According to a new edition of the International Energy Agency’s (IEA) historic Net Zero Roadmap, achieving net zero greenhouse gas emissions from the global energy sector and keeping global warming to 1.5 degrees Celsius is still possible. However, momentum needs to pick up quickly in many areas.
According to the IEA, the roadmap emphasized the need for greater ambition and more robust international cooperation to fulfill the world’s climate goals.
Even while fossil fuel investments have surged and emissions have remained high, record increases in solar power capacity and sales of electric vehicles show that achieving net-zero emissions by the middle of the century is still feasible.
By 2030, it is anticipated that these technologies will account for one-third of the emissions reductions required. Additionally, the contribution of yet-to-be-commercialized technologies to emissions reduction has decreased from almost 50% in 2021 to about 35% in the 2023 update.
By 2030, the amended plan asks for a tripling of the world’s renewable energy capacity and a doubling of the rate at which energy efficiency is being improved annually. It also calls for a 75% decrease in methane emissions from the energy sector and a substantial increase in the sales of electric cars and heat pumps. By the end of the decade, it is anticipated that these measures, which are based on tested and frequently affordable technologies, will have achieved over 80% of the required emissions reductions.
The roadmap also emphasizes the necessity of a fair transition that takes into consideration local conditions. To give developing and emerging economies more time, rich economies, for instance, should achieve net zero sooner. By 2030, the roadmap also aims to give everyone access to modern energy sources. To achieve this goal, an annual investment of close to $45 billion—or slightly more than 1% of the energy sector’s investment—is needed.
However, most nations need to increase investments significantly and move up their target net zero dates, particularly in growing and developing economies. By the early 2030s, it is anticipated that global renewable energy spending will increase from $1.8 trillion in 2023 to $4.5 trillion annually.
According to the revised scenario, demand for fossil fuels would decrease by 25% by 2030 and by 80% by 2050. As a result, there is no longer a need for more long-term upstream oil and gas projects, coal mines, or unabated power plants. However, some current oil and gas assets still require investments.
The research emphasizes the significance of more resilient and diverse supply chains for essential minerals and renewable energy technologies. International cooperation is essential because if efforts are not stepped up between now and 2030, the 1.5 degree Celsius objective may be dependent on unproven carbon removal technology.
According to the analysis, if action is delayed, it may become necessary to remove approximately 5 billion tonnes of carbon dioxide from the atmosphere every year over the second part of this century, making it difficult to bring global temperatures back to 1.5 degrees Celsius.
“The world must act rapidly to maintain the target of keeping global warming to 1.5 degrees Celsius. The good news is that we are aware of what must be done and how to do it. According to the most recent data and analysis, our 2023 Net Zero Roadmap outlines a course for progress, according to IEA executive director Fatih Birol. But we also have a very clear message: success depends on effective global cooperation. Given the magnitude of the problem at hand, governments must keep climate and geopolitics apart
