Bulk chemical output set to rise 23% by FY30; RE shift cuts costs, emissions: Report
chlor-alkali production
is expected to rise from 9.23 million tonnes in FY24 to 11.5 million tonnes by FY30, marking a 23 per cent growth, while emission intensity from the sector could reduce by 12 per cent over the same period, according to a report by JMK Research & Analytics.
The report said the chlor-alkali segment accounted for over 71 per cent of India's bulk chemical production in FY24. The sector's average emissions intensity was 1.88 tonnes of CO₂ equivalent per tonne of production in FY24, which is projected to reduce to 1.65 tCO₂e/t by FY30.
Under the Greenhouse Gases Emission Intensity Target Rules, 2025, the sector is required to cut its emissions intensity by 2–3 per cent annually starting 2026.
DCM Shriram case study: Cost savings and emission reduction
DCM Shriram, the country's second-largest caustic soda producer, reported a 26 per cent reduction in power costs and 92,000 tonnes of CO₂ abatement in FY24 through a 43.8 MW wind-solar hybrid plant in Bharuch, Gujarat. The project was developed through ReNew Green (GJ Ten) Private Ltd, with DCM holding a 31.2 per cent stake in the group captive model.
The plant generated 250 million units of electricity in FY24 at a power purchase tariff of ₹3.55 per unit. The share of renewable electricity in the company's total consumption rose from 0.22 per cent in FY23 to 23.7 per cent in FY24.
DCM Shriram also commissioned a 12 TPD compressed biogas (CBG) unit in Ajbapur, Uttar Pradesh, with ₹131 crore in investment, including ₹100 crore in
sustainable financing
from Standard Chartered Bank. The unit was commissioned on March 27, 2025.
RE share in energy mix at 41.8%; emissions at 2.42 million tCO₂e
DCM Shriram's total energy consumption in FY24 stood at 46,139 TJ, with renewables accounting for 41.8 per cent, according to the report. Renewable fuels such as biomass, bagasse, ethanol and CBG comprised 42.6 per cent of the renewable share.
The company reported total Scope 1 and 2 emissions of 2.42 million tonnes of CO₂ equivalent in FY24, with an overall emissions intensity of 0.83 tCO₂e per tonne of production. Its chlor-alkali segment had a higher intensity at 2.15 tCO₂e/t, 14 per cent above the national average.
As per the emission intensity rules, DCM Shriram's Kota unit is required to reduce its intensity by 6.8% and the Bharuch unit by 8.3 per cent by FY27.
New RE projects to be commissioned by FY26
The company plans to commission a 68 MW wind-solar hybrid project at its Kota unit by Q4 FY26 in partnership with JSW Renewables. DCM has invested ₹60 crore for a 26 per cent equity stake in the special purpose vehicle. Another 6.6 MW RE capacity will be added at the Bharuch unit by Q1 FY26.
Once operational, these projects are expected to generate ₹430 crore in annual power cost savings and abate 3.3 lakh tonnes of CO₂—up from 92,000 tonnes in FY24.
In FY24, DCM Shriram also used 30.2 million Nm³ of blue hydrogen in place of furnace oil, resulting in an additional 80,095 tonnes of CO₂ abatement.
Other companies scaling clean energy use
Tata Chemicals and Aditya Birla Chemicals are also adopting clean energy. Aditya Birla Chemicals targets a 30 per cent emissions reduction from 2017 levels by FY25, and carbon neutrality by 2050. Tata Chemicals is working to replace 10 per cent of coal with biomass and scale solar and wind capacity.
JMK Research noted that India's chlor-alkali sector faces regulatory and market pressure to decarbonise and improve competitiveness, with
renewable energy
, hybrid systems and
green hydrogen
seen as key strategies.

UP gets Centre's nod to launch AI-powered road safety project
Lucknow: To be executed at zero cost by public sector enterprise ITI Limited and mLogica, the pilot project will focus on mitigating road safety hazards resulting in accidents, vehicle telematics, weather patterns, crash report analysis, and blackspot analysis. The objective of the study is to identify the root causes of road accidents. The research and analytics studies will help the transport department of UP to sharpen its policies and strategy to check fatal car crashes. The Yogi Adityanath govt has already set the foundation for a data-driven administrative model by allocating Rs 10 crore in the state budget for FY 2025–26. Upon successful testing, the AI engine will be scaled up across key transport services—such as the faceless licence and permit system, enforcement modernisation, revenue collection, e-challan system, and the Vahan-Sarathi platform—positioning Uttar Pradesh as a national leader in tech-enabled governance. This will enable transparent, swift, and scientific transport services for citizens. The AI engine will also facilitate interoperability across revenue administration, e-challan processing, and the Vahan-Sarathi databases, enabling automated alerts and risk scoring related to tax liabilities, fee payments, and document validity. Transport commissioner Brajesh Narayan Singh stated that implementation has already begun, with the ITI - mLogica team collaborating with the department's IT, enforcement, and road safety divisions.

