Just to clarify, is your argument that with a Senate D majority, it's possible/likely that Senate Rs will oppose anything and everything? Can't argue with that. Still, asymmetry in hardball tactics has real costs, including to communities and our broader coalition.

it's super friendly and reminds me of the old days of course everything sucks and is terrible but at least we can be good to each other

I just want to add that this is a since question and that I’m grateful for the thoughtful replies already, keep it up, we have to be nice to each other and best the fascists plus do all the other big things faster too.

Got it. So it a better bill is implausible under threat of veto through 2028, then would it be fair to say that the question is whether to pass something soon (with more concessions) versus hope for a D president in 2029 (with potentially fewer concessions but definitely more contingencies)?

Not trying to put words in your mouth, just trying to tease out the political argument for “why now?”
110
Danny Cullenward @ghgpolicy.org · 01/10/2026
Just to clarify, are you suggesting that the prospect of electoral change isn’t big enough to make a better deal possible? As in, one needs a certain number of R votes and whether that’s a lot or a few the list of demands doesn’t change much?
100
Danny Cullenward @ghgpolicy.org · 01/10/2026
Yeah it’s not hard to be skeptical. That’s why I’m asking a sincere question about the political case for this timing.
320
Danny Cullenward @ghgpolicy.org · 01/10/2026
Thanks I’ll try to review those materials. So are you suggesting that, if the new bill doesn’t move fast, the political case for it more or less presumes that whatever happens in the election affects any next steps? Or that there might be more pressure to pass it after election results are known?

Can you say a bit more about why you think those odds are best now, and why a later bill won’t be better (or, if it is better, won’t be as likely to pass)? I’m not contesting the premise or the value of policy pragmatism. Just focused on the political argument here.

Danny Cullenward @ghgpolicy.org · 01/10/2026
I’m still not getting it. It seems to me Ds almost certainly have more leverage in 2027. Maybe it’s not much and maybe it’s irrelevant in terms of shifting policy under this president, but surely it’s better, in terms of basic power and potential policy, than today?
250
Danny Cullenward @ghgpolicy.org · 01/10/2026
I guess I’m not following. Are you saying that Ds think they have more leverage now, based on expectations for the new Congress, or that Rs are more willing to make concessions now on that same basis? As in, Rs won’t get what they want next year, so they deal now?
150
Danny Cullenward @ghgpolicy.org · 01/10/2026
Granted. And I think it’s safe to say the House is expected to change a lot more than the Senate. What’s the implication there, in your view?
120
Danny Cullenward @ghgpolicy.org · 01/10/2026
I take it you might be opposed to the deal; what I’m trying to understand is the reason this specific timing is supposed to be good for those of us who are interested in clean energy and climate. Have you heard anyone make that case?
240
Danny Cullenward @ghgpolicy.org · 01/10/2026
Can anyone explain to me why a national permitting deal is best negotiated now, mere weeks from an election that is likely to reshape federal power? Let’s stipulate that a deal of some kind is necessary and good; my question is what about the situation makes now more desirable than, say, Q1 2027?

But make no mistake, these debates matter because private standards can and will be used to lobby governments to take similar approaches. That is exactly why it is such a strategic mistake for NGOs like WRI to roll over to placate donors and standards-users.
160
Danny Cullenward @ghgpolicy.org · 29/09/2026
I don't think self-regulation can be managed without the credible threat of government policy. As @katearonoff.bsky.social writes, it's too easy for companies to walk away from purely voluntary regulation. newrepublic.com/article/2157...
Screenshot of text: "Generally only states can force that kind of change, and the credible threat of regulation is essential for voluntary initiatives like the GHG Protocol. At a time when it’s easier than ever for companies to abandon their climate commitments—and to stop funding green nonprofits—GHG Protocol secretariat staff may be understandably anxious to keep industry on side. Faced with the prospect of these hotly contested accounting methods being drafted into law, well-meaning environmentalists may have to decide between keeping corporate stakeholders engaged and happy, and maintaining scientific integrity."

Danny Cullenward @ghgpolicy.org · 29/09/2026
Transparency isn't sufficient, but it's a necessary first step. The other elephant in the room is self-regulation. Having companies participate is one thing; letting them dominate or manipulate decision-making processes is another.
130
Danny Cullenward @ghgpolicy.org · 29/09/2026
If WRI wants to demonstrate that it prioritizes scientific integrity above industry self-dealing, they should revisit the partnership with ISO and categorically reject any standards drafted by anonymous committees.
130
Danny Cullenward @ghgpolicy.org · 29/09/2026
There is a lot more to be said about the influence of the ISO partnership on the GHG Protocol. But I am not aware of any public documentation that explains the formal and informal mechanisms by which the ISO has decision-making authority in the GHGP process, so I can't add more.
230
Danny Cullenward @ghgpolicy.org · 29/09/2026
That said, the continued silence of senior WRI leadership, who are fully aware of what happened, is telling. I will repeat: they either don't care or they no longer have sufficient control over the process to do anything about it.
150
Danny Cullenward @ghgpolicy.org · 29/09/2026
I should add that while I found the behavior of certain WRI employees shocking, there are many great programs and people at WRI — including individuals who work on the GHG Protocol.

Danny Cullenward @ghgpolicy.org · 29/09/2026
As Jess says, the authority of standards-producers is a function of their acceptance by users. Having an almost monastic, oral culture and a partnership with ISO (which writes standards via anonymous committees) helps users maintain control. By design, opacity reduces accountability to outsiders.
151
Danny Cullenward @ghgpolicy.org · 29/09/2026
You might wonder how that kind of culture evolved in such a policy-relevant environment. Here again I think Jess' work helps explain how private authority develops and how its isolation from external technical feedback can lead to entrenchment.

Danny Cullenward @ghgpolicy.org · 29/09/2026
To some, unwritten theoretical principles were the most important issues to debate. Even if those principles produced the "wrong" answer, some said, they got there the "right" way. That's a silly claim, but it's easy to make if you don't have to write it down and put your name to it.
140
Danny Cullenward @ghgpolicy.org · 29/09/2026
To make matters worse, the debate over forest carbon accounting played out in an oral institutional culture that de-emphasizes written records. Until my colleague and I complained, there weren't even any board meeting minutes. (Board minutes were retroactively developed.)
140
Danny Cullenward @ghgpolicy.org · 29/09/2026
I think this has a lot of explanatory power, at least with respect to WRI. (WBCSD isn't hiding its industry-aligned advocacy.) But there's more to it. Some people genuinely believe that theoretical accounting principles require outcomes that make no physical, scientific, or policy sense.

Big ups to @katearonoff.bsky.social for covering this seemingly boring but actually really important story about the GHG Protocol. Standards are technical & opaque AND they’re where the politics happen. This is a classic case of “managing tons.” 🧵

The tech community does this with non-profit corporate structures, too. One can effect the same approach to voting powers for board seats with or without corporate shares, e.g. so a founder unilaterally controls a majority of a non-profit’s board seats + can hire or fire without cause.

Super great having your kids' voice recordings sent to a private company to farm data, thanks to the gross negligence of the leadership of the San Francisco Unified School District. Can't say enough good things about the teachers and schools. I sure wish the district wasn't incompetent.
