Report of the Secretary-General on the 2019 Climate Action Summit and the Way Forward in 2020
3
Science is telling us that the impacts of climate change
are happening now, and faster than we had predicted. This is
becoming increasingly evident in our daily lives. In its report
titled “United in Science” (2019) published on the day of the
Climate Action Summit, the Summit’s Science Advisory Group
undertaken by major partner organizations in the domain of
global climate change research: all pointed to 2019 as one of
the warmest years on record and extreme weather events have
hit populations from the Bahamas to Mozambique through to
Australia, Western Europe, and the United States.
Science also tells us what needs to be done and how. The
“Report of the Intergovernmental Panel on Climate Change
(IPCC) on the Impacts of Global Warming of 1.5 above pre-
Industrial Levels” (2018), demonstrates that we must limit
global warming to 1.5 by the end of this century to avoid
irreversible and catastrophic impacts. This means that carbon
dioxide (CO) emissions need to decline by about 45 percent
by 2030 and reach net zero in 2050. While the IPCC says that
this goal is within reach, to achieve it would require urgent and
unprecedented social and economic transformation.
Against this backdrop, the initial national climate pledges
(Nationally Determined Contributions, or NDCs) made under
countries’ current climate plans imply global warming of about
3 by 2100, with warming continuing afterwards. In addition,
2015-2019 has seen a continued increase in CO levels and
other key greenhouse gases (GHG) in the atmosphere to new
records, with CO growth rates nearly 20 percent higher than
reversing by 2030, let alone 2020.
People around the world have demonstrated that they
understand the severity of the challenge and are asking for
solutions. Youth in particular have taken to the streets in
the millions, demanding urgent action to be taken. This call
cannot be left unanswered.
Responding to the urgent need to scale-up climate action,
the Secretary-General convened the Climate Action Summit on
23 September 2019 to focus global attention in the face of the
worsening climate crisis and to forge new pathways ahead to
support the achievement of the Paris Agreement and the 2030
Agenda for Sustainable Development. Leaders at all levels were
requested to step-up to the challenge and demonstrate that
business as usual is no longer acceptable.
Grounded in science and building on the global framework
of the Paris Agreement, the Summit focused on nine key
action areas: youth and public mobilization; social and
resilience and adaptation; nature-based solutions; industry
transition; mitigation strategy; and cities infrastructure and
local action.
The Secretary-General built coalitions consisting of
governments, business leaders, subnational actors, indigenous
peoples and other civil society stakeholders to develop
transformative initiatives for which participants would be
held accountable to implement. This novel collaboration
between a wide range of stakeholders was critical to ensure
solutions had the potential to address the deep social and
economic transition required to limit global temperature
increase to no more than 1.5 and to transition to climate
resilient economies.
Countries were also asked to present concrete and realistic
plans compatible with these goals. The Secretary-General
asked leaders to come to the Summit to present plans, not
make speeches. The most ambitious plans were presented
on 23 September, creating a unique opportunity to showcase
leadership towards transformative climate action that would
make change in the world.
In addition to the Climate Action Summit, the Secretary-
21 September, bringing young people into the United Nations,
alongside other global leaders, to share their concerns, ideas
and commitments for greater climate action. The Youth
Summit was a unique opportunity to ensure youth voices from
all over the world were heard and their ideas considered in
global decision-making processes.
To provide strategic guidance and oversight of the
Summit, the Secretary-General established a Steering
Committee (comprised of heads of United Nations agencies
and international organizations, and business, as well as
academia and civil society representatives); a Science
Advisory Group, and an Ambition Advisory Group, composed
These groups met to discuss key issues in the preparation of
the Summit and provided advice to the Secretary-General and
coalitions to support development of ambitious initiatives for
climate action.
We are in a climate crisis.
