In addition, this form of CCS is relatively simple and low-cost, given that it involves a fairly pure stream of C02 that needs to be separated from the extracted natural gas during extraction and processing in any case, and storage is readily available close to the production sites in most cases. We thus additionally include all countries in the Middle East with significant oil- and gas-related vented C02 emissions,28 as well as China, India, Indonesia, Malaysia, Brunei, and Argentina. As reported, these amounted to only 7.0 MtC02 in 2013 (6.9 MtC02 when excluding Norway).
