Air 

The major airborne emissions generated by Neste Oil's refining operations comprise carbon dioxide, nitrogen oxides, sulfur dioxide, volatile organic hydrocarbons, and particulates.

Direct, indirect, and consequential carbon dioxide emissions

The majority of Neste Oil's direct emissions (scope 1) of CO2 are refining-related and generated at the Porvoo refinery. Refining-related CO2 emissions are largely formed in energy generation, coke combustion, when burning fuel in fired heaters and in hydrogen production. Indirect CO2 emissions (scope 2) are mainly produced when consuming grid electricity that Neste Oil buys to power its operations. The majority of the company's scope 3 emissions, not included in the direct or in-direct CO2 emissions, are related to the end use of products sold by Neste Oil and the goods and services the company purchases.

* Purchased goods and services: The calculation includes fossil and renewable raw materials used in Neste Oil’s production. The largest single source of feedstock-related greenhouse gas emissions comes from the production of the crude oil that Neste Oil buys. Secondary data was used to determine emission coefficients for crude oil and hydrogen. Other emission figures are based on actual emission coefficients, in accordance with the requirements of the Renewable Energy Directive (2009/28/EC). Emissions related to bought-in services and chemicals are not included in the figure. The emissions from services is considered low. The calculations of chemical-related emissions will be developed in the future.

** Use of sold of products: The calculation includes emissions generated during the use of products Neste Oil has sold from its own production. The calculation does not cover emissions generated during the use of products Neste Oil has bought and retailed. The majority of traffic fuel-related greenhouse gas emissions are generated when fuels are used in traffic.

*** End of life treatment of sold products: The calculation includes emissions generated during the end of life treatment of solvents, lubricants, and naphtha produced by Neste Oil. Literary sources have been used as end-of-life emission factors.

Increasing amount of CO2 captured

Neste Oil's Porvoo refinery captures CO2 produced during the refining process and sells the gas to a company located in the industrial area. A total of 131,000 (156,000) tons of CO2 was recovered in 2014.

In 2014, we also started up the construction of a CO2 capture and liquefaction unit at our renewable diesel refinery in Singapore. The unit is due for completion at the end of 2015. Once the plant is complete, it will process 40,000 tons of CO2-rich gas to the capture unit.

Considerably less volatile organic compound emissions to air

A vapor recovery unit was commissioned at the Porvoo refinery harbor at the beginning of 2014, making it possible to recover volatile organic compounds (VOC) released into the air during the loading of light products. The vapor recovery unit will cut Porvoo harbor VOC emissions to approximately one-third. As a result of the lower emissions, the employees of the harbor will also have a healthier working environment. The diffuse VOC emissions monitored at Rotterdam refinery were very low in 2014.

Reducing NOx emissions succeeded at Porvoo refinery

Nitrogen oxide (NOx) emissions from Neste Oil's refining operations during 2014 were 2,400 tons and sulfur dioxide emissions (SO2) 6,600 tons. Measurements did not identify any cases where threshold limits were exceeded.

The Porvoo and Naantali refineries, which concentrate on conventional oil refining operations, are Neste Oil’s only major sources of sulfur dioxide emissions. At the refineries, sulfur dioxide emissions are controlled and reduced by recovery plants and by using gas rather than oil in furnaces and fired heaters.

Catalyst changes succeeded in reducing NOx emissions by approximately 70% in the gasoline production unit at Porvoo refinery. The gasoline production unit is one of the largest individual sources of NOx emissions at Porvoo refinery, so the achieved reduction in emissions is also significant from the point of view of the overall emissions of Porvoo refinery.

SO2 emissions from the Naantali refinery can be monitored with the analyzers that are installed in the main stacks. Due to the low utilization rate of the refinery, SO2 emissions were low in 2014.

Air quality measurement system renewed in Porvoo

Neste Oil monitors ambient air quality throughout the Kilpilahti area. Air quality measurements are made at three measurement stations in the Kilpilahti and Porvoo area, and they aim to investigate the impacts of industrial emissions on air quality. In 2014, we renewed the air quality measurement system. The system is more reliable than the previous one and meets the current requirements for the availability of air quality measurement data.

Taking part in developing ways to reduce methane emissions in palm oil production

The production of palm oil, one of the feedstocks of renewable diesel, generates a lot of organic material that decomposes into methane and carbon dioxide over time. In 2014, we took part in development work to promote the adoption of various methods to reduce methane emissions at palm oil mills. Currently, only a fraction of the mills have methane recapture systems.

We do not own any palm oil plantations or mills, but we are actively engaged in distributing know-how through diverse visits and training schemes and by investigating means of funding recovery systems.
