UNEP Emissions Gap Reports
"The Emissions Gap Report 2021 shows that new national climate pledges combined with other mitigation measures put the world on track for a global temperature rise of 2.7°C by the end of the century. That is well above the goals of the Paris climate agreement and would lead to catastrophic changes in the Earth’s climate. To keep global warming below 1.5°C this century, the aspirational goal of the Paris Agreement, the world needs to halve annual greenhouse gas emissions in the next eight years."
--UNEP Emissions Gap Report 2021 (web: Oct 26 2021)
"Latest UNEP Emissions Gap Report finds new and updated Nationally Determined Contributions only take 7.5% off predicted 2030 emissions, while 55% is needed to meet the 1.5°C Paris goal."

About UNEPThe UN Environmental Programme (UNEP) sets the environmental agenda for sustainable development within the United Nations system and serves as an authoritative advocate for the global environment. UNEP works with 193 members states, representatives of civil society and other major groups and stakeholders. UNEP headquarters are in Nairobi, Kenya. |
Net Zero Tracker
The Net Zero Tracker (NZT) collects data on net zero targets and pledges by nations, states and regions, cities and companies. It reports on factors which indicate the integrity and seriousness of entities to cut net emissions to zero. The Net Zero Tracker is operated by the Energy & Climate Unit (UK) and partners.

IPCC Carbon Budget
Countries that signed the UN Framework Convention on Climate Change adopted a target to stop the average global temperature from rising before it reaches 2°C above pre-industrial levels.
The Fifth Assessment Report of the International Panel on Climate Change (IPCC) quantifies the global maximum CO2 the world can still emit and also have a likely chance of keeping global average temperature rise below 2°C above pre-industrial temperatures. It reports that the goal is likely to be met if cumulative emissions (including the 535 GtC emitted by the end of 2013) do not exceed 1 trillion tonnes of carbon (PgC). A gigatonne of carbon (1 GtC) is the same as a petagram of carbon (1 PgC).
If you accept the 2°C target, the world needs to emit no more than 465 GtC by the time carbon emissions end. Many developing countries also support a reduction in the target to keep global average temperature increases below 1.5°C above pre-industrial levels.
