Status of Green House Emission at Global Level

By -

 

Greenhouse gas (GHG) emissions vary significantly across different regions, countries, and continents, influenced by factors such as industrial activity, energy production methods, population, and economic development. Here’s a detailed breakdown of GHG emissions on a continent-wise basis:

1. Asia

  • Global Share: Asia is the largest emitter, contributing over 50% of global GHG emissions.
  • Key Contributors:
    • China: The world’s largest emitter, primarily due to its vast industrial base and reliance on coal for energy.
    • India: The third-largest emitter, with a growing industrial sector and high reliance on coal.
    • Japan, South Korea, and Indonesia: Significant contributors, with emissions driven by energy consumption, industrial processes, and deforestation (in the case of Indonesia).
  • Trends: Rapid urbanization, industrialization, and economic growth are key drivers of emissions, with efforts in renewable energy adoption and efficiency improvements beginning to take effect.

2. North America

  • Global Share: North America accounts for approximately 18% of global GHG emissions.
  • Key Contributors:
    • United States: The second-largest emitter globally, with emissions primarily from transportation, energy production, and industry.
    • Canada: Significant emissions from energy production, particularly oil sands, and transportation.
    • Mexico: Lower emissions relative to the U.S. and Canada, with contributions from industry, agriculture, and energy production.
  • Trends: The region has seen a gradual decrease in emissions due to shifts towards renewable energy, energy efficiency, and policy measures, although fossil fuel usage remains high.

3. Europe

  • Global Share: Europe contributes around 8-10% of global GHG emissions.
  • Key Contributors:
    • Germany, United Kingdom, and France: Major emitters within Europe, largely due to industrial activities, transportation, and energy production.
    • Eastern Europe: Countries like Poland have high emissions due to coal dependency.
  • Trends: Europe is leading in emission reductions, driven by stringent regulations, a shift to renewable energy, and the EU’s commitment to carbon neutrality by 2050.

4. Africa

  • Global Share: Africa accounts for roughly 4% of global GHG emissions.
  • Key Contributors:
    • South Africa: The largest emitter in Africa, primarily due to coal-based energy production.
    • Nigeria and Egypt: Significant emissions from oil and gas production, deforestation, and agriculture.
  • Trends: While overall emissions are low, Africa faces challenges in balancing development and emissions, with increasing focus on renewable energy projects and sustainable practices.

5. South America

  • Global Share: South America contributes about 3-4% of global GHG emissions.
  • Key Contributors:
    • Brazil: The largest emitter, with deforestation (especially in the Amazon) and agriculture as key drivers.
    • Argentina and Venezuela: Significant emissions from agriculture, oil, and gas production.
  • Trends: The region is increasingly focused on reducing deforestation and promoting sustainable agriculture, but challenges remain in curbing emissions.

6. Oceania

  • Global Share: Oceania accounts for about 1.3% of global GHG emissions.
  • Key Contributors:
    • Australia: The largest emitter, with coal-based energy, agriculture, and industry as major sources.
    • New Zealand: Emissions largely from agriculture and energy.
  • Trends: There’s a growing push towards renewable energy and reducing dependence on fossil fuels, but fossil fuel exports remain a significant challenge.

7. Global Overview

  • Total Emissions: Global GHG emissions were approximately 50 billion metric tons of CO2-equivalent in 2022.
  • Major Sectors: Energy production (especially fossil fuels), industry, transportation, agriculture, and deforestation are the largest sources.
  • Trends: While some regions are reducing emissions, global levels continue to rise, driven by economic growth in developing nations. International efforts such as the Paris Agreement aim to curb global emissions, but significant challenges remain.

Conclusion

Global GHG emissions are concentrated in specific regions and countries, with Asia and North America being the largest contributors. Efforts to reduce emissions vary widely, with Europe leading in reductions, while other regions, particularly in Asia and Africa, face challenges balancing development and sustainability. Achieving global emission reduction goals requires coordinated international efforts and significant changes in energy production, industrial practices, and consumption patterns.

Solar panels installed on the roof with a capacity of 11.5 MW in Punjab state in India India’s solar mission which has kept at a target of 175 GW and the government is trying to keep its word to generate power from all kinds of Renewable Energy Resources. As it is focused on Solar, Wind and Biomass power generation technologies. We all know that a roof is the zero cost of land and uses the space for solar panel installation. There is no requirement of a special setup is installing the solar roof. Depending upon the roof size and shading and direction of the sunlight is considered for setting up the solar panels. But, most of them have small or medium roofs that can generate in kiloWatts (kW) or Megawatt (MW) scale. In Amritsar, there is an installation od 11.5 MW capacity of a solar power plant which is completely covered with solar roof which will benefit 8000 households was built by Radha Saomi Satsang Beas (RSSB), a religious organization in Punjab.

In most of the western countries and developing countries are launching the new concept called the “ Recycling Malls ” in major cities and towns across their countries. The main objective of the recycle mart is to sell the used products (ex: used plastic, glass, paper, etc.). This is an innovative way of making things and helping in reducing environmental pollution in the surroundings across the globe.   There are different kinds of pollutions that are generated effecting Air, Water, Land, Food, Sea, Ocean pollutions. It is damaging the EARTH gradually and impacting directly and indirectly that are highly toxic and increase the scope of new harmful viruses etc.   Issue: Wastes are different types that are generated in the world which is mostly produced by man. Anything that is produced excess and unable to control is added into pollutant list. The recycling plants are getting adopted across the globe with different techniques, methodologies and Strategic ways in collection

India is witnessing a new chapter in the growth of the renewable sector, mainly in the solar sector. Hence, any new breakthrough in the field of solar cells and solar power generation is beneficial for India. New technology is being developed in the University of Chicago within the confines of its chemistry laboratory by Professor “Luping Yu”. A new kind of solar panel was designed and manufactured which has a higher efficiency when compared with the currently running modules used for power generation. The given polymer solar cell consists of a new polymer, called "PID2". The new polymer improves the efficiency of electrical power generation by 15 per cent when added to a standard polymer-fullerene mixture.
