A glance through Saudi Aramco’s recent press releases show the powerful state oil company means environmental business.

In July alone it launched SAEV, pledged to plant 1.2 million mangrove trees along the Saudi coast and set aside land for the region’s first eco-park–at Ras Tanura, near its Persian Gulf oil export terminal. In June, the company announced a desert wild-life preserve. In March, it launched an oilfield water recycling program.

In February, Saudi Aramco sponsored the First Saudi Renewable Energy Conference and Exhibition at King Fahd University of Petroleum and Minerals, heralded as “a platform for a new start-up in the concept of renewable technology.”

“Not only does the company hope to utilize the best technologies to bolster its status as a key global competitor, but it intends to develop and produce such technologies as well,” said public affairs manager Nasser al-Nafisee.

This could all be green wash, but consider that the biggest buyers of Saudi crude are Asian countries which are not always squeamish about the environment.
