For a livable climate:
Net-zero commitments must be backed by credible action
What is net zero?
Put simply, net zero means cutting carbon emissions to a small amount of residual emissions that can be absorbed and durably stored by nature and other carbon dioxide removal measures, leaving zero in the atmosphere.
Why is net zero important?
The science shows clearly that in order to avert the worst impacts of climate change and preserve a livable planet, global temperature increase needs to be limited to 1.5°颁 above pre-industrial levels. Currently, the Earth is already about than it was in the late 1800s, and emissions continue to rise. To keep global warming to no more than 1.5°颁 – as called for in the Paris Agreement – emissions need to be reduced by 45% by 2030 and reach net zero by 2050.
How can net zero be achieved?
Transitioning to a net-zero world is one of the greatest challenges humankind has faced. It calls for nothing less than a complete transformation of how we produce, consume, and move about. The is the source of around three-quarters of greenhouse gas emissions today and holds the key to averting the worst effects of climate change. Replacing polluting coal, gas and oil-fired power with energy from renewable sources, such as wind or solar, would dramatically reduce carbon emissions.
Is there a global effort to reach net zero?
Yes, a growing coalition of countries, cities, businesses and other institutions are pledging to get to net-zero emissions. As of June 2024, , responsible for approximately 82 per cent of global greenhouse gas emissions, had adopted net-zero pledges either in law, in a policy document such as an national climate action plan or a long-term strategy, or in an announcement by a high-level government official. More than 9,000 companies, over 1000 cities, more than 1000 educational institutions, and over 600 financial institutions have joined the , pledging to take rigorous, immediate action to halve global emissions by 2030.
How do we ensure commitments are turned into action?
The growth in net-zero pledges has been accompanied by a proliferation of criteria with varying levels of robustness. To develop stronger and clearer standards for net-zero emissions pledges by non-State entities such as businesses, investors, cities and regions, and speed up their implementation, 缅北禁地Secretary-General António Guterres in March 2022 established a High-Level Expert Group on the Net-Zero Emissions Commitments of Non-State Entities. The Expert Group presented its recommendations at COP27 on 8 November 2022.
Are we on track to reach net zero by 2050?
No, commitments made by governments to date fall far short of what is required. Current national climate plans – for 195 Parties to the Paris Agreement taken together – would lead to a 2.6 per cent decrease in global greenhouse gas emissions by 2030, compared to 2019 levels. To keep global warming to no more than 1.5°颁 – as called for in the Paris Agreement – emissions need to be reduced by 43 per cent by 2030 and reach net zero by 2050. Getting to net zero requires all governments – first and foremost the biggest emitters – to significantly strengthen their Nationally Determined Contributions (NDCs) and take bold, immediate steps towards reducing emissions now.
Current national plans fall short of what is required
Most emissions come from just a few countries
The six?largest greenhouse gas emitters (China, the United States of America, India, the European Union, the Russian Federation, Brazil) accounted for 63 per cent of global emissions in 2023. By contrast, the 47 least developed countries accounted for only 3 per cent.
The G20, the group of the world’s largest 20 economies (Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Republic of Korea, Mexico, Russia, Saudi Arabia, South Africa, Turkey, the United Kingdom, the United States, and the European Union) are responsible for about 77 per cent of global greenhouse gas emissions.

Strengthening the standards for net-zero pledges
Governments have the biggest responsibility in the transition to net-zero emissions by mid-century. But businesses, investors, cities, states and regions also needs to live up to their net-zero promises. A high-level expert group convened by the 缅北禁地Secretary-General and chaired by former Canadian Minister Catherine McKenna developed stronger and clearer standards for net-zero emissions pledges by non-State entities.

Through this UN-backed campaign, companies, cities, financial and educational institutions and others are taking ambitious, immediate actions to halve global emissions by 2030.
The road to net zero
2015
196 countries adopted the historic Paris Agreement to reduce global warming and build resilience to climate change. Its overall goal: limit warming to no more than 1.5 degrees Celsius.
