Reporting on what your company actually does — accurately and without overstating it.
Practical support for companies asked by customers or partners to report on environmental and social matters — finding the right framework, gathering the data, and producing a first report that reflects what the evidence supports.
What this engagement produces
At the end of six weeks, your company will have a first sustainability report drafted in collaboration with your team — grounded in measured figures, with estimates clearly identified as such, and a data collection process your internal team can maintain independently going forward.
The work covers which reporting frameworks apply at your company's size and in response to the request you have received, what data needs to be gathered and from where, and how to present that data in a way that is accurate — neither understating what you have done nor claiming more than the evidence supports. The distinction between measured figures and estimates is maintained throughout and stated clearly in the report.
Right framework
Which frameworks are relevant to your company's size and the request you have received — without adopting more than is warranted or useful.
Data collection process
A process your internal team can follow to gather and maintain the data needed for future reporting — not dependent on external support each year.
A first report
A report drafted with your team — not for them, but with them — so the people who will maintain reporting in future understand what went into it.
Honest separation
Measured figures and estimates are kept clearly distinct. Readers can see what was directly measured and what was calculated or estimated.
The situation many companies find themselves in
Companies in Japan are increasingly receiving requests from customers, partners or supply chain partners to provide information on their environmental and social practices. These requests arrive in different forms — a questionnaire, a framework name, a set of data fields — and often with a deadline that does not leave much time to work out what is actually being asked.
The difficulty is not usually that the company has nothing to report. Most companies already do things that are worth describing — energy management, waste practices, supply chain policies. The difficulty is knowing which frameworks apply, what data must be gathered to satisfy them, and how to present what the company does accurately — without accidentally claiming more than the evidence supports, which creates a different kind of problem.
There is also a practical question of what happens next year. A sustainability report produced under time pressure, with data assembled ad hoc, leaves the company having to rebuild the same process again when the next request arrives. This engagement is designed to produce a first report and a data collection process — so that subsequent reporting can be done internally, without starting from the beginning each time.
The typical situation
A company asked by a customer or partner to report on environmental and social matters — with limited time and no established process for doing so.
What makes it hard
Framework choices, data gaps, and the risk of overstating — reporting accurately requires more than good intentions; it requires a structured process.
What this addresses
Six weeks to establish the right framework, gather the data, produce a first report, and put in place the process your team needs for future reporting.
The approach taken in this engagement
The engagement begins by identifying which reporting frameworks are relevant. This is not a theoretical exercise — the frameworks applicable to a company depend on its size, its sector, and the nature of the request it has received. Applying a framework designed for a multinational to a mid-sized company produces a report that is impractical to produce and not what the request actually required.
From there, the work turns to data: what must be gathered, from where within the company, and what can be measured directly versus what will need to be estimated. The data collection process is designed with your internal team so that the same process can be followed in future reporting periods without external support.
The first report is drafted in working sessions with your team — not handed over as a finished document produced elsewhere. The goal is a report your people understand and can stand behind, with measured figures and estimates clearly distinguished throughout.
What makes this approach sound
Framework selection is matched to your company's actual situation — size, sector and the specific request received — rather than defaulting to the most comprehensive option.
The data collection process is designed to be maintained internally. The engagement closes with your team able to gather what they need in subsequent years without starting from scratch.
The report is drafted with your team — involving the people who know where the data comes from and what it represents, not assembled at a distance from them.
Measured figures and estimates are clearly separated in the report — a distinction that protects your company from claims of overstating and is expected by informed readers.
How the six weeks are structured
Framework and scope
Identifying which frameworks apply and what they require — matched to your company's size and the specific request received. Scope of the first report agreed.
Data gathering and process
Working with your team to identify data sources and gather figures. The data collection process is documented so it can be repeated independently in future periods.
Report drafting and handover
The first report is drafted in working sessions with your team. Measured figures and estimates are clearly distinguished. Both the report and the data process are handed over at close.
On accuracy and what it protects
The emphasis on distinguishing measured figures from estimates is not a formality. Companies that cannot clearly identify which figures are directly measured and which are calculated or assumed are in a weak position if questioned by auditors, customers or partners. The report this engagement produces is designed to be defensible — which tends to make it more useful, not less.
The engagement fee
Fee
¥36,000 JPY
Agreed in full before work begins. No revision billing within standard scope.
The fee covers six weeks of structured work — working sessions with your team on framework selection, data gathering and report drafting, plus the data collection process documentation and a follow-up review point. Both the first report and the data process are handed to your company at the close.
Payment schedule is confirmed in writing before work begins. The fee is typically spread across the engagement period — the precise arrangement is agreed at the outset.
What is included
Six weeks of working sessions with your team covering framework, data gathering and report drafting
A first report drafted with your team — not for them — with measured figures and estimates clearly distinguished
A documented data collection process your internal team can maintain independently in future reporting periods
Framework guidance matched to your company's size and the specific request you have received
A follow-up review point after delivery, included at no additional fee
What to expect and how the output holds up
At the close of the engagement, your company will have a report it can submit and a data collection process it can follow independently. The quality of the report can be assessed at close: whether the framework was applied correctly for your company's size, whether measured figures and estimates are clearly distinguished, and whether the report is written in a way that accurately reflects what the evidence supports — no more and no less.
The longer-term value depends on how the data collection process is used. Companies that maintain the process consistently find that subsequent reporting requires significantly less effort, and that the quality of their figures improves over time as the data becomes more systematic.
The horizon table opposite shows what changes at different points after the engagement closes, for companies that go on to use the data process as designed.
Within 3 months
Within a year
Beyond
A submitted first report and a data collection process ready for the next reporting period — managed internally.
Second report produced using the established process. Data quality improving as collection becomes systematic rather than ad hoc.
A sustainable reporting capability — your team can respond to customer and partner requests without rebuilding the process from scratch each time.
Our commitment to you
Accuracy over appearance
The report produced through this engagement will reflect what the evidence supports — not what sounds most favourable. Where data is incomplete or figures are estimates, this will be stated plainly in the report.
Process you can maintain
The data collection process is documented and designed for internal use. The goal is to leave your team capable of maintaining reporting independently — not to create a dependency on external support each year.
No obligation initially
The initial conversation is at no charge and carries no commitment. If what you need is different from what this engagement provides — a more complex framework requirement, for instance — that will be said directly.
