There is a primacy to emission reductions, which is lost when you say "we need both". In my view, this is such an important nuance that is too often overlooked.

That's it, I just wanted to share that remark.
I am discovering the "Putting CO2 to use" report from 2019 (has there been an update?) and I am learning a lot: iea.blob.core.windows.net/assets/5065240

And similarly, CO2 and H2 are expected to be the key ingredients of new industries, from refrigeration, to mobility, to new building materials, ... as well as synthetic fuels, where both CO2 and H2 are used together!
Sometimes nature is just beautiful.

Yes: interestingly, the same applies to #hydrogen:
🥇 Chemicals, of which mostly NH3 for fertilizers,
🥈 Refining, of which mostly desulfurization of fossil fuels,
🥉 Other stuff, including metal (OK not food 🙃)

Quick #CCUS tweet: do you know what CO2 is mostly used for at the moment?
🥇 Urea, for fertilizers,
🥈 Enhanced oil recovery,
🥉 Other applications: food, metals...

For the life of me, I don't understand what they're talking about. Why is "the French" bad but "French people" good?
I'm fine being part of both, we know both are a shortcut for "a significant amount of French people" or "the French government" or whatever fits in context.
Quote Tweet
We deleted an earlier tweet because of an inappropriate reference to French people. We did not intend to offend.
Writing French people, French citizens, etc., is good. But "the" terms for any people can sound dehumanizing and imply a monolith rather than diverse individuals.

The climate crisis won't be solved by individuals. But it is worth noting that Jason Momoa, **the UN Environment Programme's Advocate for Life Below Water**, drives an EarthRoamer LTi, which delivers 9-14 mpg.

Dear , thanks for your email answer. I do not find your sources convincing.
I sent you a response with peer-reviewed sources, including a meta-analysis of LCA studies, more valuable than the single data point you chose to use.
Please let me know what you think.

Dear @dw_environment, what appears to be incorrect is the method used to quantify externalities.
@Umweltbundesamt has assumed that nuclear power cannot cost less than the worse technology in the portfolio, lignite. No justification is given, it's completely unscientific. twitter.com/dw_environment…

Changes are emerging across the climate system. Everywhere we look, the climate is changing rapidly.
Rate of recent changes is unprecedented in at least 2000 years for many climate metrics.
These changes are not natural; they are primarily caused by the burning of fossil fuels.

To be clear,
1. I'm not saying that new nuclear is cheap. But to assign lignite's externalities to it is at best misleading,
2. Nuclear may have issues, but greenhouse gas emissions are certainly not one of them.

But it's not the first time you are using biased information against nuclear power, and I have no idea why.
The day you can tell us exactly where these 117 g CO2 eq./kWh come from, we'll take the numbers seriously. But until then, it just harms your image of quality media.

#Nuclear LCA: we often joke about the 117 g CO2 eq./kWh value, but I have never seen a description of the calculation, or even a contribution analysis.

Une explication ? C'est quand même profondément inégal ?
En plus lorsque l'inflation est la conséquence de la hausse des prix des #carburants, l'état ne fait que subventionner nos modes de vie carbonés (!).
Complètement aberrant ce système.

Mmm, 80% of renewables and 20% of fossil gas means a #carbon intensity of roughly 150 g CO2 eq./kWh. Does it count as low-carbon to you?
With policies like this one, I think we will never see a sub-100 g/kWh European grid in our lifetimes 🤷

Hello I'm looking at your latest Climate Change Performance Index #CCPI results, I think there is an issue with the per-capita GHG score.
How do you find a value of 0.47 t CO2 eq./cap for 🇸🇪? 2.24 t for 🇨🇱?
ccpi.org/country/swe/

It's now 2023, and year after year, updating this #carbon budget slide has become a dreadful ritual.
I remember writing we had 1000 Gt left to emit, it feels like it was yesterday.

Alors ça reste élevé, quel que soit le pays, les GES inclus dans le calcul, ou la méthode – mais ce manque de rigueur de est inadmissible.
Encore une fois, c'est du manque de respect total envers les académiques et chercheurs qui développent ces modèles de calcul.

If the issue is on the non-renewable sources, maybe we can just rename it #lowcarbonH2 and everyone is happy?
As long as the #GHG threshold per kg of H2 produced is scientifically proven and respected (which will be very hard anyway for #blueH2) I think it's pretty sound.

50 industrial players, NGOs and think-tanks call on @EUCouncil to reject an amendment that would allow low-carbon hydrogen to meet #renewablehydrogen targets for #industry & #transport

Great tool to visualize your carbon footprint and how you can fit it (or not) into a more sustainable 2.3 t CO2 eq./year.
Would be great to have an English version, ?