ChatGPT 5 might be dropping next week, here's everything we've heard so far
Word is, OpenAI might launch GPT-5 as early as next week. If the chatter holds up, this could be their most powerful model yet combining the best of o3 and 4o into one unified system. Think sharper reasoning, true multimodal support, and the ability to handle complex tasks on its own. Big leap incoming. Sam Altman has more or less confirmed it GPT-5 is coming 'soon.' He said as much on X, and even gave a live demo of the model on This Past Weekend with Theo Von. At one point, he fed it a question he couldn't crack himself. 'This is GPT-5,' he said, as it nailed the answer. His takeaway? 'I felt useless relative to the AI.' Big statement. Explore courses from Top Institutes in Please select course: Select a Course Category Data Analytics MBA Degree Management MCA Public Policy Product Management Cybersecurity PGDM Artificial Intelligence Operations Management Technology Finance Digital Marketing Healthcare healthcare Design Thinking CXO Others Data Science Project Management Data Science others Leadership Skills you'll gain: Data Analysis & Visualization Predictive Analytics & Machine Learning Business Intelligence & Data-Driven Decision Making Analytics Strategy & Implementation Duration: 12 Weeks Indian School of Business Applied Business Analytics Starts on Jun 13, 2024 Get Details Whispers about GPT-5 being tested 'in the wild' have only added fuel to the fire. Word is, OpenAI might make it official in early August and it won't be just one model. Expect a full rollout, with mini and nano versions tailored for different workloads. GPT-5 should land on both ChatGPT and the API, while the leaner nano variant looks set to stay API-only. So, what can you expect from GPT-5? All inclusive OpenAI's aiming to do under the hood finally merge the GPT and o-series models into one unified system. Until now, users had to juggle between models: o3 for reasoning, GPT-4 for math or code. GPT-5 might change that completely. No more picking just one model that does it all. Altman's hinted at this too, calling it 'a system that integrates a lot of our technology.' The idea is to combine o3's logic strength with GPT-4's edge in structured tasks like coding and problem-solving. And from what early testers are saying, it's already hitting near PhD-level performance in heavy reasoning tasks. Multi-Model Upgrade GPT-4o gave us live voice, text, and image support but GPT-5 might take it further. Video processing is apparently on the table, and switching between different input modes is expected to be even more seamless. Basically, the AI feels less like a tool, more like a co-pilot. Memory Improvement Another major jump: context window. While GPT-4o could manage 128K tokens, GPT-5 might push past 256K. That means deeper memory, longer threads, and more coherent multi-session conversations. If true, we're looking at a version that remembers more and feels less 'reset' every time you talk to it. Paging for autonomous AI There's also buzz around GPT-5 unlocking the next phase of AI autonomy. Think: agents that can handle real-world digital tasks end-to-end, without much human input. From using APIs to navigating platforms or tools on your behalf it's being pitched as a smarter, more capable virtual assistant.

Trump's ‘penalty' tariff threat: How much Russian oil does India buy? What are the other alternatives?
