Climate economists are typically obsessed with\u00a0modeling,\u00a0pricing\u00a0and reducing\u00a0a specific molecule: carbon\u00a0dioxide.\u00a0Carbon\u00a0dioxide\u00a0pollution is the original villain that drives climate change and the extreme weather impacts that are already shocking our world.\u00a0\u00a0But beyond carbon dioxide, other polluting culprits behind climate change are rightfully getting increasing and urgent attention: methane and other superpollutants. It leaves an economist asking: how do we price actions on superpollutants to make sure we’re creating the biggest climate benefits with every dollar?<\/p>\n\n\n\n

In my last blog post<\/a>, I\u00a0proposed\u00a0pulling nature into the world\u2019s\u00a0compliance\u00a0carbon markets\u00a0as a\u00a0major opportunity\u00a0to\u00a0start\u00a0eliminating\u00a0the 53\u00a0billion tons of climate\u00a0pollution we need to cut<\/strong>.\u00a0\u00a0Protecting and restoring\u00a0nature\u00a0helps us store\u00a0more\u00a0carbon, and\u00a0release\u00a0less of it\u00a0into our atmosphere\u00a0where it would\u00a0fuel\u00a0climate change.\u00a0This is a\u00a0long-term\u00a0investment in a more stable, safe future:\u00a0Removing\u00a0even a single\u00a0ton of carbon\u00a0dioxide\u00a0from the atmosphere\u00a0today\u00a0delivers\u00a0benefits\u00a0for\u00a0over a century or more.\u00a0\u00a0\u00a0<\/p>\n\n\n\n

But we\u2019re already seeing the impacts of a warming world today, such as the extreme weather we are anticipating from a strong El Ni\u00f1o season<\/a> this summer. As climate damages mount, and affordability looms large, the world is hungry for near-term, cost-effective climate solutions that can tackle warming immediately. <\/p>\n\n\n\n

Enter\u00a0superpollutants\u00a0like methane\u00a0(natural gas),\u00a0hydrofluorocarbon (HFCs used in refrigerants and coolants)\u00a0and\u00a0black carbon\u00a0(soot).\u00a0These lesser-known pollutants also cause\u00a0climate change, but\u00a0on a different timeline\u00a0than carbon.\u00a0For example, emitting one ton of methane has about 80 times the warming effect as one ton of carbon\u00a0over a\u00a020-year\u00a0period.\u00a0But the warming effects of methane die off in a matter of decades,\u00a0whereas\u00a0the effects of carbon linger for\u00a0centuries.\u00a0<\/p>\n\n\n\n

Most\u00a0superpollutants\u00a0have\u00a0a similar pattern:\u00a0severe short-term effects, but those effects\u00a0die off\u00a0rapidly.\u00a0This is helpful to know because the\u00a0reverse is also true: Avoiding emissions of\u00a0superpollutants\u00a0can have rapid cooling effects, so cutting\u00a0them\u00a0is one of the fastest, most reliable ways to slow warming in our\u00a0own\u00a0lifetimes.\u00a0<\/p>\n\n\n\n

We have the technology to make these reductions, so why haven\u2019t we scaled these\u00a0solutions\u00a0already?<\/strong> In many cases, we know how to find methane leaks, recover refrigerants, reduce\u00a0soot\u00a0and improve inefficient systems. The harder problem is economic: our markets and accounting systems do not yet consistently tell investors,\u00a0companies\u00a0and governments how to compare a ton of methane or HFC reductions with a ton of carbon dioxide reductions.\u00a0Such an \u201cexchange rate\u201d between these pollutants is\u00a0essential\u00a0for building\u00a0superpollutants\u00a0into markets.\u00a0<\/p>\n\n\n\n

This observation raises a couple of important questions:\u00a0<\/p>\n\n\n\n

How important is it to cut\u00a0superpollutants?\u00a0<\/strong><\/h2>\n\n\n\n

Or, more precisely, how much effort should\u00a0we\u00a0devote\u00a0to cutting\u00a0superpollutants\u00a0versus carbon\u00a0dioxide?\u00a0<\/strong><\/p>\n\n\n\n

We can rely on decades of\u00a0economics\u00a0research\u00a0telling us how much harm is avoided by\u00a0cutting\u00a0a ton of pollution.\u00a0The data shows that\u00a0cutting a ton of carbon\u00a0dioxide avoids around $200<\/a>\u00a0in\u00a0harm (accounting for the benefits\u00a0over time), and cutting a ton of methane avoids around $4,000<\/a> in harm\u00a0(similarly accounting for the benefits over time).\u00a0Values like these can help companies, governments, and even households make decisions about where\u00a0to maximize their climate impact.\u00a0\u00a0\u00a0<\/p>\n\n\n\n

How much progress can we expect to make if we tackle\u00a0superpollutants?\u00a0\u00a0<\/strong><\/h2>\n\n\n\n

Today,\u00a0methane and other superpollutants are causing about 45 percent of warming<\/a>. If we were to completely cut away superpollutants, we could\u00a0reduce our\u00a053\u00a0billion\u00a0ton\u00a0pollution\u00a0problem down\u00a0by about 13\u00a0billion tons<\/a>.\u00a0That\u2019s\u00a0a huge contribution \u2013 larger than all emissions from the US and Europe combined<\/a> \u2013 and\u00a0it would rapidly cool the planet.\u00a0Reducing\u00a0superpollutants\u00a0gives us an immediate edge in the fight against climate change by slowing warming in the next five to ten years. This could help us avert near-term economic losses from climate impacts, while buying us time to decarbonize harder sectors like heavy industry and aviation.\u00a0<\/p>\n\n\n\n

