Bolser agency measures its greenhouse gas emissions annually across Scopes 1,2, and 3 and has them independently reviewed by Green Gain Ltd against the GHG Protocol. 

Every website, app and digital platform has a carbon cost. Ours is measured annually, independently reviewed and reported in full. The work we do to bring it down makes the digital estates we build for clients faster, leaner and cheaper to run.

What this means for you

Sustainability baked into our software engineering process.

Most of the digital products we build run on cloud infrastructure, which consumes more power than anything else we produce. Through ongoing management and usage optimisation, we reduce the data a platform moves, the processing it demands and the infrastructure it sits on. Less energy used and better performance delivered.

When we cut the carbon intensity of a client platform through closer management, three things happen: the site gets quicker, the hosting bill gets smaller, and the emissions attributable to that platform fall (Scope 3 reporting).
 

How we reduce the carbon cost of your digital estate
 

• Performance-led development. We build to move less data and reduce processing. Fewer requests, lighter payloads, better caching. Users get a faster experience, and the infrastructure does less work.
• UX reviews to remove waste. We regularly review journeys to strip out unnecessary clicks and page loads. Every page a user does not need to load adds needlessly to the  carbon footprint of your website.
• Fit for purpose hosting. Environments are reviewed and optimised to avoid over-provisioning, with auto scaling implemented so capacity follows demand rather than sitting idle.
• Enhanced traffic management. Smarter routing and delivery cut unnecessary transfers.
• Digital housekeeping. We delete redundant historic files and videos across the CMS platforms we manage on our clients' behalf, and across our own cloud storage. Platforms that are no longer required are shut down rather than left running and consuming energy.
• Regular refactoring. Code is revisited on an ongoing basis, not left to build up inefficiency.
   

Our reporting process:
 

Measured properly. Reviewed independently. Never self-certified.
 
Our greenhouse gas inventory is prepared in line with the GHG Protocol Corporate Accounting and Reporting Standard:
 

• Corporate Value Chain (Scope 3) Standard
• UK Government DESNZ 2025 conversion factors
• EcoInvent v3.11
• Supplier-specific CO₂e intensities for cloud services
   

Our output data is then submitted to Green Gain Ltd, an independent environmental consultancy, for critical review. Green Gain assess whether our methods are scientifically and technically valid, whether our data is appropriate, and whether our reporting is transparent and consistent. 

Bolser’s most recent inventory covers the reporting period 1 December 2024 to 30 November 2025 and was reviewed by Green Gain Ltd on 4th June 2026. The review was carried out by Ashley Robb, Director of Green Gain Ltd. 
 

Our reporting overview:
 

• Scope 1
  The direct emissions from our own operations
• Scope 2
  Purchased electricity, reported on both a location-based and market-based basis
• Scope 3
  Our value chain, including purchased goods and services, cloud hosting, waste, business travel and employee commuting
   

Our assessments and calculations are in line with the requirements of the GHG Protocol and UK Government reporting guidelines. We use good quality GHG conversion factor datasets from a reliable independent source, and present the information in a clear, relevant and consistent manner.

As a Microsoft supplier, Bolser reports a service-level account of emissions attributable to the work delivered, allocated on turnover share and stated against a defined reference unit.
 

Results:

We measure annually and our emissions continue to fall as we work towards net zero. Our most recent reduction figures were:
 

The Bolser net zero pledge:
 

Bolser has committed to net zero by 2050, with a minimum 50% reduction by 2034 and an interim 25% reduction by 2030, against a 2019 baseline:
 

• An interim 25% reduction by 2030
• A minimum 50% reduction in emissions by 2034
• Net zero by 2050 at the latest
   

Our operations:

Reducing our carbon footprint is the single biggest environmental difference we can make as a business:

• Improved measurement of utilities. Working from data rather than estimates
• Green energy tariffs, and reduced gas and electricity consumption
• Employee engagement and training - impact happens when everyone understands how they can contribute
• Sustainable travel with video conferencing used wherever practical
• Sustainable procurement across our supply chain
• Offsetting what remains. Bolser offsets 200 tonnes CO₂e annually through tree planting with Make It Wild in Nidderdale, North Yorkshire, covering both company operations and employees' personal footprints.
