How can President Trump unilaterally withdraw the USA from the Paris Accord?

As Little Nemo perfectly said, if an international agreement is lawfully concluded, then the terms of withdrawal are often spelled out in the agreement. International agreements manage relations between countries, not Presidents, and Presidents are generally bound to act within the constraints that the United States places on them, even in dealing with foreign powers.

I don’t know hardly anything about the Paris Agreement but if it was legally concluded by President Obama, then the United States has formed an obligation to comply with the agreement. I offer no opinion at all as to whether this agreement constitutes a treaty requiring Senate advice and consent, or if it is an executive agreement.

It doesn’t really matter, since there is nothing in the treaty to comply with. It’s Kellogg-Briand level symbolism.

As for what treaties Presidents can withdraw from, if it’s not ratified or otherwise approved by the Senate, a President can get out the same way he got in. Just do it. However, if it is ratified or otherwise approved, the conditions for leaving it will be set out in the treaty. I don’t believe a President can just unilaterally revoke a ratified treaty.

The same principle applies to any international agreement.

Except nothing about the agreement is non-binding, so the only “violation” would be not being a party to it.

Isn’t international diplomacy just wonderfully illogical?

Thanks for all the replies. But now my head hurts.

It’s simple. Obama said, “We are doing this thing because I said so.”
Trump said, “We’re not doing the thing anymore because I said so.”

Well, this is GQ so I’m not going get all GD on the subject, but if even half the countries who signed up for this meet the goals, I’ll eat my hat.

Also, it’s not a treaty. It’s a “voluntary agreement”.

Aren’t all treaties voluntary, or at least ostensibly voluntary, agreements?

Yes. Treaties are voluntary agreements, but there are other voluntary agreements that aren’t treaties, and this is one.

I’ll agree this is a pretty soft agreement. From what I can see, the only thing a country is committing to by signing on is to produce a public record of how much greenhouse gases it produces; to lower that amount by 2050 (although how much it will be lowered isn’t specified); to assist developing countries in lowering their production of greenhouse gases (although assistance is voluntary); and to show up for the annual meetings in Paris. So there’s not a lot a signatory can do to violate the agreement. President Obama essentially promised we’d lower our greenhouse gas production in thirty-three years and now President Trump has taken that burden off us.

While the text of the Agreement is very soft - the only way to get the heads of govt. to agree in the first place - the practical effects have been a bit stronger.

So less Jobs in the growing sector of renewable energy; probably some empty gestures for dying coal (which is cheaper from China, which is currently switching to renewables). Also less Money to help developing countries with renewable energy, which means less Goodwill and more influence of China (which has been building infrastructure and Long-term development in Africa for Goodwill and resources).

Not quite: The Agreement itself is binding, once it has been signed. There is however no Penalty clause spelled out, so not obeying it would not cause any tangible harm (besides loss of credibility, but that’s not really a Problem anymore for the US with Trump).

However, leaving the Agreement means (similar to Brexit for the UK): no longer sitting at the table during negiotiations.

Staying and extending the Goals, or neglecting or whatever else excuse would have meant a Chance to Keep negotiating for trade deals: not only cap-and-trade, but building solar or wind in developing countries. These deals will now go to China and other countries instead of the US.

Recognizing that “binding” and “not binding” can sometimes depend on how you interpret the legalese, most liberal sites I’ve seen comment on this say that it’s definitely non-binding and thus there was no reason to withdraw. Is that just a political argument?

The US govt. has a Long, Long record of breaking (or ignoring) treaties. That’s hardly a precedent.

And Trump has a Long Long record of being utterly unpredictable, which means, unreliable, which is not what countries wanting to make deals are looking for. Quite the opposite, countries want to make deals that have a Chance of continuing even if Administrations Change.
Currently, very few countries who have other Options feel inclined to make deals with the US, because there is no guarantee that deals will be kept.
Companies are also wary to invest in the US because of the political climate in General. Putting tribal Affiliation (like denying climate Change) higher than reality makes Business dealings difficult.

I am not a lawyer myself, so I haven’t looked at the Details of the Agreement, but instead rely on the experts being cited.

Generally speaking, the US refuses to be bound by international law. I suspect that most US Americans would be shocked that their government refuses to ratify many of these conventions, e.g., protecting women, children, and people with disabilities.

There was no Treaty.

Treaties that end wars are so much voluntary, at least by the losing party.

Find me some Ratified by the US Senate Treaties we broke with international parties.

Most Native American “Treaties” are signed agreements.

Cite?

Yes, the US refuses to ratify some treaties that* in effect* would bind the USA but not other signatories. China, for example, ignores treaties.
