ExxonMobil, the world’s largest company by both revenue and market capitalization, has a place on the world stage comparable to a major nation-state (only 23 nations in 2006 had a GDP greater than Exxon’s revenues of $347 billion, which rose 7% in 2007). Only 31 nations exceeded its annual greenhouse gas emissions in 2004 [UN MDG indicators, ExxonMobil CDP response]. If end-use emissions of ExxonMobil’s products are included, its carbon footprint of 1 billion metric tons of CO2 equivalent is exceeded only by five nations.
David Sassoon at Solve Climate asked Mario Lopez-Alcala, a senior analyst with Innovest Strategic Value Advisors, to estimate how the Kyoto Protocol impacts the company. Lopez-Alcala made some counter-intuitive discoveries.
Turns out that under Kyoto, Exxon is responsible for abating only 9 million out of the 138 million tons of its carbon footprint—about 6.9% of its absolute exposure. Mario arrived at this figure by compiling a weighted average of the emissions targets affecting all Exxon operations around the world. His estimate for what it costs Exxon to abate those emissions, assuming it had to purchase carbon credits? About $1 billion a year. (He calculated net present value for the 2008-2012 Kyoto compliance period and applied a standard oil industry discount rate to arrive at the figure, based on an expected price of $28 per ton of carbon. He also had to add in to the calculation, abatement costs for reducing emissions to a baseline year.)
$1 billion annually is not a terribly large liability for a $400 billion company.
Furthermore:
There’s also another aspect to Exxon’s carbon footprint: the 129 million tons of emissions that it is not required to reduce. It is an enormous carbon asset in a world in which carbon has a price, and it presents a tangible opportunity for enhancing profitability – even beyond $40.6 billion. By reducing those emissions – most simply through reduced flaring, co-generation, heat recuperation, and carbon capture and sequestration – Exxon could reap profits from selling carbon credits it generates. Mario reports that BP is the leader in the sector in taking advantage of these opportunities, which are tangible and positive already.
Sassoon concludes that from an investor (as well as moral) standpoint, ExxonMobil’s storied resistance to the science of climate change is a poor corporate position.
