The United Arab Emirates, he said, was “rightly proud” of its role in bringing “transformational change” to the planet.
“The world needed to find a new way. And by following our North Star, we have found that new path,” he said to applause, referring to the goal of limiting warming to 1.5 degrees Celsius.
Jaber hours earlier released a draft of the agreement aiming to bring on board countries from islands fearing extinction to Saudi Arabia, which has led the charge to keep exporting its oil.
Toughening language from an earlier draft that was roundly denounced, the agreement calls for “transitioning away from fossil fuels in energy systems, in a just, orderly and equitable manner, accelerating action in this critical decade, so as to achieve net zero by 2050 in keeping with the science”.
It marked the first mention of all fossil fuels in 28 years of climate summits.
China said that developed countries must “take the lead” in the energy transition and deliver financial support to developing nations “without delay”.
“Developed countries have an unshakeable, historical responsibility for climate change and therefore must take the lead to embark on the 1.5 degree Celsius pathway ahead of the rest of the world,” Chinese vice environment minister Zhao Yingmin said.
“For the first time in 30 years, we might now reach the beginning of the end of fossil fuels,” EU climate chief Wopke Hoekstra said before heading into the plenary session.
Danish negotiator Dan Jorgensen, part of a group in charge of making headway, called the agreement “historic progress”.

US Special Presidential Envoy for Climate John Kerry said the agreement was a positive step.
“Everyone here should feel good … I am in awe of the spirit of cooperation that has brought everybody together,” Kerry said.
The agreement could speed up the transition to a cleaner and healthier economy and keep the world on track to meet the climate goals of the Paris Agreement, EU Commission President Ursula von der Leyen said on Wednesday.
“It is good news for the whole world that we now have a multilateral agreement to accelerate emission reductions towards net zero by 2050, with urgent action in this critical decade,” von der Leyen said in a statement.
“The world has committed to tripling renewable energy capacity and doubling the rate of energy efficiency improvements by 2030. This gives powerful momentum to the transition away from fossil fuels.”
The text, however, stopped short of calls during the summit for a “phase-out” of oil, gas and coal, which together account for around three-quarters of the emissions responsible for the planetary crisis.
The planet has already warmed by 1.2 degrees and scientists say 2023 was likely the warmest in 100,000 years, as storms, droughts and lethal wildfires expand around the world.
Low-lying islands fear extinction from rising sea levels and worsening storms, with the Marshall Islands denouncing the earlier draft as a “death warrant”.
The bloc of small island states called the revised text “an improvement” but it reiterated concerns, saying that the deal was “incremental and not transformational”.
Jaber’s earlier draft merely suggested that nations “could” reduce the consumption and production of fossil fuels, among other options, drawing fury from green groups.
Environmentalists virtually all saw the new text as an improvement, although many cautioned that there will still far more to do.

“We are finally naming the elephant in the room. The genie is never going back into the bottle and future Copss will only turn the screws even more on dirty energy,” said Mohamed Adow, director of the Power Shift Africa think tank, referring to the annual UN climate meetings known as Conferences of the Parties.
“Some people may have had their expectations for this meeting raised too high, but this result would have been unheard off two years ago, especially at a COP meeting in a petrostate,” he said.
The agreement also made more explicit the near-term goals in the goal of ending net emissions by 2050.

It called for the world to cut greenhouse gas emissions by 43 per cent by 2030 compared with 2019 levels.
Rachel Cleetus, policy director at the Union of Concerned Scientists, said the deal “sends a strong signal that world leaders recognise that a sharp turn away from fossil fuels toward clean energy in this critical decade and beyond, aligned with the science, is essential to meet our climate goals”.
But Jean Su of the Centre for Biological Diversity, while seeing progress, said there were still “cavernous loopholes” for fossil fuels.
The agreement tackles only fossil use in energy, not in industrial areas such as production of plastics and fertiliser.
She also voiced alarm at the recognition of the role of “transitional fuels”, which she saw as a code word for producers of natural gas and other fossil fuels such as the United States on the grounds of energy security.
While not using the term “phase-out” on fossil fuels, it endorses work towards a phase-down of “unabated coal power” – meaning that coal with carbon capture technology to reduce emissions, panned by many environmentalists as unproven, could continue.
The biggest-ever Cop meeting hosted more than 88,000 people, including a record number of lobbyists from the fossil fuel industry.
The 2015 Paris summit endorsed checking warming at 1.5 degrees – a goal repeated in the latest draft, but which critics say is virtually impossible without serious efforts to curb oil, gas and coal.
