Road to COP 26: re­ima­gin­ing en­ergy: just trans­ition
As we ap­proach COP 26, there is ex­tens­ive dis­cus­sion of the shift to net zero and how it will be achieved; a large part of this will be the trans­ition from re­li­ance on fossil fuels to a more en­vir­on­ment­ally...

En­ergy Trans­ition: The evolving role of oil & gas com­pan­ies in a net-zero...
After an ex­traordin­ary year of health and eco­nom­ic chal­lenges, the glob­al oil and gas sec­tor has an es­sen­tial role to play in the eco­nom­ic re­cov­ery. The same could how­ever be said of any eco­nom­ic re­cov­ery and ex­pan­sion over the past 100 years – dur­ing this time oil and gas com­pan­ies have provided most of the primary en­ergy that has fuelled huge eco­nom­ic growth. But this time does look dif­fer­ent. The oil and gas sec­tor will power eco­nom­ic re­cov­ery not just through oil and gas ex­plor­a­tion and pro­duc­tion, but also (and per­haps counter-in­tu­it­ively to some) through fa­cil­it­at­ing the trans­ition to a lower-car­bon eco­nomy and even­tu­ally a net zero fu­ture. This re­port presents a wide-ran­ging re­view of the role of oil and gas com­pan­ies in that fu­ture.
