With infrastructure reform, U.S. could build world’s biggest, greenest carbon sink
In the middle of last month, U.S. Sen. (and New Green Deal co-sponsor) Ed Markey (D-Mass) told Vox that his party would make sure that any overhaul of the country’s infrastructure was done with clean energy.
"If there is an infrastructure bill, we’re going to make it a green energy bill," he said. "We’re going to be submitting amendments that ensure that bill has aggressive renewable energy resource and energy efficiency standards, and that there are higher and stronger standards for federal renewable energy procurement."
But infrastructure goes beyond roads and bridges and into forests, farms, rivers and streams — all of which help us manage storm runoff and meet our needs for clean drinking water. U.S. cities such as Denver and New York already funnel water fees into forests, farms and fields, because that’s where their water comes from. The cities of Philadelphia and Washington, D.C., meanwhile, are using stormwater fee assessments to encourage investment in green spaces that absorb water instead of concrete ones that repel it.
These "green infrastructure" projects don’t just keep greenhouse-gas emissions down; they generate environmental benefits. Some even can become carbon negative, meaning they can absorb more greenhouse gas than they emit. (For details, see "New Green Deal Aims to Boost the Restoration Economy. But What IS the Restoration Economy?")
The green infrastructure boom
Green infrastructure is nothing new. In 2016, California legally recognized meadows and streams as part of its infrastructure. That year, we documented nearly $25 billion for green infrastructure spread across 62 countries in 2015 alone (see Alliances for Green Infrastructure: State of Watershed Investment 2016).
Research published in 2017 showed that green infrastructure can be dramatically cheaper to maintain than gray infrastructure. That makes intuitive sense, because forests and fields are living things that grow, while pipes and sidewalks crumble and decay, although in practice, almost all green projects are a blend of green and gray.
But green infrastructure increasingly features in large-scale infrastructure projects such as the one the U.S. is embarking on. The Association of Southeast Asian Nations (ASEAN) and the Asian Development Bank (ADB), for example, recently launched an effort to raise more than $1 billion for green infrastructure investments across the region.
Paying for ecosystem services
No one has yet said where the $2 trillion will come from or how it will be spent. If it materializes, it probably will come from a combination of user fees and tax increases.
No matter where it comes from, it should be dispensed based on performance. Regional governments around the country have been experimenting with so-called "pay for success" models (see "Nature, Paid on Delivery: Is Pay for Success the Future of Ecological Restoration?"), while the 2016 Ecosystem Marketplace report documents scores of projects that use payments for performance.
Many projects documented there involve a government or business partnering directly with landholders near its water source — such as a beverage company paying local farmers to reduce their pesticide use, saving money on on-site water treatment in the process — or paying into a local water fund.
An extra $675 million came from water users themselves — cities, companies or water utilities acting on behalf of customers — in an effort to proactively safeguard water supplies close to home. Cities and states moved to mitigate risks to water supplies, but also were motivated by the environmental and social co-benefits these projects delivered. Meanwhile, water utilities surveyed by Ecosystem Marketplace cited concerns about operational and maintenance costs as their core motivations for watershed investment. For the private sector, reputational and supply chain risks often motivated action, particularly in the food and beverage sector, which spent about $9 million in 2015. More broadly, the report highlights the growing popularity of corporate water stewardship, citing commitments by large, consumer-facing brands such as Coca-Cola, SAB Miller, and IKEA.
The report also covered developments in other, more "market-like" mechanisms for watershed investment. Water quality trading and offsets programs jumped from $20.8 million in transactions in 2013 to nearly $32 million in 2015, hitting an all-time high. And environmental water markets, which connect buyers and sellers of water use rights seeking to restore water to overdrawn river systems and aquifers, saw the U.S. surpass Australia for the first time as the worldwide leader in transactions ($48.4 million as of 2015). Environmental water markets are becoming more flexible and accessible to private investors, according to the report, making them a promising mechanism for conservation finance in the coming years.
These watershed investments are steadily gaining momentum, with transactions growing about 12 percent per year on average between 2013 and 2015, but the report notes that uncertainty around future regulations ranked as the top concern among project respondents.
