Whistleblowers are vital in exposing corruption, fraud and mismanagement. Safeguards can protect and encourage people willing to take the risk of speaking out about these crimes.

Bribery in business remains widespread, distorting markets and hurting the public interest. But we can tackle it. We must press companies to adopt a zero-tolerance approach. Better external regulation is needed and markets must be more transparent.

Trillions of dollars are spent annually on public procurement. Corruption raises costs by up to 50 per cent. It also costs lives. But open procurement systems mean we can monitor bidding, so we can ensure taxpayers’ money is well spent.

Vast expenditure combined with a reputation for secrecy. The defence sector poses unique corruption risks. But greater openness can prevent corruption risks. And it won’t compromise national security.

Poverty and corruption can seem like separate issues. But they’re tightly linked. Successful development policies need anti-corruption measures. We must work with governments and aid agencies to integrate them. Then we’ll maximise their effectiveness.

We inform and promote the anti-corruption agenda in a range of intergovernmental groups and institutions

In a globalised world, corruption travels easily. It finds safe havens in countries with lax rules. International conventions are a powerful framework for cross-border prevention. But we must make sure governments enforce their measures fully.

Corruption in humanitarian aid is so shocking, it’s often taboo. But if we all discuss it openly, we can tackle it. There are many measures aid agencies, governments and communities can take. They need some investment. But they give huge returns.

Political corruption doesn’t just mean election rigging. Politicians can let private rather than public interests dictate policy. How can we stop this? By speaking out. By demanding accountability from leaders, we can build honesty in politics.

Fairness in the courtroom is everyone’s right. Yet people in many countries face biased judgements or demands for bribes. We must press for reforms to increase judicial honesty. And we must keep watching that rules are enforced.

Water is our most vital resource. But corruption makes it undrinkable, inaccessible and unaffordable. We must demand stronger regulations. And we need information, to check that policies are right and money goes where it should, so no one will go thirsty.

We all want the best possible education for our children. But corruption causes poor teaching and unequal access to schooling. Tighter regulations are essential. And we must track funds and resources, to make sure they end up in the classroom.

Vast sums of money are tackling our biggest challenge, climate change. Loopholes in regulations mean opportunities for corruption. But by monitoring developments and learning fast, we can reduce the risks.

Corruption in health means the difference between life and death. Poor people are worst affected. But if we’re watching, funds can’t disappear. With information on budgets and plans, we can ensure that health facilities give us the best possible care.

Sport is a multi-billion dollar business. And it has ties to political and private interests. This means fertile ground for corruption. But greater openness can prevent it. If we can monitor money and decisions in sport, we can ensure fair play wins through.

Many countries rich in oil and gas are home to some of the world’s poorest people. Wealth stays corruptly in the hands of the elite. We must demand openness in revenues, payments and activities. Then insiders can’t hide their actions or their profits.

Deforestation affects us all, threatening millions of livelihoods and causing massive greenhouse gas emissions. Corruption in the forestry sector only speeds this destruction. But it can be curbed, so that forests are preserved and forest products are sustainably harvested.

Information is power. When it’s not provided freely, corruption can thrive. Laws need to guarantee public access to information. Governments must proactively disclose it, and we must demand it. Then it’s hard for corruption to hide.
