Westminster's Role in the Global Energy Industry
London has been a hub for the oil and gas industry for more than a century, and Westminster is home to some of the sector's most influential offices. The proximity of government, regulators, diplomatic missions and financial institutions makes the borough a natural base for companies that operate across continents and need to engage with policymakers and investors.
Today the industry faces a period of profound change. Oil and gas companies are under pressure to reduce emissions, invest in lower-carbon technologies and adapt to evolving energy policy, while still supplying the energy that the economy relies on. Many are expanding into renewables, hydrogen, carbon capture and electric vehicle charging.
