A Circular Economy is based on efficiency in natural resource consumption. Reduction in solid and liquid pollution and emissions are built into the new and efficient production processes. To reduce solid and liquid waste, circular economy design is modifying the production process in many...

Biomass, a renewable energy source, has been viewed as "carbon neutral" - that is, its use as energy is presumed not to release net carbon dioxide. However, this assumption of carbon neutrality has recently been challenged. In 2010 two letters were sent to the Congress by eminent scientists...

The most prevalent and perhaps most popular climate policies in the U.S. are Renewable PortfolioStandards (RPS) that mandate that renewables (e.g., wind and solar) produce a specifiedshare of electricity, yet little is known about their efficiency. Using the most comprehensivedata set ever...

As reporting GHG emissions becomes mandatory in the financial sector, the methods by which emissions are calculated will grow in importance for their impact on the resulting metric. Progress is underway in both the public and private financial sectors to embed emissions accounting standards, but...

The aim of this paper is to analyses residential solar PV feed-in tariffs (FiT) policy history to inform the development of a sustainable flexible pricing regime to enhance the diffusion of energy storage, electric vehicles, solar PV installations and other distributed resources focusing on the...

Substitution of petroleum fuels with biofuels such as ethanol and biodiesel has been shown to reduce greenhouse gas (GHG) emissions. These GHG reductions can be traded in the emerging carbon markets, and methodologies for quantifying and trading are still being developed. The main challenges in...

The United States of America currently faces unprecedented challenges. If our nation fails to effectively answer these challenges - such as fragile national security, the worst economic crisis since the Great Depression, and potentially catastrophic climate change - we will lose our position as...

The Belt and Road Initiative (BRI) is an ambitious development project initiated by the Chinese government to foster economic progress worldwide. This study aims to investigate the dynamics of energy, economy, and environment among 42 BRI developing countries using an annual frequency panel...

This paper examines the energy savings, environmental benefits, and economic impact of green roof systems applied to a "micro" region in Western Turkey. This subdivision (Artur) in Karaağaç, Izmir, consists of 1729 residential units, mostly used as summer homes. The units are in 45m2, 60m2,...

This paper refines indicators to measure innovation in environment-related technologies, drawing on recent methodological advances that allow a more accurate assessment of environment-related innovation in a broader range of countries and covering a greater variety of the relevant technologies....
