welcome to @LiteFootPrints' forum:

➡️ living in the clean economy — the case for a faster transition

#CarolynIngvason, lighter footprints' indomitable convenor, is introducing the evening's programme…

(facebook live link to be posted soon — or follow on along on twitter👇)

@LiteFootPrints a great lineup this evening!

• @Tom_Kompas
• @PeterNewmanCUSP
• #AntheaHarris of @DELWP_Vic

if you have questions for the speakers, you can make them (or boost other's questions) through sli.do #7873.

(look, i get a credit! these guys are professionals!)

@LiteFootPrints @Tom_Kompas @PeterNewmanCUSP @DELWP_Vic great to be working alongside @VictoriaMcKMcH this evening.

victoria is a veteran climate communicator and very capable chair.

@LiteFootPrints @Tom_Kompas @PeterNewmanCUSP @DELWP_Vic @VictoriaMcKMcH dr. @Tom_Kompas up now.

➡️ where are we now?

we now have the tools to model the impact of climate change on the economy…

the modelling uses "damage functions" — effects on:
• loss of productivity
• sea level rise on land area
• human health effects

a small shift in temperature distributions results in a large increase in number of extreme temperature events…

…we can estimate the long-term *annual* GDP loss ($bn) for different warming scenarios.

…the cumulative losses are *massive*.

$604 trillion in 4°C scenario.

…the impacts are not uniformly distributed. equatorial countries are hit hardest.

…globally the average losses range from 3-10%, but some countries are hit much harder…

…australia's emissions are increasing.

…let's zoom in:

…we're making progress in energy, but a *long* way to go…

…so what's the damage in #australia?

$611bn in infrastructure damage alone through to 2050.

conservative estimates show $1.19tn in #ClimateChange damage to 2050 — over $6tn through to 2100.

…so what's the cost of action?

$145bn investment to avoid more than $1.19tn+ in damage.

should be an easy decision.

…cheaper to act than to do nothing.
…the earlier we start the cheaper it'll be.

summary: ACT NOW!

up now, #AntheaHarris, dep. sec. energy unit from #victoria @DELWP_Vic…

➡️ #victoria takes #ClimateChange seriously…

…victoria has an emissions reduction trajectory and is on track…

electricity generation is the largest share of victoria's emissions — by a long way.

…maximum temperatures could reach 50°C in #melbourne by 2050, with even higher temperatures inland, without emissions reduction…

…the #ClimateChangeAct, closely modelled on the UK framework, provides the framework for victoria to play its part in the solution.

interim targets are key, required by law.
gov't must commit to new target in early 2020.

…process for setting targets for 2025 and 2030 is well underway…

proposed targets from the #CombetReview:
• 2025: 32-39% reduction
• 2030: 45-60% reduction

…what's already happening…

legislated renewables targets:
• 25% by 2020
• 40% by 2025
• 50% by 2030

the #VRET will increase electricity volume, reduce bills, grow economy, create jobs, reduce emissions.

the @SolarVictoriaAU #SolarHomesProgram will put solar PV on another 700,000 rooftops, plus 60,000 solar hot water systems and 5,500 jobs.

…all tram travel in melbourne is offset by 100% renewable energy.

…saving 80,000t of CO₂ annually.

…the #VictorianEnergyUpgrades scheme just turned 10 years old and has saved victorians more than $3bn to date and reduced emissions by 52m tonnes so far.

…the quiet achiever!

…how about adaptation? projects underway:

next up… @PeterNewmanCUSP…

@PeterNewmanCUSP …we are learning how to decouple economic growth from greenhouse gas emissions…

great stat from the asian development bank:
over 10 years their funding allocated to roads has dropped from 91% to 45%.

…the decoupling is manageable.

it's clearly not fast enough, but progress is accelerating. this is how transitions happen.

three step model:

…5 big transitions over the past 250 years, and now into the 6th…

…in every transition we needed to dream of a more prosperous and equitable safe future…

a "secular faith".

…many visions of how we get there…

all are about... hope.

…australia is producing much of the material that make batteries.

8 lithium mines in WA!

…look at australia in the chart below — we have the goods.

…cities are vital to winning the battle.

• induction cooktop
• heatpump
• electric car
• solar

…payback in 9 years.

…when mainstreamed, the payback can be in 6 years or less.

…transport? electrify, electrify, electrify!

…biophilic urbanism…

…can we improve on the 1950s vision for suburbia? yes, says david holmgren.

…subscribe to @ReNewmagazine!

@ReNewmagazine …go watch @2040Film!

…join you local climate action group (like @LiteFootPrints)…

…*we* can do it!

question time. highlights:

@Tom_Kompas:
• why do we tax good things and subsidise bad things?
• how about a price on carbon!

.@PeterNewmanCUSP:
• export renewables as hydrogen, minerals, submarine cables

@Tom_Kompas
• emissions are still rising
• a function of economic growth

@PeterNewmanCUSP @Tom_Kompas .@PeterNewmanCUSP gives a shout out to climate activists everywhere — from @XRebellionAus to @LiteFootPrints and everything in between.

with very good summaries from @VictoriaMcKMcH and #CarolynInvarson, it's a wrap.

@PeterNewmanCUSP @Tom_Kompas @XRebellionAus @LiteFootPrints @VictoriaMcKMcH next @LiteFootPrints meeting — 27 november:

powering up summer!
• @dylanjmcconnell of @unimelb
• @brazzaleric of @GreenEnergyTrad

two of australia's leading experts — not to be missed.
