Since the dawn of the first industrial revolution, factory chimneys have expelled millions of tons of toxic gases into the atmosphere. Roughly three centuries and an equal number of industrial revolutions later, we are at a tipping point where industrial processes and fossil fuel combustion together accounted for 78% of the rise in total greenhouse gas emissions between 1970 and 2011.

The impact of this dramatic transformation is evident from an ongoing temperature analysis by NASA, which reported that the average global temperature has increased by a little over 1 degree Celsius since 1880. Hidden inside this apparently harmless information is the fact that about two-thirds of the warming has happened since 1975, a dramatically elevated rate of roughly 0.15-0.20 degree Celsius per decade.  

With global carbon footprints increasing at a steep rate, while carbon emission allowances narrow even further, industries are left with no choice but to revitalize their commitments towards sustainability through an “actions speak louder than words” approach. To achieve a Net Zero Carbon future by 2050, the ability to engineer and develop net zero products thus becomes paramount.

What are Net-Zero Products?

Overall, Net Zero refers to the goal of reducing greenhouse gas emissions to zero by balancing the amount released into the atmosphere from industrial sources with the amount that is removed and stored in carbon sinks. As greenhouse gases are the primary cause of global warming, an unabated rise in their emissions can spell catastrophic climate change for the world at large.

Products and services that are designed to achieve this target goal of carbon neutrality are referred to as “Net Zero Products”.

These include, among others:

  • Renewable energy systems
  • Greenhouse gas removal technology
  • Green transportation
  • Green buildings and cities
  • Strategic carbon advisory services

The carbon neutrality focus for Net Zero Products is achieved through an efficient carbon footprint assessment and carbon reduction strategies across the product lifecycle at an organizational level [Figure 1].

This Energy Assessment [Figure 2] starts with an audit, which is then followed by the preparation of an Assessment Report, and the creation of a subsequent Implementation Roadmap, which is then subsequently published. The process is then reinitiated.

Net-Zero by 2050 – A Historical Perspective

In an act of game-changing legislature, the UK became the first major economy to advocate for net-zero. They advocated for changes to the long-term targets in the Climate Change Act of 2008, shifting it to the goal we all know today as net-zero by 2050. This was in accordance with the Paris Agreement, a binding global treaty on climate change mitigation, adaptation, and related financing.

While the agreement itself did not use the term “net-zero”, in recent years governments worldwide have realized the sheer importance of net-zero goals. Based on research conducted by the Intergovernmental Panel on Climate Change (IPCC) in 2018, it was found that global warming must be limited to a maximum of 1.5 degrees Celsius if the world is to prevent catastrophic climate change. The key takeaways from the IPCC report are that the:

  • Global net level of human-caused emissions of CO2 must decline by about 45% from the 2010 levels by the year 2030, aiming to reach Net Zero by around 2050, and
  • Any remaining emissions would have to be squared-off by removing an equal amount of carbon dioxide from the air.

While the UK was the first economy to do so, as of January 2021, five countries – Denmark, France, Hungary, Sweden, and New Zealand – have also passed Net Zero legislations. Additionally, in its European Green Deal for 2019, the European Union took a major initiative by enumerating a net-zero target for 2050, further cementing its stance on sustainable development 

Meanwhile, other countries have either revised their Nationally Determined Contributions (NDC), proposed new legislation, or shown the desire to achieve net-zero by 2050. A particularly prominent example came in the form of President Xi Jinping announcing in 2020 that China would strive to become net carbon-neutral by the year 2060. As the world’s largest emitter of carbon emissions, if China were to achieve this goal, it would be an immeasurable contribution towards global carbon neutrality.

India is also considering ways to meet the 2050 target, and there are discussions among senior bureaucrats and responsible ministries on whether this can be achieved by 2047, the centenary of its independence. While such a measure would involve a major overhaul of its coal-fired economy, the country seems to be gearing up to meet the challenges involved in the transition. 

The trend the world over, therefore, seems to be in favor of controlling and reducing carbon emissions, and Net Zero products have a significant role in this direction.

Towards Net Zero Products – A Reality Within Reach

Creating a truly Net Zero future through the adoption of Net Zero products involves leveraging new opportunities and overcoming challenges inherent to legacy industrial structures and processes. A switch to renewable energy resources (solar, wind, and water) for power generation is therefore a key step here, by directly reducing carbon emissions and as the most visible way for industries to underscore their commitment to a sustainable future. Additional investments on innovative energy solutions that are both technologically viable and offer an economical alternative for conventional fuel-dependent sectors would have a further significant impact in this direction.

Adopting a Circular Economy approach, which aims to gradually decouple growth from the consumption of finite resources, is another key step for a Net Zero world. As opposed to the linear ‘take-make-waste’ model, a redefinition of new product development (NPD) methodologies in alignment with the Circular Economy principles would result in a sustainable consumption paradigm and a cleaner Earth. Further, value engineering methods can be leveraged to drive design optimization for delivering light weight, reusable, and recyclable products, which would go a long way towards meeting net zero targets.

Transitioning towards Net Zero products would also boost the adoption of effective water and waste management, while providing an impetus for the expansion of green transportation (like a transition towards electric aircrafts) and green buildings. This renewed focus on efficient and sustainable resource utilization would be further deepened by smarter energy and emission management, and a revitalized interest in a Product-as-a-Service approach for driving enhanced outcomes.

Innovative technologies such as Direct Air Capture (DAC) and Bio-Energy with Carbon Capture and Storage (BECCS) can also be viable tools in the journey towards a sustainable future, though further testing remains to be undertaken.

Sustaining the Future – Towards a Net Zero Tomorrow

With the global movement for Net Zero growing ever stronger, a sustainable economic future – especially one in a post-COVID world – is one that has witnessed industries rise to the occasion. Several companies have already put their best foot forward and are leveraging available engineering expertise, global experience, and resources to address the challenges in ensuring a sustainable future. Significant investments are underway in low-carbon engineering applications, with a focus on pioneering new solutions and products that can help businesses achieve Net Zero at a rapid pace.

By acting today in creating net-zero solutions and innovations, achieving Net Zero by 2050 will be an eminently attainable target – one that will help define and secure the future for our children, and our children’s children.
