The lower house of the Czech Parliament voted on Tuesday evening to ratify the Paris climate agreement. The Czech Republic is the only European Union state not to have approved the document, which is aimed at curbing harmful emissions.
The Czech Senate voted to ratify the Paris accords earlier this year. The relevant legislation must now be signed by the president.
The Czech prime minister, Bohuslav Sobotka, said he was delighted that the country had signed up to the agreement and accepted responsibility with regard to future generations.
