Carbon Credits: Are these measures enough?

One of the most significant areas where the private sector was involved in the carbon off-shooting measures was through the Carbon Trading scheme (Stern, 2007). This is one of the important methods of taxation aimed at attempting to reduce the growth of carbon in the environment, with the dual objectives of discouraging the obsolete, mainly fossil-fuel based technologies and limiting their use in the future and at the same time, providing incentives for transition towards greener technologies. Carbon Credits or the carbon off-setting measures, i. e. putting a price on carbon are an encourage­ment and are vital for this transition. While different countries have different pricing mechanisms, they could achieve their stated goals to a certain extent during the last few years.

GREENING THE ECONOMY: THE CHALLENGE

The awareness is growing by the day on the harmful effects of the fossil fuel related economy on the health of human beings, thanks to the newer research findings and the theme often promoted in various media and due to the awareness campaigns launched by the NGOs.

While there is such a widespread, growing realization and the eagerness to address the issues, there is still a wide gap between the assumptions and the work actually done in undertaking remedial measures. The reason is far from simple-historically, the usage of fossil fuels has dominated the source of energy needs of human beings...

Green Energy

“Green energy’’ is often understood in the context of renewable energy and sustainable development by most governments and inter-governmental organizations. The con­cept of a green economy envisages an environmental friendly, green way of producing energy. Green Economy is still an evolving concept, but primarily could be understood as a system where certain sectors like renewable energy contribute in a major way to a country’s economy. It should also visualize revolutionary changes without compro­mising on the people’s aspiration for a good life. A green economy should enhance people’s quality of life, not just “without compromising’’ it.

The United States Environment Protection Agency (EPA) describes green energy as “a subset of renewable energy and represents those r...

The Urgency

On a global level, it is estimated that for each year of delay in taking appropriate policy decisions (steps towards green economy) costs an additional 500 billion US dollars, in terms of mitigation costs between now and the year 2030 (IEA, 2009). The proposals by the government to alter any large-scale socio-technical systems to enable sustainable development goals are highly uncertain policy projects. The adoption of such policies might also lead to highly unfavourable domestic political climate—as it means giving preference to long-terms interests over the short-term pain. Some actions may affect the leaders’ political survival due to some hard decisions that have to be made...

The challenges in the energy sector

The challenges we face owing to the dependence on fossil fuel based economy are enormous and are growing by the day. Today, the world still relies primarily on fossil fuels as its main source of energy. Fossil fuels are expected to account for 77 per­cent of the increase in demand between 2007 and 2030 (IEA, 2009). The demand for electricity is projected to grow by 76 percent during the same period, requiring a staggering capacity addition of another 4 800 gigawatts (GW), which is almost five times the existing capacity of the United States. The Report also estimates that still 1.3 billion people will lack access to electricity in 2030, compared to the 1.5 billion people today. Universal electricity access could be achieved with additional

power-sector investment of $35 billion per year ...

Ways of “greening the economy’’

Jayaraj Manepalli, Vienna

23.1 INTRODUCTION

“Green energy’’ is a term used to describe the energy that is generated from the sources that are known to be non-polluting. Adopting the green energy measures is an environmental-friendly way of generating power—as it is a remedy not only for the harmful effects of pollutants on our environment over the years but also useful to prevent future global warming. Any green energy policy is a result of a particular government’s commitment for the environment and promotion of particular forms of technologies, apart from its own business and geo-political interests...

DECARBONISING INDUSTRY

The whole saga of modern economic growth started with the industrial revolution, which is also the cause of earth’s changing climatic equilibrium. Anthropogenic emis­sions due to industrialization fuelled by fossil fuels still continue to be the major reason for Global Warming. They will be continuing their contributing role till 2030, the date by which carbon emissions are to be stabilized, to decline afterwards. Towards such a goal, we need to de-carbonize the industrial sector through the overall improvement of efficiency, technology and utilization.

Decarbonising industry is an all-encompassing term, which includes most of the productive activities...

DECARBONISING BUILDINGS

Buildings use energy for heating, cooling and illumination. Besides, there are many appliances and other electric systems such as lifts, elevators, refrigerators, stoves and many other domestic appliances. Apparently, major part of energy is used for heating, cooling and illumination. The world average per-capita energy use is considered as 2,000 W, which varies from 600 W for Bangladesh to 12 000 W for United States. It is not necessary to use 12 000 W of energy to have a life with modern amenities. The Swiss Federal Institute of Technology developed the concept of a 2 000 Watt society. According to this frame work, US energy use has to be drastically cut down by 80 to 83 percent, and Western Europe (W. Europe’s per-capita energy use is 6 000 W) by 67 percent (Yudelson, 2009)...
