Progressing toward net zero with Planet Mark

The Langham Estate is progressing toward net zero, with the support of Planet Mark, taking tangible steps to reduce carbon emissions across Fitzrovia Quarter while preserving its historic buildings and vibrant community. Our journey is about turning ambition into action — from upgrading our buildings to working closely with tenants and suppliers — ensuring a greener, more resilient Fitzrovia for today and the future.

A key milestone in our journey has been measuring our full carbon footprint for the first time. Covering Scopes 1, 2, and 3 across our Head Office and 70 directly managed properties (April 2023–March 2024), this gave us a baseline of 13,324 tCO₂e (market-based).

The data showed that most emissions come from how buildings are used and the materials that go into them, highlighting the importance of collaboration with tenants, suppliers, and project partners.

This approach aligns with the Planet Mark case study, which demonstrates how structured measurement, clear targets, and external verification drive meaningful, credible progress. The Langham Estate has also achieved ‘Net Zero Committed’ certification, recognising that we have measured our emissions, set science-aligned targets, and established a credible transition plan. A short video from the case study brings this journey to life, showing the people, buildings, and practical steps behind our net zero efforts.

1. For our buildings

Directly managed buildings are at the heart of our action. Ongoing refurbishment and upgrades allow us to integrate practical, low-carbon measures:

• 100% renewable electricity for landlord-controlled supplies

• Replacing natural gas boilers with electric alternatives where feasible

• Upgrading to LED lighting

• Improving insulation, HVAC systems, and building fabric

Even small improvements reduce operational emissions while preserving the character and functionality of historic buildings.

2. For our tenants and supply chains

The largest share of our carbon footprint comes from Scope 3 emissions, including leased spaces and materials. Collaboration is key:

• Supporting tenants to reduce energy use within leased spaces

• Delivering building upgrades that enable lower consumption

• Reviewing procurement to align with sustainability objectives

• Engaging suppliers to prioritise emissions reductions and build sustainability capability

By focusing on the areas that contribute most to emissions, we can make targeted, meaningful progress.

3. For our governance and transparency

Sustainability requires strong oversight and regular review. Our Net Zero Transition Plan is updated annually to track progress, test assumptions, and adjust actions. Transparent reporting ensures accountability and complements our ongoing Planet Mark certification.

Our net zero journey has been highlighted in a Planet Mark case study, showing how structured measurement, planning, and action drive meaningful change. A short video from the case study brings this work to life, showcasing the people, buildings, and practical steps behind our progress.

While measuring our footprint and setting targets are important milestones, the real impact comes from continued action, collaboration, and investment. We remain focused on reducing emissions across buildings, supply chains, and leased spaces, ensuring that Fitzrovia Quarter continues to thrive while moving toward a sustainable, resilient future.
