1. In a GREAT paper (why isn't it published??), Anthoff, Dennig & @johannesemm.bsky.social show that most IAMs have a hidden goal of a uniform price and define Negishi weights to arrive at that goal. Yet, carbon price should grow at the discount rate (at least under a carbon budget constraint)...

Agreed. Socioeconomically optimal values have been found at roughly 83%. And even then, political and social implications need to be anticipated and addressed.
NB: Even the 55% target has not yet been digested. We found people believe the EU will only manage 43% by 2030. More Credibility is needed.

Results: By 2050, direct CO₂ emissions drop ~65% in buildings & ~70% in transport (vs. current policies).

Demand-side strategies provide climate benefits!

🚀 Want to meet the Paris Agreement goals? Reducing energy demand in buildings & transport is key!

🔎 Our latest study quantifies how demand-side strategies complement low-carbon supply-side solutions.

Excited to announce a new @pnas.org publication on the Social Cost of Carbon. We integrate evidence from the literature and expert survey to provide an SCC distribution inclusive of both parametric and structural uncertainties. Our mean 2020 value is $283 per ton CO2

Synthesis of evidence yields high social cost of carbon due to structural model variation and uncertainties | PNAS

Estimating the cost to society from a ton of CO2—termed the social cost of carbon (SCC)—requires connecting a model of the climate system with a re...

A vicious cycle of global warming, climate extremes, higher energy demand (esp. for cooling), thus further emissions and warming makes early-on mitigation even more important. Check out our new paper with @FranPieC @edecian @jackjackk1

The EU's ambitious #FitFor55 package deserves great attention (see, e.g., the detailed comments by @Tagliapietra_S). But how fair is the target itself globally? Based on works led by @Hel1vs and @nicolejvdb @nlenvironagency @EIEEorg et al., the #EU target for 2030 is..

#BeyondGDP is an important concept. Can #happiness or subjective well-being based on surveys provide an indicator at the macro level? We argue it might, finding strong economic, environmental and social explanatory variables drivers. and SSP simulations.
