GAINS Pathways25

Description

Business-as-Usual (BAU)

Considers the socioeconomic, demographic, and the existing and planned air pollution control policies, measures, regulations that will resume in the future following the current practices.

2°C Warming Scenario (2°C-WS)

The 2°C-WS pathway incorporates projections for energy consumption, the transformation of energy systems, and economic activities within the framework of devising strategies to keep the warming level below 2°C temperature increase by the year 2100. Furthermore, it assumes the complete implementation of advanced emission control technologies.

Emission scenarios

Sectors

Local vs regional contributions

Emissions from the state itself, from the neighboring states, from other states within India, from outside India or transboundary pollution, and natural sources.

Sectoral contributions

Segregated into primary emissions (natural sources, power plants, industry, domestic, transport, waste, and biomass burning) and secondary PM2.5.
