We have roughly four years of emissions left at current levels in the 1.5°C carbon budget. While 119 countries, representing 74% of global emissions, have updated their Nationally Determined Contributions (NDCs), they remain insufficient to limit global temperature rise to 1.5 degrees C [1]. Even under the latest NDCs, global temperatures are projected to rise by 2.3 – 2.8 degrees C
[1].
Public discourse on climate change mitigation has largely focused on carbon dioxide emissions. While CO2 is the largest contributor to long-term warming, Short-Lived Climate Pollutants (SLCPs) account for nearly half of current warming [3.4]. These pollutants remain in the atmosphere for relatively short periods but have significantly higher near-term warming potential. For instance, black carbon, with an atmospheric lifetime of roughly 12 days, has a global warming potential of 1,055 –2,240 times that of CO2 [5]. Despite this, climate policy continues to rely on 100-year Global Warming Potential (GWP100) metrics, which understates the urgency of addressing these pollutants [6].
SLCPs also impose significant environmental and social costs, particularly in the Indian context. Black carbon emissions in the Indo-Gangetic Plains, driven by industrial activity, biomass burning, and the use of inefficient household fuels, accelerate glacier melt in the Himalayas, threatening long-term water security. High ozone concentrations have also been linked to substantial agricultural losses in the Indo-Gangetic Plains [5]. These pollutants are also a major contributor to air pollution, which is associated with millions of premature deaths annually [4]. These impacts highlight the close alignment between SLCP mitigation, public health outcomes, and agricultural productivity.
Mitigation measures focused solely on long-term decarbonization, while essential, are insufficient to keep global warming below the 1.5 degrees C threshold [3]. Addressing climate change, therefore, requires a dual policy approach: sustained decarbonization to limit long-term warming, complemented by near-term action targeting SLCPs [3]. Owing to their short atmospheric lifetimes, reductions in SLCPs can yield rapid cooling benefits and could halve the rate of global warming in the near term [3, 5].
However, the sources of SLCP emissions are highly diverse, ranging from biomass and fossil fuel combustion to agriculture, waste management, and industrial and vehicular emissions. In this context, a conventional command-and-control regulatory approach is likely to be both administratively burdensome and ineffective. Effective enforcement would also require high quality emissions data, continuous monitoring, and substantial regulatory capacity, all of which remain constrained in India. Moreover, prescriptive regulations can discourage firms from exceeding compliance thresholds, limiting incentives for innovation and the adoption of advanced abatement technologies [7, 8].
This necessitates exploring alternative policy instruments. First, the government can explicitly prioritize SLCP mitigation and incentivize private investments in abatement technologies. Voluntary carbon markets already support methodologies for activities such as alternative
wetting and drying in paddy cultivation, methane capture from landfills, clean cooking transitions, and sustainable agricultural practices. Strategic purchase of high-integrity credits generated through these activities could help scale mitigation while delivering co-benefits in air quality and rural livelihoods.
Second, market-based regulation through emissions trading systems offers a flexible approach. India’s upcoming Carbon Credit Trading Scheme (CCTS) can be expanded to cover select SLCPs, such as nitrogen oxides and black carbon, from industries. This would allow regulated entities to meet emissions targets at lower cost while encouraging innovation [7, 8]. Additionally, strengthening monitoring, reporting, and verification (MRV) systems is critical to ensuring the credibility of emissions reductions and supporting informed policymaking. Improved data transparency can enhance accountability and build trust among market participants.
With time running out, SLCP mitigation presents a high-impact opportunity to deliver rapid climate benefits. Reductions in SLCPs can eliminate up to 90% of their warming impact within a decade, far faster than CO2 mitigation alone. Incorporating SLCPs into India’s climate policy architecture can complement long-term decarbonization efforts, enhancing policy effectiveness, fostering innovation, and strengthening India’s ability to meet its Paris Agreement commitments.
