Climate change policy approach
City’s climate change policy approach
work differently &
collaboratively

City’s climate change policy approach cont.
Contribute to global efforts to
reduce GHG emissions
Prepare for change at local level to
reduce risks & build adaptive
capacity

21
How do we fundamentally change how we work to catalyse action at scale and
with urgency? i.e. transformative change
People Technology / approaches
Finance Networks
MIND THE GAP
People: We all view the world with different lenses
22
Which word do you see 1st?
Have to make the time to understand others’ challenges & collectively find solutions
People: Understanding uncertainty
23
Is climate change real?
Timing of change – when?
Magnitude of change – how big?
Change in frequency – how often?
Rather
Use of scenario planning & narratives
People: Managing in the face of uncertainty
24
Understand change management
Build networks & relationships
Access technical support
Cost benefit analyses – LT approach
Examples from elsewhere – networks
Resilience = good development
Technology & approaches
Untested vs. tested
Financial management frameworks
Fear of white elephants
Life cycle costing
Retrofit vs. replace when obsolete
Finance: City budgets

Finance: City budgets cont.
City budget
City budget
Vs.
Finance - options
preventative vs reactive ?
buffer to absorb shocks
spending to save?
what tradeoffs?
who has what mandate / responsibility?
how to prioritise?
Upfront questions:
use of existing budgets (City and National): more
efficient, reshuffle
changes informed by CBA and policy alignment
external funding – reveune, grants, loans,
green bonds
Networks – City co-dependent
Risks
Adaptive capacity
Strengths / mandates
Roles
Business
Civil society
Academia
NGOs
Other spheres of government
Industry
Educators
Closing the gap
1. Bring everyone along 2. Enable innovation 3. Develop & use alternative forms of
financing 4. Only possible in collaboration with
others
