They'll probably be silent today as the #IPCCReport is released.

But expect them to raise their voices over the next few weeks & months. The 12 types of climate delayers - learn to know them ⬇️

I said they'll be silent today but I have to correct myself - not these two, they won't

If you know Germany you know that it's pretty common, almost 'common sense', to claim that Germany is doing better than other countries re: climate & environment.

Journalist here calls it an "undisputed climate leader"

But how much truth there is to it?

THREAD with figures
I use figures from EEA for greenhouse gas emissions per capita in various sectors for 2019

I compare DE with other large EU countries + UK, as well as the EU+UK average

I use per capita figures because DE is larger than other countries
eea.europa.eu/data-and-maps/…
I use data for 2019, and not relative reduction data because if:

- your emissions were very high
- you have reduced them more than others (in relative terms)
- but they're still higher than others in absolute terms

to me you're not a *leader*, you're just converging

Me yesterday: "we won't hear discourses of climate delay today as #IPCCReport2021 is released, but beware, from tomorrow on...."

Journalists: managing to fit 2 discourses of climate delay in a single short interview question
Specifically, the discourses here are no. 5 "All talk, little action" (AKA targetism), drawing attention (often presumed) achievements relative to other countries (rather than relative to the goal) and to future targets (rather than concrete achievements) Image
...and no. 3 "the free rider excuse", hinting that other countries are not willing to do their bit (so why should we try *even harder*)? Image

I am not sure what will happen first:

- the German coal exit (2038)

- or the day when German journalists will stop saying "we're *undisputed* climate *leaders*, but what can we do, we can't do everything *alone*!" (like here ⬇️)

🤦‍♂️🤦‍♂️
"We've committed to stop bragging about our presumed superiority on environmental matters by 2050"
Anyway I'm sure that day will become before the phaseout of combustion engine vehicle sales because... the German government is adamantly refusing to set a date for that

So apparently this is the UK government strategy for aviation & climate.

Let demand & supply expand & hope for a technological fix a couple of decades from now.

One could write a long thread about it, but really the story really is quite simple here...
What they propose is *literally the status quo*.

*Literally what we've been doing for the last few decades*.

The result? Aviation emissions have sky-rocketed. ⬇️
On the role that technology hopes / myths play in this context see this brilliant paper. It's all there.

#ClimateTwitter we need to talk about percentages and denominators.

Depending on what you divide it by, any measure bringing about carbon emission reductions can be made to look ridiculously small, or huge.

Good to be aware of these things [THREAD]
For illustrative purposes, let's take this measure I've been tweeting about lately: introducing a generalised 130km/h motorway speed limit in Germany (where there isn't any) would cut annual emissions by 1.9MTCO2e.

Is it much? Is it little?
So I get people in my mentions dividing that by the *total amount of global emissions in any sector, in any country*

The precise figures below may or may not be accurate but obviously if you do that, the impact will inevitably look very small

Opponents of #tempolimit in Germany argue that the resulting emission savings (2MTCO2e) are too small to matter.

In fact, they would help deliver *almost half* of the transport emission reductions (-5MTCO2e) promised in the government own emission budget for *this year*
