Nitrogen management policies introduced in the past decades by some OECD countries have succeeded in reducing excess nitrogen use by farmers, but half of global mineral fertiliser use is still lost for crops. While about half of OECD countries have nutrient surpluses of between 25-50 kg N per...

The rapid and deep emissions reductions needed to keep global warming to 1.5°C rely critically on an immense scaling-up of investment in clean energy technologies. The cost of capital plays a key role in determining investment decisions and, when elevated, can pose a significant barrier to...

This study investigates the impact of firms' emissions on their investments in renewable energy. Stricter environmental regulations are aimed at incentivizing firms to invest in low-emission/pollution technologies such as renewable energy. Recently, the People's Republic of China (PRC) announced...

Given the commitment of G7 and G20 countries to the gradual elimination of fossil fuel subsidies and their advocacy for other nations to follow suit, this study examines the effects of such subsidies on firms' GHG emissions. Utilizing a dataset comprising 3,359 firms across seven countries in...

The building and construction sectors contribute about 38% of the greenhouse gas (GHG) emissions and account for 35% of the total energy consumption. With the growing population (especially in developing Asia) and increasing income, the demand for construction and building will continue to rise,...

In order to reduce greenhouse gas (GHG) emissions and to achieve the Sustainable Development Goals (SDGs), Asian countries are trying to realize the potential of energy innovation. However, several structural issues might deter the expected impact of energy innovation on GHG emissions. Given the...

Since the mid-1980s, the international community has controlled refrigerants that may damage the ozone layer and cause climate change based on several international agreements. In particular, the Montreal Protocol contributed to not only solving the ozone layer depletion problem but also...

Maritime industry transports over 90% of traded cargo annually and accounts for 3% of global greenhouse gas (GHG) emissions. The Asia and the Pacific region process 64% of global cargo, has 9 of the largest 10 ports globally, and provide over 65% of seafarers employed in the industry to support...

There are major gaps in the measurement of the adoption and stringency of countries’ climate actions and policies, notably in a manner coherent across countries, time, sectors and instrument types. The climate actions and policies measurement framework (CAPMF) aims to fill this gap. It is a...

We develop the concept of aggregate emission targets, which are goals for national emissions but do not dictate the forms of regulation used to achieve the goals. We compare aggregate emission intensity, quantity, and price targets adopted at the national level but implemented cost effectively...
