COVID-19 cut carbon emissions but not enough to dent global warming

The lockdown-related fall in emissions is just a tiny blip on the long-term graph. We need a sustained flattening of the curve – WMO Secretary-General Petteri Taalas.

Many eagerly awaited to know the impact of the novel coronavirus disease (COVID-19) pandemic on the climate. Did the widespread shutdowns and drastic reduction in industrial activities lead reduced greenhouse gas (GHG) emission?

According to preliminary estimates by the World Meteorological Organization (WMO), the annual global carbon dioxide (CO2) emission reduced 4.2-7.5 per cent in 2020.

WMO?? Global Carbon Project has estimated that ??uring the most intense period of the shutdown, daily CO2 emissions may have been reduced by up to 17 per cent globally due to the confinement of the population??

But there is not much to cheer about: WMO calls it a blip on the planet?? uncontrolled emission scenario.

According to the estimate report:

At the global scale, an emissions reduction at this scale will not cause atmospheric CO2 to go down. CO2 will continue to go up, though at a slightly reduced pace (0.08-0.23 ppm per year lower).

The natural inter-annual variability in CO2 emission is 1 part per million (ppm). It means the impact of the pandemic on CO2 reduction is not significant and not even higher than the natural variability figure.

??his means that on the short-term the impact of the COVID-19 confinements cannot be distinguished from natural variability,??according to WMO.

The Earth?? atmosphere has a heavy concentration of GHGs including CO2. The temporary reduction in emission due to the pandemic would not curb global warming and resultant climate change.

Rather, the GHG emission would continue to rise in 2020 as well. Last year the global average of CO2 crossed the threshold of 410 ppm.

Taalas said:

Carbon dioxide remains in the atmosphere for centuries and in the ocean for even longer. The last time the Earth experienced a comparable concentration of CO2 was 3-5 million years ago, when the temperature was 2-3?C warmer and sea level was 10-20 meters higher than now. But there weren?? 7.7 billion inhabitants.

More to it, it took just four years for the level to cross this threshold from 400 ppm in 2015. ??uch a rate of increase has never been seen in the history of our records. The lockdown-related fall in emissions is just a tiny blip on the long-term graph. We need a sustained flattening of the curve,??the WMO secretary-general added.

??he annual globally averaged level of carbon dioxide was about 410.5 parts per million (ppm) in 2019, up from 407.9 parts ppm in 2018, having crossed the 400 parts per million benchmark in 2015. The increase in CO2 from 2018 to 2019 was larger than that observed from 2017 to 2018 and also larger than the average over the last decade,??according to the WMO bulletin.

Nuvoco Vistas Corporation Limited is celebrating a decade of operations under the theme ‘Dus Saal Bemisaal’, highlighting its expansion in India’s building materials sector. The company has grown from a single cement manufacturing facility into a diversified organisation operating across cement, ready-mix concrete (RMC) and modern building materials.

The company’s journey began in 2014 when its parent, Nirma Group, commissioned a 2 million metric tonnes per annum (MMTPA) greenfield cement plant at Nimbol, Rajasthan. A major milestone followed in October 2016 with the acquisition of Lafarge India, significantly expanding its manufacturing footprint.

Nuvoco strengthened its market presence through the acquisition of Emami Cement, now NU Vista Limited, in 2020, followed by its public listing in 2021. In April 2025, the company added Vadraj Cement to its portfolio, strengthening its presence in western India.

Nuvoco has an operating cement capacity of 27 MMTPA and 14 manufacturing units, including the Kutch and Sachana facilities in Gujarat, which are in advanced stages of completion. It also operates 58 ready-mix concrete plants across India and offers a range of modern building materials.

The company aims to increase its cement capacity to 35 MMTPA by FY2027-28, representing approximately 15-fold growth over the decade.

Reflecting on the milestone, Hiren Patel, Chairman, Nuvoco Vistas Corporation Limited, said, “From our beginnings at Nimbol to the organisation we are today, every milestone has added a new chapter to Nuvoco’s journey and strengthened our belief in building for the long term.”

The company continues to focus on capacity expansion, operational efficiency, innovation and sustainability while strengthening its position in India’s construction materials market.

Jammu and Kashmir government has notified the City Gas Distribution (CGD) Policy, 2026, following its approval by the Council of Ministers headed by Chief Minister Omar Abdullah. The policy sets out a phased framework for expanding Piped Natural Gas (PNG) and Compressed Natural Gas (CNG) access for households, businesses, industries and the transport sector across the Union Territory.

CGD networks will be expanded in phases across all 20 districts, with the aim of bringing reliable natural gas closer to consumers and supporting a gradual shift from conventional fuels. The government said the policy is designed to improve energy access while creating an investor-friendly and time-bound environment for gas distribution projects.

The policy provides for single-window and time-bound clearances, streamlined procedures for setting up CNG stations and standardised norms for the Right of Way. These measures are intended to reduce procedural delays, simplify project implementation and facilitate investment in natural gas infrastructure.

It also prioritises gas connectivity for major industrial estates, including those in Kathua, Samba and Pulwama. Improved access to natural gas is expected to support industrial activity, enhance energy efficiency and help businesses manage fuel costs, while strengthening their competitiveness and encouraging investment in the clean-energy sector.

The policy is also expected to create opportunities for local employment, apprenticeships and skill development in the construction, operation and maintenance of gas distribution networks and related services. Abdullah described the measure as an important step towards cleaner growth, sustainable development and a modern energy ecosystem in Jammu and Kashmir, saying it would expand reliable energy access and support industry and investment.

JSW Cement has commissioned an additional 1 MTPA grinding unit at Nagaur in Rajasthan. MTPA refers to million tonnes per annum. The commissioning has increased the company’s total cement grinding capacity to 25.10 MTPA, while its total clinker manufacturing capacity, including capacity at its joint venture JSW Cement FZC, stands at 9.74 MTPA.

The company began operations in North India in March 2026 with the Nagaur Integrated Plant, which comprised a 3.30 MTPA clinkerisation unit and a 2.50 MTPA cement grinding unit. Following the latest commissioning, the plant’s total cement grinding capacity has risen to 3.50 MTPA.

The expanded facility is expected to strengthen JSW Cement’s ability to serve cement demand across Rajasthan, Haryana, Punjab and the National Capital Region. The project has been funded through a combination of equity and long-term debt, according to the company.

During the quarter ended 30 September 2026, JSW Cement also commissioned an Alternate Fuel Handling System and a Waste Heat Recovery System (WHRS) at the Nagaur Integrated Plant. The company said the additions formed part of its broader effort to improve operational efficiency at the facility.

Nilesh Narwekar, chief executive officer of JSW Cement, said the additional grinding capacity was a strategic priority that would support the company’s expansion in North India. He added that the unit had been commissioned within the expected timeline, reflecting the company’s project execution capabilities, and that the alternate fuel and waste heat recovery systems were expected to substantially reduce production costs going forward.
