Obct how can making anything better for the environment be insignificant?
Cars have laws to lower emissions...and yes this could go on and on....
anything being done for a cleaner planet will never be insignificant in my eyes
I'll start at the end, consumption is the problem, we need to consume less than this planet is able to provide, and that's not likely to happen, regardless of the amount of sustainable practices we employ. In some ways, we make it worse because big business have discovered how lucrative sustainability is, and here's the good bit for business, governments all around the world legislate to ensure sustainable practices, which encourage destruction of the old and replacement with the new.
I could use buildings as an example, but I'll go with cars, I once had all these exact figures down on paper but now I must try to get close to them from memory:
The carbon contained within a new car is the sum total all the carbon required to manufacture it, this includes such minor items as the fuel that the miner used the morning he went to work in the Pilbura to dig up the iron ore that was shipped to china to make the steel that was shipped to Japan to make the car that was shipped back to Australia to be taken to the dealership for us to buy.
I've seen estimates that a car needs to be on the road for up to 25 years for there to be a net benefit to the environment, as opposed to recycling it after 10 years and putting all that carbon back into its successor. Hands up those of us that drive a car that's 25 years old? my hands remain in my keyboard.

we know in the case of cars, it does not, unless we a) keep the car for many years & b) use it infrequently and rely heavily on public transport.
So for me, a really eco friendly surfboard does not relate so much to the materials or manufacturing but more to the amount of time you keep it and how you dispose of it.
Here's one more fun fact about modern cars that's quite interesting in terms of how legislated sustainability has helped the car industry make more money.
40 years ago, the national average for fuel consumption was around 11.7 L/100 klms (it may have been more, it may have been less I can't remember what the exact number was because only the next statistic is the important one).
We then had 40 years of astounding automotive developments in terms of engine management, design emissions control and manufacture that has allows us to arrive at a new national average. 11.7 L/100 klms.
That's right, same number, that's why me not remembering the exact number is not important.
Why?
Because for any given engine capacity, the overall weight of a vehicle has increased due to legislated change relating to required safety items and a more robust body construction.
it's a win win for the car companies, law makers say old cars must come off the road because they energy inefficient and unsafe, new ones are made, more and more carbon is embodied into them, the planet suffer
That's why I gave up on environmentalism some years ago and began to think more like a neo Malthusian
