Everyone can do simple things to make a difference, and every little bit really does count.
Stella McCartney
The way my parents brought me up to see the world is still absolutely key to what I am about. The beliefs I was raised with - to respect animals and to be aware of nature, to understand that we share this planet with other creatures - have had a huge impact on me.
I am a fashion designer. I'm not an environmentalist. When I get up in the morning, number one I'm a mother and a wife, and number two I design clothes. So the main thing I need to do is create, hopefully, exquisitely beautiful, desirable objects for my customer.
I ride my bike, I work out, I do a bit of, er, dancey things.
My job is to make desirable, luxurious, beautiful clothing and accessories women want to buy. My first decision is always based on, 'Can I do this in a more sustainable way without sacrificing design?' If I can, then there is no reason not to.
I was brought up to understand that we are all here on planet earth together.
We try to make earth-friendly decisions whenever we can, as it's part of our brand DNA.
Sustainability goes across everything I do with Adidas and everything I do with my own house, so the Olympic kit is no exception. It is incredibly environmental in the way that it is manufactured. For example, there's no leather; it's free from PVC. There's lots of woven materials, which means a lot less waste.
You feel like everyone hates you if you've got a good life, now I feel maybe it's allowed because I've had my share of sadness.
My biggest surprises in my everyday job have to do with the challenges of trying to be slightly more responsible as a brand.
I think my differences were, and my differences still are, that I don't really approach fashion in a fashiony way.
We have captured a luxury and richness with our fur-free fur, which is proof to the fashion industry that killing animals for the sake of fashion is unnecessary.
My job at the end of the day is to design timeless, desirable, beautiful products. It's not about just designing a bunch of organic jumpers. I have a balance within the brand. If you try to create something people enjoy, and it happens to be made in a responsible way, then that's when you can really strike an incredible balance.
When I first started, it was a dirty word to say you made clothes for people to wear... I was a little ashamed of it. You didn't always feel you were this amazing creative force.
There's no excuse for fur in this day and age.
I think I always dreamt of having a brand that really was represented globally, that had a voice - that had a clear voice and a clear vision that made women feel great about themselves. That really spoke to women on a personal level. And that women could wear.
If you try to create something people enjoy, and it happens to be made in a responsible way, then that's when you can really strike an incredible balance.
I didn't want to be thirtysomething and not know what I was going to do. I was quite afraid of that, there were quite a lot of aimless kids around, in that 'other' side of my life, who didn't really know what to do because they always had a bank balance to fall back on and they were quite lost.
I'm incredibly sad that my mother's not here to see my kids and that my kids don't get to know her. And she didn't meet my husband. That's one of the hardest things. I don't even know how to put that into words.
I love a pocket. I'm about helping women look as good as possible on the least amount of effort. I want versatility and comfort. Clothes that can go from the office to anywhere. We're always trying on samples at work. If none of us would wear it, chances are no one else will.
Strength on its own in a woman is quite abrasive and not terribly attractive all the time.
I've had people say to me, 'You'll never sell handbags. You don't work with leather, and leather is luxury.' To me, it's the complete opposite: leather is everywhere - it's so cheap a material; it's so mass produced. Over 50 million animals a year are killed just for fashion. For me, it doesn't have a luxury element to it.
I'm a woman designing for women, and there are so many layers to that. On the one hand, it brings an effortlessness, but it also means that I think and overthink every detail, whether it's physical or mental or even - in some sense - spiritual.
The beliefs I was raised with - to respect animals and to be aware of nature, to understand that we share this planet with other creatures - have had a huge impact on me.
It's more expensive for me to make my shoes. I don't use animal-based glues or fish-based glues. So that costs me more. And, you know, like anything in life - mass marketing of anything - mass manufacturing of anything costs less.
I've got my organic veg patch and fruit; we're very garden-obsessed, my husband and I. He designed a garden for me for Christmas, so beautiful! Alasdhair's very good at the proportion and ground work, and I come in and do the planting and the color scheme.
I don't plan massively in advance.
For me, singing is the most natural thing in the world. I've grown up with it and I know I've got that gift.
Asia has always been a really exciting part of the world for me, personally. And it actually was the first part of the world that bought my brand, strangely enough.
I grew up on an organic farm in England. And I was a vegetarian from an early age - not just for health, not for the environment - just because I didn't believe in killing animals to eat them.
Growing up, I was always really inspired by Disney, and I had a great love of everything they created. My mum was huge fan, and she used to collect stills, and so they were all around the house, and we very much grew up on the early Disney films.
Obviously, we live in a society where ageing is feared. But, to me, the alternative to getting old isn't that great. I've got friends much older than me and much younger, and I love that. It means you get to teach as well as learn.
It wasn't easy navigating publicity when I started, because I grew up with 'being famous,' and I'm just not into it, and I guess defensiveness gets read into that. And I didn't get an easy ride at the beginning.
As a British fashion designer, it is an amazing, once-in-a-lifetime opportunity to be creative director of Team GB as the hosting nation of the London 2012 Olympic Games.
Pretending that the fashion industry isn't in part based on leather would be quite stupid of me, but at the same time, there is another way of doing things - even outside of leather. I don't use PVC either, for example, because it is harmful.
I'm obsessed with not chucking away food. I'm lucky enough to have a gardener, so we grow sweetcorn, tomatoes, beetroots, cabbages, pumpkins, lettuce. I'm trying to get into blanching it and freezing so I don't have to buy veg over the winter, but then you need loads of freezers, and that's not ideal.
When I say I don't do fur or leather, in my world it's a massive shock, but when it comes into the sporting arena, it goes without saying. It also influences what I do on the runway: I get really excited when I discover an environmentally-friendly print process that doesn't use water, and I'll try and mimic that in my ready-to-wear.
I personally love sportswear, and love using it in high fashion.
I like doing slightly masculine, Savile Row tailoring. A nice jacket. Wearable - it's almost a dirty word in fashion, wearable, but that's what I do.
I can debate for weeks whether a trouser should sit on the waist, or a centimetre below, or on the hip, whether it should have a zip or a button, because I find personally that a detail like that can have a massive impact on how I carry myself that day. If I wear a slouchy jean, that will affect my posture and my whole manner.
I feel like a different person since my mum passed away, like I'm driving a ship with my husband alongside me and we're leading these four children into unknown waters.
My mum had a massive influence on me, not just in what she wore and how she looked, but in her spirit. She was married to one of the most famous men in the world, and she didn't wear any makeup, ever. I mean, have you ever seen the wife of a man like that rock up with no makeup on? Because I haven't since.
I think the moment that I'm very proud of is building a business without using animals. And, hopefully, changing people's perception of how you can do luxury fashion.
We always had our own vegetables growing up and now I'm doing it with my kids at our house in the country.
When I first started designing sportswear, I felt that women weren't represented in sports performance. I felt that men were dressed really well both technically and visually, and women were almost like an afterthought.
Very early, I thought I would go into music, but I was aware that it would bring a set of obstacles I didn't find particularly attractive. Also, I'm not a great performer! For a while, I thought I would do something in landscape gardening. But it was always fashion for me.
My mum and dad had creative jobs, but our family was a working family - so there wasn't an option of, 'Oh, when you're older, you're not going to have to work.'
I can honestly say this industry hasn't made me neurotic about my looks, except maybe my weight. I hope my clothes kind of reflect that. They're meant to make you feel good.
I literally have meetings at eight o'clock in the morning, and I finish at nine o'clock at night. It sounds pathetic, but I don't even have time to go shopping.
It's immoral that people make money out of writing crap, but I try not to obsess about it. I don't want to spend my life being angry.
