Net Zero Coalition | United Nations (2024)

What is net zero?

Put simply, net zero meanscutting 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°Cabove pre-industrial levels. Currently,the Earth is already about 1.1°C warmer than it was in the late 1800s, and emissions continue to rise.To keep global warming to no more than 1.5°C–as called for in theParis 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. Theenergy sectoris 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. More than 140 countries, including the biggest polluters – China, the United States, India and the European Union – have set a net-zero target, covering about 88% of global emissions. More than 9,000 companies, over 1000 cities, more than 1000 educational institutions, and over 600 financial institutions have joined the Race to Zero, 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, UN 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 itsrecommendationsat 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 sizableincrease of almost 9% in global greenhouse gas emissions by 2030, compared to 2010 levels. To keep global warming to no more than 1.5°C – as called for in the Paris Agreement – emissions need to be reduced by 45% 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.
