Another day, another instance of gaslighting in the German #Tempolimit debate.
Here is the leader of the pro-business FDP party claiming that motorway speed limits "do not necessarily reduce emissions", because... EVs 🤦♂️ zeit.de/2021/28/christ…
So let's go through this once again.
1. The German government's *own estimates* find a significant emission reduction from motorway speed limits
...which is why the International Energy Agency recommends the introduction of 100km/h motorway speed limits from now to 2030 - the decade where we expect EVs sales to boom
So basically the *only scenario* in which a speed limit does *not* result in reduced emissions is when 100% of the fleet is fully electric, and 100% of the grid is zero-carbon. We're a *long* way from that. [ENDS]
PS: BTW - and *you couldn*t make this up* - Lindner himself says later on in the interview that "there will be internal combustion engines on Europe streets *for the next few decades* (when it comes to arguing against EV subsidies, and in favour of e-fuels).

#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.
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*
The interview is topped-off with dramatic, populist undertones: "the voters can decide: either freedom of mobility with us, or bans & constraints with the Greens"
...as well as inaccuracies: Scheuer claims that German motorways are "the safest roads in the world" (no less). That's not correct.
Likely next German Chancellor Laschet claims that introducing a generalised motorway speed limit (still not a thing in Germany!) would be "symbolic policy" as there is no proof that it would reduce emissions.
The estimated CO2 reduction impact of a motorway speed limit is actually comparable to that of a substantial CO2 tax or a ban on domestic flights (see link in the thread)
@lamb_wf Transport accounts for 14-15% of global GHG emissions according to the latest figures (2018). Most of it from road transport (11% of global emissions). Aviation is 1.6%.
Road transport is both one of the highest emitting subsectors AND one of the subsectors with the most rapid growth since 2010 (+2% per year)
