A deux reprises, j’ai pris part à des actions de désobéissance civile climat-biodiversité en tant que scientifique. La première fois en octobre 2020 sur le tarmac de Rossy CDG à l'invitation de @NonAuTerminal4 @Alternatiba_ @ANVCOP21 @Greenpeacefr @amisdelaterre @Advocnar 1/ 
J’étais accompagné de J. Guillet, astrophysicien porte-parole du collectif “scientifiques en rébellion” @SciRebFr. Jérôme, ainsi que 6 activistes, sera poursuivi en justice pour “troubles au fonctionnement d’installations destinées au contrôle de la circulation des aéronefs”. 2/
Procès le 7 octobre 2021. 7 témoignages poignants. L’Etat tente sans surprise (ni succès) de travestir les faits matériels. Que de temps perdu … mais on aura parlé des conséquences concrètes du transport aérien pour le climat et la vie de centaines de milliers de riverains. 3/
This Friday, EU energy ministers aim to decide on measures to soften the impact of the escalating #gas and #electricity bills on households and businesses. The decisions should be guided by the following principles. A 🧵 1/10
Direct, timely & targeted payments to households & companies that need support are better than general public spending to lower energy prices for all consumers. The latter is very costly & can undermine the crucial need to save as much energy as possible before winter. 2/10
Current pricing mechanisms in #electricity market work and must be maintained. Marginal pricing is central to the integration of renewables and necessary to incentivise uptake of #heatpumps and #electricvehicles. Read more in our new paper (in German) bit.ly/3fs6Rmj 3/10

Amid all the hustle and bustle, it's hard to keep track of what actually happened yesterday in Brussels. Here are some takeaways from the diplomatic showdown (NATO, G7, EUCO) including @POTUS attendance & @ZelenskyyUa speeches. A 🧵 /1
First, HR news: @CharlesMichel was re-elected EUCO President for another 2,5 years; @jensstoltenberg's mandate was extended by a year as NATO Secretary-General. /2 politico.eu/article/charle…
Second, NATO news: NATO agreed on 4 new battlegroups on its "Eastern flank". In total, 40,000 soldiers stationed next to the border. More resources will be spent to prevent cyberattacks & to prepare for potential biological & chemical attacks./3 nato.int/cps/en/natohq/…
Präsident Selenskyj, die #Ukraine kann sich auf unsere Hilfe verlassen! Wir haben Sanktionen verhängt, die wirken. Viele der härtesten Folgen werden sich erst in den kommenden Wochen zeigen. Und: Wir schärfen die Sanktionen ständig nach. #Bundestag
Tag für Tag schreiben mir Bürgerinnen und Bürger besorgt: Wird es Krieg geben, hier bei uns? Auf diese Frage kann es nur eine Antwort geben: In 80 Jahren haben wir das Unvorstellbare vermieden, dabei muss es bleiben! Die #NATO wird nicht Kriegspartei in der #Ukraine.
Auf Energieabhängigkeit und hohe Energiepreise lässt sich nur mit Erneuerbaren Energien und Energieeffizienz reagieren. Unser Ziel - #Klimaneutralität in Deutschland bis 2045 - ist wichtiger denn je. Nicht: „Jetzt mal langsam“, sondern „Jetzt erst recht“ – so lautet die Devise!

Welcome to DAY 1⃣ of #PPCParis! Florence Haegel from @SciencesPo_CEE is opening the conference now: "The overlapping of #EU2022FR with the #FrenchElections of 2022 will frame the agenda of the French Presidency to a great extent"

As part of these welcoming words to #PPCParis we thank Florence Haegel for her warm words and short analysis of the upcoming French Presidency of the @EUCouncil
We're about to hear also from TEPSA Secretary-General @CloosJim

We have published an English summary of our hydrogen report: umweltrat.de/SharedDocs/Dow…
Key messages:
Hydrogen is necessary for #climateneutrality, but needs to be used in an efficient manner. Only #greenhydrogen produced from #renewable power can be produced sustainably.

Hydrogen is necessary for #climateneutrality, but needs to be used in an efficient manner. Only #greenhydrogen produced from #renewable power can be produced sustainably.
Blue hydrogen is currently discussed as a bridging technology. In our opinion, it is not sustainable due to residual GHG emissions, insufficient short-term #CCS capacity and the risk of #fossil infrastructure lock-in. Therefore, it should not receive public subsidies.
Stringent certification is necessary to minimize the environmental footprint and social issues of hydrogen. This is both true for imports and European production.
An additionality criterion for renewables can ensure that green hydrogen does indeed reduce carbon emissions.

Hydrogen is one lever for #climateneutrality in areas which are challenging to electrify. But where does #H2 research stand currently & what new findings are available? With our new impulse "12 Insights on #Hydrogen" we shed light on the subject. 🧵 👇 1/8
Finding 1: By 2050, carbon-free #H2 provides 1/5 of world's final energy, mainly made from renewable electricity. H2 should first decarbonize industry, shipping, aviation + consolidate a #greenenergy system. H2 infrastructure should meet need of industry, ports & power grids. 2/8
Finding 2: Financing #greenH2 in no-regret applications (industry, power, shipping, aviation) needs additional policy support since #carbonprice will remain insufficient over the next decade. No credible financing strategy for introducing green #H2 in #households. 3/8
With the #SofiaDeclaration, the 6 #WesternBalkans countries have committed to #climateneutrality in 2050. To achieve this, a #lignite phase-out for power production is needed, ideally by 2040. To support the debate, we have developed 6 pathways (THREAD). #EUGreenDeal 1/12
Where do we stand today? WB-6 power markets consist almost exclusively of two generation technologies: #lignite and #hydro. The share of either source varies considerably between the countries. 2/12
Finding 1: 90 % of #lignite power plants in the #westernbalkans was put into operation 30 or more years ago. 40 % of the capacities are older than 40 years. The power plant park is in urgent need of #modernisation. 3/12

~0.35%. That’s the annual methane reduction needed for agriculture CH4 to be #ClimateNeutral. Reduce ~5% annually, we can neutralize all additional warming from ag CH4 since the '80s. WE CAN DO THIS!

GWP* vs GWP100 better describes how #methane emissions impact the climate. Using GWP100 overestimates the warming impact of constant CH4 emissions by 3-4 times.
AND GWP100 misses climate benefits with decreasing emissions.
AND undersells warming when CH4 emissions rise.

Why is GWP* important? From the paper: GWP* emphasizes CH4 reductions can only contribute meaningfully to limiting climate change, as long as CO2 hits net-zero.
GWP* shows the true benefits w/ CH4 cuts. Making the work farmers/ranchers are doing to cut CH4 more significant. 3/

Ahead of crucial #COP26 & amid intensifying climate crisis, the @EU_ Commission today presents the #FitFor55 package aiming at cutting EU emissions by 55% by 2030. Implementation will require far-reaching changes in mobility, housing, land use, industrial production. 1/11
The @EU_Commission sends the following signal to the international community: EU ups the ante to align the block on the 1.5° pathway, as pledged in the #ParisAgreement. #Fitfor55 will show whether the EU is ready to walk the climate talk while ensuring a just transition. 2/11
The walk will only be fully successful if environmental integrity and social and distributional justice go hand in hand. Agora welcomes the setting up of a social fund to ensure that its #Fitfor55 proposals lead to greater social solidarity. 3/11
