What our clients say

Don't just take our word for it...

"As a recently certified B Corp, finding a way to measure and reduce our carbon emissions as a business was a massive priority but we weren't really sure where to start. Seedling have been fantastic from the start at guiding us through the process, taking the time to explain and helping us improve our own knowledge, and their software has made everything a breeze! With an incredibly quick turn-around time, we have now received our insights and are looking forward to implementing the actions and targets that the team help us set in order to reduce our emissions and sharing that with our community through the integrated engagement functionality. I highly recommend Seedling and their great team, it was a pleasure to work with them and we look forward to doing so again."

"I have found Seedling to be a relatively easy and hassle-free method of carbon tracking. Their web app combines sleek design with AI features, making carbon reporting easy. My favourite feature so far is the AI that matches categories to the expenditure entered. This saves lots of time and is really accurate. The team (Henry) has also been really helpful, providing individualised support where needed."

"Seedling helped us build a clear Carbon Reduction Plan so we can make meaningful reductions and align ourselves with NHS Net Zero goals. We now have a much clearer understanding of our carbon footprint and where the biggest drivers of emissions sit. This will enable us to make more informed decisions and stronger conversations with partners/suppliers."

Seedling gave us the foundations to track our impact at a product level, meaning we can build tracking out for every product sold and very quickly build a plan. For the first time, we have a really clear picture of our controllable operation and product impact, and can build structures to communicate effectively with customers.

FAQs

Your questions answered

What is Scope 3 and why does it matter?

Scope 3 covers all indirect emissions in your value chain - from the goods and services you buy, to business travel, employee commuting, and what happens to your products at end of life. For most businesses, Scope 3 accounts for more than 70% of total emissions, so any credible Net Zero strategy has to include it.

Which Scope 3 categories do I need to measure?

The GHG Protocol defines 15 Scope 3 categories, split between upstream (e.g. purchased goods, business travel, waste) and downstream (e.g. use of sold products, investments). Not all will be material to your business. Seedling's assessment helps you identify which categories matter most and focuses your effort accordingly.

What data do I need to measure Scope 3?

It varies by category, but typically includes supplier spend data, business travel records, freight volumes, and employee commuting information. Your Seedling adviser will tell you exactly what to collect based on your business, and will help you use approved estimates where primary data isn't available.

What if my suppliers don't share emissions data?

This is common. Where supplier-specific data isn't available, Seedling uses spend-based or industry-average emission factors drawn from recognised databases. We also provide supplier engagement templates to help you start collecting primary data over time.
