If green bonds are a viable tool to reduce emissions and adapt infrastructure to the effects of climate change, how can governments encourage the issuance, sales, and growth in the share of green bonds in the total bond market?
To achieve the Biden administration's blueprint for solar energy and focus on climate change mitigation and adaptation, green bonds may be worth considering. But, like any other financing instrument, they may be best considered through a cost-benefit lens.
The past two years have witnessed increasingly vocal calls for rapid decarbonization of the global economy through a clean energy transition. How can Congress ensure that new costs associated with a clean energy transition do not fall disproportionately on lower-income ratepayers?
Almost every country has pledged to slash carbon emissions to slow the gears of global warming. Costa Rica's plan provides a glimpse of what a carbon-neutral future will look like. It shows how nations can take action and make investments that hold up, regardless of what future comes to pass.
Micromobility was positioned as a solution for every urban problem from traffic congestion to air pollution to transit deserts and inequality. Is there a way to know if micromobility can fulfill these ambitious goals?
Unleashed in Santa Monica, California, last September, Bird and its competitors are now in 30 American cities and counting. Cities are responding to the scooter takeover with new regulations and increased law enforcement. But if officials rely only on 20th-century tools to integrate these 21st-century scooters into their cities, they will miss a big opportunity.
Demand for rooftop solar panels is soaring among U.S. homeowners. Meanwhile, states are struggling to adapt a 20th-century electrical grid—and the corresponding cost structure for electricity rates—to this 21st-century reality. This is causing confusion and uncertainty.
While biomass will almost certainly never become the dominant fuel for the electricity sector in the United States, it is still worth including as part of a menu of greenhouse gas mitigation strategies.
Leaving the future of America's electricity grid to chance should not be an option. To maximize the potential benefits of a multibillion-dollar smart grid investment, a closer examination of technology and policy is needed.
China's economic transformation over the last three decades has produced potentially deadly air pollution its people inhale every day. But an investment of $215 billion annually could substantially reduce pollution, lessen its drag on productivity, spare the lungs of countless people, and save lives.
South Africa’s landfills are reportedly rapidly reaching capacity—as are those in many developing countries. Surveys show that only about 3 percent of urban South Africans sort and recycle their household waste frequently. Until recycling becomes more widespread, the nation will have to keep building landfills.
Stopping climate change will require the United States and the rest of the world to virtually eliminate emissions over the course of the 21st century. Getting anywhere close to zero emissions demands sustained political and public support, driven by an energy production sector given enough incentives to make carbon reduction succeed.
Demand for photovoltaic solar panels still primarily depends on government subsidies, as in most parts of the world solar power remains more expensive than conventional sources of electricity, says Keith Crane.
Technological development challenges suggest that it is highly unlikely that advanced approaches for producing hydrotreated renewable oils suitable for military applications will constitute an important fraction of the commercial fuel market until well beyond the next decade, writes Keith Crane.
A carbon dioxide tax with refund is fair because the people responsible for the most emissions would pay the most. The tax would also be progressive. Many Americans with lower incomes would find the refund would more than defray the higher costs of gasoline and electric power, write Keith Crane and James Bartis.
