Appendix: Actions in the low carbon pathway

The low carbon pathway consists of 25 actions, each with its own target:

Table A1: Actions in the low-carbon pathway

Action

Description

 

BUILDINGS

 

New buildings

1

Incrementally increase the number of net zero new homes to 100% by 2030.

2

Incrementally increase the number of non-residential buildings that achieve Passive House levels of performance to 100% by 2030.

 

Existing buildings

3

Retrofit 98% of pre-1980 dwellings by 2050, with retrofits achieving thermal and electrical savings of 50%.

4

Retrofit 98% of dwellings built between 1980-2017 by 2050, with retrofits achieving average thermal and electrical savings of 50%.

5

Retrofit 98% of pre-2017 industrial, commercial, and institutional buildings by 2050, with retrofits achieving average thermal and electrical savings of 50%.

6

Every building will be recommissioned on a ten-year cycle, achieving energy savings of 15% on pre-2017 building stock.

 

ENERGY SYSTEM

7

Air source heat pumps are added to 50% of residential buildings and 30% of commercial buildings by 2050. Ground source heat pumps are added to 20% of residential and 40% of commercial buildings by 2050.

8

Solar photovoltaic (PV) systems are installed on 80% of all buildings by 2050. These PV systems provide on average 30% of consumption for building electrical load for less than 5 storeys and 10% for multi-unit buildings greater than 5 storeys and commercial buildings.

9

Heat pumps for hot water installations are scaled up to 80% of residential buildings by 2050, and 50% of commercial buildings by 2050.

10

20 megawatts (MW) of commercial scale ground mounted solar PV is installed per year between 2018 and 2050.

11

A 16 MW seasonal storage district energy system is installed in the downtown area.

12

67 MW of energy storage is installed by 2050 to reduce the curtailment of the ground-mounted PV.

13

50 MW of wind energy is installed by 2050 outside of city limits.

14

Local production is maximised, and additional renewable natural gas is imported to displace natural gas consumption in buildings.

15

100 kilowatts of run of river hydro electricity generation is added.

 

TRANSPORTATION

16

Transit is introduced in areas with high density and insufficient transit.

17

The transit fleet is fully electrified by 2050.

18

The cycling and walking mode share is increased.

19

The percentage of trips that are rideshare is doubled by 2050.

20

A car-free downtown is created by 2040.

21

The municipal fleet is electrified by 2050.

22

100% of new passenger vehicles are electric by 2030.

23

95% commercial vehicles are electric by in 2030.

24

100% of new vehicles are autonomous by 2035.

 

INDUSTRY

25

The efficiency of process motors is increased by 50% by 2050.
