Tackling Climate Change
Goal 13 calls for urgent action to combat climate change and its impacts. It is intrinsically linked to all 16 of the other Goals of the 2030 Agenda for Sustainable Development. To address climate change, countries adopted the Paris Agreement to limit global temperature rise to well below 2 degrees Celsius.

Why we need action
Climate change is now affecting every country on every continent. It is disrupting national economies and affecting lives, costing people, communities and countries dearly today and even more tomorrow.
People are experiencing the significant impacts of climate change, which include changing weather patterns, rising sea level, and more extreme weather events. The greenhouse gas emissions from human activities are driving climate change and continue to rise. They are now at their highest levels in history. Without action, the world’s average surface temperature is projected to rise over the 21st century and is likely to surpass 3 degrees Celsius this century—with some areas of the world expected to warm even more. The poorest and most vulnerable people are being affected the most.
A race we can win
Affordable, scalable solutions are now available to enable countries to leapfrog to cleaner, more resilient economies. The pace of change is quickening as more people are turning to renewable energy and a range of other measures that will reduce emissions and increase adaptation efforts.
But climate change is a global challenge that does not respect national borders. Emissions anywhere affect people everywhere. It is an issue that requires solutions that need to be coordinated at the international level and it requires international cooperation to help developing countries move toward a low-carbon economy.
To address climate change, countries adopted the Paris Agreement at the COP21 in Paris on 12 December 2015. The Agreement entered into force less than a year later. In the agreement, all countries agreed to work to limit global temperature rise to well below 2 degrees Celsius, and given the grave risks, to strive for 1.5 degrees Celsius.
Implementation of the Paris Agreement is essential for the achievement of the Sustainable Development Goals, and provides a roadmap for climate actions that will reduce emissions and build climate resilience.
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.
The Special Report on Global Warming of 1.5ºC was launched on Sunday, 7 October, in Incheon, Republic of Korea. It will be a key scientific input into the Katowice Climate Change Conference in Poland in December, when governments review the Paris Agreement to tackle climate change.

The Paris Agreement on climate change
The UN continues to encourage all stakeholders to take action toward reducing the impacts of climate change.
COP25: Madrid, 2019
The 2019 UN Climate Conference took place in Madrid, Spain from 2-13 December.
The conference was designed to take the next crucial steps in the UN climate change process. The conference served to build ambition ahead of 2020, the year in which countries have committed to submit new and updated national climate action plans. Crucial climate action work was taken forward in areas including finance, the transparency of climate action, forests and agriculture, technology, capacity building, loss and damage, indigenous peoples, cities, oceans and gender.
COP24: Katowice, 2018

The 2018 UN Climate Conference took place in Katowice, Poland from 2-14 December.
The conference finalized the rules for implementation of the Paris Agreement on climate change under the Paris Agreement work programme (PAWP). It also included a number of high-level events, mandated events, action events and roundtables.
COP22: Marrakesh, 2016
High-Level Event Towards Entry into Force: 21 September, 2016
United Nations Secretary-General Ban Ki-moon convened a special “High-Level Event on Entry into Force of the Paris Agreement on Climate Change” on 21 September at the UN Headquarters in New York, to provide an opportunity to other countries to publicly commit to joining the Paris Agreement before the end of 2016.
Paris Agreement Signing Ceremony, 22 April 2016
To keep the global spotlight focused on climate change and build on the strong political momentum from Paris, United Nations Secretary-General Ban Ki-moon invited representatives of all countries to sign the Paris Agreement on climate change at a special Ceremony at the United Nations Headquarters on 22 April.
Cop21, 12 December 2015
The Paris Agreement was adopted by all 196 Parties to the United Nations Framework Convention on Climate Change at COP21 in Paris on 12 December 2015. In the agreement, all countries agreed to work to limit global temperature rise to well below 2 degrees Celsius, and given the grave risks, to strive for 1.5 degrees Celsius. Implementation of the Paris Agreement is essential for the achievement of the Sustainable Development Goals, and provides a roadmap for climate actions that will reduce emissions and build climate resilience.
The Paris Agreement on climate change officially entered into force on 4 November 2016, after 55 countries accounting for 55 per cent of the total global greenhouse gas emissions, deposited their instruments of ratification, acceptance or approval with the UN Secretary-General.
As of June 2020, 195 signatories and 189 countries have joined the Paris Agreement.
The Paris Agreement is an ambitious, dynamic and universal agreement. It covers all countries and all emissions, and is designed to last. This is a monumental agreement. It solidifies international cooperation for climate change. It provides a way forward.
The Paris Agreement sends a powerful signal to markets that now is the time to invest in the low emission economy. It contains a transparency framework to build mutual trust and confidence.
It will serve as an important tool in mobilizing finance technological support and capacity building for developing countries. And it will also help to scale up global efforts to address and minimize loss and damage from climate change.
Paris is a beginning—we now have to implement the Agreement. But we have taken a giant step forward.
The proof will be in the implementation, by governments, businesses and civil society.
The agreement not only formalizes the process of developing national plans, but also it provides a binding requirement to assess and review progress on these plans. This mechanism will require countries to continuously upgrade their commitments and ensure that there will be no backtracking.
This agreement is a clarion call from governments that they are ready for implementing the 2030 Sustainable Development Agenda.
It is doable. Taking climate action now makes good economic sense. The more we delay, the more we pay. We can promote economic growth, eradicate extreme poverty, and improve people’s health and well-being by acting today.
