Bill Gates at COP28 in Dubai on December 1, 2023 meeting Maldivian President
Mohamed Muizzu at the conference at COP28 in Dubai on December 2, 2023 and U.S. Vice President
Kamala Harris holding a bilateral meeting at COP28, December 2, 2023 COP28 was the largest-ever climate summit, with over 80,000 people accredited participants, up from 49,000 the previous year. Twenty-three thousand five hundred of the participants were from government teams, including more than 150 heads of state and government. A further 27,000 were policy experts, academics and representatives of fossil fuel producers, although this group was not given access to official negotiations. An additional 400,000 people were granted access to the surrounding "green zone", a conference space for activists and businesses. The number of attendees and the use of private jets by many of them was the subject of some criticism. The meeting was estimated to have the largest
carbon footprint of any climate summit to date.
Charles III,
King of the United Kingdom and the
Commonwealth realms, gave the opening speech at the summit. He expressed alarm at rising levels of pollution, saying that the world was "dreadfully far off track" its climate targets and warning that "we are carrying out a vast, frightening experiment of changing every ecological condition, all at once, at a pace that far outstrips nature's ability to cope". On the first day of the summit on 30 November 2023, a "
loss and damage" fund to compensate poor states for the effects of climate change was agreed upon. The fund aims to distribute funds to poor states harmed by climate change and is to be administered by the
World Bank. The host country, the United Arab Emirates, and Germany each pledged $100 million to the fund. Smaller pledges by the United Kingdom ($75 million), United States ($24.5 million) and Japan ($10 million) brought the total to $430 million on the first day. On 1 December 2023, activists protested outside the venue, calling for
ecocide—mass environmental destruction—to be made a crime at the
International Criminal Court. The same day, the Brazilian environment and finance ministers presented the
Tropical Forest Forever Facility, an international investment instrument to fund tropical forest conservation. On 3 December 2023, COP28 participants launched the
Declaration to Triple Nuclear Energy capacity from 2020 to 2050. The declaration was unveiled by U.S. climate envoy
John Kerry, and signed by 25 countries. The signing countries pledged to implement policies to extend their nuclear capacities, stating that nuclear power played a key role in cutting carbon emissions to net zero. On 2 December 2023, German Chancellor
Olaf Scholz called for a
phase-out of fossil fuels, including
coal,
oil and
natural gas, and reiterated Germany's commitment to be climate neutral by 2045, saying: "The technologies are there:
wind power,
photovoltaics,
electric motors,
green hydrogen." On 3 December 2023,
The Guardian revealed that COP28 President Sultan Al-Jaber had dismissed demands for a
fossil fuel phase-out two weeks previously, denying its basis in science and claiming it would prevent economic development. The following day, Al-Jaber held a press conference in which he walked back his comments, stating that he stated he "respects science" and thinks a phaseout of fossil fuel use is inevitable.
Draft and final agreements On 11 December, the day before the summit was scheduled to end, an initial draft of the final agreement was released. It was widely rejected by most Western countries because it avoided calling for a fossil fuel phaseout; The
Alliance of Small Island States described the draft as a "death certificate" for small island nations. Several African countries countered that wealthy countries had an obligation to take the lead on phasing out fossil fuels before expecting poorer countries to do so.
