Fossil vs FutureThis is Fossil vs Future, a warm conversation between generations on climate change. Author: James Cameron and Daisy Nicholls
This is Fossil vs Future, a warm conversation between generations on climate change. - Each podcast episode will be focusing on a different climate-related challenge, as godfather and goddaughter, James and Daisy, share their individual experiences and perspectives, with the hope of fostering understanding between generations. - James is at the later stage of his working life dedicated to dealing with climate change, through law, finance, and social entrepreneurship, and Daisy is at an earlier stage of her career, equally focused on the climate and how to drive systemic change through her experience in the finance, business, and non-profit sectors. - We want to use intergenerational dialogue as a tool to learn, inspire, and get stuff done! - LinkedIn https://www.linkedin.com/company/fossil-vs-future Instagram https://www.instagram.com/fossil_vs_future TikTok https://www.tiktok.com/@fossil_vs_future Language: en Genres: Earth Sciences, Nature, Science Contact email: Get it Feed URL: Get it iTunes ID: Get it |

WHAT ABOUT SUPER POLLUTANTS? A quick fix or an overlooked threat?
Episode 37
Tuesday, 17 March, 2026
Although we often focus on carbon dioxide, a group of powerful pollutants is also driving a large share of today’s warming… In this episode, James and Daisy talk about super pollutants. Why are they important? Why are they worse for the climate? How can we reduce their use? SOME RECOMMENDATIONS: The Global Methane Pledge (GMP) – Launched at COP26 by the EU and the US, the GMP now has 160 participants who agree to take voluntary actions to reduce global methane emissions by at least 30% from 2020 levels by 2030, potentially eliminating over 0.2ºC warming by 2050. Methane has caused 30% of warming since the Industrial Revolution.The Climate and Clean Air Coalition (CCAC) – A voluntary partnership of over 200 governments, intergovernmental organizations, businesses, scientific institutions and civil society organizations committed to protecting the climate and improving air quality by reducing short-lived super pollutants (methane, black carbon, tropospheric ozone and hydrofluorocarbons (HFCs)). The CCAC drives efforts to implement known practices and existing technologies that can achieve global reductions of at least 40% of methane by 2030 (vs 2010); 70% of black carbon by 2030 (vs 2010); and 99.5% of HFCs by 2050 (vs 2010).OTHER ADVOCATES AND RESOURCES:UNEP (2024) – Interactive cartoons explaining the science of super pollutants. UNEP – Parties to the Montreal Protocol (2016 Kigali Amendment) agreed to phase down HFCs by 80-85% by the late 2040s.CCAC (2024) – Super pollutants are a “flow” problem (controlling how fast the planet warms) whereas carbon dioxide is a “stock” problem (controlling the maximum extent of warming).CCAC – Methane has an atmospheric lifetime of 12 years (much shorter than CO2) but per unit of mass, has a warming effect 86x stronger than CO2 over 20 years and 28x over 100 years.UNEP – The International Methane Emissions Observatory (IMEO) launched the Methane Alert and Response System (MARS) at COP27– the first public global satellite detection system providing actionable methane emissions data.PR Newswire (2026) – A group of companies including Amazon, Autodesk, Figma, Google, JPMorganChase, Salesforce, and Workday announced a $100 million Superpollutant Action Initiative.Carbon Brief (2025) – Super pollutants are responsible for around 45% of global warming to date, as well as millions of premature deaths each year. Human-caused methane emissions come from: (1) Agriculture (~40%), such as from livestock and rice production; (2) Fossil fuels (~35%), as a by-product of fossil fuel extraction, storage and distribution; and (3) Waste (~20%), from food and other organic materials decaying in landfills and wastewater.UK Government (2025) – The UK’s Methane Action Plan notes that UK methane emissions have reduced by 62% between 1990 and 2023. IPCC (2023) – “Global Warming Potential (GWP) is an index measuring the radiative forcing following an emission of a unit mass of a given substance, accumulated over a chosen time horizon, relative to that of the reference substance, CO2.” National Grid (2025) – Sulphur hexafluoride (SF6) has a GWP of 24,300 and an atmospheric lifetime of 3,200 years. 80% of the SF6 used globally is in electricity transmission and distribution.European Commission – The EU Methane Regulation (EU/2024/1787) entered into force on 4 August 2024. It aims to reduce methane emissions into the atmosphere, both in the EU and in global supply chains, and to minimise leaks of methane by fossil energy companies operating in the EU.EMSA – From 1 January 2026, the EU Emissions Trading System (ETS) has incorporated methane and nitrous oxide for maritime transport.Thank you for listening!
