Real-world carbon accounting and energy transition challenges
Quantitative analyses challenge simplistic zero-emission narratives: battery production emits 83.5 kg CO2/kWh; oil consumption growth continues. Renewable certificate accounting gap exposed by Google, Amazon, Microsoft emissions. Positive decoupling in EU. Keeling Curve 432.34 ppm. Energy Institute 2026 Statistical Review: global emissions record 41.0 Gt CO2e, up 1.1%. Barnard clarifies COP31 target is final energy, not useful energy. Queensland stopped reporting emissions. Ireland emissions down but gap remains. JRC hydrogen study challenges green hydrogen. JBS drops net zero target. TPI steel/mining carbon data. GHGRP legal limbo. Longi replaces silver with copper. IEA projects first oil demand decline since 2020. OPEC lowers 2026 oil demand growth forecast to 780,000 bpd. Climate attribution critique shows non-climate factors dominate. New decoupling evidence: 10 countries where green energy production outpaced electricity demand in 2025. EU ETS amendment proposal (50% reduction since 2005) but relaxation of reduction rates and increased free certificates from 2031. Ledger-based carbon accounting governance challenges. Global energy demand gap: 8.1 EJ growth vs 3.2 EJ from renewables. Hormuz closure analysis: 20 mb/d disruption, 1.1 billion barrel shortfall. Methane abatement in maritime shipping as policy opportunity. EU suspends methane law penalties for three years under US pressure and Hormuz disruptions. IRENA reports renewables grew 9.8% in 2024, reaching 31.7% of global electricity; 693 GW added in 2025. Fossil fuels still generate 57% of world electricity and 86% of primary energy. India's coal imports rebounded. IEA Electricity Mid-Year Update 2026: 3.6% demand growth, renewables overtaking coal by 2026, solar PV adding 600 TWh, Hormuz disruption driving coal switching. US emissions 4.9 Gt CO2 in 2025, up 2%, with coal generation rising 13% despite retirements. India electricity demand rebounded 7% in 2025, reaching 100 GW VRE milestone. OPEC long-term projections (32,017–59,500 TWh by 2050) with energy density arguments. Global coal use in 2025: record absolute consumption 166 EJ (+0.7%), declining share (27.7%), Asia 83.2%. Rhodium Group's Taking Stock 2026: US emissions 27-41% reduction by 2040 under current policy. China achieved first large-scale commercial delivery of green ammonia. Washington state emissions gap. New this cycle: China sets 17% CO2 intensity reduction target for 2030 vs 2025, coal power share below 50%, 1.95 TW wind+solar, 25% non-fossil target. Global GHG dataset (JRC) shows 53.2 Gt CO2eq in 2024, up 1.3%, EU27 35% reduction since 1990. IEA STEPS outlook projects 2.5% annual final consumption growth to 2035. China's battery model: 300 GW storage target, 70% cost drop, 90% global BESS share.