OPEC, a cartel of oil-producing countries, also urged participants to reject any mention of phasing out fossil fuels. the development of numerous "zero- and low-emission technologies", China and India did not sign the pledge to triple their output of renewable energy, and committed to coal power instead. Moreover, the choice to include carbon capture and storage in the list of "zero- and low-emission technologies" was questioned due to its relative expensiveness and lack of effectiveness in comparison to other methods. The participants of the conference pledged 85 billion dollars to different climate issues and made ten pledges: • Coalition for High-Ambition Multilevel Partnerships (CHAMP) for Climate Action Pledge was signed by 71 countries including the
United States,
Brazil,
France and
Germany. It includes commitments to promote international and subnational climate action, make new, more ambitious
nationally determined contributions by 2025, increase efforts for
climate change adaptation, and preserving biodiversity to limit warming to 1.5 degrees. • UAE Leaders' Declaration on a Global Climate Finance Framework was signed by 13 countries including the
United States,
India,
United Kingdom and
Germany. Includes targets of mobilizing $100 billion by 2025 and $5–7 trillion by 2030 to climate action, make a
debt reform, put in place an
emissions pricing mechanism, mobilize concession and private capital. • COP28 UAE Declaration on Climate and Health was endorsed by 143 countries including the
European Union,
China and
United States. Includes commitments to reduce negative health impacts from climate change in collaboration with
Indigenous peoples, women, local communities and health workers, and to prevent
zoonotic spillover. • COP28 Declaration on Climate, Relief, Recovery and Peace was adopted by 82 countries, including
Canada,
China,
Ukraine,
United States and
Rwanda. The declaration includes commitments to promote peace, environmental policies that support peace, prevent climate change from increasing conflict, help and empower people affected by
environmental degradation and conflict. • Global Renewables and Energy Efficiency Pledge was signed by 130 countries, including
Bhutan,
Brazil,
European Union,
Angola,
Bangladesh,
Burkina Faso and
Chad. The countries pledge to refer to energy efficiency as "first fuel" and double the rate of energy efficiency increase "from around 2% to over 4% every year until 2030". They also pledged to triple the capacity of renewable energy by 2030, ensuring a
just transition, increase renewable energy use and energy efficiency in an "environmentally responsible manner". • COP28 UAE Declaration on Sustainable Agriculture, Resilient Food Systems, and Climate Action was adopted by 159 countries including
Australia,
Belarus,
Brazil,
China and the
United States. It includes commitments to make the global food system more sustainable and climate resilient, promote
food security by helping
vulnerable people, pass to sustainable water management, include food systems into climate action strategies, protect and restore nature. • COP28 Gender-Responsive Just Transitions and Climate Action Partnership includes 76 countries, among others
Canada,
China,
Sweden,
Democratic Republic of the Congo,
Israel and the
United Arab Emirates. Its declaration includes a pledge to ensure a just transition, considering the effects on women especially indigenous, rural and with disabilities. • Global Cooling Pledge for COP28 was endorsed by 61 countries including
Denmark,
Japan,
Canada,
United States,
Spain. The declaration mentions the effects of increasing heat waves on health and economy (including food waste) and the contribution of the cooling industry to climate change. The signers pledged among others to cut GHG emissions from the cooling industry by 68% by 2050, increase the efficiency rate of air conditioning equipment by half by the year 2030, make a national plan for cooling, increase green spaces and blue spaces in cities and promote
passive cooling (that can "reduce a building's cooling load by more than 25%"). • COP28 Declaration of Intent was endorsed by 37 countries and includes different pledges to advance hydrogen engines (including derivatives of hydrogen) as a climate solution. • COP28 Joint Statement on Climate, Nature and People was endorsed by 18 countries including
China,
United States,
Canada,
France,
Germany and the
United Kingdom. The statement recognizes that the problems of
climate change,
biodiversity loss,
land degradation, ocean degradation and
social inequality are interconnected and cannot be solved separately. Therefore, the signers pledge to unify the plans to solve the problems into one integrated strategy.
Public health considerations Numerous sessions at COP28 were devoted to the impact of climate change on public health; it was the first COP to address the topic. "Lethal humidity," or 100%
humidity at temperatures of , was a particular focus of discussion.
Air pollution increases
respiratory conditions and increases the risk of
cancer and
heart disease. In a letter addressed to Sultan Al Jaber, "organisations representing more than 46 million health professionals" said a complete phase-out of fossil fuels was the only decisive way to deliver health for all. Previously, experts such as Edmond Fernandes had urged
UNFCCC to make
public health an essential part of all climate meetings and policies, calling human health integral to sustainable climate futures.
Food systems COP28 is the first COP where food systems were discussed. During the event, the UAE Declaration on Sustainable Agriculture, Resilient Food Systems, and Climate Action was adopted by 159 countries. == Controversies ==
