OUR APPROACH
Beyond connected mobility.
Towards a sustainable everyday.
We look at rail communications, traffic safety, AI and digital twins through the lenses of environment, people and trust. From product functions to operation and maintenance, connected decisions support better mobility.
DIRECTION
From the first design decision
to the end of a service life.
ESG offers a way to examine design, implementation and operation together. The responsibilities around a technology depend on its setting, users and data boundaries. Six working themes explain CREWAVE’s public ESG direction.
Mobility for people
Respect · Accessibility · Site safety
Collaboration that builds trust
Fair relationships · Information · Clear responsibility
CONDUCT STANDARDS
Standards, checks and actions
Each item identifies the standard, what to check and the action when an issue is found. Implementation and its scope are reported separately with verified evidence.
Purpose and impact of technology
StandardDefine the problem, users and affected workers before proposal or design. Feature count or publicity alone is not a reason to deploy.
CheckInclude safety, accessibility, operating effort and potential adverse effects in requirements, linked to customer and operator feedback.
ActionRemove or revise functions that do not serve the purpose. Record decisions and remaining risks in handover information.
Environmental criteria across the life cycle
StandardAssess electricity, materials and replacement scope across design, procurement, installation, maintenance and disposal.
CheckCompare power assumptions, repairable components, support conditions and disposal requirements on equivalent boundaries.
ActionChoose ways to avoid unnecessary replacement and resource use among options meeting quality and safety requirements, and retain the comparison.
Safety and rights of users and workers
StandardDo not disregard one group’s safety or rights for the convenience of pedestrians, drivers, operators or maintainers in another group.
CheckIdentify risks, access restrictions, information needs and workload by scenario and include them in design and site reviews.
ActionDocument competing requirements and alternatives for an authorised decision. Disclose unresolved limitations to the customer.
Public statements supported by evidence
StandardDistinguish plans, tests, contract awards, delivery and operation. Do not generalise a product or site result to the whole company.
CheckFor each metric, certificate or example, check the entity, scope, period, conditions and original evidence, together with disclosure permission.
ActionCorrect or withhold unsupported or overstated claims. Retain the original and reasons for correction so earlier statements remain traceable.
Responsibilities and approval in collaboration
StandardDefine responsibility and decision authority across design, supply, installation, testing and maintenance according to the contract and scope.
CheckConfirm interfaces, deliverables, acceptance criteria, change approvers and contacts before work starts.
ActionResolve gaps or conflicting requirements with the relevant parties before implementation. Record verbal changes with their date and confirming parties.
Controls for data and AI use
StandardUse data only for an authorised purpose and within permissions. Do not automatically finalise significant safety or personnel decisions from AI output alone.
CheckCheck collection grounds, sources, authorised access, retention and the model’s conditions and error risks.
ActionRestrict inappropriate use or erroneous outputs for review. Carry out necessary correction, deletion and communication.
Ownership, execution and improvement records
StandardDistinguish standards from responsibility for carrying them out, and do not report plans as completed results.
CheckLink roles, work scope, review date, findings, action owners and supporting records.
ActionDefine causes, actions and completion checks for omissions or recurring problems. A commitment or training plan alone does not prove completion.
ESG responses and submission history
StandardBase assessment responses on the actual question and facts and evidence available at submission. Do not infer earlier answers from a score.
CheckLink each answer to evidence files and versions, applicability period, submission date and receipt. Explain non-applicability.
ActionPreserve the original when correcting an error and record the basis and changes. Do not mark an unavailable submission as verified.
IN PRACTICE
Connect the principles
to a working process.
Specific considerations depend on the site and contract.
- 01
Define
Problem, users and scope
- 02
Design
Functions, environment, safety and security
- 03
Implement & verify
Site conditions, tests and changes
- 04

Monitoring, service, replacement and records
Questions for review
- Are the problem and intended users clearly defined?
- Are technical performance and social or environmental effects distinguished?
- Is there information for operation and maintenance as well as installation?
A PRACTICAL EXAMPLE
When considering an intersection improvement
Waiting time alone cannot describe an intersection. A review can also consider pedestrian crossings, emergency vehicles, general traffic and operating conditions. Digital-twin scenarios can support that review; simulated comparisons are not measured environmental improvements.
Illustrative example for reviewWORKING PRINCIPLES
Scope and working process
These are public conduct and review principles for work. Roles describe functions to designate for a task, not established departments or named appointments. Implementation and results require approved policies and records for the relevant period.
Scope
Review environmental, people and integrity impacts across planning, engineering, procurement, manufacture, testing, installation and maintenance. Apply customer requirements within their contractual, site and product boundaries.
Responsibilities
The task owner identifies risks and evidence; the supervisory role reviews priorities, resources and remaining risk. Separate preparation from evidence review and record the publication approval route.
Conduct
Distinguish verified facts, plans and public principles. Do not extend another company’s requirements or a site-specific certification into company-wide results, or claim unsupported figures or assessment outcomes.
Workflow
List requirements, assess scope and risk, define responsibility and completion criteria, verify evidence, then review disclosure boundaries. Reassess changes in design, purchasing and working conditions.
Review and records
Link each requirement to its source/version, review date, scope, owner, open issues and follow-up. Preserve actual submitted ESG questions, answers and attachments separately from later improvements.
Concerns and improvement
Check source evidence and correction history when public information is inaccurate. For rights or integrity concerns, first check the ESG concern page for intake availability and a dedicated route rather than sending sensitive details to sales.
