ok @DaveSharma i promised i'd explain why your tweet is nonsense & why you shouldn't repeat it.

👇here's #australia vs #newzealand relative emissions since 2005:
• australia ⬆️ 6%
• new zealand ⬇️ 3%

(you'll notice that LULUCF is excluded…)
why is LULUCF (land-use, land-use change & forestry) excluded?

1. measurement methodologies aren't standard between countries & frequently change — no robust method to compare countries
2. annual fluctuations are high / noisy

data: PRIMAP-hist v2.1
pik-potsdam.de/paris-reality-…
3. the vast majority of australia's LULUCF variation is driven by changes to QLD land-clearing laws, a function of state political tussles, and nothing to do with commonwealth policy.
4. australia is famous for using LULUCF as a fudge, see @MichaelM_ACT:

don't get me wrong, NZ is no climate-angel… the kiwis have a long way to go.

…disappointingly their emissions have only fallen a little since 2005.

…shamefully, we have significantly increased ours — thanks #LNG / fossil gas!
…and while #australia is slowly reducing its per capita emissions intensity, #NZ's have never been as high as ours are now.

at this rate it'll take us _forever_ to get down to their historical peak!
…again, NZ is no climate angel, but while australia practically tied with #trump's USA for *last* place in the recent climate change performance index on policy, #NZ finished in the top third.

NZ: needs to do better.
AUS: fail!

…at least NZ has a *legislated* net-zero target.

…and sure, NZ's target isn't perfect, but we:
• have a crap 2030 target
• don't have a net-zero target
• have a gov't that routinely lies about this stuff
• are on track for net-zero by 2294: 🙀
.@DaveSharma there's a fair chance you're going to be around for a while.

you're smart & i suspect you care.

you also come from a savvy electorate.

be honest with them… don't lie & you'll earn respect.

but if you lie like angus🤥, you'll end up with as much respect as angus.

🧵 many #nuclear hopes are riding on small modular reactors.

@NuScale_Power's #SMR is closest to market. customer for pilot plant is a group of utilities, herded by @SmartEnergy1.

in july only 213 of 720MW (30%) was subscribed.
subscriptions have since dropped to 104MW (14%)…
of the 36 towns in #nuscale's pilot project, the "carbon free power project" #CFPP:
• 8 towns have withdrawn entirely
• 24 reduced their share entitlement
• 3 maintained identical entitlement
• 1 joined (token level).

utah.gov/pmn/files/6554…
with the planned 12 module plant undersubscribed, #nuscale is now looking at downsizing to either 4 or 6 modules.

counteracting this fall of subscriptions, nuscale has uprated modules from 60MWe to 77MWe each.

as such, nuscale now has 33% subscriptions for a 4 module plant…

🤓 gather round for a little yarn about #australia's remarkable, accelerating energy transition. 🧵

just 3 years ago #AlanFinkel @ScienceChiefAu was tasked to review the national electricity market (NEM).

he recommended that AEMO prepare an #IntegratedSystemPlan every 2 years.
the #ISP has 5 core scenarios…

don't think of a scenario as a prediction, but rather a set of constraints/assumptions and the cheapest path found to supply power within those constraints.

let's talk about the 'step change' scenario.
'step change' is the closest to being compliant with the paris agreement — ie. a half-decent start if we want to keep the great barrier reef, not destroy civilisation etc.

it gets us to 96% renewables in 2042.

(the central 'business as usual' scenario is a few years slower.)

🧵the sloppy advocacy of #nuclear zealots

earlier this year adelaide-based nuclear lobby group @BNW_Aus submitted this chart (sans emoji) to the #victorian parliamentary inquiry into #nuclear prohibition.

one problem: it’s 🐂💩!
.@BNW_Aus claims to be an environment group, yet *all* they seem to do is fight against australia’s nuclear bans.

i’ve no problem with nuclear advocacy — nuclear technology is pretty amazing & we should keep our minds open — but why not just be honest & admit your sole purpose?
the chart aims to show that nuclear is awesome because it’s just so thrifty.

BNW's GM @dayne_eckermann says it’s relevant because “you need materials mined from the ground to make things. it's better if we limit that as much as possible to protect the environment”.

fair enough.

angus starts by talking up the role of technology in civilisation… as if this is new.
apparently snowy hydro is an example of home grown technology. hmmmm.
