Greenhouse gas emissions
We aim to be net zero on emissions generated by our operations by 2050 or sooner, in step with society, as well as on emissions associated with the energy we need to power them.
In October 2021, we announced an absolute emissions reduction target of 50% by 2030, compared with 2016 levels on a net basis. This new target covers all Scope 1 and 2 emissions under Shell’s operational control and complements our existing carbon-intensity targets.
Greenhouse gas emissions performance
Shell reduced Scope 1 and 2 emissions under its operational control from 83 million tonnes in 2016 to 68 million tonnes by the end of 2021 (see Delivering our Climate targets).
This decrease was in part driven by the shutdown of the Shell Convent Refinery (USA) in late 2020, lower production at the Shell Norco Manufacturing Complex (USA) due to Hurricane Ida, and divestments in 2020 and 2021, which included the Martinez and Puget Sound refineries in the USA and the Fredericia refinery in Denmark. These decreases were partly offset by higher emissions due to the restart of the Prelude floating liquefied natural gas (LNG) facility in Australia (which was shut down for most of 2020) and increased flaring at Shell Nigeria Exploration and Production Company Limited (SNEPCo) in Nigeria.
In 2021, we implemented a variety of measures to reduce the energy use and increase the energy efficiency of our operations. Examples of some of the principal measures taken in 2021 are listed in the 2021 Annual Report.
Our indirect greenhouse gas emissions associated with imported energy (Scope 2) were 8 million tonnes in 2021 (using the market-based method), compared with 8 million tonnes in 2020.
We undertake external verification of our greenhouse gas emissions annually. Our 2021 Scope 1 and 2 greenhouse gas emissions have been verified to a level of limited assurance. Limited assurance means nothing has come to the verifier’s attention that would indicate that the greenhouse gas data and information as presented in the Greenhouse Gas Statement were not materially correct.
