Abstract:
State-owned enterprises (SOEs) play a major role in the production of goods and services across many of the world’s largest economies, particularly in electricity generation, oil and gas, and heavy industry. SOEs (defined in this report as companies for which 50 percent or more of voting shares are held by a government) are also major sources of greenhouse gas emissions. The governments that control these SOEs are also signatories to the Paris Agreement on climate change. State ownership provides these governments with a major direct point of control over the climate and energy outcomes of these companies, both in terms of reducing emissions and directing future investment into low-carbon technologies and infrastructure. Improving the measurement of SOEs’ contribution to both national and global-level emissions provides important information to help understand to what extent SOEs should be targeted and to design strategies to maximize their potential role in the broader energy transition. This report provides an accounting of direct emissions associated with SOEs globally. It is challenging to comprehensively identify every SOE, as the total is estimated at well over 100,000. In addition, most identified SOEs do not disclose their emissions nor are estimates of these emissions available in the public domain. Despite these limitations, data compiled for this report covering almost 300 major SOEs suggest that SOEs globally are responsible for at least 7.49 gigatons of carbon dioxide equivalent (GtCO2e) annually in direct (Scope 1) emissions. While the true scale of SOE-related emissions is likely to be substantially higher, particularly when accounting for national oil companies and iron and steel manufacturers that do not currently report their emissions, this figure is over 1 GtCO2e greater than various previous estimates, and larger than the total annual emissions of any country except China.

Abstract:
Corporate pledges to purchase renewable electricity have led to significant new solar and wind capacity investments and driven down the carbon intensity of the power sector in the United States. Participating companies have increasingly procured this power, many with a goal of procuring quantities that are equal or proportional to the amount of electricity that they consume at their facilities on an annual basis.[1] Corporate buyers can reap many benefits from renewables procurement, including hedging against power price fluctuations and enjoying positive brand association, helping them meet shareholder demands around climate or other environmental, social, and governance (ESG) goals. However, the reality is that commitments to buy 100 percent renewable electricity may not equate to a company actually reducing its power carbon footprint to zero. This report from Columbia University’s Center on Global Energy Policy quantifies the mismatch between companies’ contracted variable renewable electricity (VRE) and their actual use of electricity to highlight the degree to which these companies still rely on a partially fossil-fueled power grid to bridge the gap. A modeling exercise and analysis done in collaboration with The NorthBridge Group reveals a significant shortfall between electricity demand and VRE supply, leaving companies that contract for 100 percent renewables to in fact draw between 20 percent and 50 percent[2] of their annual electricity from the regional electric grid, depending on their location, demand profile, and mix of contracted renewable supplies. This disparity presents a number of challenges to corporations that wish to achieve deep decarbonization and are unable to curtail operations to match renewable energy supplies. There are several approaches to get closer to a true zero-carbon power footprint. Installing storage capacity either on-site or at the power plant to provide stored electricity when renewables are not sufficient, such as with a battery,[3] is one option. However, this only reduces the minimum shortfall by half, requiring a customer to continue to rely on electricity from the regional electric grid for 10 percent to 28 percent of its annual load.[4] Resolving the shortfall by procuring extra renewable power (e.g., to 150 percent of annual electricity demand with renewables) can drive costs up substantially without closing the gap.
