India's auto-makers have agreed to new Corporate Average Fuel Efficiency (CAFE-III) targets, aiming to reduce CO2 emissions from 113 g/km to 77 g/km by 2031-32. While seemingly ambitious, the framework's flexible design, including credits for higher ethanol blending and incremental efficiency technologies, may weaken compliance and slow the essential transition to electric mobility. Super-credits for EVs and credit banking further allow manufacturers to meet targets without a structural shift. The article argues that without sharper incentives for electrification, CAFE-III risks becoming a paper exercise rather than driving meaningful change in emissions reduction, energy security, and climate mitigation.
- India's auto-makers have agreed to new Corporate Average Fuel Efficiency (CAFE-III) targets to reduce CO2 emissions.

A new modelling study published in Environmental Research: Climate indicates that India's forests could nearly double their carbon storage by 2100 under current greenhouse gas emission trends. The study projects vegetation carbon biomass to rise by 35% under low-emissions, 62% under medium, and 97% under high-emissions scenarios. This increase is primarily driven by rising precipitation and elevated atmospheric CO2, enhancing photosynthesis and water-use efficiency. The largest relative increases are projected in desert and semi-arid zones (Rajasthan, Gujarat, Madhya Pradesh), rather than established forest heartlands. Researchers caution that these gains may mask deeper stresses and disruptive forces like deforestation, fires, and pest outbreaks.
- India's forests have the potential to significantly increase carbon storage by 2100, possibly nearly doubling current levels.
- Projected increases in vegetation carbon biomass vary significantly across emission scenarios, with the highest under a high-emissions pathway.
- The primary drivers for increased carbon storage are higher rainfall and elevated atmospheric CO2, which boost tree growth and efficiency.
New research confirms that genetically modified mosquitoes can suppress malaria parasites from real-world infections, moving closer to 'Transmission Zero.' Using the CRISPR-Cas9 gene-editing tool, scientists have developed gene drives that either suppress mosquito populations by causing sterility or modify mosquitoes to prevent malaria parasite development without killing the mosquito. A recent Nature study, led by Tibebu Habtewold and Dickson Lwetoijera in Tanzania, demonstrated the effectiveness of modified Anopheles gambiae mosquitoes in blocking malaria parasites from infected children's blood. The research emphasizes the need for extensive ecological risk assessment, regulatory review, and community engagement before wild release, acknowledging that gene drives are an additional tool, not a standalone solution.
- Genetically modified mosquitoes using gene drive technology show potential for malaria control by suppressing parasite transmission.
- Two main types of gene drives are being developed: population suppression (causing sterility) and population modification (preventing parasite development).
- A recent study in Nature demonstrated that modified Anopheles gambiae mosquitoes could block malaria parasites from real-world infections in endemic African settings.
India's March retail inflation (CPI) at 3.4% appears benign, but the Wholesale Price Index (WPI) climbed to a 38-month high of 3.88%, indicating underlying pressures. This divergence is partly due to the CPI's new 2024 base year versus WPI's 2011-12 base year. Rising input costs, especially fuel prices amplified by the rupee's depreciation against the US dollar and the US-Israeli war on Iran disrupting supply chains, are key drivers of imported inflation. While firms have absorbed costs, this is unsustainable. Contraction in exports and imports suggests war-induced supply disruptions. The article warns of emerging stagflationary risks and underscores India's vulnerability as an oil-import-dependent economy, urging a shift to renewable energy.
