Carbon dioxide, which makes up nearly 80 percent
of total global greenhouse gas emissions, can linger in the atmosphere for centuries, trapping heat long after it was released from a factory, automobile tailpipe or dried - up piece of tropical peat moss.
This Agreement shall enter into force on the thirtieth day after the date on which at least 55 Parties to the Convention accounting in total for at least an estimated 55 per cent of
the total global greenhouse gas emissions have deposited their instruments of ratification, acceptance, approval or accession.
At least 55 countries, which together are responsible for at least 55 per cent of
the total global greenhouse gas emissions — these were the requirements for a successful ratification of the Paris Agreement.
It is sometimes argued that since Australia is responsible for only around 1.4 % of
total global greenhouse gas emissions, we should not worry too much about reducing them.
Together, the countries that ratified the agreement are now responsible for more than 55 percent of
the total global greenhouse gas emissions.
The Paris Agreement entered into force on 4 November 2016, thirty days after the date on which at least 55 Parties to the Convention accounting in total for at least an estimated 55 % of

Accounting together for at least an estimated 55 % of

In accordance with Article 21, paragraph 1, of the Paris Agreement, the Agreement shall enter into force on the thirtieth day after the date on which at least 55 Parties to the Convention accounting in total for at least an estimated 55 % of
the total global greenhouse gas emissions have deposited their instruments of ratification, acceptance, approval or accession with the Depositary.
However, changes in land use can be important: estimates indicate that net global greenhouse gas emissions from agriculture, forestry, and other land use were over 8 billion metric tons of CO2 equivalent, [2] or about 24 % of
total global greenhouse gas emissions.
