CarbonProxy

The software provides a clear CO2 report based on your uploaded bills. It uses versioned emission factors which adds credibility. The proof feature links numbers back to specific documents, which is useful for audits.

The tool is good, but the free plan only allows thirty documents. Make sure you read the terms carefully before you start uploading your bills.

This software is absolutely brilliant for anyone who needs to answer carbon questionnaires from big customers. The ability to drag and drop all my bills and get a ready-to-paste report is a huge time saver. I love that the proof is built right in, so I can show exactly where every number came from. It takes the stress out of compliance. The free plan is a great way to start without any risk.

I have been drowning in supplier questionnaires for ages, and every time I thought about hiring a consultant, I would lose my mind over the cost. CarbonProxy has completely changed that dynamic for me. The way it takes those messy electricity and fuel bills and turns them into a clear, proof-backed report is genuinely magical. I love that it uses a plain calculator for the math, so I know the numbers are not just some black-box AI guess. Being able to click on any figure and see the exact page from my bill gives me total confidence when I send these to my clients. It feels transparent and honest. The interface is simple enough that I did not need to read a manual. I can just upload the files and get my answers. It is refreshing to see a tool that actually solves the problem of proof without making you feel like you are losing your mind over spreadsheets. I am thrilled to have this in my workflow.

The interface looks clean and the AI reading of bills is impressive. However, the free tier limits you to thirty documents. For a small business just starting, this cap feels restrictive. It works well, but you will need to upgrade sooner rather than later to handle ongoing reporting needs.
