Management & Excellence...has produced again its annual list of the most sustainable oil and gas companies...The “compliance” scores of the companies, say M&E, are as follows: 1. Petrobras 92,25% 2. Total 91,21% 3. BP, StatoilHydro 89,15% 4. (empty due to above dual ranking) 5. Shell 87,86% 6. ENI 78,55% 7. Repsol 74,68% 8. OMV 73,39% 9. Chevron 72,87% 10. ConocoPhilips 72,35% 11. ExxonMobil 67,96% 12. Pemex 66,93% 13. Marathon 66,67% 14. Lukoil 55,81% 15. ENAP 40,31% 16. Gazprom 40,05% M&E makes its money from selling its research...M&E says that the companies are scored on “compliance” with “387 accepted international standards in sustainability, corporate governance, social responsibility, ethics and transparency”...It all sounds impressive. But such lists raise questions about whether one can make real, useful analysis of companies on this basis...That leaves aside the debate as to whether oil companies can even be called “sustainable” since they produce a non-renewable resource and invest little in renewable energy.
