Carbon capture and storage (CCS) technologies have become an increasingly popular topic in IELTS Writing Task 2 examinations, particularly in questions focusing on environmental solutions and climate change. Based on analysis of past exam papers, this theme has appeared multiple times since 2019 and shows a strong likelihood of recurring in future tests, especially given its relevance to The role of technology in reducing greenhouse gas emissions.

Climate change mitigation strategies have sparked considerable debate, particularly regarding the relative merits of carbon capture and storage (CCS) versus renewable energy investments. While both approaches have their advocates, I believe a combined strategy would be most effective in addressing our environmental challenges.
Proponents of CCS technologies argue that these systems offer an immediate solution to reducing industrial emissions. For instance, the Boundary Dam facility in Canada has demonstrated that CCS can capture up to 90% of CO2 emissions from power plants. Additionally, these technologies allow traditional industries to continue operating while significantly reducing their environmental impact, maintaining economic stability and employment levels.
However, supporters of renewable energy investment, similar to those discussed in renewable energy solutions for climate change, contend that this approach offers a more sustainable long-term solution. Solar and wind power installations provide clean energy without generating additional emissions that require capture and storage. Moreover, renewable energy technology costs have decreased dramatically over the past decade, making them increasingly competitive with fossil fuels.
In my view, both technologies play crucial roles in addressing climate change. While CCS can help manage emissions from existing infrastructure, renewable energy presents a pathway to a zero-emission future. The question of how reducing carbon footprints can prevent global warming necessitates a multi-faceted approach incorporating both solutions.

These days, people have different opinions about how to reduce greenhouse gases. Some think carbon capture technology is the best way, but others believe renewable energy is better. I will discuss both sides and give my opinion.
Carbon capture technology has some good points. First, it can help big factories reduce their pollution quickly. For example, some power plants use this technology to catch CO2 before it goes into the air. Second, it lets companies keep working while being more environmentally friendly, which is important for jobs and the economy.
On the other hand, renewable energy like solar and wind power has many benefits. It makes clean electricity without any pollution, which is better than having to catch and store carbon dioxide. Also, as mentioned in how can renewable energy be made more accessible, these technologies are getting cheaper every year, making them a good choice for many countries.
I think both technologies are important for fighting climate change. We need carbon capture for existing factories, but we should also invest in renewable energy for the future. This way, we can reduce pollution now and have clean energy later.
