There is no Planet B
We all have recently heard terms like global warming, net zero, climate change, and carbon footprints. Indeed it is a serious issue. Models show, avert dangerous levels of climate change. Global, carbon dioxide emissions must fall to zero by the end of this century. We must limit global warming to 1.5 degrees Celsius. Achieving net zero means neutralizing emissions and absorption of greenhouse gases.
Let’s dive into the challenges and solutions. Energy services and industrial processes, such as long-distance transport, air travel, reliable electricity, steel, and cement manufacturing, are difficult to provide without adding carbon dioxide to the atmosphere. According to the Global Fossil Fuel and Industry Emissions 2014 report, energy services like long-distance travel, cement, etc. constitute 27% of global CO2 emissions. The demand for these services makes carbonization of it both essential and urgent.
The electricity sector is the biggest problem, with India being the third-largest emitter. Coal power is the largest emitter in India. Although solar and wind power are promising solutions, they have challenges. The increasing power demand in India makes it difficult to just ask people to consume less energy, as India’s per-capita consumption is already one of the world’s lowest.
Solar and wind are affordable and sustainable but lack reliability. We need other sources to balance them out. We must be able to store 3-4 months of energy in energy banks so that we will be able to use it as per our requirements. Lithium ion batteries are good for powering our phones but not for the environment, replacements like pump hydro or zinc-air batteries can help. Electricity is comparatively an easier sector to achieve net zero, but other industries like flying, shipping, iron production, and cement require more effort to move away from fossil fuels.
We need to green our energies, triple our renewables, and slash down almost three quarters methane leaks. Choosing trains over flying, using public transport, cycling, and walking can make a difference. Electric vehicles are a better option, and their production is becoming cleaner as they are switching towards burning natural gases rather than coal. Concepts like carbon capture, zero-carbon airports, and jet fuels, oils from algae must be explored.
On an individual level, adopting a low-carbon lifestyle can make a difference. Simple steps like switching to LED lighting, choosing trains over flying, adopting minimalism, and our all-time but unsung mantra reducing, reusing, and recycling can help. However, social issues need to be addressed too. People need to understand the seriousness of the situation. Awareness programs should be implemented. Climate change education in schools with engaging activities can bring up new ideas. Appreciation and recognition for efforts to reduce global warming can promote more awareness.
We need to follow activists like; Greta Thunberg, Levi Draheim, Xiuhtezcatl Martinez, Licypriya Kangujam, etc. And take inspiration from them and become more active through our actions because…
The time for change is, NOW !
