Around Earth Day 2026 (22 April), more than 1,400 companies publicly shared sustainability activity.

The number of companies regularly discussing sustainability initiatives in the UK is now above 15,000 - and growing every month.

This isn’t just awareness. It’s a real-time view of how companies are thinking about sustainability, where they’re investing, and how priorities are shifting.

And that’s where it becomes useful.

Sustainability is now a live signal

Sustainability used to sit in annual reports.

Now it shows up in real time - through:

• Social posts
• Employee initiatives
• Partnerships and programmes
• Procurement processes

When companies talk about it, it often reflects internal focus, investment and change.

Not every post leads to a supplier review. But it shapes priorities, influences decisions, and signals where attention is going.

What we saw last week

A few examples from the 1,400+ companies:

The Access Group

• Ran a global hackathon tackling energy, waste and carbon challenges
• Winning team built a tool to make AI prompts more energy-efficient
• Backed by employee initiatives focused on everyday sustainability

Nestlé

• Highlighted regenerative agriculture and sustainable dairy
• Showcased partnerships helping farmers reduce impact and improve output

Kerv Group

• Cut Scope 1 & 2 emissions by 42%
• Moved offices to renewable energy
• Ran climate workshops and employee pledges

Just Eat

• Teams carried out plastic clean-up initiatives in multiple cities
• Linked activity to long-term net zero and operational goals

Smith & Nephew

• 95% of manufacturing waste kept out of landfill
• ~60% zero carbon energy usage
• Employee-led recycling drives and clean-ups

This isn’t a one-off moment

Earth Day creates visibility.

But the activity behind it continues:

• New sustainability initiatives
• Ongoing investment and reporting
• Employee engagement programmes
• Operational changes across the business

And thousands of companies are sharing that activity every week.

Why this matters

This kind of activity tells you:

• What companies care about right now
• Where they’re investing time and budget
• When internal focus is shifting

It doesn’t guarantee action.

But it gives context and timing - which is where most outreach succeeds or fails.

How Honch tracks it

We don’t just flag “sustainable companies”.

We track sustainability as it happens:

• CSR, ESG and environmental activity
• B Corp certifications and charitable initiatives
• Employee-led programmes
• Operational and supply chain changes

Alongside the decision-makers behind it.

So you can see what’s happening, when, and who’s driving it.

The bottom line

Sustainability is no longer background noise.

It’s visible. It’s current. And it’s happening every day.

Last week alone, 1,400 companies showed that.
