Are there any 'green design' firms or corporations?

I think that was very much my point, these things happen at a corporate level when it aligns with a companies goals and initiatives. But that doesn’t mean theres a slew of “Green consultancies” like you see in architecture. There are a few more regulatory focused agencies that can come in, look at a product and grade it based on it’s sustainability.

There are plenty of companies that focus on eco focused products - just walk around a Whole Foods. Furniture, health and beauty, anything related to food have already gone through their “green” revolution - but same mantra, designers at those companies or founders of new companies forged it into their plans. “I can sell a BPA free bottle for 45% more than a regular one because parents see this value” or “I’m going to start a company that only makes hemp cloth outdoor goods”.

I guess the cliffnotes is “you can usually apply this thinking at most jobs” you just need to make sure it aligns with the company goals, ROI or product lineup.
