In 2022, the world’s carbon emissions reached an all-time high, as noted in a recent report by the International Energy Agency (IEA) on March 2nd, 2023, recording 36.8 billion tons of CO2 emissions, up nearly 1% compared to 2021. The increasing emissions are driven by fossil fuel consumption, which is hindering the world’s efforts to achieve climate goals.
As a company specialized in providing solar energy solutions on roofs, Tona Syntegra Solar (TSS) is working with businesses to build and install rooftop solar power systems, contributing to reducing CO2 emissions for years to come.
From 2011 to 2021, carbon emissions from energy use worldwide continued to rise, with an increase of 6.21% from 2011 to 2021. CO2is released when burning fossil fuels such as oil, coal, or natural gas to power cars, planes, homes, and factories.
The largest increase in emissions in 2022 came from the electricity and heat sector, with emissions rising by 1.8%. According to the IEA, severe weather events including droughts and heat waves, along with a large number of nuclear power plant outages, were among the factors contributing to the increase in emissions last year.
Natural gas emissions decreased by 1.6% in 2022 due to tightened supply and the impact of the Russia-Ukraine conflict, but emissions from coal offset this reduction by 1.6%. Meanwhile, emissions from oil saw an increase of 2.5%, but remained lower than pre-Covid-19 levels.
As the aviation and tourism industries recover from the pandemic, carbon emissions from burning fossil fuels have increased by 2.5%, with about half of this increase coming from the aviation industry.
The development of renewable energy, electric cars, heat pumps, etc. has helped reduce global carbon emissions by 550 million tons. Without this development, the increase in emissions could be three times higher.
Last year, the global energy crisis caused by the Russia – Ukraine conflict created unprecedented momentum for renewable energy, and the IEA predicted that renewable energy would become the largest source of electricity in the world by 2025.
According to a study by PwC, Vietnam reduced its carbon intensity by 3.4% in 2021. Another country in the Southeast Asia region that also achieved an impressive reduction is Malaysia, with a 4% decrease.
Overall, Vietnam’s carbon emissions from primary energy use are still very low. The total carbon emissions from Vietnam’s primary energy use in 2021 was 272.7 million tonnes, accounting for only 0.8% of the world’s total, and the average carbon emissions per capita were only 2.77 tonnes/person, which is much lower than many other countries in the region and the world.
The total carbon emissions in Vietnam in 2021 from all sources (including energy industry, CO2 emissions from explosions, methane emissions in carbon equivalent, and CO2 emissions from industrial processes) was 339.8 million tonnes (0.9% of the world’s total), and the average carbon emissions per capita were 3.447 tonnes/person, which is 24.61% higher than the total carbon emissions from primary energy use alone.
In response to the increasing CO2 emissions, experts have proposed several solutions such as enhancing the use of energy-saving methods, efficient energy use based on economic restructuring, and other specific solutions for each sector.
With a capacity of 60+ MWp, Tona Syntegra Solar’s EPC and O&M projects contribute about 81 million kWh of electricity production and reduce approximately 39 thousand tonnes of CO2 emissions per year. TSS is aiming to develop more projects in 2023 and the following years to increase these numbers. TSS collaborates with its customers to work towards the common goal of achieving net-zero emissions by 2050.
