Environmental Sustainability

Our situation as a managed-office tenant

eSolia's Tokyo office is located within Workstyling, a shared office network operated by Mitsui Fudosan. As a tenant in a managed facility, we don't directly control the building's electricity procurement. However, Mitsui Fudosan is a member of RE100 — the global initiative committing to 100% renewable electricity — and has published a group-wide decarbonization plan that includes greening common-area power across its portfolio. Our building's environmental performance is in capable hands, even if not under our direct management.

What we can influence is where our work actually runs — and for a company like eSolia, that means the cloud.

Where our real footprint lives

Professional services firms aren't factories. We don't operate kilowatts of manufacturing equipment. Our meaningful energy consumption happens in data centers and global cloud networks — not in our office's light switches. Our servers are our smokestacks, and they belong to someone else's infrastructure.

That makes the environmental commitments of our infrastructure partners directly relevant to our own footprint.

Our infrastructure and their commitments

Microsoft 365 and Azure

Our primary productivity suite — email, documents, collaboration, Teams — runs on Microsoft 365. Several internal applications run on Microsoft Azure. Microsoft has committed to matching 100% of its electricity consumption with renewable energy purchases, and has set a goal to be carbon negative by 2030. Their sustainability reports are publicly available and independently verified.

Cloudflare

We use Cloudflare for DNS management, website delivery, security, and Zero Trust network access. Cloudflare has committed to powering its global network with 100% renewable energy and has pledged to remove all historical carbon emissions going back to its 2010 founding.

AWS (Amazon Web Services)

Several of our web properties and services run on AWS infrastructure. Amazon has publicly reported reaching 100% renewable energy matching for AWS globally.

Netlify and Deno Deploy

Some of our sites are hosted on Netlify and Deno Deploy. Netlify runs on AWS infrastructure, inheriting its renewable commitments. Deno Deploy distributes workloads across multiple cloud providers with an emphasis on edge efficiency.

Salesforce (Slack)

We use Slack for internal team communication. Slack is owned by Salesforce, which has published net-zero commitments and renewable energy matching as part of its corporate sustainability program.

eSolia PROdb — ColoHouse, Chicago

Our proprietary database platform, eSolia PROdb, runs on dedicated infrastructure at a data center in Chicago, Illinois, operated by ColoHouse. This Tier III facility meets rigorous uptime and security standards. We don't currently have public renewable energy disclosures from this provider, and we note that honestly here.

A personal note

Our founder has solar panels installed at home, generating clean electricity for his household. He and his wife, along with their independent children, also maintain composters to reduce kitchen waste going to landfill. It's a small thing in the grand scheme, but it reflects a personal commitment that carries into how we think about eSolia's operations.

Japan deserves mention here too. Mandatory, granular waste separation for recycling is a fact of daily life across the country — a cultural baseline of environmental awareness that residents simply live with. It's not a special initiative; it's just Tuesday. That mindset shapes how we approach responsible operation.

What we're working toward

We are a small firm. Grand pledges without substance behind them would ring hollow. Our realistic near-term focus:

• Continuing to favor cloud providers with strong, verified renewable energy commitments when we have a choice
• Monitoring our key infrastructure providers — especially those without current public disclosures — for updated commitments
• Publishing this page and keeping it current, so clients and partners can make informed assessments of our supply chain stance
• Exploring whether Non-Fossil Certificates (非化石証書) or equivalent instruments would be applicable and meaningful for our specific operational profile
