Vast Solar and Mineral Resources at Risk of Being Left Untapped

By Rochelle Toplensky

 

This week: Burgeoning biodiversity credits; rocking carbon removals; cooling coatings

Welcome back. More than half of the world’s best solar resource is in Africa. The continent also has 80% of the world’s platinum reserves, half of all cobalt reserves, 40% of manganese reserves and great potential for hydroelectric and wind power. But these riches are largely untapped and will remain so without significantly improved access to capital, according to a new report published by the International Energy Agency in partnership with the African Development Bank on Wednesday.

There are a variety of reasons why investment lags, but the bottom line is that the cost of capital for Africa is just too high. Borrowing costs on a large-scale renewable energy project on the continent are triple those of a similar one in advanced economies and China. Smaller projects are even worse.

The Global South has taken a novel approach to solving this: Proposing financial innovation to cut this emerging-market premium. It started with the Bridgetown Agenda at last year's climate conference and has gained momentum. This week’s first ever Africa Climate Summit

proposed financial system changes, along with a host of new carbon taxes. While the taxes remain hotly contested, financial innovation could actually happen.

Why it matters

Higher investment would bring green electricity and cleaner, more efficient cookstoves to hundreds of millions of Africans, fostering health, development and growth in a continent with a fifth of the world’s population.

And if that isn't enough, the commercial reality is that the Global North needs these resources to transition our economies to clean energy. After all, we are racing to break our reliance on Chinese suppliers of critical minerals and metals.

If some of these financial innovations succeed, projects in the region should offer compelling returns to both locals and investors.

There are strategic considerations too: While many in the West have been stepping back, China has been investing heavily in the region, albeit with mixed results.

Key takeaways

Continued efforts to overhaul the international financial system can feel remote, but as with a small wording change in a tax law, these details can have significant implications. Financial innovations that succeed in cutting the emerging-market risk premium hold great promise, both for the developing world but also for the companies, industries and investors in the energy transition.

Zeroing In on the Data

Biodiversity credits could be key to funding the conservation of the Earth’s ecosystems, but setting up a functioning market to buy and sell these payment tokens won’t be easy, writes Joshua Kirby.

Protecting the world’s diversity of plants and animals has a direct bearing on the economy and companies: Around half of global output—some $44 trillion—is dependent on nature, according to research from the World Economic Forum. Roughly $600 billion to $800 billion more a year is needed to halt and repair the damage done to the natural world by global industry and agriculture, according to the think tank Paulson Institute.

One potential funding source is the nascent biodiversity-credit markets. While some biodiversity-credit systems have already begun, they will need to surmount the problems of carbon-offset markets, as well as some of their own.

Rocking Carbon Removal

Most of the world’s efforts to remove carbon from the atmosphere use giant, vacuum-like devices that suck in air and isolate the carbon. Microsoft is funding a new approach that uses crushed-up limestone to achieve the same result, writes Amrith Ramkumar. 

The tech company said Thursday it agreed to buy credits from startup Heirloom Carbon for the removal of up to 315,000 metric tons of carbon dioxide over 10 years. That would amount to a purchase commitment of at least $200 million based on market prices and would offset the equivalent of the annual emissions of around 70,000 gasoline-powered cars.

The deal will help Microsoft neutralize its carbon emissions and is one of the largest ever purchases of carbon-removal credits.

Quoted

“All of these different components are really what you need to see this [carbon removals] industry take shape.”

— Shashank Samala, chief executive of Heirloom Carbon

Cooling Coatings

CREDIT: GAF

Cities across the U.S. have found relief from this summer’s record-setting heat with the help of technologies that shield roofs, pavement and other surfaces from the sun’s scorching rays, writes Eric Niiler.

Some of these technologies have been around for more than a decade but are experiencing greater demand as global temperatures rise. While others—such as super-reflective coatings for pavement, streets and windows—are just now becoming effective and affordable enough for widespread use.

The Big Number

40

Green roofs can be up to 40 degrees cooler than a similar-size blacktop roof while also cutting waste heat from air-conditioning units.
