Railway Science (Environment – Global Warming)

The MYC (“MOBILISE YOUR CITY”) initiative focuses on promoting sustainable urban mobility and addressing the challenges of increasing traffic, congestion, and air pollution in cities. MYC aims at supporting 3 big cities - Nagpur, Kochi and Ahmedabad. GreenHouse Gases - Carbon Dioxide, Methane, Nitrous Oxides, and Water Vapour.

Greenhouse Effect - A natural process that warms the Earth's surface. The main gases responsible for the greenhouse effect include carbon dioxide, methane, nitrous oxide, and water vapour. India's goal of achieving the net zero target by 2070.

Clean Development Mechanism (CDM): It allows a country with an emission-reduction or emission-limitation commitment under the Kyoto Protocol to implement an emission-reduction project in developing countries.

Recognized Gasses - Carbon dioxide (CO₂), Methane (CH₄), Nitrous oxide (N₂O), Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs) and Sulphur hexafluoride (SF₆).
The Kyoto Protocol is an international agreement setting targets for industrialised countries to cut their greenhouse gas emissions.
The protocol was agreed to in 1997 in Kyoto in Japan, based on principles set out in UNFCCC. It was also acknowledged that per capita emissions in developing countries are still relatively low.
China, India, and other developing countries were, therefore, exempted from the requirements of the Kyoto Protocol.

Carbon monoxide (CO) - A flammable, colorless, and odorless gas. It is found in burning fuels of cars, small engines, and furnaces. It readily mixes with blood and can cause toxication.
National Pollution Control Day - 2 December (The day is observed to honor the lives that were lost because of the Bhopal Gas Tragedy).
Pollutants example - lead, nitrogen oxides, ground-level ozone, particle pollution (often referred to as particulate matter), and sulfur oxides.