One hugely beneficial feature of superpollutants is that, generally speaking, people aren\u2019t emitting them on purpose.  A huge fraction of methane and HFC pollution are leaking at oil and gas facilities and infrastructure or cooling and refrigeration systems. If we can find the leaks (for example, with new sensors and satellites), we can often fix them easily.  <\/p>\n\n\n\n

How can we accurately price superpollutants in compliance carbon markets?<\/h2>\n\n\n\n

An economist would say that the hardest challenge in bringing\u00a0superpollutants\u00a0into compliance markets is not whether they matter, but how we can value them correctly.\u00a0<\/strong>Carbon markets were built around carbon dioxide, which stays in the atmosphere for\u00a0a very long\u00a0time.\u00a0But because\u00a0superpollutants\u00a0cause damage on\u00a0a very different\u00a0timescale, we\u00a0cannot\u00a0simply\u00a0“price\u201d\u00a0a ton of methane or an\u00a0HFC\u00a0the same way we\u00a0price\u00a0a ton of carbon dioxide. We also should not rely on shortcuts that capture only part of the story.\u00a0<\/p>\n\n\n\n

One\u00a0approach is to ask a practical question: how much climate damage do we avoid when we reduce one pollutant compared with another? That framing allows us to value reductions based on their real-world benefits, including timing,\u00a0scale\u00a0and avoided harm, rather than relying only on physical warming metrics\u00a0over arbitrary\u00a0time-scales.\u00a0<\/p>\n\n\n\n

\"\"<\/a>
The dairy aisle in your grocery store represents a range of superpollutants: Dairy cows and cattle burp out methane; meanwhile, refrigerant super pollutants are human-made gases like hydrofluorocarbons (HFCs) used in air conditioning and refrigeration. <\/figcaption><\/figure>\n\n\n\n

Getting\u00a0this right matters\u00a0because markets need a common yardstick. Companies, governments,\u00a0philanthropies\u00a0and investors are increasingly looking for climate solutions that are fast,\u00a0measurable\u00a0and cost-effective. But without a clearer way to compare\u00a0different kinds\u00a0of pollution reductions, capital will not always flow to\u00a0solutions\u00a0that can deliver the greatest benefit per dollar.\u00a0That is the beauty of bringing\u00a0superpollutants\u00a0more fully into compliance markets. <\/p>\n\n\n\n

Where carbon markets already exist, we should create ways for high-quality\u00a0superpollutant\u00a0reductions to be valued alongside carbon\u00a0dioxide\u00a0reductions using economically sound methods. <\/strong>Where markets do not yet exist,\u00a0exchange-rate pricing\u00a0can help decision-makers compare options and\u00a0identify\u00a0the most cost-effective opportunities.\u00a0<\/p>\n\n\n\n

The scale of the opportunity is significant. Our preliminary evidence suggests that up to 7 gigatons of\u00a0superpollutant\u00a0reductions, on a CO\u2082-equivalent basis, could be achieved globally at or below a reasonable benchmark price. That is why getting the economics right matters: it can help direct money toward the fastest, most affordable reductions available now.\u00a0<\/p>\n\n\n\n

The idea is\u00a0simple. The\u00a0world needs to cut climate pollution quickly and\u00a0affordably\u00a0so\u00a0we need a way to compare\u00a0very different\u00a0solutions on common terms. That does not mean treating every pollutant\u00a0the same. It means valuing each reduction in a way that reflects the damage it avoids and the speed at which it helps.\u00a0<\/p>\n\n\n\n

There\u2019s\u00a0growing demand\u2014especially from big tech and global consumer brands\u2014to invest in climate solutions with\u00a0immediate, measurable impact. <\/p>\n\n\n\n

Addressing\u00a0superpollutants\u00a0is attractive because: <\/p>\n\n\n\n

    \n
  • they can move ahead outside of direct regulation<\/li>\n\n\n\n
  • they are amenable to inclusion in compliance carbon markets<\/li>\n\n\n\n
  • generally speaking, these emissions are unintentional and avoidable<\/li>\n\n\n\n
  • we now have the technology to \u201csee\u201d them with cameras and satellites<\/li>\n\n\n\n
  • their\u00a0avoided harm is often 20 times larger than\u00a0that for carbon dioxide<\/li>\n\n\n\n
  • the right\u00a0economically-grounded\u00a0exchange rates\u00a0can help us\u00a0maximize our climate progress per dollar spent.\u00a0\u00a0<\/li>\n<\/ul>\n\n\n\n

    EDF and our academic partners are building exactly the framework the world needs right now: A blueprint grounded in science and economics for pricing, valuing, and investing in the most powerful climate solutions available, including\u00a0ones to address\u00a0superpollutants.\u00a0We believe that by taking this surgical, rigorous,\u00a0“Moneyball”\u00a0style\u00a0approach to climate\u00a0action,\u00a0we will make rapid, lasting climate solutions that\u00a0support\u00a0economic\u00a0growth\u00a0and\u00a0don\u2019t\u00a0break the bank.\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"
