Ill thought out regulations can make things worse - I am convinced this is the case for the UK's Online Safety Act, for example. That (and the proposed ban on social media for under 16s) is also promoted on "we must do something" grounds.
I am very much in favour of some proposed changes under the law - e.g. improving repairability and reusability of some product categories.
I have doubts that some discouragement of destruction of new products fixes the big underlying problem with clothing: the production of cheap junk not designed to last. Under these regulations (at least as summarised in the article), they offer it to charity, charity rejects it, then they are free to destroy it.
2. do a bunch of studies to validate it
3. go through a pretty complicated, comprehensive, pretty long review process to debate and make it work within the existing regulatory system
4. eventually implement it
5. measure its impact
6. adapt or revoke according to the results
We are at the 4th step. Why would you assume your concerns haven’t been already taken in account in all the previous steps? It’s all public, you can look for the reasoning and justification
