The prospect for electric vehicles (EVs) as a climate change solution hinges on their widespread adoption across political lines. This paper uses county-level data from 2012-2023, to see if there are trends in EV ownership based on political party. Read the paper & brief here: ceepr.link/46AJNsU

They propose regulatory solutions to better align capacity procurement costs and benefits, such as sharing capacity costs at regional level.

MIT Center for Energy and Environmental Policy Research @mitceepr.bsky.social · 18/08/2026
This creates a misalignment: each country does not pay exactly for the capacity it eventually benefits from. The authors of this paper find that this misalignment can encourage free riding and lead to underinvestment in capacity at the regional level.

For regulators and market operators, the takeaway is that periodic reassessment of zone configurations may be a relatively low-cost way to improve market efficiency as grid conditions continue to evolve.

MIT Center for Energy and Environmental Policy Research @mitceepr.bsky.social · 27/07/2026
In this paper, we develop a framework to measure this misalignment and identify better zone configurations. Applying it to three major U.S. markets, we find that existing zones leave meaningful efficiency gains unrealized, particularly in California.

How CBAM recognizes carbon prices paid abroad will shape its effectiveness against leakage and catalyze carbon pricing abroad. Since CBAM is not meant to be a revenue-raising tool, it can make sense to let trade partners close the EU ETS price gap and retain revenues at home.

Pump prices are ⬆️ but suspending federal gas tax likely won’t help much. Prof. Gilbert Metcalf says: • Gas/diesel taxes are small vs. 40%+ fuel price hikes • Farmers are already exempt • It could boost demand, raising prices • The tax brings in ~$3.5B/month, needed to quell deficit

While the authors examine only a subset of climate-related impacts, the evidence suggests that recent climate change now imposes an average cost between $400 and $900 per household annually depending on attribution assumptions, with the hardest-hit counties exceeding $1,300 per household.

CA Senate Bill 846 authorized a potential 5-year extension from 2025 to 2030. However, on 4/2/2026 the Nuclear Regulatory Commission approved a 20-year license extension to 2045.

The misalignment between system benefits & current investments may reflect a rational response to deep uncertainty - yet it may perpetuate a high-risk, high-reward paradox typical of breakthrough tech. This ambiguity calls for a more deliberate evaluation of fusion’s role in future energy systems.

Using a high-resolution energy system model (PyPSA-Eur) and a probabilistic valuation framework, the authors' findings indicate that the later fusion becomes available, the greater will be the demands on its economic competitiveness and the need for early integration into energy system planning.

This research commentary contributes to the debate by means of a review of the history of an analogous debate in corporate financial accounting standards, which can be helpful for identifying lessons that can instruct the discussion on inventory and consequential accounting for Scope 2 emissions.

MIT Center for Energy and Environmental Policy Research @mitceepr.bsky.social · 03/02/2026
Currently, the Protocol's metrics attempt to inventory emissions directly attributable to the company’s electric load, subject to the constraints of available data. A competing alternative, known as ‘consequential’ or ‘impact accounting’, looks beyond the boundary of the company’s own operations.
