Overview
- TUM researchers presented a CirculaTUM literature review on September 1 that pooled 19 studies with 47 scenarios and found battery electric vehicles cut lifecycle CO₂ by an average of about 41 percent but ranged from an 89 percent reduction to a 21 percent increase depending on assumptions.
- The paper argues the EU’s current regulation counts only tailpipe emissions at fleet level and therefore hides production, battery manufacturing, electricity supply and recycling emissions that affect a vehicle’s true climate impact.
- Other TUM faculty and outside experts have criticized the white paper for being authored by a small team, lacking peer review, and giving too little weight to battery cell production, casting doubt on how strongly it should shape binding policy.
- Politicians and some industry actors quickly used the study to press for technology‑neutral, lifecycle rules—Bavarian leader Markus Söder cited the paper and reports link BMW as a private backer—while environmental groups note the majority of scenarios still favour BEVs.
- Independent DUH fleet data show a recent shift by several politicians from full EVs to plug‑in hybrids that raises official fleet CO₂ and underlines that real‑world use patterns and certification costs would matter if Brussels adopts lifecycle reporting during the upcoming Automotive Package negotiations.
