Proposal to correct cross-references in UN R73. The amendments modify paragraphs 12.1, 15.1, and Annex 3, paragraph 2.4 to replace incorrect paragraph citations with accurate ones. The corrections address invalid references that do not exist or lack contextual relevance. The changes do not increase requirement stringency.

Proposal to correct cross-references in UN R73. The document amends paragraphs 12.1, 15.1, and Annex 3 paragraph 2.4 to correct invalid or non-existent paragraph references. Changes include updating references from paragraphs 12.4.4 and 15.2.4 to 12.4.2/3 and 15.2.2/3 respectively, and replacing the non-existent paragraph 2.8 reference with paragraph 12.10. The corrections do not increase requirement stringency.

This informal document GRSG-131-20 presents an artificial intelligence analysis of energy waste and CO2 generation by poorly insulated or uninsulated cars. The analysis compares cars with good roof insulation (metal roofs with 2-3 cm foam/felt) versus poor or no insulation (glass roofs or thin headliners) across 20,000 km annual driving. For gasoline cars, poor insulation wastes 70 L/year and generates 175 kg additional CO2. For electric vehicles, it wastes 200 kWh/year and generates 100 kg additional CO2. Across a weighted fleet, poor insulation costs $61 annually per car. Globally, approximately 600 million poorly insulated cars waste $36.6 billion annually and generate 91.2 million tons additional CO2 yearly.
