The 2019 United Nations Climate Change Conference, known as COP25, was a UN climate summit held in Madrid, Spain, in December 2019 under Chile's presidency, chaired by Carolina Schmidt.
2021 United Nations Climate Change Conference
The 2021 United Nations Climate Change Conference, known as COP26, was a UN climate summit held in Glasgow, Scotland, in 2021, producing the Glasgow Climate Pact.
2022 United Nations Climate Change Conference
The 2022 United Nations Climate Change Conference, known as COP27, met in Sharm el-Sheikh, Egypt, in November 2022 and agreed to create a fund for loss and damage.
2023 United Nations Climate Change Conference
The 2023 United Nations Climate Change Conference, known as COP28, was held in Dubai, United Arab Emirates, concluding the first global stocktake under the Paris Agreement.
2026 in climate change
2026 in climate change centered on implementing prior commitments: the COP31 summit met in Antalya, Türkiye in November 2026, and temperatures were forecast near 1.44 °C above pre-industrial levels.
45Q tax credit
The 45Q tax credit is a United States federal tax credit, created in 2008, that pays per metric ton of carbon dioxide captured and stored, supporting carbon capture projects.
Adaptation Fund
The Adaptation Fund is a multilateral climate fund established under the Kyoto Protocol in 2001 to finance adaptation projects in developing countries vulnerable to climate change.
Alliance of Small Island States
The Alliance of Small Island States (AOSIS) is a coalition of small island and low-lying coastal developing states, formed in 1990 to amplify climate voices.
Artificial upwelling
Artificial upwelling is a proposed marine geoengineering technique that pumps nutrient-rich deep water to the sunlit surface to boost phytoplankton growth and, in principle, sequester CO2.
Baku to Belém Roadmap
The Baku to Belém Roadmap is a climate finance initiative launched at COP29 in 2024 to scale up funding to USD 1.3 trillion a year by 2035.
Bali Road Map
The Bali Road Map is a set of UN climate decisions adopted at COP13 in Bali in December 2007, launching two-year negotiations toward a post-2012 climate agreement.
Bioenergy with carbon capture and storage
Bioenergy with carbon capture and storage (BECCS) is a carbon dioxide removal technology in which biomass produces energy and the resulting CO₂ is captured and stored geologically.
C40 Cities Climate Leadership Group
The C40 Cities Climate Leadership Group, known as C40 Cities, is a network of city governments founded in 2005 that now spans 97 cities representing 700 million people.
Carbon dioxide removal
Carbon dioxide removal (CDR), also called carbon removal, is the removal of CO2 from the atmosphere and durable storage, by planting trees or direct air capture.
Carbon Disclosure Project
CDP, formerly the Carbon Disclosure Project, is a not-for-profit founded in London in 2000 that collects self-reported climate, water, and forests data from over 25,800 organizations.
Carbon emission trading
Carbon emission trading, also called cap and trade, is a market-based climate policy in which governments set an emissions cap and companies buy or sell tradable allowances.
Carbon leakage
Carbon leakage is the shift of CO₂ emissions abroad when strict climate policies push companies to relocate production to countries with weaker constraints, potentially raising global emissions.
Carbon neutrality
Carbon neutrality is the condition in which an entity's carbon dioxide emissions are balanced by equivalent removals or offsets, so the net contribution to the atmosphere is zero.
Carbon offset
A carbon offset is a certificate representing one tonne of CO2 or equivalent reduced, avoided, or sequestered by projects like forest protection and renewable energy, sold in voluntary and compliance markets.
Christiana Figueres
Christiana Figueres, born Karen Christiana Figueres Olsen in 1956, is a Costa Rican diplomat who led the UN climate convention and the 2015 Paris Agreement.
Cirrus cloud thinning
Cirrus cloud thinning is a proposed climate intervention that would seed high cirrus clouds so they thin and more heat escapes to space, cooling the planet.
Clean Development Mechanism
The Clean Development Mechanism (CDM) is a Kyoto Protocol carbon offset mechanism that lets developing-country projects earn credits industrialized countries use toward their emission targets.
Clean Power Plan
The Clean Power Plan was a 2015 EPA rule establishing state guidelines to cut carbon dioxide emissions from existing power plants; it was stayed, repealed, and never took effect.
Climate Action Tracker
The Climate Action Tracker (CAT) is an independent scientific project tracking government climate action against the Paris Agreement, run by Climate Analytics and NewClimate Institute since 2009.
Climate Analytics
Climate Analytics is a global climate science and policy institute founded in 2008 in Potsdam, Germany, and headquartered in Berlin, best known for the Climate Action Tracker project.
Climate and Clean Air Coalition
The Climate and Clean Air Coalition (CCAC) is a UNEP-convened partnership founded in 2012 to reduce short-lived climate pollutants such as methane and black carbon.
Climate Change Act 2008
The Climate Change Act 2008 is a UK law setting legally binding greenhouse gas emissions targets, five-yearly carbon budgets, and the Committee on Climate Change.
Climate Change Committee
The Climate Change Committee is the UK's independent statutory body, created by the Climate Change Act 2008, advising on emissions targets and reporting progress to Parliament.
Climate change in the Netherlands
Climate change in the Netherlands brings heat, drought, heavy rainfall, and sea level rise to a country where about a third of the land lies below sea level.
Climate change litigation
Climate change litigation, also called climate lawsuits, uses courts to force emissions cuts, compensation, or stronger climate policies, growing from 884 cases in 2017 to over 3,000 by 2025.
