Our operations' contributions

By carefully and thoughtfully increasing efficiency and reducing emissions and waste, we are enabling a better future. Through the diligent application of our Operations Integrity Management System (OIMS), our employees continually seek new ways to improve our manufacturing facilities, offices and logistics operations in the key areas below.


This section provides details on the environmental performance of ExxonMobil's Chemical business. For additional information on our social and economic contributions and environmental data from other parts of the corporation, see our Corporate Citizenship Report.


Health & safety

Safety is more than a priority within our organization; it is a core value and an integral part of our culture. Protecting the safety and health of our workforce, and the communities in which we operate, is fundamental to our business. Our goal is “Nobody Gets Hurt” and we will never stop working towards it.


Taking a proactive approach to safety rooted in our OIMS builds layers of protection into our operations and processes to help prevent harmful incidents. In 2016, we had the lowest number of high-potential process safety incidents and the lowest number of injuries to our workforce — in our history. There were just six recordable injuries to employees and there were no lost time injuries to any of our 11,000 employees. In fact, we are coming up on four years without a lost time injury to any of our employees. In 2016, the lost time incident rate (LTIR) was 79% lower than the 10-year annual average from 2007 to 2016.



Emissions reduction

We believe the risk of climate change warrants action by businesses, governments and consumers, so we all need to do our part to make meaningful progress. As part of our contributions to managing these risks, aiming to reduce greenhouse gas (GHG) emissions and volatile organic compounds (VOCs), sulfur dioxide (SO₂) and nitrogen oxides (NOx) is a key focus. Cost-effective new technologies and new operating practices are at the core of our operational efforts.For short-term success, our Global Energy Management System (GEMS), a tool within OIMS, identifies energy saving and emission reduction opportunities.


For the mid-term, we deploy highly effective, proven cogeneration technology, while research programs focus on emissions reduction for the longer-term. 


As a result of our activities, net equity GHG emission intensity (metric tons/100 tons of production) in 2016 has fallen 9% across our Chemical business, compared to the 10-year annual average from 2007 to 2016. Since 2013, net equity GHG emission intensity is down almost 9%.

In 2016, the Chemical business reduced VOC emission intensity by 21% from a 10 year annual average of 0.34 to 0.27 metric tons per 1000 metric tons of production.

Combined VOC, NOx and SOx emission intensity was down 7% from a 10-year annual average of 0.74 to 0.69 metric tons per 1000 metric tons of production (For detailed VOC, NOx and SOx emission data see the Corporate Citizenship Report.)


Flaring at our Chemical manufacturing operations in 2016 has dropped 9% compared to the 5-year annual average between 2012 and 2016.


Energy use

GEMS has helped us generate relative energy efficiency improvements over the years. Between 2006 and 2016, energy intensity in our global Chemical manufacturing operations has decreased 4%, while production has increased during this time frame.

ExxonMobil is a vertically integrated corporation, affording unique opportunities to maximize operational efficiency by controlling factors like waste heat, and sharing resources / infrastructure. For example, incorporation of cogeneration into ExxonMobil’s manufacturing facilities has played a major role in delivering significant energy efficiency opportunities.

Since 2001, ExxonMobil has invested more than $2 billion in cogeneration projects and continues to develop additional opportunities which will save energy and reduce emissions. We also invested $2 billion since 2000 at our refining and chemical facilities around the world.

Over the past decade ExxonMobil has added more than 1,000 megawatts of cogeneration capacity and continue to develop additional investment opportunities (see the Corporate Citizenship Report). With interests in more than 100 installations at more than 30 locations around the world, the approximate 5,500 megawatts of cogeneration capacity is equivalent to the annual energy needs of 2.5 million U.S. homes.

Water use


Because it is limited and we recognize some of ExxonMobil’s operations can use significant amounts of water, we are committed to being efficient with every aspect of water use — our withdrawals, consumption and discharges. Carefully managing water resources, we use the same systems, processes and policies that govern our overall approach to environmental management (see OIMS). Where appropriate, we use alternative water sources and seek opportunities to reduce, reuse and recycle water. For more information on water, see our Corporate water overview.


The amount of freshwater consumed (metric tons/100 tons of production) by the Chemical business in 2016 decreased by 25% compared to the 10-year annual average from 2007-2016.

Local water management efforts at our Chemical manufacturing sites contribute to the decline in our water consumption.

Waste reduction

Within our sustainability programs is a commitment to reduce our footprint of both non-hazardous and hazardous waste across the Chemical business. Our actions have resulted in our total net waste (metric tons/1000 tons of production) falling by 8% in 2016 compared to the 10-year annual average between 2007 and 2016. This reduction is primarily due to the installation of new waste-water treatment capabilities at our Singapore facility. We monitor our progress and continually seek ways to make further reductions.


Socio-economic contributions

Committed to operating in a manner that is both environmentally and socially responsible includes addressing social and economic needs to ensure stronger futures for the communities where we work. Striving to have a lasting, positive effect on local communities we provide direct and indirect economic benefits by creating new jobs, developing a technically skilled workforce and purchasing local goods and services.

ExxonMobil has an integrated contribution program across the corporation to help us maximize the impact of our social and economic development programs. In 2016, ExxonMobil contributed over $242 million to communities around the world with the majority of spending focused on our signature, corporate-led initiatives to improve education, combat malaria and advance economic opportunities for women. Additionally, we supplement our corporate-led initiatives with local, community-specific initiatives that range from workforce development efforts to responding to natural disasters (see the Corporate Citizenship Report for more information).
