London's Tube Goes Net-Zero by 2030

Discover how London is on track to become one of the world’s greenest cities by achieving a net-zero carbon goal by 2030. Dive into Mayor Sadiq Khan’s plan to power the iconic London Underground with renewable energy and its implications for a greener future.

In the grand tapestry of cities worldwide, London is weaving a unique thread—the thread of sustainability. The vision? To become a ‘net-zero’ carbon city by 2030, a feat that would position London among the greenest metropolises globally. Mayor Sadiq Khan is at the helm of this transformative journey, and one of the most significant steps towards this ambitious goal is powering the iconic London Underground with renewable energy. Let’s delve into the details.

Paving the Way for Renewable Transportation

Sadiq Khan’s Green Vision

Sadiq Khan, the Mayor of London, has set an audacious goal: to transition the London Underground, affectionately known as the Tube, to run entirely on renewable energy by 2030.

The Power Purchase Agreement (PPA)

In February of this year, Transport for London (TfL) relaunched its Power Purchase Agreement (PPA) tender to achieve this milestone. But what exactly is a PPA? It’s an agreement to ensure that 10 per cent of TfL’s energy comes from renewable sources. The contract for this tender is anticipated to be inked in early 2024, marking the first significant stride towards making the Tube carbon-neutral.

The Underground’s Current Energy Landscape

Currently, the London Underground falls short of the UK average for renewable energy utilization. Only a fraction of its power is from wind, solar, bioenergy, or hydroelectric sources.

A Lofty Ambition

Helena Bennett, Head of Climate Policy at the think tank Green Alliance, acknowledges that the current usage of renewable energy on the Tube is modest. However, she applauds Mayor Khan’s lofty vision.

The Path to 100 Percent

Bennett notes, “The growth from 10 per cent in 2024 to 100 per cent in 2030 is quite ambitious.” She highlights that a more significant portion of the wider UK grid already relies on electrification compared to the London Underground.

Challenges on the Green Track

Power purchase agreements can be complex and competitive, contributing to the gradual pace of progress. Nevertheless, the real focus should be on the ambition to scale rapidly over the next five years—a pivotal aspect of this green revolution.

London's Tube Goes Net-Zero by 2030


London’s journey towards becoming a ‘net-zero’ carbon city is marked by visionary leadership and bold initiatives. Mayor Sadiq Khan’s commitment to powering the London Underground with renewable energy by 2030 is a significant stride in this direction. While challenges exist, the ambition to rapidly scale up renewable energy usage over the next five years is the true north of this green revolution.

The future of London is not just brighter; it’s greener. As the city’s iconic Tube transforms into an eco-friendly marvel, it sets an example for urban centres worldwide, showing that sustainable transportation is not a distant dream but an achievable reality.
