to be in a position to assist in this regard.

17 The Heat Policy Commission Report from the Confederation of British Industry, Net-Zero: the road to low-carbon heat, July 2020, has made wide-ranging recommendations, including:

1. i.

   i. A government-mandated, phased switchover from existing natural gas boilers to other solutions like heat pumps and hydrogen technologies, including heat networks;

2. ii.

   ii. From 2023 no new domestic oil-fired boilers to be installed;

3. iii.

   iii. After 2025 all new domestic boiler installations to be part of a hybrid system or be ‘hydrogen-ready’;

4. iv.

   iv. From 2035 all new heating installations to be low-carbon. No new natural-gas-burning boilers or systems should be installed and only net-zero compatible technologies like air-source or ground-source heat pumps, hydrogen-burning boilers or heat networks should be deployed.

18 A sapling will obviously remove far less carbon from the atmosphere than a mature tree for many years after it is planted, and therefore consideration of the adequacy of the replacement tree(s) must be considered. Chancellors, too, need to be more aware of the carbon emissions reduction significance of the removal of mature trees. Two faculties to remove trees have been recently granted without any apparent assessment of the carbon reduction lost by removing these trees or any condition of others being planted. See Re All Saints, Marcham [2020] ECC Oxf 1 and Re St Mary, Chithurst [2020] ECC Chi 1.

19 In Re St Michael and All Angels, Blackheath Park [2020] ECC Swk 1, a faculty for floodlighting was granted on the basis that that it would be powered by electricity from a renewable source.
