Climate Variability and its Causes

Earth’s climate has always been affected by a range of natural factors. It is known to have changed significantly during recorded history, even before gaseous emissions from human activity could have posed any significant threat to atmospheric or climatic conditions. Natural climate variability can arise from natural forcing mechanism which includes both internal oscillations and […]

Evolution of International Environmental Law

Protection of environment has become a major part of international law. International environmental law is developed between sovereign states to develop standards at the international level and provide obligation for state including their behaviour in international environmental matters. International law is created by collective actions of nearly 200 countries around the word, which is not […]

This year, the air quality during the winter hit a record low as per global standards which not only caused massive disruption in daily activities but also created a mass public health crisis with spike in patient population with asthma and lung and […]

Introduction to Environmental Product Labelling

Environmental product labelling is a way to promote consumer behaviour and sustainable development, as identified by Agenda 21 of Rio Earth Summit in 1992.  This has not only led to internalization of environmental impacts and the issues associated with products and their manufacturing processes but also influenced consumption behaviour of the people. As a result, rapid […]

An Introduction to Greenhouse Gases

Greenhouse gases are generally any gas molecules or compounds in the atmosphere which interact with outgoing infrared radiation from the sun and thus contribute to the Greenhouse Effect by warming the atmosphere. The major constituents of the atmosphere such as nitrogen (N2) and oxygen (O2) do not interact with infrared radiation and, thus are not […]

Construction Waste Management Strategy

From management point of view, no single management strategy is suitable for managing all the construction waste steam in all circumstances. A sustainable construction waste management strategy includes a range of comprehensive strategies such as reduce, reuse and recycle. Effective waste management strategies require source segregation of all wastes generated during the construction. Construction contractors can […]

Urban Heat Island Effect: Causes, Impacts and Mitigation

The urban heat island (UHI) effect arises due to absorption of incident radiation from the sun by built surfaces of tall buildings, roof, concrete structures and asphalt roads and then releasing it in the form of heat. The term “urban heat island” describes the built-up areas that are significantly hotter than the surrounding open, natural […]
