PRESIDENT OF INDIA INAUGURATES NATIONAL CONFERENCE ON ‘ENVIRONMENT – 2025’
IT IS OUR MORAL RESPONSIBILITY TO PROVIDE A LEGACY OF A CLEAN ENVIRONMENT TO THE COMING GENERATIONS: PRESIDENT DROUPADI MURMU

The President of India, Smt Droupadi Murmu inaugurated a two-day National Conference on ‘Environment – 2025’ in New Delhi today (March 29, 2025).
Speaking on the occasion, the President said that all days related to the environment give the message that we should keep their objectives and programs in mind every day and make them a part of our daily life as far as possible. Environmental protection and promotion will be possible only through continuous activism based on awareness and everyone's participation.
The President said that our children and the younger generation have to face and contribute to environmental transition on a much wider scale. She highlighted that elders in every family worry about which school or college their children will study in, and what career they will choose. This worry is justified. But, we all also have to think about what kind of air our children will breathe, what kind of water they will get to drink, whether they will be able to hear the sweet sounds of birds or not, whether they will be able to experience the beauty of lush green forests or not. She said that these topics have economic, social, and scientific aspects, but the most important thing is that the challenges related to all these topics also have a moral aspect. It is our moral responsibility to provide a legacy of a clean environment to the coming generations. For this, we will have to adopt an environmentally conscious and sensitive lifestyle so that the environment is not only protected but also enhanced and the environment can become more vibrant. Balancing clean environment and modern development is both an opportunity and a challenge.
The President said that we believed that nature, like a mother, nourishes us, and we should respect and protect nature. The basis of the Indian heritage of development is nourishment, not exploitation; protection, not elimination. Following this tradition, we want to move forward toward a developed India. She was happy to note that over the last decade, India has achieved several examples of early completion of its Nationally Determined Contributions as per international agreements
The President said that the National Green Tribunal (NGT) has played an important role in the environmental governance of our country. It has played a decisive role in the field of environmental justice or climate justice. The historic decisions given by NGT have a wide impact on our lives, our health, and the future of our earth. She urged the institutions associated with the environment management eco-system and citizens to continuously strive for environmental protection and promotion.
The President said that our country and the entire world community have to follow a path that is environment friendly. Only then will humanity make real progress. She stated that India has presented many exemplary examples to the world community through its green initiatives. She expressed confidence that with the participation of all stakeholders, India will play the role of green leadership at the global level. She said that we all have to make India a developed nation by the year 2047 where the air, water, greenery, and prosperity attract the entire world community.
The National Conference on ‘Environment – 2025’, being organised by NGT, aims to bring together key stakeholders to discuss pressing environmental challenges, share best practices, and collaborate on future action plans for sustainable environmental management.
To achieve acceptable indoor air quality, ventilation systems should aim for at least 5 air changes per hour (ACH) or 30 cubic feet per minute (cfm) per person, using a combination of natural and mechanical ventilation.
ReplyDeleteHere's a more detailed explanation:
What is acceptable IAQ?
Acceptable indoor air quality (IAQ) means air with no known contaminants at harmful concentrations, as determined by authorities, and with which a substantial majority of people exposed do not express dissatisfaction.
Ventilation's Role:
Ventilation helps remove or dilute indoor airborne pollutants, improving IAQ.
ASHRAE Standards:
The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) provides standards for ventilation and IAQ.
Standard 62.1: This standard specifies minimum ventilation rates and other measures to ensure acceptable IAQ and minimize adverse health effects.
Standard 62.2: This standard focuses on ventilation in residential buildings, recommending 0.35 air changes per hour, but not less than 15 cubic feet of air per minute (cfm) per person.
Ventilation Methods:
Natural Ventilation: Opening windows and doors to allow fresh air in.
Mechanical Ventilation: Using fans, HVAC systems, and other equipment to introduce outdoor air.
Calculating Ventilation Needs:
Air Changes per Hour (ACH): Aim for at least 5 ACH.
Cubic Feet per Minute (CFM): Consider 30 cfm/person or 5 CFM per 100 square feet of floor area.
Factors Influencing Ventilation:
Occupancy: Higher occupancy may require higher ventilation rates.
Activities: Activities that generate pollutants (e.g., cooking, cleaning) may require more ventilation.
Building Type: Different building types (residential, commercial, etc.) have different ventilation requirements.
Improving Ventilation:
Strategic Window Placement: Position windows to maximize airflow.
Vent Placement: Ensure proper placement of vents for efficient air circulation.
Material Choice: Use low-VOC (volatile organic compound) building materials.
Air Cleaners: Consider using air cleaners to remove pollutants from indoor air
A healthy adult typically inhales around 11,000 to 12,900 liters of air per day (or roughly 11 to 13 cubic meters), depending on activity levels.
ReplyDeleteHere's a more detailed breakdown:
Breathing Rate:
Healthy adults breathe in and out between 10 and 15 times per minute, depending on activity.
Tidal Volume:
The amount of air inhaled or exhaled during a normal breath (tidal volume) is about 500 milliliters (0.5 liters).
Daily Air Intake Calculation:
With 12 breaths per minute and a tidal volume of 500 mL, that's 6 liters per minute (12 breaths/min * 0.5 L/breath). In a day (24 hours * 60 minutes/hour), that's 6 L/min * 1440 minutes = 8640 liters, or 8.64 m3.
Variations:
This is an average, and the amount of air inhaled can vary significantly based on activity levels, stress, and other factors.
EPA Exposure Factors Handbook:
The U.S. EPA's Exposure Factors Handbook suggests that an adult male of normal weight with moderate activity consumes around 22.8 m3 of air per day.
