Imagine waking up in a world where the air is crisp and clean, the oceans are teeming with life, and the earth’s temperature is steadily dropping. It’s the year 2050, and humanity has finally achieved the unthinkable: a global, zero-carbon economy. Cities are powered entirely by renewable energy, transportation runs on electric and hydrogen fuel cells, and carbon emissions have plummeted to near zero.

This is the utopia that’s driving policymakers, businesses, and individuals to strive for zero-carbon goals. And it’s a future that’s becoming increasingly within reach. In 2015, the Paris Agreement set a global target of limiting warming to well below 2°C and pursuing efforts to limit it to 1.5°C above pre-industrial levels. To achieve this, countries have committed to reducing greenhouse gas emissions to net-zero by the second half of the century.
But what does it mean to have a zero-carbon economy? In essence, it means that the amount of greenhouse gases emitted into the atmosphere is balanced by the amount removed. This can be achieved through a combination of reducing emissions, increasing energy efficiency, and deploying carbon capture and storage technologies. Some countries, like Norway and Sweden, are already close to achieving this goal, with emissions levels that are significantly lower than the global average.

So, how do we get there? One key strategy is to transition to renewable energy sources, such as solar and wind power, which are becoming increasingly cost-competitive with fossil fuels. Governments are also investing in research and development of new clean technologies, such as hydrogen fuel cells and advanced nuclear power. Additionally, many companies are making a public commitment to reach net-zero emissions by 2050, with some, like Amazon and Google, setting even more ambitious targets for the 2030s.
But achieving zero-carbon goals won’t be easy. It will require significant investment, technological innovation, and behavioral change. Governments will need to implement policies that encourage the adoption of clean energy, improve energy efficiency, and support the development of new industries. Businesses will need to reorient their operations to prioritize sustainability and reduce their environmental footprint. And individuals will need to make conscious choices about how they live and work, choosing carbon-neutral options whenever possible.
Despite the challenges, momentum is building. The European Union has set a target of becoming carbon neutral by 2050, and many countries are following suit. The UK, for example, has committed to reducing emissions by 78% by 2035, and New Zealand has set a goal of becoming carbon neutral by 2050.
In this special issue, we explore the latest developments in the pursuit of zero-carbon goals. We speak with industry experts, policymakers, and entrepreneurs who are driving the transition to a low-carbon economy. We also examine the technologies and strategies that are being deployed to achieve this goal, and the opportunities and challenges that lie ahead.
As we look to the future, one thing is clear: achieving zero-carbon goals is no longer a distant dream, but a necessary reality. It’s a challenge that requires collective action, creativity, and determination. But if we work together, we can create a world that’s powered by clean energy, where the air is clean, and the earth’s temperature is under control. The future is within our grasp – it’s time to seize it.