Donald Trump's threat of a 'penalty' tariff on India for buying Russian crude oil looms large as New Delhi and Washington try to reach a trade deal. Russia accounted for a mere 0.2 per cent of India's imports of crude oil before the Ukraine war began in February 2022. Today, the South Asian country is among the top buyers of Russian oil. But how did this happen? read more A view shows an oil pump jack outside Almetyevsk, in the Republic of Tatarstan, Russia, July 14, 2025. File Photo/Reuters United States President Donald Trump has increased pressure on India to reach a bilateral trade deal by imposing 25 per cent tariffs on Indian imports. Compared to India, more than 50 countries have lower levies, including Pakistan and Bangladesh at 19 per cent and 20 per cent, respectively. On Wednesday (July 30), Trump announced 25 per cent tariffs on goods imported from India from August 1 and threatened a 'penalty' tariff for buying Russian crude oil. In another scathing attack, the US president said that India and Russia could 'take their dead economies down together.' STORY CONTINUES BELOW THIS AD As Trump goes after New Delhi for its trade with Moscow, particularly crude, can India give up Russian oil? Let's take a closer look. How much Russian oil does India buy? India's oil purchases from Russia have seen a hike since Moscow invaded Ukraine in February 2022. In fact, China and India are the top two buyers of Russian oil. Before the Ukraine invasion in early 2022, Russia accounted for a mere 0.2 per cent of India's imports of crude oil. India purchased 68,000 barrels per day of crude oil from Russia in January 2022, PTI reported, citing global real-time data and analytics provider Kpler. By June 2022, Russia replaced Iraq to become India's top oil supplier. Moscow supplied 1.12 million barrels per day (bpd) to India, compared to 993,000 bpd from Iraq and 695,000 bpd from Saudi Arabia. The turnabout came as the West sanctioned Russia over its war in Ukraine. This led Moscow to cut crude prices, with discounts reaching $40 per barrel at one point. India ramped up its purchase of discounted crude oil from Russia. In May 2023, Russian oil imports peaked at 2.15 million bpd. A man stands at an Indian Oil fuel station in Sonipat, March 5, 2025. India's oil purchase from Russia has increased in the past three years. File Photo/Reuters India's import of crude oil from Russia has not fallen below 1.4 million bpd. While prices have varied, New Delhi has since bought Russian oil worth approximately $275 billion each year, as per a New York Times (NYT) report. STORY CONTINUES BELOW THIS AD Since the Western sanctions on Russian oil, China has purchased 47 per cent of Russia's crude exports, followed by India (38 per cent), the European Union (six per cent), and Turkiye (six per cent), according to the Centre for Research on Energy and Clean Air (CREA) analysis. Last month, India's crude oil imports from Russia rose to an 11-month high of about 2.08 million barrels per day. 'In June, India remained the second-largest purchaser of Russian fossil fuels, importing fossil fuels worth 4.5 billion euros. Crude oil accounted for 80 per cent (3.6 billion euros) of these imports,' as per the CREA data, reported by CNBC-TV18. The oil companies in India refined some of their imported crude oil for domestic consumption, while the rest was exported as diesel and other products, including to Europe. The cheap Russian oil helped India keep inflation in check and the economy stable amid growing geopolitical tensions. India has maintained a neutral stance in Russia's war with Ukraine. It has also defended its trade with Moscow, citing historical ties and energy needs. STORY CONTINUES BELOW THIS AD Union Minister of Petroleum and Natural Gas Hardeep Singh Puri has also repeatedly stated that global oil prices would have significantly spiked if India had not purchased Russian oil. Can India cease buying Russian oil? As Trump presses New Delhi, Indian state refiners have stopped buying Russian oil in the past week, industry sources told Reuters. On July 14, Trump had threatened 100 per cent tariffs on countries buying Russian oil unless Moscow reached a peace deal with Ukraine. Puri previously asserted that India was not perturbed by the US president's threat, as oil markets remain well supplied. 'Russia is 10 per cent of global production. We have the analysis that if Russia were not included, the prices would have gone to $130 a barrel. Even Turkey, China, Brazil and even the EU have bought oil and gas from Russia,' the minister said. Puri also warned an uptick in oil prices if Russian crude was shunned. 'There are two possibilities: one, the whole world consumes 10 per cent less — which means some people won't get heating in winter; some won't get air conditioning in summer; some of the transport will stop flying. Or, you start buying more from the remaining 90 per cent (suppliers). You know what that would do to prices? The prices would skyrocket,' he said. STORY CONTINUES BELOW THIS AD If Trump goes through with his threat of a 'penalty' tariff, it would become difficult for India to continue buying Russian oil, the discount on which has decreased. In such a case, Indian refiners will have to return to their traditional crude suppliers in West Asia and seek new ones such as Brazil. However, these new barrels would bear a higher cost, ranging around $4-5/barrel, as per an Economic Times report. India has also enhanced its crude imports from the US. However, it is not easy for the South Asian country to ditch Russian oil, partly because its refineries are configured for Russia's denser and more sulfurous fuel, reported NYT. 'The pivot away from Russia — if forced — will be costly, complex and politically fraught,' Kpler wrote in a note this week. With inputs from agencies
