Sustainability makes good business sense, and we're all on the same team at the end of the day. That's the truth about the human condition.

If we all act together - business, governments, NGOs and citizens and, especially, the young - just imagine the good we could create.

I don't subscribe to, 'Here are the top ten tips to successful leadership,' or, 'How to learn leadership in ten minutes.' A leader is someone who gives positive energy to others which then results in a better change than would have happened. I think everyone is a leader.

Safe working conditions, fair wages, protection from forced labor, and freedom from harassment and discrimination - these must become standard global operating conditions.

The moral case for gender equality is obvious. It should not need any explanation.

My own fear, if I have one myself, is a fear of being obsolete. This is a world that changes very fast, and one of the main human desires is to belong to, to be part of, something. It's probably one of our greatest needs next to oxygen.

Looking at the world through a sustainability lens not only helps us 'future proof' our supply chain, it also fuels innovation and drives brand growth.

When we empower women, society benefits, grows, and thrives.

Renewable energy could reduce emissions but also create jobs and improve public health.

Purpose has always been part of Unilever's DNA. Our founder, William Lever, built a business around the sale of Lifebuoy soap that was not only profitable and sustainable but also helped transform the health of the poor in Victorian Britain.

Leadership is not a contest of likeability. Leadership often boils down to making the tougher choices. You are not in a popularity contest.

My father worked in a tyre factory. My mother worked as a teacher.

Every few decades, we have an opportunity to make a drastic change to the way we live our lives. We get a chance to design the building blocks of our daily routines, the infrastructure that will support and accompany us for the years to come - from the trains and trams we ride, the offices we work in, to the energy that powers our homes.

It cannot be right in a world of increasing human progress - whether in medicine, space exploration or renewable energy - that so many people are denied the most basic human rights.

The world faces enormous human development and environmental challenges, from poverty and disease to food security and climate change.

We can no longer pretend that business is immune from the rising tide of environmental or social challenges or that companies can create value in isolation from the communities of which they are a part.

The great challenge of the 21st century is to provide good standards of living for 7 billion people without depleting the earth's resources or running up massive levels of public debt. To achieve this, government and business alike will need to find new models of growth that are in both environmental and economic balance.

Land is a great example of how we can manage and invest in sustainable infrastructure for economic, social, and environmental gains. Its use - and misuse - is at the heart of the challenge for food, fuel, and fibre.

Practically, systemic thinking can be used to identify problems, analyze their boundaries, design strategies and policy interventions, forecast and measure their expected impacts, implement them, and monitor and evaluate their successes and failures.

We need more food, more forests, better livelihoods for smallholder farmers, and lower emissions. If we want any of them, we must have all of them.

Large-scale deforestation can be prevented while increasing food production through better, smarter agriculture.
