Preventing runaway climate change by mitigating emissions of super greenhouse gases – hydrofluorocarbons (HFCs)
Through a global phase-down of HFCs we have the opportunity and the obligation to mitigate 100 billion CO2 equivalent metric tons by 2050.
EIA's Climate Campaign focuses on international and domestic policies to phase-down hydrofluorocarbons (HFCs) - potent greenhouse gases (GHGs) used primarily in refrigeration, air conditioning, and foam applications. As part of our work, we have undertaken groundbreaking investigations into the illegal trade in ozone depleting substances (ODS) and have been closely involved in international ozone and climate negotiations for more than a decade.
HFCs were developed as replacement chemicals for ODS (CFCs - chlorofluorocarbons and HCFCs - hydrochlorofluorocarbons), which have been or are currently being phased-out under the Montreal Protocol. Unfortunately, HFCs have huge global warming potentials (GWPs) and are several thousands of times more damaging to the climate than CO2. If left unchecked, HFC emissions will continue to increase exponentially and could constitute up to 19% of all greenhouse gas emissions by 2050, potentially negating a significant amount of climate change mitigation actions pledged by countries to date under the 2015 Paris Agreement of the United Nations Framework Convention on Climate Change (UNFCCC).
Phasing down HFCs under the Montreal Protocol is the most cost-effective, short-term and fast-action strategy for reducing GHG emissions. A global phase-down could avoid 1.1–1.7 billion metric tons CO2 equivalent (CO2 equivalent is a measure used to compare impacts of greenhouse gases based on their global warming potential in relation to CO2) of GHG emissions per year by 2030, with cumulative emission reductions of nearly 100 billion metric tons CO2 equivalent by 2050.
Fortunately, HFC-free technologies are available to enable a phase-down of HFCs and replace these dangerous, climate-damaging chemicals. Rapid large-scale transitions to HFC-free alternatives is not only possible but also critical to protect the climate.
EIA's Total Impact on Protecting the Climate
EIA's Forest Campaign is also crucial to protecting the world's climate. Deforestation and forest degradation releases carbon dioxide (CO2) into the atmosphere and dramatically reduces the capacity of ecosystems to adapt to climate change. Healthy natural forests store vast amounts of carbon and are the most resilient to climate change and other disturbances. An independent report estimates that the push to stop illegal logging globally, which has been led by EIA, already saved 17 million hectares (42 million acres) from deforestation and forest degradation between 2002 and 2010, totaling between an estimated 1.2 and 14.6 billion metric tons of avoided carbon emissions.
Between phasing out HFCs via a global agreement under the Montreal Protocol and defending the governance of the global forests from illegal logging, these two EIA campaigns will combine to cut about half of all projected GHG emissions in 2050.

- Facilitate broad market uptake of HFC-free alternatives
- Maximizing energy efficiency co-benefits
- Raise awareness of available HFC-free alternatives
- Ensuring direct transitions to lowest-GWP alternatives
- Broaden stakeholder engagement in standards development
- Accelerate adoption of updated standards, particularly in the U.S.
- Remove market barriers posed by obsolete standards
