Hi,
As part of our work on supply-chain emissions, we've reviewed the public climate evidence for our main suppliers, including Unilever. The area where we couldn't find much was emissions not falling.
Could you show us how your emissions have changed over the last few years? Anything you can send in the next month would really help.
Thanks,
How these scores work. Every company is scored 0–100 on the same ten published questions, from public evidence only: SINK = (0.3 × sector base + 0.7 × performance) × scale. No company can pay to be scored or to change its score, and any company can challenge its score in public. Full breakdowns and every source: sinkproject.com/company/[name]. Method: sinkproject.com/methodology.
In a real report you also get: every supplier on your own list (including ones not yet on SINK), a view weighted by your spend, an email for each supplier you want to follow up, a spreadsheet with every source, and a re-check in six months.
