Climate Reports

Key reports on climate action, climate economics, and on issues that highlight climate impacts and solutions.

UN | Report of the Secretary-General

September’s Climate Action Summit delivered important new actions, a surge in climate momentum, and a clear destination: 45% emissions cuts by 2030 on the way to a carbon neutral world by 2050. The Secretary-General’s report on the outcomes of the Summit highlights the way forward in 2020, and outlines ten priority areas of action.

UN Environment | Emissions Gap Report 2019

As the world strives to cut greenhouse gas emissions and limit climate change, it is crucial to track progress towards globally agreed climate goals. For a decade, UNEP’s Emissions Gap Report has compared where greenhouse gas emissions are heading against where they need to be, and highlighted the best ways to close the gap.

UNDP | Global Outlook Report 2019

The UN Development Programme (UNDP) and UN Climate Change (UNFCCC) have been working together since 2014 to support countries in developing their national climate plans --Nationally Determined Contributions for the Paris Agreement or NDCs. This report is the most detailed review yet of momentum since the Paris Agreement and is designed to both inspire and inform the UN Climate Action Summit in New York on 23 September.

UNCC | Climate Action and Support Trends

The report “Climate Action and Support Trends” was prepared as UN Climate Change input to the UN Climate Action Summit, and it puts a spotlight on the progress made over the past 25 years since the inception of the UN Framework Convention on Climate Change (UNFCCC). This can help in scaling up further action, as governments prepare to submit the next round of national climate action plans, known as Nationally Determined Contributions (NDCs), by 2020.

IPCC | Climate Change and Land (2019)

Land is already under growing human pressure and climate change is adding to these pressures. At the same time, keeping global warming to well below 2ºC can be achieved only by reducing greenhouse gas emissions from all sectors including land and food, the Intergovernmental Panel on Climate Change (IPCC) states in its latest report.

The report provides key scientific input into forthcoming climate and environment negotiations, such as the Conference of the Parties of the UN Convention to Combat Desertification (COP14) in New Delhi, India in September and the UN Framework Convention on Climate Change Conference (COP25) in Santiago, Chile, in December.

UNEP | Global Environment Outlook (2019)

UN Environment’s sixth Global Environment Outlook (2019) calls on decision makers to take immediate action to address pressing environmental issues to achieve the Sustainable Development Goals as well as other Internationally Agreed Environment Goals, such as the Paris Agreement.

By bringing together a community of hundreds of scientists, peer reviewers and collaborating institutions and partners, the GEO reports build on sound scientific knowledge to provide governments, local authorities, businesses and individual citizens with the information needed to guide societies to a truly sustainable world by 2050.

WMO | State of the Global Climate in 2018

The physical signs and socio-economic impacts of climate change are accelerating as record greenhouse gas concentrations drive global temperatures towards increasingly dangerous levels, according to a new report from the World Meteorological Organization.

The WMO Statement on the State of the Global Climate in 2018 , its 25th anniversary edition, highlights record sea level rise, as well as exceptionally high land and ocean temperatures over the past four years. This warming trend has lasted since the start of this century and is expected to continue.

IPCC | Climate Report 2018

Limiting global warming to 1.5ºC would require rapid, far-reaching and unprecedented changes in all aspects of society, the Intergovernmental Panel on Climate Change (IPCC) said in a new assessment. With clear benefits to people and natural ecosystems, limiting global warming to 1.5ºC compared to 2ºC could go hand in hand with ensuring a more sustainable and equitable society.

WMO | Greenhouse Gas Bulletin

The WMO Greenhouse Gas Bulletin reports on atmospheric concentrations of greenhouse gases in the earth’s atmosphere. The report found that levels of heat-trapping greenhouse gases in the atmosphere have reached another new record high, according to the World Meteorological Organization. There is no sign of a reversal in this trend, which is driving long-term climate change, sea level rise, ocean acidification and more extreme weather.

UN Environment | Emissions Gap Report

The flagship report from UN Environment is the definitive assessment of the 'emissions gap' – the gap between anticipated emission levels in 2030, compared to levels consistent with a 2°C / 1.5°C target. It found that global emissions are on the rise as national commitments to combat climate change come up short. But surging momentum from the private sector and untapped potential from innovation and green-financing offer pathways to bridge the emissions gap.

The New Climate Economy

The next 2-3 years are a critical window when many of the policy and investment decisions that shape the next 10-15 years will be taken. The New Climate Economy report found that leaders are already seizing the exciting economic and market opportunities of the new growth approach, while the laggards are not only missing out on these opportunities but are also putting us all at greater risk. More than US$26 trillion and a more sustainable planet are on offer, if everyone gets on board.
