The two-week-long UN Climate Change Conference (COP26) concluded with the negotiated terms detailed in the Glasgow Climate Pact. According to the International Energy Agency (IEA), in the most optimistic scenario where all the announced pledges are achieved, global mean temperature rise can be limited to 1.8°C by 2100. Even if complete implementation may be unlikely, in terms of ambition and ratcheting, COP26 has made progress, albeit incremental.

Climate change is increasing the risk of occurrence of natural hazard events at different scales and magnitudes across the world. In India, Chennai rains and the resulting floods are a recent example. While climate change is the prime factor, environmental degradation exacerbates disaster risk, affecting the degree of exposure of societies to floods, landslides, and other hazards. Conventional urban-flood-management approaches alone may fall short as they do not provide the services required to build resilience to deal with the heightened threats.

In recent years, perovskite solar cells (PSCs) have achieved a remarkable power conversion efficiency of 25.5%, indicating that they are a promising alternative to dominant Si photovoltaic (PV) technology. This technology is expected to solve the world's energy demand with minimal investment and very low CO2 emissions. The market has shown a lot of interest in PSCs technology. A technoeconomic analysis is a useful tool for tracking manufacturing costs and forecasting whether technology will eventually achieve market-driven prices.

India has 21 of the 30 cities with the worst air quality in the world. Every year, we keep exploring options to curb air pollution. The transport sector is a significant contributor to air pollution in the cities. The electric vehicle (EV) segment could play a key role in decarbonising the sector. However, to realise green mobility in its truest sense, electric vehicles (EVs) need to run on clean energy. India’s power grid is predominantly coal-based at the moment.

With the impetus provided by phase I and II of the Faster Adoption and Manufacturing of (Hybrid &) Electric Vehicles (FAME) scheme, many state transport undertakings (STUs) have started deploying electric buses (e-buses) in their fleet. However, there are considerable challenges that fleet operators face in doing so. The switch from traditional to e-buses involves a major transition to a not-yet-familiar area, mandating new technology considerations (for charging e-buses), as well as robust planning (to deal with the dynamic and complex operations of e-buses).

India has 21 of the 30 cities with the worst air quality in the world. The transport sector is a major contributor (40%–80%) to air pollution in the cities. Hence, decarbonising the transport sector with the deployment of electric vehicles (EVs)is a crucial step in mitigating air pollution. Running an electric vehicle in the USA leads to a greater reduction in CO2 emissions than running it in India since the grid energy (used by the EV) in India is predominantly generated using coal.

Phase II of the Faster Adoption and Manufacturing of (Hybrid &) Electric Vehicles (FAME) India is envisioned to introduce 7,000 e-buses across the country by 2024. This initiative has increased e-bus deployment at a rapid rate. However, the traditional bus operators are not yet familiar with the operational needs of e-buses. Unlike traditional buses that require refuelling, e-buses need frequent recharging to increase their operational range. This key difference calls for setting up the necessary electric infrastructure to meet the charging demand of e-buses.

Electric buses (e-buses) have caught the attention of the Indian public transport operators due to their ability to address the issues of rising greenhouse gas emissions, and air and noise pollution caused by conventional fuel buses. The Faster Adoption and Manufacturing of (Hybrid &) Electric Vehicles (FAME) II scheme envisages the deployment of 7,000 e-buses by 2024. In order to make this a seamless transition, an efficient charging infrastructure is imperative. Currently, depot-based plug-in charging is the most common method of charging e-buses in India.

The concept of SNEHA (Solution for Nutrition and Effective Health Access) was born in 2017 in the office of the Principal Secretary of the Department of Women and Child Development (DWCD) in Bengaluru, Karnataka. The challenge at hand was to expedite improvement in malnutrition management in the state. The National Family Health Survey (NFHS 4) report had recently been released, and it was sobering for the whole country.
