The Best Investment Opportunity Ever: Investing In Nature 101

Nine years ago, I said goodbye to Wall Street and became an investment banker for nature. After a 24-year career at Goldman Sachs where I was a partner and led a number of key business units, I left the firm to become president and CEO of The Nature Conservancy (TNC), the world's largest environmental organization.

When I arrived, TNCalong with organizations like World Wildlife Fund, Environmental Defense Fund, the Union of Concerned Scientists, and many otherswas doing great work. Project by project, we were getting great things done for nature. But alas, as good as we were, it wasn't quite enough. You could say we were winning many battles but losing the war. Environmental harm continued. And looking aheadespecially with rapid population growth and the threat of climate changeour challenges would only grow more intense.

The big question: How do we get more done? And how do we ensure that more financial resources go toward conservation?

My answer: by getting the world to fully appreciate the opportunity to invest in nature.

Unlocking new sources of capital

Most environmental work to date has been funded by philanthropy and government grants. And a lot of great work has been accomplished. But theres a limit to how much you can do with traditional sources of funding.

As a former investment banker, I couldnt help myself. I kept thinking about whether there were other sources of capital we could draw on to scale up our work. Capital that wouldn't run out.

It seemed to me that investing in natureor "green infrastructure"might be the key to unlocking a powerful new source of capital for our mission.

How do we invest in nature?

Think of nature as infrastructuregreen infrastructure, in contrast to manmade gray infrastructure. Green infrastructure provides valuable services in the form of clean air to breathe, healthy water to drink, fertile soil to grow our food, abundant fish to eat, protection from floods and storms.

Investing in these services can provide very attractive returns for communities, businesses and governments. For example:

• Planting a new forest can be a cost-effective strategy for businesses to comply with air quality requirements.
• Adding rain gardens, porous pavement and artificial wetlands can help cities address stormwater runoffa leading cause of water pollutionat low cost.
• Restoring a coral reef can help protect people and property from floods and storms, reducing disruption and costs during times of disaster.
• Changing farming and ranching practices in a city's upstream watershed can improve water quality and reduce treatment costs for beverage companies and utilities.

These natural solutions can be great investments. Often, they work just as well asor even better thantraditional manmade infrastructure. They often cost less. And they usually deliver important co-benefits for freethings like habitat for plants and animals, green space in underserved neighborhoods and opportunities for recreation and tourism.
