# The United States formally enters the Paris Agreement

Date: 2016

## The fact

On 3 September 2016, in Hangzhou, President Obama announced that the United States had formally joined the Paris Agreement, depositing acceptance with China the same day. A 2025 withdrawal is a later president’s child.

## Context

The 2015 Paris text sat as parent. Neighbouring CPP is a neighbour domestic rule. He did not sit as every other party’s NDC. Congress did not pass a climate statute for the deposit.

CPP 3 August 2015 is a neighbour EPA rule. TPP February 2016 is a neighbour signature that did not become law.

A United States president proposes, signs, vetoes, and directs the executive. Congress enacts statutes. The Federal Reserve, states, courts, and later presidents share later series. Office-holding is not authorship of every later outcome. Allegation is not a completed judgment. Legislative achievements require shared congressional attribution. He does not set the federal funds rate, write a state Medicaid waiver by himself, or convert a 2009 oath into a unique 2016 uninsured coefficient. A signature is not unique authorship of a House and Senate text. A troop order is not authorship of every later round. He is not president as of 27 August 2026. [Donald Trump](/people/mig-donald-trump) is president from 20 January 2025. [Joe Biden](/people/env-person-joe-biden) was president 2021–2025.

## Evidence and sources

White House (archives) carries the official instrument or communique. BBC records the same dated act independently.

## Significance

The path is decarbonization policy: a completed U.S. depositary entry into Paris, remaining later withdrawal named.

## What is established and what is not

Established: 3 September 2016 U.S. formal joining, independently reported.

Not established: a unique later U.S. emissions coefficient from Hangzhou, or that other parties’ NDCs uniquely sat because of that hour.

What would change the picture: a contradictory original with a different date or name, a later repeal, a court that vacated the instrument, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.

State notified. Other parties share the Agreement. Congress did not enact the NDC.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies The United States formally enters the Paris Agreement, not a later speech about The United States formally enters the Paris Agreement.

Co-authors and later implementers named in Context remain on the file. The United States formally enters the Paris Agreement on 2016-09-03 is not a licence to treat every later White House (archives) communique as this same act. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. This dossier refuses to average The United States formally enters the Paris Agreement into a personality. The contribution described on this Person row is limited to He directed the deposit. State notified. Other parties share the Agreement. Congress did not enact the NDC. That limit is the alternative to treating office-holding as authorship of every later series.
