Isometric is expanding, bringing our scientific rigor and transparency to certifying superpollutant destruction credits. Today, we’re announcing the development of two new protocols for the destruction of landfill methane emissions and hydrofluorocarbons (HFCs).
Superpollutants—a category that includes methane, hydrofluorocarbons (HFCs), and nitrous oxide—are greenhouse gases with global warming potentials far greater than carbon dioxide. Methane alone is around 80 times more potent than carbon dioxide, and together these gases are responsible for up to 45% of human-caused global warming to date.
Reducing superpollutant emissions could lower global temperatures by 0.5°C by 2050 and by 1°C by 2100. Tackling these gases helps avoid the most severe near-term impacts of climate change while buying time to deploy and scale other critical solutions, including renewable energy and carbon removal.
Superpollutant destruction is a crucial but underdeveloped part of the climate solution. Isometric is entering this market to bring the same scientific rigour and transparency that underpin our work in carbon removal—ensuring that every credit represents real, measurable climate impact.
As part of this expansion, Isometric will develop protocols for the destruction of landfill methane emissions and HFCs. These new protocols will be developed through collaboration between Isometric’s in-house Science Team and reviewers from its independent Science Network, which includes more than 300 scientific experts and practitioners.
Recoolit, a pioneer in refrigerant collection and destruction, partnered with Google in May 2025 to destroy 250,000 tonnes (in carbon dioxide equivalent) of superpollutants.
Louis Potok, CEO of Recoolit, said:
“We are delighted that Isometric will be bringing rigorous, tech-enabled verification to the destruction of superpollutants. This is a critical area for achieving near term climate impact, and we are excited to partner with them on bringing trust and scale to this industry.”
Cool Effect, a California-based non-profit, supports landfill gas projects that collect and destroy methane generated by waste. Cool Effect also partnered with Google earlier this year to install methane destruction equipment at a landfill in Cuiabá, Brazil.
Jodi Manning, CEO of Cool Effect, said:
“This decision by Isometric underscores the urgency of tackling superpollutants such as methane. Isometric has built an excellent reputation for scientific rigor and we look forward to working closely with them as they develop their protocol for the destruction of landfill methane emissions”.
Earlier this year, Isometric, Google, and Vaulted Deep announced a research partnership to explore how methane emissions eliminated by Vaulted can be quantified.
Randy Spock, Carbon Credits and Removals Lead at Google, said:
“Our program combines superpollutant elimination with carbon removal because it’s scientifically clear that the planet needs both. We’re excited to see Isometric take the same path, and expect that their expansion of rigorous measurement and scientific standard-setting from carbon removal to superpollutants will help the world unleash progress against the most powerful drivers of near-term warming.”
All superpollutant credits issued by Isometric will meet the same core requirements for additionality, conservative quantification, and independent verification that underpin its carbon removal credits.
