Scope 1
Direct emissions
Small direct sources under BUSUP's own control, including equipment, minor combustion sources and the limited vehicle fleet directly held by BUSUP.

Climate & Emissions Policy
How BUSUP measures, manages and works to reduce greenhouse gas emissions across its operations, value chain and mobility network.
Effective from 2026 Global scope
01 Measure
02 Reduce
03 Engage
Policy objective
BUSUP's climate approach is built around understanding where emissions arise, reducing them at the source and progressively extending consistent measurement and reduction practices across every market in which we operate.
01
Why this policy exists
Purpose
Climate change is one of the defining risks facing urban mobility, and BUSUP, as a company that exists to move people more efficiently, has a direct stake in reducing the emissions associated with how that movement happens.
This policy sets out how BUSUP measures, manages and works to reduce its greenhouse gas (GHG) emissions, and how it engages the partners and employees whose decisions shape that footprint.
It sits alongside BUSUP's Residue Policy as part of the same environmental management approach: one policy addresses what the company discards, while this policy addresses what it emits.
02
Applicability
Scope of Application
This policy applies to BUSUP as a whole — every entity, office and employee, across every country where BUSUP operates its shared mobility platform.
It covers emissions generated directly by the company, emissions associated with the energy it purchases, and emissions arising from its wider value chain, including the transport services it contracts to deliver its platform to clients.
Global measurement
One policy. Progressively consistent data.
BUSUP's ability to quantify emissions in comparable detail is not yet identical across every market. Spain, where the company reports annually to the national environmental authority, currently has the most complete and formally verified dataset.
As reporting matures, the same rigor is being extended progressively to every country of operation.
03
Our footprint
How BUSUP's Emissions Arise
BUSUP does not own or operate the vehicles that carry passengers on its network. The fleet used to deliver the service is predominantly provided by subcontracted transport operators.
This structural feature of the business model shapes how the company's carbon footprint is distributed under the categories established by the GHG Protocol Corporate Standard.
Scope 2
Purchased energy
Electricity purchased to run BUSUP offices and the technology infrastructure supporting its mobility service.
Scope 3
Value chain
The majority of BUSUP's footprint sits here: principally fuel burned by subcontracted vehicles, together with employee commuting and business travel.
Largest share Why Scope 3 matters
Because most of the fleet is subcontracted, BUSUP's direct operational emissions appear relatively modest. The emissions associated with delivering the service are not. This is why partner engagement and target setting place particular emphasis on Scope 3.
04
Climate commitment
Reduction Commitments & Target Setting
SME Climate Hub Active commitment
Building a structured emissions-reduction pathway.
BUSUP has joined the SME Climate Hub as the formal starting point for structuring its emissions reduction pathway rather than treating target-setting as an afterthought.
From this base, the Sustainability and Innovation function is responsible for translating that commitment into concrete, time-bound reduction targets covering Scope 1, Scope 2 and the material Scope 3 categories identified by BUSUP.
Progress is reviewed at least once a year.
05
Value-chain action
Engaging Our Transport Partners
Because the fleet is subcontracted, the single largest lever BUSUP has for reducing its footprint is not in its offices but in how it selects and works with the operators that run its network.
Sustainability criteria are therefore incorporated into how transport partners are evaluated and contracted, alongside the ESG clauses already included in BUSUP's supplier agreements.
01 Fuel efficiency
02 Vehicle age & technology
03 Lower-emission transition
04 Activity & fuel data
Where operators can provide activity or fuel data, BUSUP incorporates that information into its emissions accounting rather than relying solely on estimated factors.
06
Beyond reduction
Carbon Compensation
Reduction first.
Compensation alongside it.
Compensation alongside it.
Alongside reduction, BUSUP supports carbon compensation initiatives, including reforestation and forest conservation projects, as a way of addressing the portion of its footprint that cannot yet be eliminated.
Compensation is explicitly treated as a complement to reducing emissions at the source, not as a substitute for avoiding emissions that can still be reduced.
BUSUP is also exploring partnerships with reforestation organizations capable of helping neutralize residual emissions associated with specific mobility services.
07
Governance
Roles & Responsibilities
Management
Sets the direction for the policy, ensures appropriate resources and visibility, and is accountable for BUSUP's overall climate performance.
Sustainability & Innovation
Owns the measurement methodology, coordinates target-setting and supplier engagement, prepares climate disclosures and reviews this policy annually.
All Employees
Apply the spirit of the policy in day-to-day decisions, from business travel to office energy use, and raise relevant concerns or ideas through available channels.
08
Transparency
Measurement, Reporting & Review
BUSUP measures its emissions annually following the GHG Protocol and discloses the results through its Sustainability Report and other public channels.
This allows clients, partners and the public to track progress over time rather than relying solely on commitments.
The policy is reviewed at least once a year and updated as BUSUP enters new markets, measurement coverage improves or regulation evolves.

Related Policies
BUSUP environmental management
Climate & Emissions Policy + Residue Policy
This policy is designed to work alongside BUSUP's Residue Policy, which governs how the company manages waste arising from its operations.
Together, the two policies form the environmental core of BUSUP's broader sustainability approach.
Environmental concerns relating to either policy can be raised through the confidential reporting channel available to employees, partners and contractors.
BUSUP
Measure what matters. Reduce what we can. Improve what comes next.
Our climate approach evolves alongside our operations, our data and the transition of the transport ecosystem we work with.
