🗞️ Driving the news: The U.S. Department of Energy (DOE) is revising the Social Cost of Carbon (SCC) as part of new energy standards for commercial refrigerators
This move highlights broader concerns about how the SCC is used in policy decisions, with critics arguing that it is based on subjective welfare measures, not clear economic costs

🔭 The context: The SCC attempts to quantify the future impacts of CO2 emissions, but its reliance on welfare-based calculations, rather than dollar-based economic measures, introduces confusion
Critics argue that the methodology distorts the results by focusing on theoretical benefits across generations

🌍 Why it matters for the planet: The SCC’s flaws can lead to misguided climate policies, which may overestimate or underestimate the actual economic impact of carbon emissions and hinder effective long-term climate action

⏭️ What's next: Economists suggest shifting to a more transparent metric, such as GDP impact, to better align policy with measurable economic outcomes, avoiding subjective welfare estimates

💬 One quote: "The SCC calculations... would seem to violate [the] principle" of rational relationship to real-world impacts, argues James Broughel

📈 One stat: The current U.S. government estimate for the social cost of carbon is approximately $51 per metric ton of CO2, though some suggest raising it to as high as $190 to reflect more recent climate impact data
